Cleanroom Air Shower Specification Standards

Air showers operate similarly to automated car wash pressure washer systems, utilizing multiple steps throughout the decontamination process. The following cleanroom air shower specifications process details the operational aspects of a cleanroom air shower. Single Person Double Sides Flow Stainless Steel Air Shower


1、The worker passes through the entry door and a sensor activates interlock magnets, which lock the air shower and cleanroom doors.

2、Numerous adjustable nozzles blow high-velocity streams of Class 100 filtered air onto the worker.

3、The high-velocity air creates a flapping effect on clothing which produces a scrubbing action, removing particulates from cleanroom garments.

4、To ensure all particulates are removed, workers raise their arms and rotate in place.

5、Indicator lights signal the end of the cleaning cycle, and the cleanroom door opens.

Important factors to consider when specifying an air shower include effectiveness (power and capacity) and air filtration.Main Components Of The Air Shower

Effectiveness — Power and Capacity

Power and capacity are the major influences on the effectiveness of an air shower. Cleaning power is determined by nozzle velocity: the speed at which air is pushed through the nozzles. It takes high-velocity air to dislodge contaminants; the higher the velocity or cleaning force, the more contaminants are removed. Conversely, capacity is the volume of air circulated in the system. More air volume means faster cleaning and removal of contamination through the filtration and recirculation system.What Makes Air Showers So Special For Cleanrooms?


To specify the most effective air shower, look for one that produces nozzle velocities of 7,800 feet per minute (fpm) and circulates 1,900 cubic feet per minute (cfm) of air. Velocity is measured at the nozzle, and cleaning effectiveness deteriorates as distance from the nozzle increases.How To Choose Cleanroom Walls


Therefore, air showers should have a high number of air nozzles positioned as close to the worker or product as possible. Ideally these nozzles should be able to be positioned and removed to allow for easy inspection of the high-pressure supply ducts. How Do Air Showers Work?

Air Filtration

An air shower’s recirculating air filtration systems typically use two sets of filters. The first is a pre-filter for catching the bulk of contaminants. The second is a high-capacity, 99%-efficient HEPA filter. 

System blower units are usually mounted in the ceiling. If your facility has height restrictions, make sure the blowers can be mounted on the external wall. For easy routine maintenance, pre-filters should be changed regularly. Replacement filters are economical and easy to change. What are the available air shower designs and configurations
