Consider installing an air curtain for a door that swings both ways. The circuit kit will prevent the motor from turning on and off while the door swings.
The air curtain has a 1.5-second shutoff delay to protect the motor when the door is not completely closed.
With the same 1.5-second shutoff delay, the air curtain will remain on to keep dust out if the door is not fully shut.
Transform your air curtain or device to be controlled by a magnetic switch. Suitable for 120VAC 15A max or 1800W max, single phase use only. Not compatible with all air curtain models, please verify before purchase. It's recommended to have a licensed electrical technician install it, as we are not liable for any damage caused by incorrect wiring.
Please note: this kit is patented in the USA and not suitable for remote or circuit-controlled air curtains. It includes two pieces: a circuit board and a magnetic switch.
