This is not the complete filter but it is the replacement element for the the AC393 filter for the RV33 1/4 HP Rotary Vane Compressor and for the RV75 3/4 HP & RV100 Rotary Vane Compressor.
Poor. They sent the wrong filter size. I even called them to confirm, but the ones they sent don't fit. They did this to me the last time as well. I think I will look for a new source.
