In the hand dryer section of the FAQ, one can get an overall picture of not only how the technical spec data is calculated but also about the making of hand dryers. This section also addresses the difference between the conventional hand dryers and the high speed hand dryers, which is one of the questions that are most frequently asked by people who are new to the product categories of hand dryers.

In addition, as hand dryers are installed in public washrooms such as those in schools, hospital, shopping malls, sports stadiums, and hotels, the explanation of related requirements such as ADA compliance, the ERP directive and the IP ratings are also included in this section.
Moreover, Hokwang understands that being “green” is extremely important for buildings and owners nowadays, thus, the LEED credits and power consumption issues are also discussed. Of course, if further information is needed, please do not hesitate to contact us by filling in the form on the Contact Us page. Thank you.

High Speed hand dryers can help projects qualify for LEED (Leadership in Energy and Environmental Design) credits. Instead of using paper towels, Meeting LEED requirements below; 1. Reducing energy consumption with fast dry times 2. Reducing the waste, 3. Improve operational costHokwang high speed hand dryers may obtain the below LEED CREDITS (LEEDv4 Rating Systems).LEED v4 for Building Design and Construction (BD+C) -EA (Energy and Atmosphere) Prerequisite: Minimum Energy Performance -EA (Energy and Atmosphere) Credit: Optimize Energy Performance -MR (Materials and Resources) Credit: Building Product Disclosure and Optimization – Environmental Product Declaration -MR(Materials and Resources) Credit: Building Product Disclosure and Optimization – Sourcing of Raw Materials -EQ (Indoor Environmental Quality) Credit Green CleaningLEED v4 for Building Operations & Maintenance (O+M) -EA (Energy and Atmosphere) Prerequisite: Minimum Energy Performance -EA (Energy and Atmosphere) Credit: Optimize Energy Performance -MR (Materials and Resources) Credit: Facility Maintenance and Renovation Read More
The blue light is an indication light to guide users to the most efficient drying area. Hokwang is the first manufacturer that uses this identity.It brings some fun to the hand drying process and some kids could really enjoy playing with the blue light. It also creates a sense of modernness and high technology. Read More
A conventional hand dryer dries hands by warm air. The air speed is relatively low and so does the noise level. A high speed hand dryer dries hands by air speed. It literally blows water away. It uses less power as it focus on air speed rather than air temperature (heating element). For an example of conventional hand dryer, please refer to HK-2400 hand dryer. For an example of high speed hand dryer, please refer to HK-JA or EcoMo hand dryer. Read More
There are CE, LVD, EMC, EMI, GS, CB for Europe, UL, cUL, CAS for north America, SAA for Australia, CCC for China, etc. All electrical appliance, including hand dryer, should pass safety approvals and use qualified materials. Some countries have special requirements for safe tests, you can always contact your supplier for further information or assistance. Read More
There are different ways of measuring “green profiles” for a hand dryer. One is from the energy consumption. Conventional hand dryers usually cost more energy due to the high wattage and longer drying time. Hence, a high speed hand dryer are often considered energy-saving hand dryer, for its fast-drying feature and low power consumption. Institutions and regulations, including GreenSpec, PCR (Product Category Rule for hand dryer issued by UL Environment), ETL (ETL Method for the Testing of High Speed Hand Air Dryers) all set standards for this measurement.Another way is to measure how many recyclable or non-toxic materials are used to assemble a hand dryer. For example. RoHS and WEEE are two certifications that verifies this measurement.The third one is a trend in recent years: the verification of product carbon foot print. It usually calculate not only the emission of carbon dioxide when using an electric appliance, also the accumulation of carbon dioxide during the whole manufacturing and transportation process.

European Commission Regulation No. 1275/2008 came into force regulating requirements for standby and off mode electric power consumption of electrical and electronic household and office equipment. This regulation arises from the One Watt Initiative by the International Energy Agency (IEA). The regulations mandate "off mode" and standby power shall not exceed 0.5W. Equipment must where appropriate provide off mode and/or standby mode when the equipment is connected to the mains power source. Read More
IP code (International Protection Marking) classifies and rates the degree of protection provided against intrusion and water. The first digit indicates the level of protection that the enclosure provides against access to hazardous parts. The second digit indicates the level of protection that the enclosure provides against harmful ingress of water. It depends on the installation site to decide the necessary IP rating for the hand dryer. It is not a sole assessment to a hand dryer as there’re other criteria for a safe hand dryer Read More

There’s no definite answer to this questions. You can find many casing materials, such as high impact plastic, stainless steel, steel with coating, aluminum, etc. The selection of casing materials usually depends on the installation location. You may want to use a stainless steel casing if your wash basin it made of the same material. If you have a white or ivory interior design, you may want to choose a white coating to keep it in the same color tone. It makes your purchase easier if you can find all of them from one supplier.

It’s an abbreviation for Americans with Disabilities Act. It defines the accessible requirements for the design and construction of washroom space in the United states. EDF (European Disability Forum) in Europe shares similar ideas of promoting disability rights. 1. a hand dryer shall protrudes no more than 4 in (100 m) into walks, halls, corridors, passageways, or aisles. 2. for installation, the maximum mounting high forward reach allowed shall be 48 in (1220 mm). The minimum for low forward reach is 15 in (380 m). Read More
There’re two common types for hand dryer filters: carbon filter and HEPA filter. These are usually installed in the air inlet of a hand dryer, some of them can be inserted inside of a hand dryer. A carbon filter can filter dust, lint, etc., and thus lengthen the life cycle of a hand dryer. A HEPA filter (often comes in an assembly) can filter different ratio of airborne particles according to the HEPA class. Currently EcoMo (equipped), HK-JA (optional) have HEPA filter (class H13 with retention >99.95% in total). Other models in high speed hand dryer range have carbon filter as an optional accessory.

Total watt/1000 x drying time (seconds)/60/60=____kw/hr Take EcoFast high speed hand dryer for example. It’s 1000W/1000x10 seconds/60/60=0.0027 kw/hr. Read More
Installing a hand dryer can be cost-saving in the long run, especially for public washrooms. It also helps hand hygiene and avoiding the spread of bacteria and other germs. Generally, you can choose from the casing design, the color or the preferred operation way (manual or automatic). Sometimes the mounting option or the power consumption also matter when you’re trying to apply for a green building or a user-friendly washroom design. Read More
