Source1 2631136000 Fan Propeller 4 Blade 18 Inches 1/2 Inch Bore 23 Degree Pitch Clockwise

Product Description

The SOURCE1 2631136000 is a 4-blade propeller fan designed for use in heat pump systems and HVAC equipment requiring reliable, consistent airflow. This OEM replacement fan propeller measures 18 inches in diameter and features a 1/2 inch bore with a 23-degree blade pitch. The clockwise rotation direction ensures proper air movement through the condenser or evaporator section of compatible units. Manufactured to original equipment specifications, this fan blade is engineered to fit and perform exactly as the factory part it replaces, helping technicians maintain equipment warranty coverage during service calls. The SOURCE1 2631136000 is a direct replacement for units including E1FB018A06A, E1FB012S06A, and E1FB012A06A models, among others. HVAC technicians working on York and compatible heat pump equipment will find this propeller fan meets OEM dimensional and performance standards. The 4-blade design balances airflow efficiency with quiet operation, reducing unnecessary energy consumption and preventing air stagnation around the heat exchanger. Proper blade pitch is critical in propeller fan performance. The 23-degree pitch on this fan moves an effective volume of air at appropriate motor load, helping the system maintain rated efficiency. Using the correct OEM fan blade also reduces vibration and noise compared to aftermarket alternatives that may not match the original balance specifications. Whether replacing a cracked blade, a damaged hub, or a fan that has gone out of balance over time, this direct-fit replacement simplifies the repair process. Technicians can install with confidence knowing the bore size, diameter, rotation, and pitch all match original equipment requirements. This propeller fan is a standard component in heat pump parts inventory for residential and light commercial HVAC service.
