Application

Air curtains with EC/DC single inlet Centrifugal Blower are used to protect the heated space from getting cold air from the outside through the open gate and door openings.

principle,which relies on such equipment is simple enough.inside the unit is installed high-power fan,which supplies a constant flow of air,thus preventing the penetration of cold,and blocks air from leaking out of the room.usually,the air curtain is installed above the doorway or gate.
