High quality material: : The 1/4" filter regulator is made of high quality aluminum and plastic, which is stronger and more durable than ordinary models. Ingenious design: : the humidity compressor of the dehumidifier lubricates the air pressure of the main channel to the pressure value required by the equipment, which is not affected by the fluctuation of the inlet pressure and flow rate, and always maintains stable outlet pressure. Easy to use: : The air compressor trap with lubricating cup has instrument display data, which is easy to read. Lightweight, small in size, easy to install and maintain. Advantages: : Filtered regulators can remove solid particles and condensate with compressed air and properly prepare the air for a variety of compressed air tools and equipment. [Wide range of uses]: oil-water separation lubricators can be used in air compressors, pneumatic tools, gas connection devices, and high-efficiency filtration of moisture and air in the air.
