Pro-source CED4640M Direct Drive Blower Fan 1/2 Hp

Product Description

The PRO-SOURCE CED4640M is a direct drive blower fan designed for residential HVAC air handling applications. Running on 120 volts single-phase power, this unit delivers 1/2 horsepower output across three selectable speeds, giving technicians flexibility to match airflow to system demand. At low speed, the fan moves 2,500 CFM. The molded ABS plastic housing and blade construction keep weight manageable while resisting moisture and corrosion common in air handler environments. With a three-conductor plug and straightforward wiring, this blower fits neatly into typical furnace or air handler replacement workflows handled by licensed HVAC technicians.

This blower fan is suited for residential forced-air systems where the original direct drive unit has failed or is being upgraded. The three-speed motor allows the installer to select the appropriate tap for heating, cooling, or continuous fan operation as the system requires. At 21.26 inches tall, 20.08 inches wide, and 20.87 inches in length, verify cabinet clearances before installation. The 9-3/8 inch blade length is a key measurement when cross-referencing OEM replacement compatibility.

Installation Notes

Installation should be performed by a licensed HVAC technician in accordance with local mechanical codes and the equipment manufacturer's service documentation. Disconnect and lock out all electrical power to the air handler or furnace before removing the existing blower assembly. Confirm cabinet dimensions and blade clearance match the replacement unit prior to mounting. Verify speed tap wiring connections against the equipment wiring diagram before restoring power.
