Predator 750 portable air scrubber with airflow from 200 to 750 cfm

A professional air purifier for high-risk environments

Manufacturer code from Abatement Technologies: PRED750HC

This portable air purifier offers three functions: negative pressure mode, positive pressure mode and recirculation mode. The speed control dial on the control panel allows airflow adjustment between 200 and 750 cubic feet per minute (cfm).

It is equipped with three stacked filters in a specific order. The purifier includes a primary filter, a pleated secondary filter and a HEPA filter. It is now possible to replace the secondary filter with another one that protects against harmful organic vapors. This type of filter is especially useful during mold removal work.

•  The primary filter (SAH1FP) (16 in X 16 in X 1 in) captures bigger particles the size of 10 µm and more.
•  The secondary filter (SAH1FS) (16 in X 15.5 in X 2 in) captures particles the size of 3 µm to 10 µm.
•  The HEPA filter (SAH1F) (16 in X 16 in X 6 in) captures smaller particles the size of 0.3 µm and more with 99.97% efficiency.
•  In option, a secondary filter (SAH1FSOV) of activated coal for protection from organic vapors in low concentrations (16 in X 16 in X 2 in) which also captures particles the size of 3 µm to 10 µm.

The Predator 750 from Abatement Technologies is a negative pressure machine that ensures optimal air purification in confined areas. It features a three-stage filtration system, including a primary filter, a secondary filter and a HEPA filter certified at 99.97% efficiency. This portable air purifier adapts to the specific needs of each job site thanks to its adjustable airflow and three operating modes: negative pressure, positive pressure and recirculation.

The Predator 750 operates on a standard 120V/60 Hz circuit and consumes only 1.9 amps, allowing up to five units to be connected on a single 15-amp circuit. It is equipped with a dual electrical outlet fitted with a ground fault circuit interrupter (GFCI), providing additional protection against electrical hazards.

Its blue polyethylene housing is coated with TEFGARD®, designed to facilitate maintenance and extend the life of the device. With a 10-inch diameter air inlet and outlet, the housing opens laterally for quick filter access. It is also designed to allow the stacking of multiple units, although the manufacturer recommends not stacking more than three units for stability and performance reasons.

Weighing only 36 pounds, or 16.3 kilograms, the Predator 750 is one of the lightest and most portable air filtration systems on the market. Its ergonomic handle makes it easy to transport, even in the most demanding environments. Its compact dimensions — 25 inches wide, 19.5 inches deep and 20.5 inches high — allow for easy integration into containment zones.

The Predator 750 portable air purifier stands out for its compliance with UL94HB and CSA flammability standards, meeting the requirements of regulatory authorities. Its molded body is made from a special resin approved by the United States Environmental Protection Agency (EPA), enriched with bacterial growth inhibitors and UV resistance. This level of certification ensures safe use in high-risk environments, particularly during asbestos removal or decontamination work.

Technical specifications of the Predator 750 air purifier:

The Predator 750 features HEPA filtration capable of capturing particles down to 0.3 microns, an antimicrobial resin housing approved by the EPA, and compliance with UL94HB and CSA flammability standards. Its control panel allows precise airflow adjustment, and its compact format facilitates transport and installation on job sites.

Simple and fast installation of the Predator 750 SAH1 air purifier:

To install the Predator 750 air purifier, simply place it in the containment area, connect the exhaust hose to the air outlet, and plug it into a standard 120V/60Hz outlet equipped with a ground fault circuit interrupter. Speed adjustment is done directly on the control panel, allowing immediate adaptation to site conditions.

Maintenance of the air purifier for lasting performance:

To maintain maximum efficiency, it is recommended to regularly replace the primary, secondary and HEPA filters. The housing should be cleaned with a damp cloth and a non-corrosive product. It is also advisable to periodically check the proper functioning of the circuit breaker and controls to ensure the safety of the device.

Optimal use of the Predator 750 for decontamination:

Negative pressure mode is particularly suitable for asbestos removal work. It is recommended to plan for six air changes per hour in confined areas to ensure effective purification. The choice of secondary filter can be adjusted based on the contaminants present, including fine dust or organic vapors.

Frequently asked questions about the Predator 750 air purifier:

What is the lifespan of the Predator 750 HEPA filter?

The HEPA filter maintains its efficiency for several months, depending on usage intensity and job site conditions.

Is the Predator 750 suitable for small job sites?

Thanks to its compact format and adjustable airflow, it is perfectly suited for areas under 7,500 cubic feet.

Can Predator 750 be used for general dust control?

Yes, this air purifier is effective against dust from concrete, wood, plaster and other fine particles.

How to calculate the number of air purifiers needed based on the volume of the work area:

To ensure air quality that meets current standards, it is essential to accurately determine the number of air purifiers required for a containment zone. The calculation is based on several simple parameters.

The first step is to measure the total volume of the work area in cubic feet by multiplying the length, width and height of the space. Next, determine the number of air changes required per hour. In Quebec, regulations require four air changes per hour (each 15 min), while elsewhere, the standard may be six changes.

Once these data are established, identify the airflow (in cfm) generated by the purifier model used. For Predator 750, the maximum airflow is 750 cfm. The number of units needed is calculated by dividing the total volume by the product of the purifier’s airflow and the duration of a 15-minute cycle for use in Quebec. The result should then be rounded up to the nearest whole number to ensure adequate coverage.

Here’s a concrete example: for a 10,000-cubic-foot area and a 750 cfm airflow, with one air change every 15 minutes, the calculation is as follows:

10,000 ÷ (15 X 750) = 0.88

Rounded up, one Predator 750 air purifier is needed. However, this theoretical calculation assumes ideal conditions, including perfect sealing of the area. In practice, it is recommended to allow for an additional margin to compensate for pressure losses due to door openings, filter saturation, duct length or electrical fluctuations. For added safety, using two units may be advisable.
