Can I use the calculator for my air machine?

Most likely, yes!

The AirScrub calculator works for Negative Air Machines (NAM), Air Filtration Devices (AFDs), Air Handling Units (AHU), HEPA Air Movers, Air Scrubbers, and other air machines.

What is an air scrubber?

Expand or Collapse Section

Air scrubbers remove contaminants from the air. They are designed to control indoor air quality by filtering out particulates, gases, and chemicals. For example, air scrubbers are used to remove dust, mold, asbestos, as well as odors.

Air scrubbers can also be used like a negative air machine by using ducting – air flow tubes.

What is a negative air machine?

Negative air machines move and filter contaminated air. They use ducting – air flow tubes – to direct the air from inside of a containment area to outside or another area. This also creates negative air pressure in an area that is helpful in limiting the spread of contaminants.
