What is the hand dryer?
The hand dryer is an electronic device that uses mechanical air blowers – which can be heated or not – to dry your hands, eliminating the need for towels or paper.
Widely used in public restrooms such as airports, shopping malls, universities, offices, etc., hand dryers can differ greatly from one model to the next.
Some models, usually the older ones, are activated by means of buttons or levers. More modern versions have motion or infrared sensors, which activate the dryer without the user having to touch it, just as the appliance approaches.
How did the hand dryer come about?
The first patent for a hand dryer was registered in 1921 by RB Hibbard, DJ Watrous and JG Bassett for the Airdry Corporation of Groton New York. This precursor model consisted of an inverted blower, much like a hairdryer, and was operated by means of a pedal.
The product has grown in popularity around the world since then, especially since 1993, when the Mitsubishi Electric brand created a new type of U-shaped hand dryer.
Innovative, the model now reproduced by many brands emits puffs from both sides, focusing on pushing water out of the hands instead of drying it.
Is the hand dryer worth it?
The use of the hand dryer is more common at the commercial level, in public bathrooms and with a lot of movement. In this scenario, the product proves to be very efficient, since it promotes a reduction in operating expenses with energy and consumption of paper towels.
The device also contributes to the cleaning and organization of the environment, since it eliminates the accumulation of paper in the dumps and the constant need to empty them. Research indicates that the dryer is also more sustainable than paper, even using electricity.
According to data from the dryer manufacturer World Dryer, in its useful life – which is an average of 10 years – the dryer emits 3 tons of CO2 less than the production of paper towels, considering the proportional uses of the two options.
Which is the best: Manual or sensor hand dryer?
The ideal hand dryer for the bathroom is one that besides being functional and practical, is easy to maintain and hygienic. To avoid problems with contamination, choose washable and alcohol-resistant models or sanitizing products.
Some older models of dryers have caused great controversy after research found that the devices spread particles of faecal coliforms and other bacteria present in the bathroom. To escape this risk, prefer models equipped with filters or that use rays or UV light to kill germs in the environment.
It is also important that the chosen dryer requires minimal physical contact with the user for its operation.
Models with a motion sensor are the best option as they are practical and hygienic, eliminating the contact of the user’s hands with any part of the device at the time of use.
Hand dryers can be found for prices that vary greatly according to the make and model. It is possible to buy the simplest models from R $ 300. The more sophisticated models, with motion sensors and sterilizing or bactericidal action can cost more than R $ 1,000.
Where to buy?
You can buy your hand dryer in specialized stores or with products for decoration and construction for example.
However, it is on online platforms Amazon. that you can find the greatest diversity of brands and models of the product.

So that there are no doubts at the time of purchase, we will detail each topic below. Check out:
The power of the hand dryer can be defined by the ratio between the speed and the air flow generated by the device, which will directly influence the drying time of the equipment.
It is important that the chosen dryer is efficient and fast, as, in general, people do not have much patience to use the appliance for more than 15 seconds.
The stronger the air generated by the dryer, and the greater the flow provided by the model, the faster the drying of the user’s hands will be, therefore, the more powerful the dryer is considered.
The energy consumption of the hand dryer will vary according to the model and its power. Most dryers use, on average, 2,200 watts of power when turned on, and 2 watts when they are in stand by .
When drying your hands for 30 seconds, 0.018 kWh of electricity will be consumed. Doing this three times a day for a year will consume 19.71 kWh, which accounts for 12 kg of carbon dioxide emissions.
The mechanisms used by dryers to generate air and / or heat vary according to the model and brand of the product. Some dryers generate air through a fan, others through mechanisms similar to the hair dryer, while others use motors.
More powerful and professional models use turbines. The heating mechanism is not present in all dryer models. But, when used, it consists of an electrical resistance coupled to the blower, which can be formed by wires of nickel or chromium alloy in a spiral shape, which when heated generate the heat transferred to the dryer air.
Hand dryers are generally activated for operation from an activation button or lever or from a motion sensor. The most common type of sensor in these devices is the infrared.
Sensor-activated products can have an added value when compared to manual activation, but they are considered more hygienic, since people do not need to touch the device to put it into operation.
