WHY CHOOSE A FUNNELWEB FILTER?

1. The Foam!

Proline Filter pyramid design foam filter doubles surface area for long lasting filter life.


The FunnelWeb’s profile cut foam effectively doubles the filters external surface area, without increasing the filters original size, enabling it to trap and hold far more dust on the outer surface meaning more protection to the engine while maintaining optimal air flow and extending filter service intervals.

The single layer, single density polyurethane foam has the added advantage of ease of cleaning and the ability to maintain its original shape after numerous cleans. As any dirt is spread over a much larger surface area, airflow restriction caused by dirt build up is minimized substantially. Overall, compared with conventional foam filters, FunnelWeb offers more protection from dirt ingestion, has longer service intervals and maintains high airflow rates when dirty.

 

 

2. The Filter Seal!

Proline Filter foam seal

Most FunnelWeb Filter seals are constructed from injection molded urethane for a lasting, precise fit on the filter support frame and the inside of the air box. Foam seals, as fitted to other filter brands, will tend to stretch out of shape after a few cleans resulting in a poor fit to the support frame, possibly affecting the filters sealing ability. Not all filters in our range are suitable for molded seals and the few that are not feature neoprene / nitrile foam gaskets.

3. Refined Development Process

FunnelWeb Filter has been developed over more than five years with the assistance of the motocross and enduro Australian KTM Race Teams. Numerous combinations of foam profiles have been tested in harsh, dusty race conditions and test tracks to come up with the ideal combination. More than 1,500 filters were manufactured, tested and either serviced and reused, or cut open for inspection before any were made available for sale.
