Air change rate for cleanrooms with non-unidirectional airflowAir change rate (ACR) is widely used in the specification of cleanrooms, partly by tradition and partly to compare different cleanrooms or designs. Recommended ACRs have also been a feature of guidelines and standards over the years,...
A well-designed air handling system should deliver both “fresh” and “recirculated” filtered clean air into the cleanroom in such a way and at a rate so that it flushes the particles from the room. Depending on the nature of the operations, the air taken out of the room is usually ...
Room air-change rate Air supply to the cleanroom should provide a room air-change rate of > twenty (20) per hour. Air cleanliness will be enhanced by higher air-change rates, e.g. > 30/h - typically, heat load calculations result in such a rate. When the doors are open, the ...
Air change rates help facilities determine the design and performance criteria for a cleanroom’s air system. The total air change rate, flow pattern, and efficiency of the exchange have an impact on the cost and performance of a cleanroom. ...
Air change rate This refers to the number of times the air is changed within a cleanroom. It is calculated by taking the total volume of air introduced into the cleanroom over an hour and dividing it by the volume of the room. It is expressed as air changes per hour (ACH), and for...

A cleanroom with ineffective filters isn’t a cleanroom at all. That’s why it’s important to perform regular inspections and routine maintenance on your cleanroom filtration system. Depending on your unique application and ISO classification requirements, your cleanroom filters’ maintenance schedule...
