UNI AIR FILTER BRP ATV NU-8706ST

MFG Part Number: NU-8706ST

The principal of how foam air filters work is simple: "Open Cell" polyurethane foam is wetted with specially developed filter oil

The "sticky" filter oil is suspended in the path of the dirty air on the strands of the web-like cell structure of the foam

This makes it impossible for the dirt to pass through the strands

As the outer strands become loaded with dirt particles, the wetted strands down stream start trapping dirt, allowing the entire thickness to be utilized

This prevents surface loading or air restriction for 80% of the surface life of the air filter element

When the filter is sufficiently dirty it can be easily washed, re-oiled and re-used
