Reznor 195666 Ventor Wheel

For service technicians handling Reznor unit heaters, the Reznor 195666 Ventor Wheel is the direct OEM replacement engineered to maintain the critical draft required for safe combustion. This 6-1/4 inch diameter venter wheel features a 1-inch bore size, ensuring a precision fit on the inducer motor shaft to eliminate the vibration and bearing wear often associated with generic alternatives. Specifically designed for use with high-capacity Reznor UDAP, UDAS, UBX, and UDZ series units (200-400k BTU), this wheel provides the exact static pressure needed to purge the heat exchanger and satisfy HVAC pressure switch requirements. Constructed from heavy-duty materials to withstand high-temperature flue gases, the 195666 replaces legacy part number 135980, offering a drop-in solution that restores venter motor efficiency and prevents premature motor failure. When diagnosing a furnace inducer motor making noise, replacing a fouled or unbalanced wheel with this genuine Reznor component is a standard best practice for maintaining equipment longevity and HVAC system airflow.

• OEM Compatibility: Exact replacement for the Reznor 195666 power venter wheel, fitting models UBX, UBZ, UDX, and UDZ 200 through 400.
• Precision Balanced: Minimized vibration protects the inducer motor bearings and reduces operational noise in commercial spaces.
• Direct Fit: 1-inch mounting hole and 6.25" O.D. ensure rapid installation without needing shaft adapters or modifications.
• Optimized Draft: Maintains specific CFM and static pressure to ensure combustion air intake and exhaust safety protocols are met.

How do I know if I need a new venter wheel versus a new motor?
If you hear a rattling or scraping sound but the motor still spins, the 195666 wheel may be loose, unbalanced, or clogged with debris. If the motor hums but fails to rotate, the wheel may be physically seized or the motor itself may have failed.

Is the 195666 compatible with older Reznor series?
Yes, this is the official replacement for the older 135980 part number and is standard for the 200-400 range of UD and UB series heaters.

Can I use a universal blower wheel instead?
Universal wheels often lack the precise balance and temperature rating required for Reznor HVAC equipment. Using a non-OEM wheel can lead to pressure switch trips or internal damage to the heat exchanger due to improper venting.
