WHAT'S A CLEANROOM

Indoor air quality is of paramount importance for human comfort and health. Air, whether it is from outside or re-circulated within the area, acts as a vehicle for airborne contaminants brought in by the movement of people, material, etc. Since many of these airborne contaminants are harmful either to products or people working in such environments their removal is necessary on medical, legal, social or financial grounds. ​ see more...

KEY ELEMENTS OF CLEANROOM DESIGN

Four fundamental rules apply to cleanrooms.
1) First, contaminants must not be introduced into the controlled environment from the outside.
2) Second, the apparatus or equipment within the controlled environment must not generate or otherwise give rise to contaminants (for example as a result of friction, chemical reactions, or biological processes).
3) Third, contaminants must not be allowed to accumulate in the controlled environment.
4) Fourth, existing contaminants must be eliminated to the greatest extent possible, and as rapidly as possible.

HVAC SYSTEM DESIGN FOR CLEAN FACILITY

HVAC systems in cleanrooms are dramatically different from their counterparts in commercial buildings in terms of equipment design, system requirements, reliability, size and scale.
