Selecting the Ideal Hand Dryer for a Commercial Bathroom

Like most hospitality business owners and entrepreneurs, you might not think much about the humble automatic hand dryer. As long as it looks nice and blows fine, every model is OK, right? Well, this is not entirely true, as there are several features the ideal commercial bathroom hand drier has to feature.

What’s the airflow temperature?

The speed of airflow in a hand dryer can reach up to 250 meters per second but the temperature of this airflow is equally important. On average, the air blade can heat up to 80° Centigrade, while the lowest operating temperature is set at 40° Centigrade.
Once you combine the speed with the airflow temperature, you get the optimal parameters for the blade of air to dry human skin within seconds. Therefore, look for this ratio in the manufacturer’s instructions to discover how efficient a particular model is.

How hand dryers are classified

Another criterion to select the right hand dryer is the power of the heater. In fact, hand dryers are classified according to heater power, as there are 3 general categories. Low power dryers are appliances of up to 1 kW in power, meaning that it will take longer to dry one’s hands but the power usage will be negligible (ideal for bringing down electricity bills).
Medium power dryers are twice as strong and the blowing force is significant. Of course, the size of the nozzle will influence drying times for most medium-power models (which are the most common in the market). Finally, there are high power hand dryers that deliver a huge blow, pun intended, and dry up hands in seconds. These devices feature heaters over 2 kW of power.

The secret of the nozzle

Having listed all the power categories of hand dryers, we should add that the nozzle has an impact on the overall power output. Namely, the size and the general shape of a nozzle affect airflow in several ways. Wide nozzles slow down airflow and reduce the heating power, while narrow nozzles can turn a low-power hand dryer into a beast.
When choosing the nozzles, select the ones that meet the needs of people who are going to use them. For instance, there is no point in installing a wide nozzle on a dryer that is going to hang in a kindergarten bathroom. A narrower nozzle is far more suitable for small children’s hands.

The silence of the fans

Since a fan is the heart and soul of every dryer, these appliances can be quite loud. In general, the more powerful the dryer, the louder it is. However, a commercial hand dryer used in medical facilities should have built-in devices to suppress noise and vibration.
Apart from hospitals, restaurants, cafes, and schools can also benefit from silent hand dryers. Otherwise, they’ll need to soundproof the restroom. Basically, manufacturers “silence” a dryer by reducing the speed of the fan, buffering the vibration it generates while rotating.

Models with air filtration

Hand dryers are all about blowing air around but have you ever stopped to wonder about the quality of the air circulated? In older models, the air is unfiltered but modern electric models come with air filtration.
This feature is necessary to prevent bacteria from accumulating inside the device and then getting blown onto the hands of unsuspecting patients or customers. Air filtration does raise the price of hand dryers slightly but you can’t put a price on cleanliness.

Durable and less durable materials

Hand dryers are made from various materials; plastic and metal being the most common dryer types. The former are the economical kind, as they aren’t resistant to blows from careless users. Dryers made from polypropylene are definitely the budget option and they are ideal for bathrooms with a limited number of users.
On the other side, you will have a hard time accidentally putting a dent into a chromed hand dryer. The enamel-coated metal offers excellent protection against mechanical damage, although users can inadvertently scratch them. Such hand dryers are common in schools, discos, and bars, i.e. places where the restrooms are most often vandalized.

Turning on the hand dryer

Regardless of the material it is made from, users often fiddle with a hand dryer’s inclusion type. Namely, mechanical dryers are turned by pushing a button, while automatic ones are activated through a sensor. The former are older models that aren’t very hygienic since you have to touch a button to turn them on.
However, a mechanical dryer seldom heats up. Automatic dryers switch on automatically sing an infrared motion sensor, making them 100% sanitary. Such a practical design is ideal for every setting, from hospitals to shopping malls.
The modern commercial bathroom can hardly be imagined without an automatic hand dryer. There are various models to choose from but you shouldn’t have money on older, less hygienic models. Contactless operation, powerful heaters, and silent dryers will set high sanitary standards in your commercial restroom. With all the viruses lurking in the air, hygiene at work is important now more than ever!
