HEPA-AIRE portable air scrubber with airflow of 1300 or 2000 cfm. Ideal for asbestos abatement & decontamination workzone

A professional-grade air purifier for hazardous work environments

Abatement Technologies manufacturer’s code: H2KMA

This HEPA air purifier features a three-stage filtration system: a primary filter for large particles, a pleated secondary filter for medium-sized contaminants, and a certified HEPA filter that captures 99.97% of particles as small as 0.3 microns. An optional activated carbon filter is available for volatile organic compounds during mold remediation. This advanced filtration setup ensures compliance with air quality standards for asbestos removal, mold cleanup, and fine dust control. This purifier is equipped with a differential pressure gauge that indicates the saturation level of your HEPA filter.

It is equipped with three different filters, which overlap one another accordingly to a given order. The air scrubber comes with one set of filters, that is, a primary filter, an accordion-shaped secondary filter and a HEPA filter. It is now possible to replace the secondary filter by another secondary filter of activated coal for protection from organic vapors in low concentrations. This type of filter is particularly useful when it comes to mold decontamination work.

• The primary filter (SAHFP) (24 in X 24 in X 1 in) captures bigger particles the size of 10 µm and more.
• The secondary filter (SAHFS) (24 in X 24 in X 2 in) captures particles the size of 3 µm to 10 µm.
• The HEPA filter (SAHF) (24 in X 24 in X 6 in) captures smaller particles the size of 0.3 µm and more with 99.97% efficiency.
• In option, a secondary filter (SAHFSOV) of activated coal for protection from organic vapors in low concentrations (24 in X 24 in X 2 in), which also captures particles the size of 3 µm to 10 µm.

This air scrubber is certified ETL and meets UL and CSA requirements as for safety standards. This equipment minimal power supply requirement is 120V/60 Hz. Its normal operating amps is 9 A.

High-efficiency filtration and professional performance.

Technical specifications of the Hepa-Aire air purifier:

Weighing 124 lb (56.25 kg), the Hepa-Aire unit is built for mobility and durability. It includes four 4-inch casters—two fixed and two swivels—and four heavy-duty handles securely anchored to the base. The unit measures 35.75 in wide, 26 in deep, and 30.25 in high (90.81 cm × 66.04 cm × 76.84 cm), making it compact and easy to maneuver on job sites. The galvanized steel housing features a 12-inch circular air outlet for duct connection and a front-access panel for quick filter replacement. In addition, this purifier is equipped with a differential pressure gauge that indicates the saturation level of your HEPA filter.

Easy installation of the Hepa-Aire portable air purifier:

Installing the Hepa-Aire air purifier is straightforward and tool-free. Simply position the unit in the work area, connect the exhaust duct to the air outlet, and plug it into a standard 120v/60hz power source. Choose between low (1300 cfm) or high (2000 cfm) speed depending on the contamination level and room volume. The unit’s casters and handles make relocation effortless.

Maintenance and DOP testing for long-term efficiency:

To maintain optimal performance, regular maintenance is essential. Replace the primary filter frequently and monitor the visual indicator for the secondary and HEPA filters. For asbestos or mold remediation, DOP testing is mandatory. This test must be performed before starting work, every time the unit is moved, and every four weeks if the unit remains stationary. The DOP (dispersed oil particulate) test ensures the HEPA filter’s integrity by detecting leaks through the pleated media, frame, or seals. Certified HEPA filters will bear a label confirming compliance.

Usage tips for maximum air purification efficiency:

To determine how many air purifiers are needed, calculate the room volume (length × width × height), identify the required air changes per hour (typically 4 in Québec, 6 elsewhere), and know your unit’s cfm rating. Use this formula: Number of purifiers = room volume ÷ (15 min × purifier cfm)

Example for a 20,000 ft³ space: At 1300 cfm, 2 purifiers are needed. At 2000 cfm, 1 purifier is sufficient

These calculations assume ideal conditions with perfect sealing. In practice, you should plan for higher airflow to offset pressure losses due to door openings, filter saturation, duct length, and power fluctuations. For added safety, consider using a more powerful unit or combining two purifiers to maintain consistent negative pressure.

FAQ about the Hepa-Aire portable air purifier SAH2MA:

Is DOP testing required for all decontamination projects?

 Yes, DOP testing is mandatory for asbestos and mold remediation to verify the HEPA filter’s effectiveness and ensure job site safety.

How do I calculate how many purifiers I need?

Use the room volume, required air changes, and a purifier cfm to estimate the number of units. Always round up and consider practical airflow losses.

Can this purifier be used for general dust control?

 Absolutely. The Hepa-Aire unit is ideal for capturing concrete, wood, plaster, and other fine dust particles, making it suitable for general construction and renovation projects.
