You are tied to the dispenser to dry your hands - a
problem in busy periods.
Hot Air Machines have a high initial capital cost,
and require a specific power source controlled from
outside the washroom area. They do break down or
blow cold air. To dry your face is not a pleasant
experience. Many reports cause for concern the
hygiene aspects of this system. Not all germs are
eradicated by the hot air, some are dispersed into
the atmosphere. Look below a hot air machine at the
discolouration of the surface. Again the queuing
factor comes into play.
