  • Excellent filter
Size: 1/2" NPT, Auto Drain Style: 3 Stage
Excellent 3 way filter..... it filters a lot of the water out of the air, the dessicant bead last a couple uses if you are spraying small part but for a whole car I would probably change them with every stage, after primer, after base & after clear....also good to have the spare filters and dessicsnt beads available to buy from the nanpu store if you need them ... show more

  • Good filters for the money
Size: 3/4" NPT, Auto Drain Style: 4 Stage(+Dryer)
Good working filters. As long as you space it 20-30’ away from your compressor you won’t have any condensation issues. Only thing was I needed to go to hardware store to get proper adapters from and to my air lines.

  • Auto bleed is complete trash
Size: 1/2" NPT, Auto Drain Style: 4 Stage(+Dryer)
Auto drain bleeds are so badly pressure can’t build. I’d highly recommend manual bleed. I ended up having to tap and install a 1/4” NPT valve just to use compressed air in my shop.
