Pulsed air hand dryer, hygiene and economy
When buying a high-velocity hand dryer, you should first check whether it has a HEPA filter . This type of filtration eliminates up to 99.997% of bacteria .
Some hand dryers lack a water collection tray (for the water produced during drying), and as a result, the water drips directly onto the floor. This leads to tedious cleaning and, more importantly, an unsightly state of the restrooms.
A high-pressure air hand dryer is also characterized by its IP rating and insulation . There are Class I devices that require grounding and Class II devices that do not.
On the other hand, there is one common point which can be annoying in certain cramped spaces, which is the noise level.
It is certain that compared to a classic model and even more so to a paper towel dispenser, this will not be the strong point of a pulsed air device.
The different types of pulsed air hand dryers
The most widespread model and which historically made the success of forced air models and the so-called "vertical" model.
However, since then, designs and developments have been validated to perfectly adapt the model to the premises and/or use.
So there are now compact models to overcome space problems , and models with limited power to prioritize silence.
Indeed, the main drawback of vertical models , which make up a large portion of the current market offering, is their sometimes unsuitable size for the room. Furthermore, this type of model can be completely unsuitable for people with reduced mobility or for children, for whom inserting their hands is too high and therefore impossible.
Vertical pulsed air hand dryer
When choosing from the various models of high-speed hand dryers, the simplest approach is to opt for solutions that have proven themselves over many years without compromising on quality. This is the case with a vertical, wall-mounted hand dryer. These generally feature an infrared sensor for touchless operation. Easy to install and blending into many environments thanks to its understated design, the vertical high-speed hand dryer is a reliable choice for this type of equipment. It also benefits from a more affordable price than other alternatives. These devices are guaranteed for between 2 and 5 years, depending on the manufacturer. The electronic circuit board is often the first component to fail on this type of appliance, so it's important to ensure the device is supported over time.
Hand dryer with pulsed air and HEPA filter
High-pressure hand dryers with HEPA filters (High-Efficiency Particulate Air filters) are ideal for combating bacterial growth. These filters retain up to 99.97% of airborne particles with a diameter of 3 µm or larger.
Hand dryers using this type of system allow for the circulation of clean air in the rooms where they are installed. Therefore, high-pressure hand dryers with a HEPA filter are particularly recommended in certain environments, including:
• Health establishments
• Residences of people vulnerable to air pollution
• Areas dedicated to IT or microelectronics
• Educational establishments, such as colleges, schools, high schools.
However, it should be noted that in the objective context of a search for a drying solution providing the maximum guarantees from a bacterial contamination point of view , paper hand towels remain the reference.
Compact and stylish hand dryer
When choosing a high-speed hand dryer, it's essential to consider where it will be installed . In a stylish and elegant setting, a high-quality hand dryer is highly desirable. This is the reason why compact and stylish hand dryers, such as the Exp'Air and Stell'Air JVD, Airsmile, or Zeff models from Rossignol, were created . Not only do they offer exceptional efficiency, but they also boast an innovative design that blends seamlessly into your interior décor.
These models, such as the Exp'Air or AirSmile, have the advantage of being PMR compliant and accessible to children and people of small stature.
Maintenance and care of pulsed air hand dryers
Maintaining a high-speed hand dryer is important for several reasons. Regular maintenance ensures hygiene, performance, and extends the equipment's lifespan. Several steps must be followed for this purpose:
• First unplug the device;
• Thoroughly clean several parts of the pulsed air hand dryer, including:
o Ventilation grilles: dirt must be removed using a soft brush;
o The outer casing, using a soft cloth dampened with a non-abrasive cleaning product.
o Finally, HEPA filters on eligible models. Filters must be replaced regularly to ensure the proper operation of the affected jet air hand dryers.
• Remember to regularly empty the water collection tray for the maintenance and upkeep of a pulsed air hand dryer that has one.
Depending on the specific model of the high-speed hand dryer, additional precautions may be necessary for equipment maintenance. It is therefore important to read the user manual provided with the dryer to ensure good hygiene in professional settings.
What are the advantages of jet air hand dryers?
High-speed hand dryers, also known as forced-air hand dryers, use a powerful airflow to quickly dry hands after washing . Here are some of the advantages of these devices:
Quick drying
One of the main advantages of high-speed hand dryers is their ability to dry hands in just seconds. Thanks to the power of the airflow, water is quickly removed from the hands, leaving them feeling dry and clean. Compared to manual hand dryers or disposable paper towels, high-speed hand dryers offer faster and more convenient drying.
Energy saving
High-speed hand dryers are also known for their energy efficiency. Unlike disposable paper towels, which require constant production, high-speed hand dryers use only electricity to operate. Furthermore, many models are equipped with motion sensors that allow the hand dryer to activate only when hands are present , thus reducing energy consumption.
Improved hygiene
Hygiene is a major concern in restrooms, and high-speed hand dryers can help improve these conditions. Unlike paper towels, which can be a potential source of contamination, high-speed hand dryers eliminate the need for physical contact with potentially dirty surfaces . Furthermore, some models are equipped with HEPA-type antibacterial filters that remove particles and bacteria from the air, ensuring more hygienic drying .
Reduced environmental impact
High-speed hand dryers are considered a more environmentally friendly option than paper towels. By eliminating the need for the constant production of paper towels, high-speed hand dryers help reduce the amount of waste generated. Furthermore, some models are made from recyclable materials, which helps to minimize their environmental impact.
