Certainly, you often find yourself using this when you are in a comfort room in the mall, at school, or at the airport. If you are curious about what happens inside those fascinating devices, and how it works to swiftly dry your hands, you are in the right place. Learn the five steps on the hand dryer working principle, touching on the following pointers:

• Air intake
• Air filtration
• Heating (or cooling) element
• Blowing air
• Drying process

Let’s get to the discussion, but first, here’s a review of what commercial hand dryers are:

What Are Commercial Hand Dryers?

It’s not common for average households to have hand dryers, so these devices are most likely intended for commercial purposes. The commercial types are designed to provide for high-traffic places, such as public restrooms, businesses, and offices, built to cater to a large group of people, unlike the standard in-home dryers.

The best ones have features, such as quick airflow, robust construction, and hygienic design, all of which are paramount for them to work efficiently. So, how do hand dryers work really?

The Hand Dryer Working Principle

You can be able to understand the working principle of your commercial hand dryers in five steps.

Step 1: Air Intake

Generally, commercial hand dryers are equipped with intake vents to draw in ambient air from the external surroundings. However, some units feature flow-directing frames with arched profiles to block the shearing of airflow and avoid noise.

Meanwhile, some may focus on air intake locations to reuse heated air and thereby, save energy. Concerning the air intake structure, this improves efficiency, especially in high-pressure units, and could be located proximate to motor blades.

Step 2: Air Filtration

A process regarded as recent because of the new features in hand dryers, that is, air filtration, such as what you can see from Interhasa’s devices, air filtration is possible with the HEPA or filters of particulate air in high-efficiency, treating the incoming air.

This filter traps almost 100 percent of bacteria in the air, as well as other contaminants, guaranteeing that the air flowing onto your hands is safe and clean. Some hand dryers may also use UV light working with the filters to break down harmful microorganisms.

Step 3: Heating Element

The best-performing hand dryers for commercial use tap their heating element to warm the air before it gets blown onto the person’s hands, like how water dispensers or vapes work. This element converts electrical energy to heat energy using wired coils or ceramic elements, among others.

Step 4: Blowing Air

To create a powerful airflow, the dryer’s motor powers the blower. The minute the sensor detects hands, this motor gets triggered, spinning the fan and drawing in air. As the dryer directs this air, either heated or cool air through the nozzles, the air is blown out, drying the water or moisture from the user’s hands.

Step 5: Drying Process

A commercial hand dryer cannot drive home its point and purpose for the user without this process. Here, the airflow generated – whether heated, high-speed, or a combination – is directed onto the person’s hands to remove water and moisture.

Heated air promotes evaporation, while high-speed jets use a powerful flow of unheated air, termed “blasts,” to blast the water off the user’s hands. Thus, leaving them dry, since walking with wet hands in a public space can spread germs more easily.

How long does it take for those hand dryers to work? You can finish drying off your hands in within 10 seconds with the best hand dryers.
