HEPA-AIRE® Negative Air Machine — H2KM

Overview

The HEPA-AIRE® H2KM is a contractor-grade portable negative air machine with two fixed speeds (2,000 / 1,300 CFM), a rugged 20-ga galvanized steel cabinet, and a true 99.97% @ 0.3 µm HEPA final filter. It rolls through standard doorways and runs on a normal 120 V / 15 A circuit—ideal for abatement, restoration, and healthcare construction.

Features

• High/Low airflow: 2,000 CFM (High) and 1,300 CFM (Low) via 1 HP two-speed motor

• Three-stage path: 1" polypad prefilter → 2" pleated prefilter → true HEPA; optional VAPOR-LOCK® carbon prefilter

• HEPA performance: Individually tested and certified 99.97% @ 0.3 μm

• Job-site build & mobility: 20-ga galvanized steel, swing-out prefilter door with cam latch, two fixed + two locking 4" swivel casters

• Controls & safety: Visual filter-change indicator (lamp); independently safety-tested to UL/CSA requirements

Specifications

• Airflow (clean filters): 2,000 CFM (High) / 1,300 CFM (Low)

• Power: 120 VAC, 60 Hz, 15 A circuit; normal operating current ≤ 10 A

• Motor: 1 HP, 2-speed; thermal overload protection, auto-reset (single-phase)

• Sound level: ~70 dBA @ 5 ft on High

• Dimensions / Weight: 35.75" L × 26" W × 30.25" H; 124 lb with 6" HEPA

• Cabinet: 20-ga galvanized steel

• Ducting: 12" outlet port; 12" inlet via optional plastic adapter

Installation (setup & use)

1. Position & secure: Place on a level surface; lock swivel casters.

2. Select mode:

   • Negative pressure: Exhaust filtered air to a safe location; monitor differential pressure with a calibrated gauge.

   • Recirculation / Positive supply: Return or supply filtered air to the target space per protocol.

3. Ducting: Attach 12" flex duct to the outlet; for inlet ducting, use the 12" adapter. Keep runs short and minimize bends.

4. Power: Plug into a 120 V / 15 A circuit. If an extension cord is unavoidable, use grounded 12-gauge, total length ≤ 50 ft.

5. Start & verify: Set speed (High/Low), check the filter-change indicator, and verify target pressure/airflow for the containment. Auto-restart occurs after brief power interruptions.

What’s in the Box

• H2KM negative air machine (on casters)

• 1" polypad prefilter (installed)

• 2" pleated prefilter (installed)

• 6" HEPA filter (installed, individually tested)

• User/installation manual
  (Compatible options: carbon prefilter, 12" deep HEPA, 12" inlet adapter.)

Important Details

• Safety: Indoor use; not intrinsically safe—do not use in explosive/IDLH atmospheres or near ignition sources; avoid solid-state external speed controls.

• Performance planning: Published CFM is with clean filters and minimal duct losses; real-world airflow drops with filter loading, reduced voltage, and long/bent duct runs.

• Compliance: Independently tested to relevant UL/CSA safety requirements.

Warranty

1-year limited warranty to the original user against defects in materials/workmanship (filters/consumables excluded). Use of non-approved parts/filters may void warranty and performance claims. Keep proof of purchase for service.
