High Quality Materials: Made of high quality aluminum and plastic, the air filter regulator is stronger than ordinary regulators and more durable. Function of Well: The water separator compressor humidity can remove solid particles and condensate with compressed air and prepare the air properly for many types of compressed air tools and equipment. Excellent Design: The oil water filter compressor adjusts the main channel air pressure to the pressure value required by the device, regardless of the size of the inlet pressure and flow fluctuations, always maintain a stable outlet pressure. < p>Easy to Use: The filter oil water separator has a gauge to display the data and it is easy to read. Light weight, small size, easy installation and maintenance. Widely Used: The oil water filter compressor can be used in air compressors, pneumatic tools, gas connection installation, filtration effective air humidity etc.
