Can anyone recommend a top notch filter to remove oil from the compressed air lines. The filter will be placed before the machine. We have traps that catch .01 micron oil in the airline but it is still getting through to the machine.
Use an oil free compressor ;). My UK based answer would be: We treat our air at point of use with a desiccant air dryer by Walker Filtration (this unit looks remarkably similar to units by Mark, Beko and others (especially the controller) this dryer unit was supplied with 3 filter modules, a coarse and a fine filter before the unit (XA and X1 models) and an RXA model after it to catch any crap that comes out of the dryer. I don't see a drop of water or oil in the traps located on the machine. So I would guess these filters and rivals equivalents do a fine job.
