Virtually every home has a room or section that is not as comfortable due to being too hot or too cool. To solve this problem, many homeowners turn to supplemental heaters or air conditioners that can be costly to purchase and operate. There is a cost-effective alternative using inexpensive, unobtrusive Tjernlund brand fans designed to boost conditioned air flow to trouble spots while minimizing operating costs. Tjernlund Products, a leading manufacturer of ventilation products, offers four different types of fans:
(1) Original Duct Booster® Fans are installed in cutout slots in round or rectangular supply ducts to increase air flow to specific rooms.
(2) In line Duct Booster Fans are installed within warm or cold air duct runs to increase airflow.
(3) Register Booster Fans replace existing registers to draw additional air at the point it enters the room.
(4) Transfer Fans, installed in a common wall or floor, move conditioned air from one room or level to an adjoining room or level.
Tjernlund’s Original Duct Booster fans, available in a variety of capacities, feature a motor outside of airstream for extended service life and quiet operation. They are rated for temps up to 200 degrees. Fans are controlled with duct airstat for automatic operation with any forced air system.
In line Duct Booster fans, also available in many capacities to fit various duct diameters, have 24-gauge galvanized steel housings with ribbed duct stops, crimped leading ends and electrical junction boxes. Models are available with 6’ power cords and automatically operate in tandem with a central blower. Other models use a duct airstat to automatically operate.
Register booster fans are used when there is no access to forced air supply ducts. Installation is simple: Remove the existing register, drop the booster fan into the boot opening and cover with the included floor grille. Fans come with a with 6’ power cord and built-in on/off switch. Register fans can operate continuously or can be controlled by an optional speed control and wireless remote.
Tjernlund offers two types of AirShare transfer fans (Room-to-Room and Level-to-Level systems) for homes with forced air, split system, window air conditioners, space heaters or wood stoves.
Room-to-Room fans are installed within interior wall cavities to move air from one room to an adjacent room.
Level-to-Level fans are installed between floor or ceiling joists to circulate air from a lower to upper level or visa versa. All models include powder-coated white intake grille and supply diffuser.
