The in-ceiling mount air curtain protects your door opening without taking away from the overall design of your space, as all internal components are hidden above the ceiling. The unit comes with a 1/2-hp, three-speed motor and fits any ceiling type. The bottom panel provides access to all internal components, including the filter. Heat is available, but optional, in electric, steam, or hot water. An additional Comfort-Plus control package can be added to all heated units. With this option, the air curtain switches from high flow when the door is open to low flow when the door is closed. This feature enables the unit to act as both an air curtain and a cabinet heater by warming your vestibule, while protecting your door opening.
