Speedaire 4ZL55 Oil Removal Filter

Speedaire 4ZL55 Pneumatic Oil Filter is a coalescing oil removal filter for compressed-air systems that uses 3/4 in NPT inlet and outlet fittings (female) and delivers clean air by removing oil aerosols, oil vapor, particulates, and water down to 0.01 micron. It handles up to 60 CFM at a maximum of 150 psi, weighing about 7 oz, and features a polycarbonate drain bowl with a manual drain for straightforward maintenance. The unit's compact footprint is roughly 3 1/8 in wide by 11 3/8 in tall and supports left-to-right airflow, with a maximum operating temperature of 125°F. As a Speedaire standard-duty coalescing filter, it is commonly installed on shop-air lines supplying pneumatic tools, spray equipment, and other air-powered devices where oil contamination must be minimized to protect performance and extend component life.
