Checking the compressed air regulator

NOTICE

Damaging of the machine when compressed air is contaminated

Compressed air that does not fulfill the guidelines for purity according to ISO 8573-1 can damage the machine.

  • Check the water separator of the compressed air regulator daily for contamination.
  • Never use the machine if there is water, oil or solid particles in the water separator.

Checking the water separator for condensate

Condensate in the separator usually points to compressed air not being dry enough.

  1. Check if water, oil or solid particles piled up in the water separator.
  2. If this is the case, switch the machine off immediately and proceed as follows.
  3. Disconnect the machine from the compressed air supply.
  4. Check the compressed air supply and make sure that the compressed air fulfills the requirements for air purity according to ISO 8573-1. Do not use the machine until the compressed air fulfills this requirement.
  5. Drain the water separator by turning the discharge screw counterclockwise.
    • The condensate is blown out downwards under pressure.
  6. Close the discharge screw again by turning it clockwise.

 

Exchanging / cleaning the contaminated filter cartridge

You have to clean or exchange the filter cartridge in the water separator in case of strong contamination.

A strongly contaminated cartridge can lead to a pressure loss.

If the compressed air fulfills the requirements for air purity according to ISO 8573-1, the filter cartridge usually does not have to be changed.

  • If the filter cartridge is contaminated, check the purity of your compressed air.

You exchange or clean the filter cartridge as follows:

  1. Disconnect the machine from the compressed air supply.

  2. If the bowl of the water separator has a release:

    To remove the bowl of the water separator, do the following:

    1. Press the release and turn the bowl counterclockwise as far as you can.

    2. Remove the bowl from the housing.

    3. Pull out the filter cartridge and clean it if necessary.

  3. If the bowl of the water separator does not have a release: Rotate the bowl counterclockwise out of the housing.
  4. Unscrew the filter screw below the filter cartridge.
  5. Pull out the filter cartridge and clean it if necessary.

    6. A new filter cartridge is available as spare part from customer service.

  6. Insert the new or cleaned filter cartridge and reassemble the water separator. If applicable: When doing this, insert the release into the recess on the housing and turn the bowl until it snaps into place.
