My shop air compressor (like most home sized units) came with felt pad for an air filter. I wanted something better.
Here is the felt pad next to the real filter. The felt pad has a plastic housing the real filter has metal.
Here is the inside of the filter.
The felt/plastic unit mounts with a gasket and two bolts. For awhile I pondered how to adapt the new filter assy, til I noticed the compressor was also threaded for 1/2" pipe. Since the new filter has a 1" pipe fitting on it, it was simple matter of a couple pipe fittings to fit them together.
Here is the filter on the compressor.
I have two more filters if anyone wants to do a similar upgrade to their air compressor.
