Tjernlund Automatic 6" Duct Booster Fan with Cord - EF-6AUTO

The EF-AUTO Series Duct BoosterŪ fans are designed to increase the flow of heated air in warm air heating systems or cooled air in central air conditioning systems. The EF-AUTO  series include a 115 VAC power cord and built-in Pressure Response Control so they can be automatically operated when the forced air system fan/blower is running.

The EF-AUTO Series are controlled by an electronic Pressure Response Control (PRC). The PRC control senses positive pressure in the duct work and turns the EF-AUTO Fan on when the forced air system fan/blower is running. The EF-AUTO fan will continue to run after the forced air system fan/blower shuts off to continue to distribute warm or cool air to the room. NOTE: The PRC may momentarily shut the EF-AUTO unit off while the forced air system fan/blower is running while it does a pressure check to determine if the EF-AUTO should continue to run.
