Air Pressure Regulator, 1/4 Compressor Air Filter, Oil-Water Moisture Filter Lubricator, Pressure Regulator Air Separator for Compressor and Air Tools Filter Features: To lower or maintain air pressure.The air pressure maintaining device performs vacuum compression by injecting air to effectively remove impurities, moisture and pollutants in pneumatic equipment. Composition: The filter cup is transparent, allowing you to accurately and quickly check water and oil conditions.The filter element is made of high quality materials, resistant to strong corrosion and has a long service life.At the same time, you can observe the pressure of the pressure gauge by controlling the pressure button. Easy to use and install: The oil-water separator can effectively control and adjust the pressure dial to provide clean, dry and impurity-free air, ensuring that the compression equipment is not polluted.At the same time, it is light in size, portable, quick to install and maintain. Scope of use: The oil-water separator is widely used for air compressors, pneumatic tools, gas connection installation, effective air moisture filtration. Size: 1/4" Air Compressor Filter Water Separator Regulator. Product Description: 1.Air maintenance device: Constantly compressed air to ensure that the clean air is fully combined with the oil in the oil pipe, and at the same time, it can effectively maintain the service life of the pneumatic device and prevent the entry of impurities.< /p> 2.Filter: Filter the air through the air filter element, which can change the key of impurities. 3.Oil bottle: Add oil to the oil cup from the oil filler screw as shown in the figure.When the product is working, the oil will be combined with the filtered air, and the atomized oil will be sent to the air tool parts and components to lubricate them and make them work properly. Product Specifications : Product Name: 1/4 inch NPT Air Filter Pressure Regulator Body Material: Aluminum Product Notice: 1.Before installing the filter, please pay attention to cleaning the threaded ports and filter accessories to ensure that no impurities enter the air system. 2 .The internal pressure is different from the external pressure at first, and the excess pressure will be discharged, please be patient, after exhausting the excess air, no leakage will occur lucky meet p>Note: The data is all measured manually, please allow 1-3cm error, due to the difference in light and display, there will be a certain color difference, the actual object received shall prevail.
