Mars Air Doors offers an excellent choice of commercial grade air curtains designed to greatly enhance your work environment. A wide choice of units is offered for diverse locations such as retail stores and office buildings, restaurants, drive-up windows, hospitals and convalescent homes, concession stands, refrigerated cold storage, clean rooms, and more.
Various air flow choices and sizes enable you to tailor your selection to your specific requirements. These quality-built units help to reduce windborne dust, pollen, smoke, flying insects, and maintain desired interior temperatures. This creates greater worker productivity through improved working conditions, higher employee morale, less employee downtime from airborne infections and allergies, and adherence to many industry requirements and standards.
The units feature high tensile strength PolyMars™ housings that are impervious to all types of chemical and climatic exposures. The PolyMars material not only maintains its attractive appearance, but also deadens operating sound levels to provide the quietest air curtain in the industry.
All Mars Air Curtains have a self-contained one piece housing, and are fire retardant and corrosion proof.
For your added convenience, Mars offers C, CH, and CHS Series air curtains, which are similar in design and construction except for differences in outlet air flow and motor capacity. All of these commercial grade air curtains provide dependable climate, insect and energy control for a variety of settings, from receiving doors and cold storage doors, to entrances for office buildings, department stores and supermarkets. Depending upon the height of your doorway and the air flow required, one of these three models will provide a solid solution.
The C Model, for doors typically up to 8' high, designed to mount over customer entrances, creates a mild curtain of air undetected by customers walking through the doorway. It acts as a continual barrier against outside climate to maintain the desired interior temperature. The unit also prevents loss of refrigerated air and reduces humidity or ice buildup, in coolers and freezers.
The CH for doors to 10' high and CHS for doors to 12' high Models produce a greater velocity of air flow. Recommended for above average insect conditions, the CH and CHS Models are highly effective in large markets, restaurants, hospitals, food processing plants and schools.
All three models are offered in heated and unheated versions. Adjustable vanes at the outlet nozzle make it possible to direct the air where needed most and to compensate for possible draft conditions through open doorways. These easy-to-install units create productive environments.
