🛠️ HVAC Depot Pro Tip: FAN04073 and FAN04074 Are Different

Be careful when comparing FAN04074 with FAN04073. They are very similar blades, but their pitch is different:

FAN04073 → 18° Pitch

FAN04074 → 19° Pitch

For FAN04074, verify:

 27.6" Diameter

 3 Blades

 19° Pitch

 CCW Rotation

 1/2" Bore

• Motor RPM

• Motor horsepower

• Motor shaft diameter

• Blade position and shroud clearance

Even a small change in blade pitch can affect airflow and motor loading.
