Outside The Cleanroom: The Importance of Air Showers

May 7, 2012

Cleanrooms are great at maintaining a contaminant-controlled environment, with expertly engineered filtration systems, humidity and temperature controllers, and construction to ensure a totally contamination free workspace. Filters in the cleanroom can only do so much, though, and the job of keeping a cleanroom clean really starts well before anyone sets foot in it. Air ShowerThe main purpose of filtration in a cleanroom is to keep microscopic airborne particles from entering the space – they’re not designed to eliminate the everyday dirt, dust, and other particles that accumulate on people and objects who are entering the cleanroom. That’s where the air shower enters the picture.

Depending on the application required in the cleanroom, the air shower can be an integral part of the cleanroom setup. Basically, it does the heavy lifting of cleaning that everyday particulate matter off of a person who is properly attired for cleanroom entry, or object, prior to entering the cleanroom space.  A system of high pressure air nozzles spray clean air at high pressure on the entrant, literally scrubbing the entrant of forbidden contaminants. Filters trap  the dirty air  and keep it out, allowing the user to move into the cleanroom as contaminant-free as possible. That initial step of entering an air shower to remove particles from the people or objects entering the cleanroom, allows the cleanroom filters themselves to work at as high an efficiency as possible, ensuring that the cleanliness level of the cleanroom and the project within it are maintained.

We feature a full line of air showers here at Liberty Industries, and we can also build to your custom requirements. Contact us for more information!  To see an air shower in operation, watch this video.
