Furnace Blower for Lennox Replacement
The FASCO A138 is a direct-drive blower built for furnace applications. It serves as a replacement for Lennox models 7021-8657 and 7021-8825. HVAC technicians and maintenance teams use it to restore airflow in compatible heating systems.
Single-Speed Air Delivery at 3000 RPM
The shaded-pole motor runs at a fixed 3000 RPM on 120 V AC single-phase power, drawing 0.7 A at 60 Hz. It moves air through a 3 7/8 in inlet and a 2 1/8 in outlet. The unit is rated for inlet temperatures up to 400 °F. It does not suit variable-speed controls or applications needing adjustable airflow.
Class B Insulation with Wire-Lead Connection
Motor insulation meets Class B limits for the rated temperature range. Electrical connection is made through wire leads. The blower operates at its single design speed without speed-selection options. Buyers needing speed control or a different voltage should look elsewhere.

Questions about this item
Will the 3 7/8 in inlet and 2 1/8 in outlet match the ducting on my existing Lennox furnace?
The blower is a direct replacement for Lennox models 7021-8657 and 7021-8825, so the inlet and outlet diameters are designed to fit the original duct connections on those units.
How can I confirm the motor is running at the rated 3000 RPM after installation?
With the furnace powered, measure the blower wheel speed using a non-contact tachometer; it should read 3000 RPM at 120V AC, 60 Hz, single phase.
Does the box include a mounting bracket or capacitor, or must I source them separately?
The unit ships as the blower assembly with wire leads only; mounting hardware, capacitor and any gaskets are not included and must be purchased separately.
