Typical Applications:

  • Air Purification
  • Odour Removal
  • Dust removal
  • Restoration


Not only is an air scrubber an essential tool when handling 'dirty' jobs such as those involving sewage or mould, but it's also great for removing harmful particulates that have been stirred up by airmovers used during 'clean' drying of leaks and spills. The HEPA 500 works fast: one unit running at maximum speed will generate more than seven air changes per hour in a 100 M³ room, and helps to restore any environment to a pre-loss condition fast - the ultimate goal of every restoration job.

Improve IAQ:

Use an air scrubber to improve everyday indoor air quality, increasing productivity and reducing the incidence of asthma and other illnesses in office workspaces and public buildings; to eliminate stale air pockets; or to purify air and remove lingering odours after cleaning, moisture intrusion, fire and smoke damage or sewage back-up. High-efficiency filtration also helps improve the air quality during construction and renovations or after installation of new carpets, etc.
