521259 Suburban FRONT BLOWER HOUSING

SFVH-20/25/30/35 Q/FQ (ONE PIECE HOUSING)

The Suburban 521259 Front Blower Housing is the OEM one‑piece molded housing used on all SFVH‑series high‑static, high‑output furnaces. This housing supports the combustion blower and room‑air blower alignment, ensuring proper airflow, motor positioning, and noise reduction. The one‑piece design is specific to the SFVH Q/FQ furnaces and is not interchangeable with the multi‑piece housings used on standard SF‑series units.

This housing is commonly replaced when the original becomes heat‑warped, cracked, or damaged during motor removal.
