Negative Air Pressure Cleanrooms
Negative air pressure cleanrooms are used for hazardous manufacturing processes. Negative air pressure cleanrooms are also used for BSL level P - 2, P - 3, and P - 4 Bio-Safety cleanrooms for production and medical research.
Negative Air Pressure Cleanrooms - Hazardous Process Facilities
Some cleanrooms are required to be operated at negative air pressure for hazardous processes.
Modular BSL P-2 - General Clean Laboratories
BSL P-2 clean labs. normally operate at marginal cleanliness levels with slight negative air pressure.
Modular BSL P-3 - Bio-Hazard / Containment Clean Laboratories
BSL P-3 bio-hazard containment labs. operate at various cleanliness levels with 100% once-through air pass, with specific negative air pressure levels with automatic pressure control and 100% exhaust through a HEPA filter system.

Portable BSL P-2 and P-3 Containerized Portable Clean Laboratories
Level BSL P-2 and P-3 Clean Labs. are also manufactured in portable, heavy duty sea containers for deployment world wide.
Mobile (truck mounted) BSL P-2 and P-3 Clean Laboratories
Level BSL P-2 & P-3 clean labs. are manufactured using various sizes of standard truck bodies and mounted directly on the truck chassis for "drive-anywhere" capability.
