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.

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.
