Designed for use in residential applications where homeowners’ rooms are uncomfortably hot or cold because their forced-air furnace/air conditioner blower cannot provide adequate velocity, the Duct Booster® register booster fans can now increase comfort.

RB-Series Register Booster fans are designed to increase the flow of heated air in warm air heating systems or cooled air in central air conditioning systems. These ultra quiet register booster fans are ideal when the duct run serving the room is not accessible to install a standard Tjernlund In-Line Duct Booster fan. Requiring only about 5 per year to operate the RB-Series includes power cord and built-in on/off switch. Plugs into standard 115 VAC outlet.
