Principle of Operation

The Airpel self-cleaning filter (SCF) blends modern technology with simplicity to provide a versatile method of filtering your process fluids. The filter can be set up for fully or semi-automated or manual operation during which the liquid enters the body and flows through the filter element from outside to in. Debris is collected on the outside of the wedge wire or perforated element. Cleaning takes place without interruption to flow by the rotation of the element against fixed scraper blades. The debris accumulated during rotation is deposited into the bottom of the filter body from where it can be periodically discharged either manually or automatically via the drain port. Ideal for processes that require continuous flow, the SCF range is also suitable for use on unmanned sites and with hazardous process fluids.


The High Pressure Range of self cleaning filters is of full cast construction suitable for higher working pressures and temperatures up to 35 barg and 260°C (dependent on seal materials) respectively - even the most demanding requirements can be met. Various levels of automation and element design can be chosen to suit application and installation demands.

Maintaining Process Fluid Quality

Maintaining the product quality by the use of an Airpel Series self cleaning filter, helps to reduce downtime, increase productivity and contain/reclaim unwanted debris to comply with company and environmental legislation

Common industries where product quality is essential:

  • Water treatment
  • Food and beverage
  • Pharmaceutical
  • Paints, inks and varnishes, etc.



The Airpel Series automated self-cleaning filters allows for stand alone, low maintenance processing of liquids. The range can be automated, either electronically or pneumatically, from 32 mm (1.25") and above. The level of automation can be selected from manual cleaning and valve operation to fully automated filters which can be supplied wired and fully tested, requiring only on site connection to the power source and dump valve connection.

Element Design

The wedge wire element is used in 90% of applications and is likely to remain the most commonly used element in the self cleaning filter. However, for certain critical filtration applications a perforated element has been introduced.
The perforated element will prevent 'platelet' shaped debris passing through the element 'letter box' fashion and will make the passage of fibrous debris practically impossible.
