Modular Hardwall Positive Air Pressure Cleanrooms

Cleanrooms are classified into 2 categories of air pressurization, positive and negative air pressure cleanroom HVAC ( Heating,Ventilating and Air Conditioning ) systems. Positive air pressure cleanrooms systems are normally used for Electronics, Aerospace,Optics, Military and Defense applications, and Research, etc., where the air escaping from doors, ceilings, or walls, due to the positive air pressure, is not hazardous and not creating safety or health concerns. The amount of particulate cleanliness required determines the cleanroom design concept, amount of air filtration, CFM (cubic feet per minute) and total HVAC. Our positive pressure cleanroom designs are based on years on experience in air pressurization in a vast variety of applications.
Positive Air Pressure Cleanrooms normally operate in an air pressure range of 0.02 in. to 0.2 in water column (H20). Positive air pressure means the cleanroom or rooms are "pumped up" with more filtered air then the surrounding space outside the cleanroom(s).
There are different cascading levels of positive air pressure from the cleanest rooms at the highest pressure down to the gown room/or airlock room.Electronics Cleanrooms, Aerospace, Optics, Research, Military, Defense, Etc.
This style of cleanroom design normally involves products research, manufacturing, or repair & calibration that does not normally require the room surfaces, and equipment to be sanitized or sterilized to eliminate microbial contamination.
