What to do if my Alfa Laval Water Filtration System has no flushing?
- T
  Tony PhillipsAug 7, 2025
  If your Alfa Laval Water Filtration System isn't flushing, it could be due to a few reasons: * The flushing valve might be incorrectly mounted on the filter body. To resolve this, dismantle the actuator and turn the valve disc to the correct position. * A failure in the power supply (if electrical) could be the cause. Check the fuses to ensure they are in working order. * If the system is pneumatic, the air supply might have failed. Make sure the air supply is adequate and adjust the air regulator if necessary.

Why Alfa Laval Water Filtration System has poor filtration?
- K
  kathleenwellsAug 17, 2025
  Poor filtration in your Alfa Laval Water Filtration System can occur for several reasons: * The filter basket, rubber profile, or sealing ring might be damaged, requiring repair or replacement. * There might be insufficient back pressure or air trapped in the flushing line. Ensure correct back pressure in the flushing outlet. * If using pneumatic actuators, the flushing valve travelling time might be too short, requiring adjustment. * An external bypass may be open, which needs to be closed.

  Thomas BlackAug 27, 2025
  To address an actuator alarm in your Alfa Laval Water Filtration System, reset the alarm and check the valves, air pressure, limit switch starting and stopping points, and travelling times.
