Mars Air Doors and Dynaforce Air Curtains are installed over operational doors and pass-thru windows. Our air curtains will protect your building’s inside environment from windborne dust, dirt, fumes, and flying insects and extreme outside temperature conditions. Not only will our air curtains improve the inside sanitation level of your building, but they will also reduce the operational energy costs necessary to heat and cool it. With a vast variety of products and options, Mars Air Systems can provide you with a complete door-to-door, floor-to-ceiling building air control solution. Our products not only conserve energy, but they also qualify for LEED point credits that will help support your Green Build initiatives. Mars and Dynaforce…Over Every Door.
