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.

Circular Duct Fan should be reviewed around circular ducts, general exhaust, ventilation planning, mounting conditions, electrical service, controls, and access for installation or service.

Use the visible product photos and model reference image to start the comparison, then confirm release documents before quoting, submittal, certification language, or final project use.

Applications

Applications

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.

Selection boundary

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 review

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

Parameter reading

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.

Start with the visible model cards above, then collect the few site conditions that change equipment fit before requesting final model documents.

  • 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.
