Air Curtain Machine Sensor

The Air Curtain Machine Sensor switches air curtain units on and off automatically at commercial plus industrial doorways. It removes the need for manual control and saves energy - running the unit only when someone passes. The sensor fits most air curtain models but also links to them without extra hardware. A small LED shows whether the sensor is active or idle. The device is manufactured in India, unused and assembled from components selected for long service. It suits offices, retail outlets, restaurants as well as factory entrances, where it blocks dust and insects or keeps indoor temperatures steady. Two screws and a single cable connect it to the air curtain - installation takes minutes next to no extra switches are required.
