Automatic Faucet
Q: What is a sensor faucet, and how does it work?
A: Sensor faucet is a touchless faucet that uses an infrared sensor to detect hand movement. When you place your hands within the specified range, the water turns on automatically, and it stops when you remove your hands. This means there’s no need to touch the faucet, helping reduce germ contamination and improve hygiene.
✔ Helps reduce contact with germs
✔ Fast response and easy to use
✔ Adjustable sensing/detection range
Q: Do sensor faucets really save water? About what percentage?
A: Yes!
A sensor faucet works only when it’s actually being used, so it can reduce unnecessary water flow—saving up to around 60–70% compared with a standard manual faucet that you turn on and off yourself, where people often forget to shut the water off or don’t close it completely.
As a result: ✔ Lower water bills ✔ More efficient water use ✔ Less waste
Q: What types of places are sensor faucets suitable for?
A: Ideal for places that require high hygiene standards and heavy daily use, such as:
📍 Industrial factories
📍 Food & pharmaceutical factories (GMP/HACCP-compliant)
📍 Hospitals and clinics
📍 Schools and universities
📍 Shopping malls / public restrooms
📍 Hotels and offices that want a modern, fresh image
Because sensor faucets help reduce touchpoints, prevent cross-contamination, and are built for long-lasting use.
Q:Which is better: battery-powered or electric (wired)?
A: Both options have their own advantages:
🔋 Battery-powered:
• Easy to install—no wiring required
• Ideal for new installations or replacing an existing faucet
• Long battery life (typically 1–2 years, depending on usage)
⚡ AC/DC adapter (wired power):
• Best for buildings where a power outlet is available
• No need to replace batteries
• Ideal for high-traffic areas with continuous/heavy use
Note: Many models support both power options in one unit, so you can choose whichever is more convenient.
Q: Is a sensor faucet difficult to install? Do I need to run electrical wiring?
A: It’s easy to install as a replacement for an existing faucet, using the same standard mounting hole (1 inch / 25–35 mm).
💡 If using battery power: No electrical wiring is needed.
💡 If using wired power (AC/DC adapter): You can plug it into a standard outlet or run the cable neatly inside the counter.
Q: What type of batteries does it use, and how long do they last?
A: Most sensor faucets typically use 4 AA or AAA alkaline batteries.
📌 Average battery life: about 1–2 years, depending on usage frequency.
📌 The system usually has a low-battery indicator/alert, so you’ll know when it’s time to replace them.
Q: What should I do if the faucet doesn’t dispense water, or if it keeps running continuously?
A: You can try the following basic checks:
• Check the batteries — they may be running low.
• Clean the sensor — dirt or water droplets on the sensor window can interfere with detection.
• Check the water filter system — if a filter is installed, it may be clogged or affecting water flow.

Automatic Urinal Flusher
Q: How does a urinal sensor flush valve work?
A: It works using an infrared system to detect users. When a user stands in front of the toilet, the system prepares and dispenses water once. When the user walks away, the system automatically dispenses water again for a second flush, keeping the toilet clean at all times without needing manual contact.
Q: Does it really help solve the problem of "smelly bathroom"?
A: It helps a lot. The main cause of bad odors is users "forgetting to flush" or not flushing properly. The sensor flush valve automatically performs this function every time, keeping the urinal clean and reducing the accumulation of stains and unpleasant odors by 100%.
Q: Why are Hygienic sensor flush valves more cost-effective than conventional push-button flush valves?
A: Besides creating a modern and clean image for the place, it's also much more durable than push-type dispensers which are often damaged by foot pressure or excessive force. With a 3-year warranty, it helps reduce long-term maintenance costs.
Q: What type of location is it suitable for?
A: It is highly suitable for public restrooms, shopping malls, gas stations, factories, hospitals, and office buildings with high user traffic, especially for organizations looking to elevate their hygiene (Hygienic) standards to a higher level.
Q: Are there models that are compatible with existing urinals, or do I need to install new pipes?
A: We have both exposed type models, which can be installed as a direct replacement for existing push-button flush valves without needing to dismantle the wall, and built-in type models for new renovations that emphasize aesthetics and concealing the plumbing system.
Q: What water pressure is required for a sensor-activated flush valve?
A: The recommended water pressure is 0.5–6 bar, which aligns with standard water pump systems.
Stable and consistent water pressure ensures effective cleaning performance and allows the sensor to operate at its full efficiency.
Battery-powered vs. electric system: Which is better for your urinal?
A:
• Alkaline battery system: Most popular for bathroom renovations because it requires no wiring; simply insert batteries and it's ready to use.
