The F72 in-line electronic air cleaner removes airborne particles such as tobacco smoke, dust, cooking smoke, soot, pollen, bacteria and cigarette smoke from the circulating air in commercial kitchens and restaurants. The F72 is mounted in the return air duct of a forced air system. One or two electronic cells within the filtration system remove airborne contaminants with up to 99 percent efficiency. Rooftop or interior mounted, the F72 is modular and can be configured for an infinite capacity. Outdoor, insulated enclosures available. Replacement parts for our commercial kitchen air cleaning units are also available.
