Positive Pressure Clean Room

Positive air pressure means the cleanroom or rooms are pumped up with more filtered air then the surrounding space outside the cleanroom s.

Positive pressure clean room.

When the door of the cleanroom is opened or if the cleanroom experiences a structural breach the pressure disparity forces. In medical settings these rooms prevent the spread of infectious contaminants and maintain sterile or restricted spaces and are also referred to as protective environments positive pressure rooms and airborne infection isolation rooms aiir negative pressure rooms. With cleaned air being sucked in and contaminants being ejected positive pressure cleanrooms are classified according to the concentration of airborne particles inside of them and the size of those particles the goal being to minimize the number and size of the particles in a clean room through. This is in contrast to a negative pressure room where air is sucked in.

Consequently if there is any leak from the positively pressured system it will egress into the surrounding environment. Positive pressure is used in cleanrooms where the priority is keeping any possible germs or contaminants out of the cleanroom. This is achieved through the use of an hvac system which pumps clean filtered air into the structure. Positive pressure is a pressure within a system that is greater than the environment that surrounds that system.

A positive air pressure cleanroom has an air pressure level that is greater than that of the surrounding environment. Use is also made of positive pressure to ensure there is no ingress of the environment.