• Electrical system: Suitable for new buildings with existing electrical systems, for convenience as there's no need to replace batteries.
• Most Hygienic models support both systems, or you can ask our sales team to choose the most suitable model.
Q: How long does one set of batteries last?
A: Our flush valve uses 4 AA or AAA alkaline batteries. It can last approximately 1-2 years (or about 200,000-300,000 flushes, depending on the brand and type of alkaline batteries). It also has a low battery warning light.
Q: What should I do if the sensor isn't working or the water keeps flowing?
A: First, please check...
1. Are the batteries dead?
2. Is the water filter clogged? (There may be pipe debris blocking it.)
If the initial troubleshooting doesn't resolve the issue, please contact the Hygienic service center for immediate on-site service. Our products come with a 3-year warranty and all parts are readily available.
Automatic Hand Dryer
Q: Why are hand dryers more cost-effective than using paper towels?
A: Hand dryers significantly reduce wasteful expenses . A one-time investment can recoup the cost within 3-6 months, especially when compared to the constant need to purchase refillable tissues. They also reduce the labor costs for housekeepers in collecting used tissues.
Q: How does the "Jet" hand dryer differ from the regular model?
A: The jet model uses a high-speed motor to blow strong air to remove water from hands, drying them completely within 7-10 seconds , which is three times faster than regular models. It's ideal for high-traffic areas where speed is crucial.
Q: Do hand dryers really help reduce germs?
A: That's true. Because it's a 100% touchless system, it reduces the risk of contact with germs from the paper handle. In addition, high-end hygienic hand dryers have an air filtration system that blows out clean air, ensuring hygiene.
Q: Which model should I choose to suit the location?
A:
• Shopping malls / Airports / Large offices:
We recommend brushless motor models or Jet Dryers (such as X-PS-505, X-PS-506) because they are highly durable, designed for heavy usage, and provide fast drying performance.
• Restaurants / Cafés / Clinics:
Standard models (such as X-PS-501) are sufficient. They are cost-effective and feature a sleek design that blends well with interior décor.
Q: Are hand dryers noisy and disruptive?
A: Hygienic's new hand dryers are designed to be quieter than older models. In particular, the brushless motor models operate more quietly and smoothly than conventional motors, making them ideal for environments requiring peace and quiet.
Q: Does it consume a lot of electricity?
A: The new hand dryers use energy-saving technology. They only operate for short periods (approximately 10-15 seconds per use). When calculated, the electricity cost per use is very low (less than 1 satang per blow).
Q: Is the installation difficult? What do I need to prepare?
A: Installation is easy; simply mount the device to the wall and plug it in, or connect the power cord to a power outlet. The product comes with a complete installation kit. If you are in our service area, we have an on-site service team available to provide advice or install it for you.
Automatic Alcohol Dispenser
Q: Does this device work with "gel" or "liquid" alcohol?
A: Hygienic's standard models (such as HAS-003/S) are designed specifically for liquid alcohol. They dispense a fine spray that spreads evenly across the palms, dries quickly, and is non-sticky.
• Note: For use with gels or liquid soaps, you must change the pump head to the "drop" type. Please inform our sales staff to change the head to suit your needs.
Q: How accurate is the 2-in-1 alcohol spray (with temperature measurement function)?
A: The HAS-005/S model is highly accurate. It operates in two modes: spraying disinfectant and measuring palm temperature. It also provides an immediate alarm if a high temperature is detected, helping to quickly screen people entering buildings and reduce congestion at the entrance.
Q: How many times can a 1-liter capacity be used? How often does it need to be refilled?
A: The tank has a capacity of 1,000–1,200 ml, allowing approximately 1,000–1,200 spray cycles per refill.
It is ideal for high-traffic areas such as restaurant entrances or offices, as it reduces the need for frequent refilling throughout the day.
Q: Do I need to drill into the wall? Is a stand sold separately?
A: There's no need to drill into the wall if you purchase it with the HSTAND01 floor stand (aluminum alloy), which is strong, aesthetically pleasing, and easy to move to different screening locations. Alternatively, if you prefer wall mounting, a complete installation kit is included.
Q: Does it use batteries or plug into a power outlet?
A: Our unit is designed as a hybrid system.
• Battery-powered: Uses 4 C-size alkaline batteries, allowing installation anywhere without electrical wiring.
• Plug-in option: Equipped with a DC 6V adapter input for locations that require continuous power, such as employee time-clock areas.
Q: Do the spray nozzles clog easily? How can I fix that?
