Air showers (also known as air blowers) are an important component in maintaining the air balance of clean rooms and controlled environments. The airflow from the air shower nozzles removes dirt particles from people and products before they enter a clean room.

In addition, the use of an air shower reduces the need for maintenance of clean rooms, since the penetration of contaminants into a clean room is minimized, overall energy consumption is reduced, and the life of HEPA filters in a clean room is extended.

SANBELA offers high-performance standard and individual air shower  systems for clean rooms.

CLEANROOM AIR SHOWER: PRINCIPLE OF WORK

The air shower is an autonomous air recirculation system.

Installed at the entrance to a clean room, thereby reducing the penetration of pollution when entering a clean production area.

The personnel passes through the air shower door, the door is automatically closed, and high-speed air filtered by HEPA filters blows from the adjustable nozzles. High speed air flow creates a clapping effect on clothing, which allows to remove contaminants from the clothes of cleanroom personnel. At the end of the cycle, the exit door automatically opens and the worker enters from the air shower into the clean room.

The standard cycle time is 10 seconds. The adjustable microprocessor allows you to adjust the “on-site” setting of the cycle time and other important parameter.

HOW TO CHOOSE THE RIGHT AIR SHOWER FOR CLEANROOM?

  • The system must be modular to simplify assembly (disassembly)
  • Air shower body must be made of stainless steel or painted steel
  • The blowing system must provide high speed and a large air volume for effective decontamination
  • The recirculation filtration system should include prefilters and HEPA filters
  • Air shower must have a large number of adjustable air nozzles
  • Air shower must have magnetic locking system.
