Rainbird Pressure Regulating Filter – Various Sizes

Unique, compact unit that works with all valves to create a simple, efficient control zone. Combines filtration and pressure regulation in one piece for protection of downstream components in a low-volume irrigation system.


  • Reduces the number of components in a control zone, making it smaller and easier to install. More control zones can fit in one valve box!
  • Combination unit comes with 200 mesh (75 micron) stainless steel reduces the number of connections, making installation easier and faster
  • Static RBY filter regulates pressure to a nominal 30 or 40 psi (2.0 or 2.8 bar) – PR RBY Filter Cap has sealing O-ring and unthreads to provide access to the filter element for easy cleaning
  • 30 or 40 psi pressure regulator is integrated into the filter body
  • Robust body and cap are made of glass-filled polypropylene and provide 150 psi (10.3 bar) pressure ratin


Operating Range

  • Flow – ¾” units: 0.20 to 5.0 gpm (0.8 to 18.9 l/m)
    • 1″ units: 3.0 to 15.0 gpm (11.4 to 56.8 l/m)
  • Inlet pressure: 20 to 150 psi (1.4 to 10.3 bar)
  • Regulated pressure: – 3⁄4″ units: 30 psi (2.1 bar)
    • 1″ units: 40 psi (2.8 bar)


  • PRF-075-RBY: ¾” PR RBY Filter
  • PRF-100-RBY: 1″ PR RBY Filter

Replacement Screen

  • RBY-200SSMX (200 mesh stainless steel screen)


Installation Note

  • When installing indoors or on a design where the emission points are more than 5ft. above the Control Zone Kit, you must install a check valve after the pressure regulating filter (RBY or Basket Filter).  The regulator has a permeable white dot that is designed to relieve excess pressure by slowly releasing water droplets.
  • Filter must be installed downstream of any valve; warranty will be void if installed under constant pressure.
