Positive Air Pressure

Positive air pressure is a flow of HEPA filtered air onto a desired object or chamber. Our positive air pressure systems are designed to reduce the amount of airborne contaminants in a given area by using powerful fans to pull ambient air through HEPA or ULPA filters into your work area.

Our modular line of positive air pressure systems are designed to reduce the amount of airborne contaminants in a given area by using powerful fans to pull ambient air through HEPA or ULPA filters into your work space. Our application specialists can assist you in selecting the appropriate size filter/fan unit for your specific space and ISO classification desired.

Positive Pressure Room

Cleanrooms are often classified into 2 categories of air pressurization: positive and negative. Positive pressure systems are normally used for non hazardous air applications, where the air and fumes pushed through the gaps, due to the positive air pressure, is not harmful to the user or immediate environment. The amount of particulate cleaned is dependent on the cleanroom design, amount of CFM and the filter used in conjunction with the positive pressure system.

This ISO Class 5 rated positive pressure system has been used in a variety of applications including compounding, stem cell therapy practices and other medical applications, tissue culturing, data recovery, manufacturing, cleaning processes, and much more.
