Remarks Pressure drop at the above air flow is 0.03MPa and less at 0.69Mpa on primary side. Pressure drop at the above air flow is 0.01MPa and less at 0.1Mpa on primary side.

Note: (1)

Auto drain type exhausts drainage at inner pressure of 0.1Mpa or less and closes at 0.1Mpa or more.

But use air compressor of 0.75kW or above since air flow of 90L/min. or above is necessary.
Use manual drain type when air compressor of less than 0.75kW compressor is in use.

  (2)

To filter oil specifically, use 3µm element which absorbs and separates oil particles (AF-106/108 and AF-206B/208B can be equipped as option).

(3) Bowls are made of polycarbonate. Do not use chemicals such as thinner, carbon tetrachloride, alcohol, chloroform, trichloroethylene, acetate, sufuric acid, alkaline water solution directly or in surrounding atmosphere including such chemicals.
(4) Do not use these products when air compressor uses synthetic oil. If done, it can break polycarbonate bowl.
