Air Shower


Decontamination equipment by high-speed air injection is commonly referred to as “air showers.”

Air showers are enclosures specially designed and designed for the removal of particles from people or materials, prior to their access or exit from certain clean areas. They allow the cleaning of the particles that remain deposited in the user’s clothing or materials, and are used mainly in the income to clean areas with high classification requirements, such as sterile areas, and exits of areas in containment.

They are cabins that are specially prepared to remove dust particles and polluting products that may be deposited in personnel’s work materials or clothing at the entrance or exit of clean or containment areas.

Air Showers Functioning:

Its principle of operation is the impulsion of jets of ultra-filtered air at high speed (> 35 m / s) on the person or material to be cleaned to produce the separation of the particles deposited on its surface.

The air is propelled by columns of horizontally driven aerodynamic nozzles located along the four angles of the shower, which makes it possible to cover the entire useful height of the enclosure. The incidence of air jets with tangential effect, favors the total detachment of the particles since a frontal incidence would cause the force of the air jet to produce an increase in adhesion of the particles to the surface instead of their separation.

Likewise, a good design and placement of the air returns is essential, which ensures the removal of the particles from the enclosure effectively and immediately to avoid that the detached particles can be deposited again or remain inside the shower and go outside with the door opening. In the showers, the particles are dragged by the crash of high-speed air jets.

In addition, by high filtration of the air before being driven inside the cabin, a very low particle level is achieved. The cabins have an automatic start-up system and interlocks that can be programmed according to the needs of each cabin. Depending on your application, two basic types can be differential air shower for people and air shower for materials.

Characteristics of Air Showers:

As for their construction characteristics, they are usually made of stainless steel.

They consist of two doors; one for access and one for exit, with a gasket and electromagnetic interlocking system that prevents its simultaneous opening and while the cleaning cycle is in progress. In case of emergency they are equipped with an internal and external push-button that cancels the operation and blocking of the doors. The interlocking device of the doors of the air shower prevents the simultaneous opening of both, thus establishing an efficient barrier that prevents the exchange of air between areas of different classification and, therefore, the transfer of particles.

The equipment has a programmable controller, which governs all the operating parameters of the equipment, including the flow of people, the activation time of the fan or the delay in opening the doors. Its operation is produced by a presence detector once the doors are closed. An emergency button is installed inside the cabin to interrupt the air cleaning cycle and unlock the doors if necessary.

Its operation, the duration and characteristics of the cycle, and even the possibility of differentiating between input and output cycles is fully programmable and adjustable to the user’s requirements through a simple control system, which allows the equipment to operate automatically.

In any case it is important to highlight that the most convenient to achieve maximum effectiveness is an enclosure for individual use in which the useful space must not exceed 80 – 90 cm.
