Champion Speedaire 1WD22 Two-Stage Cast Iron Air Compressor Pump

Speedaire 1WD22 is a two-stage, splash-lubricated air compressor pump cast in iron, engineered as a replacement pump for Speedaire compressors. The two-stage layout performs compression in two steps, delivering higher-pressure air and improved efficiency while helping manage heat during extended operation. With all-iron cylinders and related components, the unit is built for durability in busy shop environments and for long service life when used with compatible Speedaire systems. As part of Champion’s Speedaire lineup, the 1WD22 is positioned for refurbishment of older equipment or upgrades where a like-for-like pump replacement is preferred over a full compressor rebuild. This pump’s rugged construction and proven geometry are designed to provide steady airflow and reliable operation in standard workshop air setups, making it a practical choice for maintaining or reviving legacy Speedaire installations.
