Wayne Combustion 21854 Blower Wheel

The Wayne Combustion 21854 Blower Wheel is a critical component for maintaining the static pressure and technical efficiency of your forced draft oil burner. This 6 1/4" blower wheel is engineered specifically for use with Wayne E Series burners and Blue Angel models, where precise air-to-fuel ratios are paramount for clean combustion. Featuring a 1/2" bore and a squirrel cage design, this heavy-duty wheel offers a 4" to 4 3/16" width to maximize airflow volume within the industrial burner housing. Professionals often utilize the Wayne 21854 as a direct replacement for legacy part numbers 20289 and 21854-001, ensuring seamless integration with existing 1/2-inch motor shafts. The robust construction is designed to handle high RPMs without vibration, reducing noise levels and preventing the mechanical fatigue often seen in under-engineered aftermarket equivalents. For technicians performing a Wayne burner blower wheel replacement, this OEM-spec part provides the exact tolerances required to restore the pressure atomizing gun's performance to factory standards.

Key Benefits
