The Tjernlund Duct Airstat senses positive pressure in a forced air heating and/or cooling system. The single pole, single throw, snap-acting switch is activated by a diaphragm with integral pressure probe inserted directly into the duct or plenum. The Duct Airstat can be used to initiate such auxiliary devices as: Duct Boosters, Electronic Air Cleaners, Electrical Duct Heaters, and Humidifiers. The electrical contacts of the switch are closed upon sensing positive air pressure generated by the blower.
- Air pressure activation switch automatically turns on and off any device, but in particular it turns duct fans on and off based on the furnace and/or air conditioner blower coming on.
- Works with any brand duct fan, including Tjernlund Duct Booster Fans.
- Choose either simple black-to-black, white-to-white wiring (PS1503) or plug-in version (PS1503P).
- Fool-Proof Tech: simple bladder fills and allows power to flow to the fan, so no errors from over engineered circuit boards.
- Manufactured in the USA and backed by a 81-year-old family business.
