ARO F25221-210 Pneumatic Filter Regulator One Quarter In NPT

ARO F25221-210 Pneumatic Filter Regulator is a compact 1/4" NPT module that combines air filtration and downstream pressure regulation for compressed-air systems. Part of the ARO Module/Air 2000 family, this unit accepts a 1/4" NPT inlet and outlet and uses a 40-micron filtration element to remove particulates before regulation, helping protect downstream actuators, cylinders, and tools. It supports a maximum system pressure of 175 psi and is rated for temperatures up to 175°F (79°C), making it suitable for typical shop-air and automation environments. By integrating a filter and regulator in a single unit, it simplifies plumbing and helps maintain consistent downstream air quality and pressure in automated lines. The F25221-210 designation identifies this 1/4" NPT variant within the series, which includes other drain configurations and porting options to suit different installation needs.
