The DefendAir HEPA 500 is a negative air mover as well as an air scrubber that helps create a cleaner, safer indoor environment. Fully adjustable 562-713m3 airflow and will generate more than seven air changes per hour in a 100m³ room or can be connected to 12" flexible ducting for use in cleaning duct work.

Not only is an air scrubber an essential tool when handling 'dirty' jobs such as removing harmful particulates that have been stirred up by air movers used during 'clean' drying. 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 job.

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