Clean air is important in any work environment for the safety of employees, patients and more. If your job is subject to large amounts of dust, odor, mold and other breathable toxins, a negative air machine can help remove them. These air purification units use exhaust ducting to regularly draw new, fresh air into a containment area while filtering and removing the old air. We offer dozens of negative air machines that prevent contamination in a variety of construction, healthcare and lab environments. Whether you want to prevent excessive odors and fumes from painting or control dust during a kitchen renovation, these powerful machines will help you do so.
