5.6 Air Purge for Splash-Proof Type
By supplying dry, compressed air into the actuator, it performs dust proof and splash proof (water and
dust) of IP65 *1 .
Instruction below shows how to perform air purge.
Air purge is performed with using the quick joint (O.D. I6) on the rear cover. Supply air from the upper
joint.
The lower quick joint is used as a drain joint (a hole to withdraw water) in the case that water gets inside
the actuator. Connect a I6 air tube and take it to a place where no water or dust gets in to withdraw
water.
1. Actuator Air Pressure … 0.1MPa to 0.2MPa(approx. 1kgf/cm 2 to 2kgf/cm 2 )
2. Air Flow … Approx.20 to 40Nl/min
3. Applied Air … Do not supply air directly from a compressor. Make sure to supply dry compressed air
via an air drier.
Air to supply should not contain compressor oil and should be clean dry air that has
