Our unique size and service allows us to produce low volumes at competitive prices with no minimum order quantity, from 10 to 1000 we can produce free samples for you in just a few short days.

To ensure the performance of our filters we use the latest injection moulding technology to form the connections, over moulding to seal the housing.

State of the art ultrasonic welding means our media is secured without the use of chemicals. The technology also means substances enter the media and avoid costly by pass.



As an OEM provider our tampo printing technology means we can print logos and information straight onto the filters, ensuring your branding is consistent throughout product ranges.

Our etching technology prints lot numbers recording traceability across our process controls.
