CASCADE AIR PURIFIERS were created to control the problem of indoor air pollution such as tobacco smoke, allergy causing pollen and mold spores, common house dust, and a variety of commercial and industrial contaminants. They are available in three models, the 250-D, the 600-D, and the 1200-D, which cover air treatment applications from residential to commercial and industrial. Individual purifiers in the Cascade family service areas from 80 to 1200 square feet.

All CASCADE AIR PURIFIERS share the common features of: "Media-type" filtration - no snapping and popping, no ozone generation, easy care maintenance, plus clean and safe disposables

Versatile features - dual filter intakes, variable speed blowers, fully adjustable diffusers, mounting options, and optional filter medias available to solve most indoor air quality problems.

Attractive design - Genuine oak trim and brushed aluminum trim, contemporary color choices.

The PH Odor Control filter is a rigid box-type filter engineered to provide medium and high-efficiency gaseous contaminant absorbtion. Its construction eliminates the need for retainers and special external wire media supports. A high surface area-to-depth ratio provides the maximum amount of effective filter media in areas of minimum in-line duct space. These carbon-loaded pleated box filters remove airborne molecular contaminates present at level less than one part per million. Also available in header models for side-load accessibility.

MODULAR AIR HANDLING EQUIPMENT - MODULAR SIDE ACCESS FILTER HOUSING - Eliminates "in the room" air cleaners which are unsightly, expensive, noisy and take up valuable space. Our units work above the ceiling in either the existing duct work system, or an easily installed independent flex duct system.

Filter housings and motor-blower modules are separate and combine with various HEPA or carbon modules to form one unit. Or placed in separate locations by a duct they create one of the best Air Handling systems available.
