The quickest hand dryers in the world will dry the hands in around 10-15 seconds, although anything under 20 seconds will not disappoint. In our experience, although you may see it advertised elsewhere, there is no hand dryer that can dry the hands to a satisfactory level in under 10 seconds. The main benefits of a fast dry hand dryer are:
There is a trade-off between noise level and dry time, with quieter hand dryers tending to have a slightly slower motor speed to the quickest drying. That said, hand dryers have come a long way since the very low noise models that take over 40 seconds to dry the hands and are very energy-hungry as they rely on a heater element to try and evaporate water off the hands rather than scraping it off. Mitsubishi Jet Towel hand dryers are some of the best for balancing rapid dry times with reasonable noise levels and this is one of many reasons these reliable units are chosen as hand dryers for many schools and universities.
Quiet yet good performing hand dryers like the Dyson Airblade V or the Dryflow Viper HEPA hand dryer, have been awarded the Quiet Mark accreditation. This award is passed by products that are not only easy on the ear but actually do the job they were intended to do well; in this case, actually dry the hands.
An adjustable hand dryer may be a good option for you. These allow for motor speeds to be manually adjusted, either by a high/low switch or a dial. These are great for buildings that require the same looking hand dryer throughout a building but some of the areas of the location are noise sensitive. They give you the option to adjust accordingly. Some of the hand dryers that allow this are the Dryflow G-Force MKII, Mitsubishi Jet Towel hand dryers, Turboforce hand dryer, Jet Force Junior HEPA hand dryer and Dryflow Viper.
If getting customers in and out of the washroom quickly is important, or indeed you are looking to reduce wet floors, then you may wish to consider a hand dryer that can fit directly over the sink like a tap. This style was made popular when the Dyson Tap was launched, which is a water tap and dryer in one unit. There are now a number of great alternatives to the Dyson Tap hand dryer, that not only match the performance but come with the flexibility of having each component of the series as a separate unit. This brings the advantages of taking just the hand dryer, or indeed having all the facilities of handwashing available, should you choose. Two great units include the Dryflow Bi-Tap and Dryflow Tri-Tap series.
