Clean rooms and other critical environments must maintain specific particle counts, air changes per hour, and pressurization relationships to function correctly. Air Systems Balancing tests and certifies these spaces to ISO 14644 classification requirements, verifying airflow, room pressure differentials, and filter integrity. We work with pharmaceutical, laboratory, and manufacturing clients to keep controlled environments in spec on a recurring basis.
OSHA requires annual testing of laboratory fume hoods. Air Systems Balancing measures face velocity at multiple points across the hood opening to confirm it's containing fumes as designed. If a hood is out of spec, we identify the cause and help get it back into compliance.
Biosafety cabinets must be tested annually to NSF/ANSI 49 standards to confirm they're protecting personnel, product, and the environment as designed. Air Systems Balancing tests inflow and downflow velocities, checks HEPA filter integrity, and verifies proper airflow patterns. If a cabinet fails, we identify the cause and help get it back into certified operating condition.
Fire and smoke dampers should be inspected and tested annually to ensure their function for the safety of the inhabitants of a building.
Hospital isolation rooms, operating rooms, and nuclear imaging rooms require scheduled testing to verify air changes per hour and room pressurization. Air Systems Balancing performs this work for hospitals throughout the region to help protect patients, staff, and public health.
Air Systems Balancing tests and balances exhaust systems of every kind, including paint spray booths, dust collection systems, welding exhaust, and general industrial ventilation. We measure airflow at each hood, capture point, or duct branch to confirm the system is pulling the volume it was designed to move — not just at the fan, but at every point where contaminants need to be captured. Undersized or unbalanced exhaust means fumes, dust, or particulate escape into the workspace instead of leaving it. We identify where a system is falling short and help get airflow back to design specifications.
