Compare airflow and equipment formats

• Abatement Technologies HEPA-AIRE H2KM: a two-speed machine rated at 1,300 and 2,000 CFM, with a steel cabinet and casters.
• Abatement Technologies Predator 750: a portable air scrubber with variable airflow from 200 to 750 CFM.
• NIKRO PS1000: a 1,000 CFM upright polyethylene model.
• Novatek Novair 2000 F2100: compare its 1,000/2,000 CFM settings and portable cabinet with other larger units.

Air scrubbing and negative-air containment

An air scrubber can filter and recirculate room air. Negative-air containment uses filtered exhaust routed out of the contained area to help maintain inward airflow. Confirm that the selected machine, duct connection and project setup support the intended use; a machine's rated CFM alone does not verify containment pressure.

Use our air change calculator to estimate airflow from room volume and your specified air-change target. Allow for the actual setup, including duct runs and filter loading, and verify performance on site. Compare electrical requirements, replacement filter sizes and transport access before choosing equipment. For smaller enclosed work areas, also review mobile containment carts and cubes.
