Direct Gas

The Direct Gas Fired model provides the most heat of any air curtain in the Powered Aire product line. With the Direct Fired air curtain, the intake air goes directly through the flame prior to being discharged. This air curtain will provide up to a 105 ̊F instant temperature rise at the threshold. Not only will this model prevent cold air from infiltrating the opening, it will help keep door hinges from freezing, keep the floor dry, help keep employees comfortable and promote safety and productivity.
