A cleanroom is a controlled environment whereby dust, airborne microbes, aerosol particles and other pollutants are filtered out to provide an aseptic space.

Negative air pressure cleanrooms are designed to stop contamination from escaping the cleanroom. They are often used during biochemical testing or in a hospital to confine patients with acute infectious diseases.

The concept is to produce low air pressure within the cleanroom using filters. Clean air flows in through the door filters, and contaminated air is drawn out through the ceiling, while windows and doors are sealed to stop contamination from spreading.

We have 50 years of experience in fan design and development and our range of centrifugal fans provide the perfect solution for cleanroom air configuration. Our fan offering comprises of multi-stage fans for low volume air requirement or small to medium fans for higher airflow needs.
