Ingersoll Rand F25231-110 Pneumatic Air Filter

The Ingersoll Rand/ARO F25231-110 is a 3/8" NPT inline pneumatic air filter that provides 40-micron filtration for compressed air at up to 175 psi (12 bar, 1207 kPa), helping protect downstream tools and equipment from particulate contamination. It features a metal bowl with a sight glass and a 6-ounce capacity, a manual drain for straightforward condensate removal, and an airflow rating of up to 100 CFM for mid-range air-lines. The 110 suffix designates the manual-drain variant within the F-Series 3/8" port family, while a related 111 model offers automatic drain. Service and maintenance are supported by available kits that include the O-ring and manual-drain components to simplify field servicing. Suitable applications include filtration for pneumatic tools, cylinders, and actuators in general manufacturing, maintenance shops, and automotive settings, where removing solid particulates from the compressed air stream helps extend component life and maintain consistent performance.
