ARO F35121-300 Pneumatic Oil Filter NPT 1/4 Inch Inlet Outlet 150 PSI 0.3µm

The ARO F35121-300 Pneumatic Oil Filter provides reliable oil filtration for compressed-air lines, with a 1/4 inch NPT inlet and outlet and a 0.3 µm filtration rating. It removes oil carryover from a compressed-air supply to protect downstream components in automated and industrial pneumatic systems. Rated for up to 150 psi, this filter connects to standard NPT piping, enabling straightforward integration into existing air circuits. By targeting fine oil contaminants at the point of use, it helps extend the life of actuators, valves, and pneumatic tools and reduces maintenance intervals. The F35121-300 designation identifies this specific ARO filter model for procurement and maintenance records, making it clear which component is installed in your line. Commonly used in manufacturing and service environments where compressed air powers tools and actuators, this filter helps maintain performance by limiting oil carryover downstream.
