Circular Duct Fan Series

Ventilation Fan

Start here when the project needs ventilation fan for circular duct runs or metal-housing fan selection. Confirm dimensions, voltage, access, controls, and current model documents before selecting an exact model.

Circular Duct Fan Series

Circular Duct Fan

Circular duct fan for round-duct runs where metal housing, outer-rotor motor details, size, and fan curve need coordinated review.

Applications and build notes

Typical uses

  • Circular ducts
  • General exhaust
  • Ventilation planning

Build notes

  • 4/5/6/8/10/12 inch size range
  • Full metal housing
  • Outer-rotor motor details for stronger motor review
  • Round-duct mounting should be checked against pressure and access

Applications and installation

For fan model documents, prepare room type, target CFM or ACH, duct sketch, approximate equivalent length, voltage, control expectation, mounting location, and service-access constraints.

Typical uses

Review bathrooms, storage rooms, light-commercial rooms, support spaces, and ducted ventilation paths by required CFM, duct length, fittings, discharge location, and sound sensitivity.

Product fit

Check this series when a ducted fan path is appropriate. Move to cabinet or utility fan selection when higher pressure, larger service access, enclosure needs, or a different fan construction is driving the decision.

Installation

Confirm duct diameter, equivalent length, elbows, backdraft protection, service clearance, mounting orientation, and wiring or speed-control expectations before selecting a fan body.

Parameters

Read CFM together with static pressure, sound, motor type, power input, and duct size. A free-air CFM value is only a starting point when the installed duct path adds resistance.

Sizing inputs

Ducted systems need a fan selected around CFM, duct path, pressure loss, noise sensitivity, and service access.

  • Gather target CFM, duct diameter, duct length, elbows, filters, and expected static pressure.
  • Avoid selecting by duct diameter alone.
  • Confirm noise, service access, and controls before model selection.
  • Airflow CFM
  • Static pressure
  • Duct size
  • Motor type
  • Voltage
  • Sound rating where available
