Air curtain is Not an air conditioner Air curtain is a powerful fan that creates an invisible high speed air barrier over the entrance to isolate the interior and exterior air environment and maintain temperature separation. Awoco Air curtains are a huge energy saving device as they help to prevent the conditioned air escape to exterior, blocking the entry of dust, and smoke. Why choosing Awoco Air Curtains? Awoco high quality product reputation and supreme customer service is a guarantee. Free parts, repair or exchange within warranty. Why magnetic switch is better than plunger switch? The traditional mechanical plunger micro switch has to be installed accurately to trigger the plunger. It might be damaged easily by a door slamming. 120V directly applied on the micro switch will cause sparks built up. However, the magnetic switch installation is very easy as connecting to the dedicated 2 wires. Magnetic switch works easily with any kinds of doors and windows, even the door isn’t closed fully. Where does it serve? Awoco Air Curtains are widely installed at the entrances. Office, home, store, drive-thru window, restaurant front doors.
