Filter Maintenance
Replace the filter regularly.
In addition, replace the gasket as well when replacing the filter. (See
„
Ordering Parts .)
(1) Make sure that air pressure is not being applied to the pressure regulator, and that
there is no residual pressure in it.
(2) Drain any water or oil from inside the drain bowl. (See
„
Drain .)
(3) Remove the four M5 screws from the drain bowl.
(4) Replace the filter and gasket.
(5) Tighten the four M5 screws of the drain bowl to the specified torque.

parts and that the pressure is adjusted to the specified pressure. This completes the
procedure.

Handling Precautions
• Do not bend or scratch the filter. Do not use a filter that is damaged, etc. Doing
so may result in damage, air leakage, or malfunction.
• The filter may not filter water or oil sufficiently. Any water or oil in the
instrumentation air may result in damage, air leakage, or malfunction.
• Avoid washing and reusing the filter. Doing so makes the filter less functional,
resulting in damage, air leakage, or malfunction.
