The Choice of Different Hand Dryers
Other choices such as paper towel and roller towel dispensers need to be replenished often, which can be quite an expense over time for busy restrooms. Automatic hand dryers are by far the most hygienic option in comparison to towel dispensers, with infrared motion sensors detecting hand movement under the nozzle.
Push button dryers are cheaper and can be fitted more easily, though need to be cleaned more regularly than automatic dryers, to ensure hygiene. A cast-iron dryer with an enamel coating is the easiest to sanitize, though the enamel will need to be sanded away if you want to paint it.
Cast iron is the best material for dryers in the public space, with high strength and longevity. The standard fixed-nozzle hand dryer is cheap and reliable, perfect for small companies who want good restroom hygiene.
Other models offer rotating nozzles for drying the face, though these are often not needed for small restrooms in a general office space. With a larger budget and more operational considerations, the drying time stated by the manufacturer is one of the most important metrics for convenience, especially if your restroom is busy.
Cheaper models will have a drying time of around 40 seconds, whereas accelerated dryers can dry in roughly 15 seconds. The most expensive options - such as blade dryers - offer superior drying-times and excellent levels of hygiene.
Noise levels are the final consideration, with manufacturers giving dryer loudness in decibels. 70 decibels is common for basic models, though if your commercial space demands quietness then you should look for around the 50 decibel mark.
