Duct Booster Fan Tjernlund Model DB2

The DB-2 DUCT BOOSTER is designed to increase the flow of heated air in warm air heating systems, or cooled air in central air conditioning systems. Its size and design limits its use to branch ducts serving individual rooms, not the main supply or “truck line” duct. The DUCT BOOSTER can be mounted on round or flat ducts. It is frequently installed on a warm air duct of a gravity warm air furnace to provide heating for a basement area. Duct Booster Fans can be installed in existing supply ducts to boost air flow into hard-to-heat or cool rooms or they are the efficient, economical way to exhaust unwanted heat, humidity, odors or other air-borne contaminates.

Features:

  • For boosting air flow in heating or air conditioning ducts, or for powered ambient air intake or exhaust
  • Easy installation in both round and rectangular ducts. Can be installed in a section of metal duct and spliced into a section of flex duct
  • Installs in round metal ducts from 5” - 8” diameter or rectangular ducts as shallow as 3 1/4”
  • Maximum ambient room temp. 100° F
  • Maximum duct air temp. 200° F
  • Rated for heated and cooled air
  • Heavy gauge housing
  • Stronger motor than the competition
