I was directed to these posts by a few Buggy owners and asked to respond to questions.
The filter selected and pictured is designed for severe duty dirt/sand/off-road applications. The media is specifically engineered to deal with .3 micron dust and the efficiency is significantly higher than any oiled gauze.
Using ISO Fine testing, the R2C filter we're discussing exceeds 99.3% efficiency as compared to 94-95% for the gauze filter with glue (oil).
The restriction curve is much flatter than when using gauze. It's not unusual for an R2C filter to hold 3 times the dust while offering much lower restriction when loaded. The gauze is very poor in terms of the rapid restriction rise when even lightly loaded.
R2C filters are designed for compressed air cleaning from inside-out and are ready to go over and over again. Low restriction, much improved efficiency and dust holding ability, simple maintenance and No Oiling.
Please try one and let me know your thoughts.
