Abatement Technologies H2KM Negative Air Machine – 2000 CFM, 3-Stage HEPA

Abatement Technologies HEPA-AIRE H2KM — 2,000 CFM Negative Air Machine and Air Scrubber

The Abatement Technologies HEPA-AIRE H2KM is an industrial-grade, dual-speed negative air machine delivering 2,000 CFM on high and 1,300 CFM on low through a three-stage filtration system that terminates at a 99.97%-efficient HEPA filter. Built in 20-gauge galvanized steel and NRTL-certified (UL/CSA), it is the unit abatement contractors, restoration firms, and healthcare construction teams specify for asbestos, lead, and mold containment projects.

H2KM Filtration and Airflow Specifications

• Airflow: 2,000 CFM (high) / 1,300 CFM (low) — two operating speeds to match containment zone size and air-change requirements.
• Stage 1 filter: 1″ coarse particulate polypad pre-filter — captures large debris and extends downstream filter life.
• Stage 2 filter: 2″ pleated particulate pre-filter — intermediate filtration that loads before the HEPA, reducing replacement frequency.
• Stage 3: 6″-deep HEPA filter, 99.97% efficiency @ 0.3 microns — individually tested and certified at 2,000 CFM airflow; also accepts 12″-deep extended-life HEPA.
• Exhaust: 12″ duct collar (inlet and outlet) — connects to standard 12″ flex duct for negative air exhausting or recirculation.
• Motor: 1 HP, two-speed, thermal overload protection with auto-reset — single-phase, 115–120V AC, 60 Hz, 15-amp circuit.
• Cabinet: 20-gauge galvanized steel; dimensions 35¾” L × 26″ W × 30¼” H — withstands abatement job-site conditions.
• Weight: 124 lbs (standard filters); 151 lbs (with H2010M extended HEPA) — four casters (two locking swivel, two fixed) for repositioning.

Air Scrubber Mode vs. Negative Air Machine Mode

The H2KM operates in two distinct configurations. In recirculation (air scrubber) mode, contaminated room air enters through the inlet manifold, passes through all three filter stages, and exhausts back into the same space — continuously reducing airborne particle counts without ducting. This mode is appropriate for mold remediation and general construction dust control where negative pressure is not required by regulation. In negative air machine mode, the 12″ exhaust collar connects to flex duct that routes filtered air outside the containment zone, creating negative pressure that prevents cross-contamination. Asbestos and lead abatement projects governed by EPA and OSHA standards typically require documented negative pressure, which the H2KM maintains with either its 2,000 or 1,300 CFM speed selected to match the containment volume and required air changes per hour.

ICRA Compliance, Xactimate Coding, and HEPA Filter Specs

In healthcare construction governed by ICRA (Infection Control Risk Assessment) protocols, the H2KM satisfies the requirement for HEPA-filtered negative air pressure at Class III and Class IV risk project sites. Its NRTL certification (UL/CSA) satisfies facility safety requirements without a variance. For insurance restoration billing, the H2KM air scrubber mode is billable under Xactimate line item AQRS (Air Quality — Rental, per day), a code recognized by major property insurers for covered remediation losses. The standard 6″-deep HEPA filter is individually tested and certified — certification documentation ships with the unit. Contractors requiring extended filter life between change-outs can specify the 12″-deep H2010M HEPA, which increases the unit’s weight to 151 lbs but substantially reduces consumable costs on long-duration projects. The swing-out filter door provides tool-free access for filter inspection and replacement without repositioning the unit.
