The third part of this three-part article highlights the rise of jet-air hand dryers.Today, more facilities are installing jet-air hand dryers that rely on high-velocity air rather than just heat to speed up the drying process.“Jet-air dryers have taken over the market,” says Bruce Heller, president of Cavalier Inc. “I don’t think it’s the norm anymore to get traditional heated air dryers.”Jet-air hand dryers can dry hands in approximately 10 to 15 seconds — about half the time it takes to dry hands with a heated-air hand dryer.Although most jet-air dryers use unheated air, some models offer heated air as a comfort consideration. However, NSF International, formerly the National Sanitation Foundation, Ann Arbor, Michigan, recommends that facilities install dryers without heating elements, because heat strips essential oils from the skin, which can create micro tears and cracks in the skin that harbor infection. Granite Telecommunications in Boston switched from heated jet-air hand dryers to non-heated jet-air hand dryers, because employees were complaining that the heated air dried out their skin.“We have two 250,000-square-foot buildings and 1,500 employees that go through these restrooms,” says Facility Manager George Meegan. “Originally we had some dryers with heat and some without, but most of the employees preferred them without heat. So we started replacing the dryers with non-heated ones.” To date, Granite Telecommunications has replaced approximately 20 heated dryers with non-heated units in its restrooms and is still in the process of converting the remainder.Meegan says the velocity of the air in the new dryers is so fast that it feels as if it’s heated. “When we tested the new dryers, you couldn’t tell the difference,” he says. “The air feels like it’s heated, and the dry times are about the same as the previous model.”Dowling of SupplyWorks, Meegan’s distributor, admits that traditional heated-air hand dryers are less common today, due to the advent of jet-air dryers. “Heat has never been a requirement for properly drying hands,” he says. “It’s a comfort thing. With high-pressure hand dryers, it’s not necessary to have heat nowadays.”Regardless of whether customers opt for heated, non-heated or jet-air hand dryers, end users sometimes grow impatient with the length of time it takes to dry their hands and therefore don’t dry their hands completely, or they wipe them on their clothing as they exit the restroom. Neither option is sanitary.“People get tired of standing there, and sometimes there aren’t enough dryers, so they’re standing in a line, dripping water on the floor,” says Hicks. “The public expectation is the same whether it’s an airport or a stadium: It shouldn’t take long [to dry hands with a hand dryer], and when I’m done, my hands should be dry.”Facilities managers should, therefore, opt for whatever type of hand dryer — heated, non-heated, jet air — that patrons in that facility most prefer, since a hand dryer only aids in hand hygiene if it is used and used correctly. As a result, distributors will need to carry a few different models to guarantee the sale. Kassandra Kania is a freelance writer based in Charlotte, North Carolina.
