Negative air machines and air scrubbers for demolition projects provide air filtration for construction, abatement, and restoration work. Spycor Environmental offers OmniAire 2200-series machines, Mintie Pure Air Blaster units, NC Filtration models, and the Abatement Technologies PAS5000, listed at 4,000 CFM peak airflow.
Contractors can compare operating airflow, filtration configuration, power requirements, duct connections, and portability. Size equipment for containment volume and project requirements, accounting for filter and duct resistance. Confirm whether the selected configuration includes HEPA filtration and verify pressure when operating as negative air.
