What is an Automatic Door Air Shower?

An automatic door air shower is a self-contained, enclosed chamber that uses high-velocity air jets to remove loose particles from people or objects entering or exiting a cleanroom or controlled environment. The air shower typically consists of two interlocked doors, a blower system, and a filtration unit. When a person or object enters the air shower, the outer door closes, and the blower system creates a high-velocity air stream that removes dirt, dust, and other particles from the surface of the person or object. The filtered air is then recirculated into the chamber through adjustable nozzles.


Working Principle of Automatic Door Air Showers

The working principle of an automatic door air shower involves the use of a high-efficiency particulate air (HEPA) filtration system and high-velocity air nozzles. The HEPA filter removes particles as small as 0.3 microns with an efficiency of 99.97%. The air shower system works by creating a high-velocity air stream that blows away dirt, dust, and other particles from the surface of a person or object. The nozzles are strategically placed in the chamber to direct the air stream at specific angles and velocities, ensuring complete coverage and effective particle removal.


Types of Automatic Door Air Showers

There are different types of automatic door air showers available in the market, including single person air showers double person air showers, and three-side air showers.


Single Person Air Showers

Single person air showers are designed for one person at a time and are typically used in small to medium-sized cleanrooms. They are compact and space-saving and can be installed in tight areas.


Double Person Air Showers

Double person air showers are designed for two people to enter simultaneously, making them ideal for larger cleanrooms or areas with high traffic. They are equipped with two interlocked doors and twice the number of nozzles compared to a single-person air shower.


Three-Side Air Showers

Three-side air showers are designed to accommodate large or bulky objects such as equipment, pallets, or containers. They feature three walls with nozzles to create an enclosed air shower chamber.


Installation of Automatic Door Air Showers

The installation of an automatic door air shower requires careful planning and consideration of the room's layout, size, and air flow requirements. The air shower unit needs to be installed in a way that ensures easy access for maintenance and cleaning. The electrical and plumbing connections must also be properly installed The electrical and plumbing connections must also be properly installed to ensure safe and efficient operation. It is essential to follow the manufacturer's instructions and specifications during installation.


Maintenance of Automatic Door Air Showers

Regular maintenance is crucial to ensure the optimal performance and longevity of the automatic door air shower. The maintenance tasks include filter replacement, cleaning of the chamber and nozzles, and inspection of the electrical and mechanical components. The frequency of maintenance depends on the usage and operating conditions of the air shower unit.


Benefits of Automatic Door Air Showers

Automatic door air showers offer several benefits to industries that require cleanrooms and controlled environments. These benefits include:
