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 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.

When setting up a washroom, you have lots of choices when it relates to the kind of hand drying technique to deliver. Public washrooms which are busy all the time should have fast and effective hand drying features so that the people can clean and dry their hands without standing in a line. If somebody has waited in line already in a workplace, they really wouldn't like to wait once again just to dry their hands.

Nevertheless, you will find more options to consider than the pace of the hand drying system. The appropriate way of hand drying is important to hand hygiene and avoiding the spread of bacteria and other germs, so the hand dryers has to be effective and hygienic.

So, which hand dryer you need to select for your office area? Here's an explanation of some of the most recent modern hand drying products to consider.

Mounting option
One of the aspects that you have to consider when purchasing an electric dryer is how it's mounted on wall surfaces and how it'll adjust. The weight and size of this electric dryer will identify what kind of installation you require for hanging it on the wall. Some dryers need a kit to attach them effectively on the wall. Some of these require being seated on the counter to get balance. Some others are small enough to be installed on whatever surface area is readily available.

If you have a small washroom space, you should consider a deck-mounted hand dryer, which can be combined with the wash basin. You can also choose a compact size, such as the EcoSwift or EcoSlender high speed hand dryer. If you have enough room and you search for elegant design, the wall-mounted high speed hand dryer, such as HK-JA01 or EcoMo can surely satisfy your requirements.

Power Consumption
“Green” has become the priority when manufacturers design new products. Compared to conventional dryers, high speed hand dryer dries hands by blowing water away with its powerful air speed. Most of the high speed hand dryer can turn the heating element off to further decrease the power consumption. All of Hokwang’s high speed hand dryer has power consumption no more than 1.6kW. Some units like EcoSwift and EcoFast can be as low as 500W while dry hands within 12 seconds.
No matter you are trying to replace your current dryer/paper towel dispenser with a new one, or rebuild your washroom, the green and fast high speed hand dryer is undoubtedly the best choice.

Auto or Manual
Some hand dryers run in an automatic process. These hand dryers utilize a motion sensor for being turned on or off. There are press button models as well a button type. These push button models can be performed at a preset time and the preset time can be modified. It is more common to use an automatic type, as users do not have to touch the button which can further prevent the spread of disease. Nevertheless, some places still use a manual type as a hair/face dryer.

It is suggested to use an auto hand dryer, especially a high speed one, wherever you want to install a hand dryer. If you have special requirement to use a hand dryer as hair/face dryer, a manual type is still available in the market, such as our HK-2400 conventional dryer.

Durability of hand dryer casing
The durability and toughness of the hand dryers are identified by the material applied to produce the product. Hand dryers might be produced utilizing cast aluminum, steel, stainless steel, solid iron and some other materials. After you examine the durability of hand dryer, make sure to look at the warranty as well. It's best to compare the warranty provided by various companies.

A qualified hand dryer should be approved by international safety approvals. Some cheap dryers use low quality plastic cover and materials, and this can lead to a bad smell of burning plastic. A high-impact and fire-proved plastic is highly suggested not only for the durability but also for the safety. There’re other options for metal casings. In general, a good quality of stainless steel such as stainless steel #304 can avoid cover from rusting. Also, a metal casing is durable and able to withstand a certain degree of impact. However, if someone use hammer to hit the cover, it is unlikely to keep intact. There’s still an option for an enamel coating casing, which is rare in the market due to the difficulty of making it. Our HK-JA01 still has the enamel coating casing and it is the most durable casing finishing in the market.

Final Thought
The above features are a few things that'll help you select the best hand dryers available in the market. Some dryers stand out more than other dryers so it's a wise decision to compare between a couple of dryers before you purchase. Just remember to choose the hand dryers that have complete safety approvals and a manufacturer with quality certification.
