5711 Blow Off Valve Filter
GFB’s 5711 foam filter is designed to protect atmosphere-venting BOVs that operate in dirty environments. Manufactured in Australia by Uni Filter for GFB, the 5711 features a foam filter element with internal steel reinforcement to keep the dirt, sand, mud, and other debris out of your BOV!
The large filter area is specifically sized to ensure minimum restriction to the blow off valve operation. Don’t underestimate how much air a BOV dumps in a very short amount of time – the small 25mm breather filters that other brands use significantly strangle the flow capacity of the BOV.
