Negative Air Machines

Ensure the air in your workspace is clean, safe and breathable by using a negative air machine with HEPA filtration.  Abatement projects, building renovations, healthcare settings, and any other environment in which potentially dangerous contaminants (dust, debris, mold, microbes, particles etc.) are floating through the air can benefit from a negative air machine, which draws the contaminants out of the air and exhausts them out safely through HEPA filtration.

What is a negative air machine and how does it clean air?

Negative air machines are used to clean the air and create positive or negative air pressure in medical facilities, factories, commercial buildings, job sites, and in confined spaces with mold, asbestos, or lead. Negative pressure isolates a space and prevents the spread of debris or infectious pathogens from a room; positive pressure protects those inside the room, keeping outside air from getting in and harming immunocompromised patients.

What is the difference between an air scrubber and a negative air machine?

An air scrubber stands alone in the center of a room with no ducting attached. A negative air machine uses ducting to remove contaminated air from a sealed containment area.

What are the advantages of using HEPA filters?

HEPA filters are made up of thousands of extremely fine fibers which are arranged specifically to intercept debris of all sizes including very small, microscopic particles, in turn making the air you breathe cleaner and safer.

Where can your selection of negative air machines be installed?

Homes, hospitals, jobsites, schools… Negative air machines can convert rooms to airborne infectious isolation rooms and abatement workspaces and provide safe breathing air in a confined building such as schools and homes. With the machines fan air is forced through a HEPA filter and out of the room via ducting. The principle is to create lower pressure inside the room so that pathogens and fibers will have a hard time escaping into the rest of the facility.  For effective isolation, a room must be well-sealed. Prior to installing a negative air machine all windows, doors, and any other places where air could be drawn in must be sealed off. The less air leakage, the more efficiently the air pressure differential can be maintained.
