[High Pressure Resistance] The filter is made of aviation grade aluminum alloy shell to resist high pressure.  

[Centrifugal Filtration] The filtration effect is up to 99%. When compressed air enters the oil-water filter, the flow direction and velocity change sharply, and the air flow is first pushed back down by the barrier of the filter, then up, and then up, producing a circular rotation. In this way, water and oil steam are separated from the air under centrifugal and inertial forces and drop op the bottom of the filter.

[Great Choice for Scuba Tanks] The filter can remove impurities, odor, oil and water. It's suitable for filling diving bottles.
