Predator 750 portable air scrubber (negative pressure vacuum) by Abatement Technologies. This air scrubber has a three steps filtration system ideal for abatement, lead or mold decontamination, or just for general dust suppression work (concrete dust, sawdust and plaster dust or powder). It is commonly referred to as negative air machine in the construction field.

Abatement Technologies manufacturer’s code: PRED750HC

This air scrubber has three different modes: negative pressure mode, positive pressure mode, recirculation mode. The speed dimmer on the control panel allows one to control the airflow from 200 to 750 cfm (pi³/min in French).

It is equipped with three different filters which overlaps 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 vapours in low concentrations. This type of filter is particularly useful when it comes to mold decontamination 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 vapours in low concentrations (16 in X 16 in X 2 in) which also captures particles the size of 3 µm to 10 µm.

This air scrubber is certified UL94HB and CSA to comply with flammability requirements set by the responsible authorities. The Predator 750 molded body is made of unique resin which contains (United States Environmental Protection Agency) EPA-registered microbial growth inhibitors, and is as well UV-resistant. Moreover, the dual receptacle on the dashboard is protected with a ground-fault circuit interrupter. This equipment minimal power supply requirement is 120V/60 Hz. Its normal operating amps is 1.9 A which allows one to daisy-chain up to five units on one 15 A circuit.

The blue high density polyethylene cabinet is coated with TEFGARD® which eases its maintenance. The airflow intake and outtake have both a 10 in diameter. A panel opens on the side to allow filter changes. Moreover, it has been design for daisy-chained stacking.

The manufacturer’s recommends never plugging in more than 5 machines on one and the same 15 amps circuit. It is also recommended to stack a maximum of three machines after which it is better to make two stacks.

What we have here is one of the lightest and most portable filtration systems on the market. It weighs only 36 lb (16.3 kg) and features an ergonomic handle which makes it easy to move from one location to another.

Unit dimensions:
Length, 25 in X Depth, 19.5 in X Height, 20.5 in
(Length, 63.5 cm X Depth, 49.53 cm X Height, 52.07 cm)

Please note that on asbestos abatement or mold decontamination sites, a DOP test is required:

  • Before the start of a new development
  • Every time the unit is moved on work site
  • Every four weeks if the unit remains in situ during works
  • It is strongly advise to perform a DOP test on the site which is ready to start the work

The DOP test (Dispersed Oil Particulate) has been designed to ensure the integrity and efficiency of HEPA filters in terms of airborne particles containment based on their holding capacity of dispersed oil particulate of 0,3 µm. This type of test is a requirement because it pinpoints any leaks on the HEPA filter, that is, through its accordion-shaped material, its frame or its seals. Note that if particles go around the HEPA filter, the DOP test has failed.

HEPA filters are certified accordingly to current applicable regulations and a certification label shall be placed on the frame of the filter.

Intended as a guideline, here is the mathematical formula to determine the number of air scrubber required according to a given volume. For example:

Step 1, calculate the total volume of the work site
           Volume = Length X Width X Height = result in ft³
Step 2, establish the number of air changes required per hour; Québec regulations require 4 air changes per hour, but elsewhere, it is normally 6 changes of air per hours.
Step 3, find out how many cfm your air scrubber can generate
Step 4, to find out the number of air scrubbers required
           Number of air scrubbers =            volume in ft³
                                                   15 min X air scrubber cfm
Step 5, round off to the next whole number

Example: Predator 750 cfm air scrubber & a 10000 ft³ volume
Step 1: 10 000 ft³
Step 2: 4 air changes per hour, so 1 air change every 15 min
Step 3: Predator 750 has a capacity of 750 cfm
Step 4:                 10 000 ft³       = 0.88 air scrubber
                     15 min X 750 cfm
Step 5: rounded off, 1 air scrubber is required

According to these calculations, only 1 Predator 750 is required on work sites in Quebec. Please consider that this result is theoretical since it only takes into account ideal conditions, that is, a perfect airtightness. However, in practice, it requires more cfm to offset the prospective leaks and loss of airflow intake. Opening a door to transfer wastes from one zone to another, power fluctuation, the length of the outlet pipe which may reduce the air scrubber airflow and the saturation level of the filters are all potential source of negative pressure loss. We thus recommend you foresee a more powerful air scrubber than what you theoretically need or more machines than calculated to ensure a safe work environment.
