Heavy equipment typically operates in dusty, dirty conditions and a generic Quick-Fill tank vent has no means of preventing airborne contamination entering a tank. The Banlaw Filtered Vent comes with a serviceable air filter within the vent cap. This filter protects against particles entering the tank via the vent, and thus entering the fuel system of the equipment. The service life of OEM fuel filters is extended, reducing the risk of blocked filters and equipment downtime.

Fine Filtered Vent

A complete vent assembly with all the key functions integrated into the one product

The integrated Banlaw Ultra-Fine Filtered Vent greatly reduces the unwanted ingress of dust and other particles into the fuel tank via air flow, especially during fuel usage. With modern and up coming diesel engines calling for a low level of particulates in their fuel before performance and engine life is compromised, the Banlaw Ultra-Fine Filtered Vent has been designed fit for purpose.
