The precision filter is mainly composed of upper cylinder, lower cylinder, filter element component, filter rod component and instrument. Compressed air containing dust and water enters the container from the filter inlet and passes through the cylindrical core from the outside to the inside. Under the combined action of the direct interception, inertial collision and gravity sedimentation of the combined filter bed, the tiny foggy particles are further intercepted and promoted to condense in the process of passing through the filter bed. Finally, the gas-liquid and dust particles are separated in the inner layer gravity settling layer, and the droplets and dust particles are discharged from the sewage outlet.

This series of products adopt the filter element components carefully manufactured according to the condensation and filtration mechanism, with high purification degree, small resistance, large amount of filter dust, long service life, compact overall structure and convenient operation and maintenance.
