  • Details

    The Tjernlund Duct Airstat is used to automatically activate Duct Booster fans by sensing 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 a factory installed sampling probe inserted directly into the duct 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.

    Additional Information:

    Important: All wiring must comply with applicable codes and ordinances. The Duct Airstat must be mounted in a vertical position. Installations in larger ducts or dead spots" in duct work may not create enough positive pressure impact" to activate the Duct Airstat.
