Air-Flow Calculator for Negative Air Machines

A negative air machine is an essential device for contained spaces such as construction sites, hospitals, testing labs and clean rooms where clean air is a necessity. But how do you know which model you should get for your space? After all, a machine that's too small won't adequately remove the dust, toxins and odors that might build up. But too large a machine will waste money on operating costs. Spycor Environmental wants you to get the best machine for your needs, and our negative air machine air-flow calculator will help you find it by matching a machine to your unique situation.
