Portable negative air machines provide movable filtered-exhaust equipment for construction, renovation, and remediation containment. Spycor Environmental carries NC Filtration, OmniAire, and NIKRO machines, including compact models and larger wheeled units. Contractors can compare filtration configuration, operating airflow, exhaust connections, electrical requirements, weight, and transport features.
Selected models also operate as recirculating air scrubbers. Match equipment to room volume, required air changes, duct resistance, and the containment layout, then verify installed pressure performance. For odor-control applications, check the specified carbon filtration rather than relying on HEPA particulate filtration alone.
