Abatement Technologies H1990M Negative Air Machine – 1600 CFM, 1 HP, HEPA

H1990M Negative Air Machine — 1,600 CFM HEPA Containment in a 125-Pound Portable Unit

The Abatement Technologies HEPA-AIRE H1990M is a dual-speed negative air machine built for jobs where the H2KMA's 2,000 CFM output is more than needed — or where weight and footprint matter. At 125 lbs with a compact profile, it fits through standard doorways, into crawlspaces, and into patient rooms where larger units cannot. On high speed it moves 1,600 CFM; on low it drops to 1,050 CFM for maintenance-level air changes. The 20-gauge galvanized steel cabinet and cam-latch filter door are built for repeated job site use across multi-year service life.

H1990M Dual-Speed Airflow and Containment Capability

The two-speed motor lets crews match airflow to the containment zone size and project phase — high speed for active abatement or demolition, low speed for passive drying or maintenance filtration.

• 1,600 CFM on high speed — delivers 4+ ACH in containment zones up to 24,000 cubic feet; sized for single rooms, suites, and small floor sections
• 1,050 CFM on low speed — suitable for maintenance filtration in smaller spaces or when noise reduction is required in adjacent occupied areas
• 99.97% HEPA filtration at 0.3 microns — certified for asbestos, lead, and mold containment per OSHA and EPA requirements
• 125-lb operating weight — lighter than the H2KMA; fits in crawlspaces, patient rooms, and elevator-accessed floors without mechanical assistance
• Swing-out hinged door with cam latches — quick filter changes without tools; no screwdrivers or wrenches required on-site
• 12" exhaust collar — standard sizing for flex duct; no custom fittings required for outside exhausting

H1990M Applications and Environments

Water damage restoration contractors use the H1990M for airborne particle control during demo and drying in residential bedrooms, bathrooms, and mechanical rooms where the H2KMA would be difficult to maneuver. Hospital renovation teams use it for ICRA containment in patient rooms, where the lighter weight allows elevator transport without a freight elevator. Asbestos abatement contractors working on school boiler rooms and pipe chases specify it where the compact footprint allows placement without reducing the working space in an already-tight containment zone. Mold remediation companies running residential jobs use it as a primary unit in rooms up to 2,400 square feet with 10-foot ceilings — a single H1990M at high speed delivers the 6 ACH recommended by IICRC S520.

H1990M Compliance and Insurance Billing

Xactimate line item code for air scrubbers: AQRS. NRTL-certified to UL and CSA safety standards. The 9-amp draw at high speed runs on a standard 15-amp circuit alongside other restoration equipment. Thermal overload protection is standard on the 1 HP motor.
