Filter housing with 300 psi pressure relief valve and replaceable element. This filter kit is compatible with ALL Gen 3 and Gen 3+ units. 

Our filter manufacturer has discontinued sales of the black filter housing in favor of this new design that our testing predicts will be sturdier.  The new housing contains a single O-ring rather than two O-rings, making the gray canister bottom incompatible with the black top.

Installed between unit and nozzle circuit.   Tubing from unit connected to port on pressure relief valve.  Tubing from port marked “OUT” feeds nozzle circuit.  Replace filter element annually or more frequently.  READ AND FOLLOW INSTALLATION INSTRUCTIONS CAREFULLY!