A: Clogged nozzles are usually caused by using the wrong type of "gel." However, this problem is much less common when using alcohol-based hand sanitizer. If the spray stops working, you can easily remove the nozzle and wash it with warm water to dissolve any dirt yourself.
Automatic Soap Dispenser
Q: Can this device be used with "foaming soap"?
A: This model is a drop-type dispenser, designed only for liquid soap, alcohol gel, or dishwashing liquid.
• Caution: Not suitable for use with "foam" type soaps. (If you want to use foam, you must choose the specific "Foam Soap Dispenser" model to ensure the pump head creates smooth and creamy foam.)
Q: Does it really help save soap?
A: That’s correct. The sensor system dispenses a precise amount of liquid per handwash (approximately 0.8–1 ml), which helps prevent misuse or excessive dispensing.
As a result, it can reduce liquid consumption by 30–50% per month.
Q: What is the tank capacity? How often do I need to refill it?
A: The tank has a large capacity of 1,000–1,200 ml (depending on the model), supporting over 1,000 uses per refill.
It is ideal for public restrooms or offices, as it significantly reduces the need for frequent refilling and saves housekeeping time.บ
Q: Is it difficult to install? Do I need to drill through the tiles?
A: The package includes standard mounting hardware (screws and wall plugs). Drilling provides the most secure installation.
However, if drilling is not preferred, you can also install the unit using heavy-duty construction adhesive or high-strength double-sided tape (for smooth surfaces).
Q: Do the batteries run out quickly?
A: The unit uses 4 C-size alkaline batteries and can operate for approximately 1 year (or an average of 30,000–50,000 activations), eliminating the need for complicated electrical wiring.
Q: What should I do if the dispenser nozzle is clogged or the liquid isn't coming out?
A: This problem is usually caused by dried liquid soap buildup at the end of the drain. The solution is to pour warm water into the tank and run the machine to flush out the soap residue. We recommend doing this once a month to extend the lifespan of the drain.
Automatic Foam Dispenser
Q: Does it only work with "foaming agent"? Can I use regular liquid soap?
A: You can use regular liquid soap, but you need to mix it with water in a ratio of 1:3 to 1:5 (1 part soap to 3-5 parts water) and shake well. The dispenser will then pump out soft, fine foam , saving you 3-5 times the soap cost compared to using a liquid dispenser.
Q: Why are foam soap dispensers more popular than liquid soap dispensers?
A: Besides saving detergent, the fine foam spreads better, cleaning evenly between hands, and most importantly, it's easier to rinse off , saving water and reducing hand-washing time. It's ideal for office buildings and public restrooms.
Q: Does it dispense a large amount of foam per use?
A: The machine dispenses the right amount of foam, about 0.8 ml per use , which is sufficient for one hand wash. It's not too much to make a mess, and not too little to be ineffective. This helps to accurately control the monthly cost of hand sanitizer.
Q: What is the tank capacity, and is it difficult to refill?
A: The tank has a capacity of up to 1,000 - 1,200 ml (depending on the model), supporting long-term use. For refilling , we recommend "removing the tank" to refill it outside the device. This is to prevent accidents from spilling liquid and leaking it into the internal mainboard, which is a major cause of potential damage to the device.
Q: What size batteries does it use, and how long does it last?
A: Use 4 size C alkaline batteries. These have a higher capacity than regular AA batteries, allowing for an average usage of 1 year or more than 30,000-50,000 uses. No more worrying about frequently changing batteries.
Q: What should I do if the pump head is clogged or no foam is coming out?
A: This problem is usually caused by mixing the soap "too thick." The solution is:
1. Pour out the old solution.
2. Fill with warm water and start the machine to flush the pump head.
3. Mix a new soap solution, diluting it (a higher water ratio is recommended), and the machine should work normally again.
Automatic Fragrance Dispensers & Air Fresheners
Q: How is the LCD model (HAD-001) better than the standard on/off switch model?
A: It is much better in terms of chemical/liquid saving, because the LCD display model allows you to set the actual operating schedule (for example, operating only Monday–Friday, 08:00–17:00).
This prevents the unit from spraying unnecessarily during nights or holidays when no one is present, effectively doubling the lifespan of the fragrance refill.
Q: Can the spraying frequency be adjusted?
A: It's very precise. You can set the spray interval from 1 minute to 60 minutes as needed (unlike typical models that are usually locked at only 5/10/15 minutes), allowing you to accurately control the fragrance to suit the size of the room.
Q: Do I have to use only Hygienic brand fragrances, or can I use other brands?
A: Our machine is designed to accommodate standard 300 ml refillable cans (short cans), which can be purchased at most supermarkets.
