Exhaust Air Unit (EAU) is a critical ventilation system used in pharmaceutical, biotech, and cleanroom facilities to safely remove contaminated or used air from controlled environments. Its main purpose is to maintain cleanroom integrity by extracting air that may contain dust particles, chemical fumes, heat, or microbial contamination.
The unit ensures proper air balancing by continuously removing exhaust air while maintaining required pressure differentials between clean and non-clean areas. This helps prevent cross-contamination and maintains GMP-compliant cleanroom conditions.
