The sterilization filter is mainly composed of upper barrel, lower barrel, filter core component, filter core derrick component, instrument and so on. Compressed air containing dust and water enters the container from the inlet of the filter and passes through the tubular core from the outside. Under the combined action of direct interception of the combined filter bed, inertial collision, gravity settlement and other filtration mechanisms, the tiny fog-like particles are further captured and precipitated in the process of penetrating the filter bed. Finally, the separation of gas-liquid and dust particles is realized in the inner layer of gravity sedimentation layer, and the droplets and dust particles are discharged from the sewage outlet.

This series of products elaborately made filter core component, its purification degree is high, the resistance is small, the filter capacity dust quantity is big, the life is long, the overall structure is compact, the operation and maintenance is convenient.
