Description

Rooms at the end of a long duct run often stay stuffy in summer and chilly in winter because back pressure starves them of air. These fans sit inside the duct and push air the rest of the way, so it reaches the registers that need it.

 

Key Features and Benefits of the Suncourt Inductor Corded In-Line Duct Fans

  • Boosted Airflow: Moves 65 to 300 CFM in free air and 80 to 650 CFM boosted, so distant rooms finally get their share of conditioned air.
  • Thermal Protection: A Class B motor with thermal cutoff protection shuts the fan down before it overheats, which matters when it's sealed out of sight inside your ductwork.
  • Any-Angle Installation: Installs at any angle in rigid or flexible round duct, so you can place the fan wherever your existing duct run has room.
  • Plug-In Power: The 120-volt corded design plugs into a standard outlet using the included 6-foot power cord, so you skip hardwiring.
  • Manual Controls: Operation is manual at a single speed unless paired with a compatible Suncourt VS100 or VS200 variable speed control.
  • Polycarbonate Blades: Polycarbonate fan blades on models DB204C, DB205C, DB206C, and DB208C are plastic rather than metal. The 10-inch model DB210C has aluminum fan blades.
  • Wide Operating Range: Rated for 40 to 140 degrees Fahrenheit, so the same fan handles warm furnace air in winter and cool air conditioning supply in summer.
  • Sound Levels: Rated between 2.2 and 3.0 sones depending on size, so you hear a steady, low hum rather than an intrusive fan noise.
  • Certified Safety: MET listed to UL 1995 and CSA standards, confirming the fan meets recognized North American safety requirements for heating and cooling equipment.
  • Compact Housing: Each housing matches its duct diameter in width and height and runs 6 or 8 inches deep, so the fan fits in tight joist bays and attic runs.
  • Made in USA: Engineered and assembled in the USA and backed by a limited warranty covering your first year of operation.

Choose Your Duct Diameter

The Inductor line comes in 5 duct diameters (4, 5, 6, 8, and 10 inches), so you can match the fan to the round ducting in your system.

  • 4-Inch Model: The smallest Inductor moves 65 CFM in free air and up to 80 CFM boosted on just 30 watts and 0.30 amperes, which suits a short branch duct feeding one small room. It weighs 1.45 pounds, so it's easy to support in a narrow duct run. Part number DB204C.
  • 5-Inch Model: This model raises output to 75 CFM free air and 130 CFM boosted while drawing 30 watts and 0.35 amperes, giving a modest bedroom or office a noticeable lift. It weighs 1.55 pounds. Part number DB205C.
  • 6-Inch Model: It pushes 160 CFM free air and up to 250 CFM boosted on the same 30-watt, 0.35-ampere draw, so you get much more airflow without higher running costs. It weighs 2.05 pounds. Part number DB206C.
  • 8-Inch Model: Rated for 210 CFM free air and 500 CFM boosted at 55 watts and 0.70 amperes, this model moves more air than the 6-inch model for rooms that need a bigger boost. It weighs 3.1 pounds. Part number DB208C.
  • 10-Inch Model: The largest size moves 300 CFM free air, and up to 650 CFM boosted at 120 watts and 1.50 amperes, the most airflow in the line. Its aluminum blade stands up to that higher output, and it weighs 4.3 pounds. Part number DB210C.

Note: For variable speed operation, a Suncourt VS100 or VS200 variable speed control is required.

Sylvane's Expert Take

If you have one bedroom or bonus room that runs hotter or colder than the rest of your home, try a Suncourt Inductor in that room's duct before you rebalance the whole system. Match the fan to the duct diameter you already have. The 4 to 6-inch models handle single-room branches, while the 8 and 10-inch models suit larger runs. Thermal cutoff protection matters most because the fan works unseen inside your ductwork, and it's an easy way to finally even out the temperature in that difficult room.

    I need a second fan of this capacity, but it has to be quiet

    Ceiling exhaust fan. Somewhat noisy, but does move the air.
