A high quality air line filter regulator with built in water trap and if required a lubricator. This unit regulates the air quality and pressure coming from your compressor. Regulates pressure more accurately than the regulators supplied with most small compressors. Better regulation of air pressure gives air tools more consistent performance and is absolutely essential when spraying. Built in filter to remove large particles and grit that cause excessive wear to air tools. Complete with pressure gauge to show output pressure and locking regulator knob helps prevent accidental pressure adjustment. Also features a built in water trap to remove any condensation that may form in the compressors tank. Also features a built in oil lubricator. If required this lubricates air tools down the air line, and provides an oil mist in the air in proper proportion to the consumption. However if you do not require this just do not fill it with oil and it will not lubricate the line. Specifications Maximum pressure 220psi. Maximum operating temperature; 60 degrees. Easy to use drain off valve. Side markings on lubricator show the max oil fill level. 1/4" BSP Fittings. Regulation pressure 0150psi. Maximum air flow; 105cfm. Complete with bracket for wall mounting.
