FAQ:

Q: Do duct booster fans really work?

A: The duct booster fan boosts the air flow of the room. It spreads the air in the whole room to maintain the same temperature in the room. It is an effective way to control the air of a room. The duct booster fan needs the small amount of energy to do its work.

Q: What is duct booster fan?

A: Our Duct Booster fans are designed to boost air flow in long sections of warm air furnace duct when insufficient heat is attained at a distant register. Duct fans are also effective in aiding the transfer of heat through walls to adjoining rooms when installed in short sections of duct in the wall.

Q: What is an inline booster fan?

A: Booster fans are add-ons that help move air through ducts. While inline duct and register booster fans will not cure underlying defects, they can “boost” air flow, thus increasing the amount of cold and warm air that ultimately makes it to a room.

Q: What is inline cooling fan?

A: An inline cooling fan is essentially exactly what it sounds like – a small fan that sits within the line of existing ductwork. It serves to move air in a desired direction, and can be part of both cooling systems, as well as exhaust systems.
