 Product Description




These (K-cup coffee filter) style retainers hold 100% biodegradable EZ-cup disposable paper filter elements and make solvent recovery cleaner and more economical than buying expensive Wix 24003 or Napa 4003 replacement filters for your solvent recovery system. They are CNC machined form T6061 aluminum and held to the closest tolerances so that five pieces can be stacked inside a wix tube and be captured tightly by our end caps with no rattle. (End Caps and outside tube are not included in this kit)

This Kit is for 5 pieces of part # (24003KCFE1) filter element retainer with no spacers.

A kit with 2 spacers and 3 retainers is also available Click Here for more info.

Parts may also be purchased individually so you can stack them how ever you want. Click Here for more info.
