Industrial-Grade Negative Air Machines
Industrial-grade negative air machines neutralize odors and remove particles such as dust, lead, mold, and debris from the air in abatement, restoration, construction, and demolition applications. They have higher airflow and clean air more efficiently than air cleaners, but they are also louder than air cleaners. Negative air machines can be placed in a space to filter and recirculate air within that space. They can also be connected to flexible ducting to exhaust contaminated air out of a space, which is known as negative-pressure air cleaning. Each machine consists of a blower that moves air through the machine and multiple filters that trap airborne contaminants as the air passes through them.