• However, we recommend: Hygienic's premium-grade fragrances (such as Country Escape) because their spray nozzles are designed to disperse the scent further and last longer.
Q: What size batteries do they use, and how long do they last?
A: It uses 2 D-size batteries (large batteries), which provide more stable power than AA batteries.
This ensures consistent motor performance for the spray mechanism and allows operation for 6–12 months without frequent battery replacement.
Q: How high from the floor should I install it to make the fragrance fill the whole room?
A: We recommend installing it approximately 2 meters or more above the floor. This allows the fragrance mist to disperse from above and cover the widest area (approximately 20-30 square meters). Avoid installing it directly above a ventilation fan to prevent the scent from being immediately drawn out.
Insect Killer
Q: What are the differences between "Zapper" and "Glue Board" types? Which one is better?
A: It depends on the area of use.
• Electric shock type: Uses electricity to shock insects into a tray. Suitable for general areas, hallways, or garbage disposal areas (advantage: no need to buy replacement adhesive pads).
• Adhesive type: Uses UV light to attract insects to stick to a glue sheet . It's silent and doesn't scatter insect fragments, making it the only type that meets GMP/HACCP standards for food processing plants and restaurant kitchens.
Q: Why are electric insect traps prohibited in food factories?
A: Because electric zapping causes insects to shatter and scatter, potentially dispersing fragments outside the unit. This creates a risk of food contamination.
Therefore, food production or packaging areas must use glue board (adhesive trap) models only, which securely trap insects in place and allow for safe, hygienic disposal.
Q: Where is the best place to install this insect trap for optimal effectiveness?
A: The best location is a "dark and sheltered spot" near an entrance/exit (but don't point the device towards the door, as this will attract flies). It should be installed approximately 1.8 - 2.5 meters above the ground, which is the flight level of flies.
• Caution: Do not install directly above the food preparation area to prevent accidents.
Q: What is the best time to turn on the device?
A: It should be on 24 hours a day because some insects are nocturnal, and to allow the UV light to work at its full potential in attracting insects, contrasting with natural light.
Q: How often do I need to replace the adhesive pads?
A: We recommend checking monthly. If the sheet is completely covered in insects or has a lot of dust accumulation (making the adhesive lose its stickiness), replace it immediately. Typically, the lifespan of the adhesive sheet is 1-3 months , depending on the amount of insects in the area.
Q: The light bulb is still working, why do I need to replace it?
A: Insect trap bulbs have a "UV-A light" lifespan of approximately 1 year (8,000 - 10,000 hours). Even though the light may still appear to be on, the UV light that is visible to insects will degrade to the point where it no longer effectively attracts them. Therefore, it is necessary to replace the bulb annually.
Alcohol
Q: Should I choose "liquid" or "gel" type? What are the differences?
A: You need to choose based on the type of dispenser you are using.
• Liquid alcohol: Clear and liquid like water, suitable only for spray bottles . Dries quickly and leaves no sticky residue.
• Alcohol gel: A clear, viscous gel, suitable only for pump bottles or dropper dispensers.
• Warning: Do not put the gel into a spray dispenser, as it will immediately clog the nozzle.
Q: What is the difference between 70% and 75% alcohol? Which one is better at killing germs?
A: Both are capable of disinfecting against germs and viruses according to public health standards.
• 75% v/v (Hygienic Standard): Ideal for hand washing, evaporates at the perfect rate for full germ-killing effectiveness before drying.
• 70%: Often used for wiping and cleaning surfaces or medical equipment (Pharma Grade).
Q: What is the difference between "Food Grade" and "Pharma Grade" products?
A: Both are high-safety grade products, but they have different strengths:
• Food Grade: Made from natural ingredients (such as molasses). The key feature is that it's "safe if ingested," making it ideal for restaurants or homes with young children who might accidentally handle and eat food immediately after washing their hands.
• Pharma Grade: This is a high-purity grade that meets "pharmaceutical manufacturing standards" (USP/BP Standard), ensuring cleanliness and freedom from harmful impurities. It's suitable for use in hospitals and laboratories. (This quality is significantly higher than typical grades found on the market.)
Q: Does it cause dry, peeling hands?
A: The Hygienic 75% formula contains skin -friendly moisturizers . It dries quickly but doesn't leave hands feeling rough or dry, even with frequent washing throughout the day; they remain soft.
Q: How many times can a 3.8-liter gallon be refilled into the dispenser?
A: It's very cost-effective. A 3.8-liter gallon can fill an automatic dispenser (1-liter capacity) almost four times completely, or that translates to over 4,000 spray uses per gallon.
