In-Line Duct Fan for General Ventilation

This Soler & Palau mixed-flow duct fan delivers 538 cfm at .000 in SP for general-purpose air movement. It operates on 120V AC single-phase power with a 184 W motor rated IP44. A mounting bracket is included for straightforward installation in 8 in ducting.

Suited for Straightforward Exhaust or Supply Runs

The unit suits installers who need a compact in-line fan with two-speed control for basic ventilation. It is not intended for ducted systems that develop measurable static pressure or for environments exceeding 140 Degrees F inlet temperature. Buyers needing variable speed control beyond the two fixed speeds should look elsewhere.

538 cfm Free-Air Delivery at .000 in SP

This airflow figure defines the fan's capacity in an unrestricted run. If the installation includes filters, elbows or long duct lengths that create resistance, the delivered airflow will be lower than this rating.

Questions about this item

How can I confirm the 538 cfm airflow at .000 in SP after installation?

Measure the airflow at the duct outlet with an anemometer under zero static pressure conditions; the reading should match the rated 538 cfm.

What comes in the box and what must I supply for the 8 in duct connection?

The fan includes a mounting bracket; you must supply the 8 in ductwork, clamps or tape, and a 120V AC power connection.

Which speed setting should I choose for a 140 Degrees F inlet temperature limit?

The unit runs at 800 RPM on its single speed and is speed controllable; select a controller setting that keeps inlet air at or below 140 Degrees F.
