Plenum Fan 13 1/2 in Wheel Diameter

This Dayton plenum fan features a 13 1/2 inch backward-curved aluminum wheel designed for belt-drive installations. It is intended for HVAC professionals and facility managers who need to move air through ducted systems. The unit arrives unassembled without a drive package, so the installer must supply the motor, sheaves and belts to complete the assembly.

Airflow Range 695 to 2, 233 cfm

The fan delivers a minimum airflow of 695 cfm and a maximum of 2, 233 cfm at up to 1 1/2 in wc static pressure. This capacity suits medium-sized commercial air-handling applications such as supply or return plenums. Performance drops off when system resistance exceeds the rated static pressure or when the required flow falls below the minimum threshold.

150 Degrees F Inlet Temperature Limit

Ball bearings and a galvanized frame allow continuous operation with inlet air temperatures up to 150 degrees Fahrenheit. The fan runs at a maximum speed of 1, 940 RPM, producing typical belt-drive noise levels that vary with motor selection and duct design. Power draw depends entirely on the external motor chosen by the installer.

Questions about this item

Will the 13 1/2 in wheel and 18 in rough opening fit my existing ductwork?

The wheel is 13 1/2 in diameter and the rough opening is 18 in square; measure your duct to confirm it matches these dimensions.

How do I verify the fan runs at the rated 1,940 RPM after assembly?

Use a tachometer on the 1 in shaft once the motor and belts are installed; the reading should reach 1,940 RPM at full speed.

What components come in the box and what must I supply?

The box contains the unassembled fan with aluminum wheel, galvanized frame and ball bearings; you must buy the motor, belts, pulleys and mounting hardware separately.
