RB-Series Register Booster, Duct Booster® Supply & Exhaust Fans
RB-Series Register Booster Fans – For more comfortable rooms!
Save on Energy Bills and 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. Use optional SCP speed control or a remote on/off switch if desired.
