NBK Parts Direct Replacement 2-Year Warranty NBK Parts 20702-2 -- Broan NuTone Bathroom Vent Fan Blower Wheel, 1/4" Bore, 5-1/2" x 2-1/8"

Stop living with a noisy, underperforming bathroom exhaust fan. This NBK Parts blower wheel (20702-2) is a factory-spec direct replacement for Broan NuTone OEM part 99020276, restoring full airflow to HD50, HD80, 680, and 710-series fans without any modification or adapter.

Restore Your Broan NuTone Fan to Full Performance

When a bathroom exhaust fan starts rattling, slowing down, or moving noticeably less air, the blower wheel is almost always the culprit. Plastic impellers crack, warp, or develop hub wobble over years of continuous use. NBK Parts manufactures this 20702-2 wheel to the same dimensional spec as the original Broan NuTone 99020276, so it drops into the existing motor shaft and housing without guesswork.

The wheel measures 5-1/2" in diameter by 2-1/8" wide and mounts on a 1/4" bore shaft. Rotation is counter-clockwise (CCW) when viewed from the intake side -- matching the original motor direction exactly. Color is black, consistent with OEM appearance.

OEM-Match Dimensions

5-1/2" diameter x 2-1/8" width with 1/4" bore -- identical to the original 99020276 for a drop-in fit.

Wide Model Coverage

Fits 28+ Broan NuTone fan models across the HD50, HD80, 680, 676, 684, and 710-722 series.

Correct CCW Rotation

Counter-clockwise blade pitch matches the original motor direction -- no reverse-airflow issues after install.

2-Year Warranty

Backed by a limited 2-year manufacturer warranty from NBK Parts for peace of mind on the repair.

Installation Overview

Replacing the blower wheel on a Broan NuTone bathroom fan is a straightforward repair for a DIYer comfortable with basic electrical work:

Turn off the circuit breaker for the bathroom fan before starting.
Remove the fan grille and unplug the motor assembly from the housing.
The blower wheel is retained on the motor shaft by a friction fit or small set screw depending on the model -- check your existing wheel before removal.
Slide or press the old wheel off the 1/4" shaft, then install the new 20702-2 in the same position.
Verify the wheel spins freely and is fully seated before reassembling.

Weight note: This blower wheel weighs approximately 0.2 lbs. It ships as a single replacement wheel only -- motor, grille, housing, and mounting hardware are not included.

Maintenance tip: While the housing is open, clear any lint or debris from the duct collar and fan housing. A clogged duct is the second most common cause of poor bathroom fan performance after a worn blower wheel.

Important Information

Verify your existing OEM blower wheel is part number 99020276 before purchasing -- other Broan NuTone wheels use different bore sizes and blade widths.
This wheel is for counter-clockwise (CCW) rotation only. Installing a CCW wheel on a CW motor will reduce airflow significantly.
Disconnect power at the breaker before servicing the fan motor or blower wheel. Do not rely on the wall switch alone.
This is a replacement part only. The motor, fan housing, and grille are sold separately.
Confirm your fan model number against the compatibility list above. Not all Broan NuTone fans use the same blower wheel dimensions.
