Lomanco Power Vent Attic Fan Motor F0510B2944 is a direct-replacement 1/10 HP motor designed to restore ventilation performance in compatible Lomanco power vents.

If your attic ventilator has a worn or noisy motor, this Lomanco replacement motor provides the electrical and mechanical fit many installers need to get a power vent running again. It arrives with a universal mounting hardware kit to replace older flat-plate mountings, accepts an existing flexible conduit, and is built to match the common 5" diameter motor footprint used in many Lomanco 2000-series fans. This product listing summarizes the key specifications, compatibility notes, and practical details installers and homeowners ask about most.

Will this motor fit my Lomanco power vent?

Most Lomanco 2000-series power vents and units using a 5" diameter motor will accept this motor when the mounting style and shaft length match your original. The unit includes a universal mounting kit to adapt to older flat-plate mounts.

• Fits Lomanco 2000 Series and many 5" diameter motor housings.
• Universal mounting kit supplied to replace flat plate with three holes.
• Accepts previous flexible conduit by reattaching the conduit nut.

What are the electrical and speed specifications?

This motor runs on standard residential power and delivers modest torque appropriate for small attic fans and vents. Confirm voltage and amp draw compatibility with your circuit before installing.

• Voltage: 115–120 V, single phase, 60 Hz.
• Current draw: 3.4 amps at 115 V.
• Speed: approximately 1050–1100 RPM; 1/10 horsepower rating.

What are the shaft and mounting details I should check?

Measure your existing motor shaft and mounting arrangement to ensure the replacement will engage the fan blade and fit the bracket. Note that this motor does not use the flat plate sandwiched between laminations present on some older motors.

• Shaft: 1/2" diameter x 1.75" length with a flat on the shaft for secure blade mounting.
• Motor body: 5" diameter; motor length 2 1/4" (excluding shaft).
• Rotation: clockwise when facing the shaft (CW).

Are there related parts or warranties I should consider?

Lomanco offers compatible blades and alternative motors if your installation needs a longer shaft or different mounting. The motor includes a limited manufacture warranty for peace of mind.

• Replacement fan blade reference: part #14393 (sold separately).
• If you require a longer shaft, consider motor #PD144 with a 4" shaft length.
• Manufacturer warranty: 1 year from the date of manufacture.

Who this is for: This replacement motor is aimed at homeowners, roofing and HVAC contractors, and maintenance technicians who need a straightforward swap-in motor for Lomanco 2000-series power vents or similar 5" motor installations. If you value keeping an existing vent housing and conduit, this motor simplifies repairs by supplying a universal mount and a shaft compatible with many fan blades. Measure shaft length and mounting style before ordering to ensure proper fit, and choose motor #PD144 if your installation needs a longer shaft.
