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.
