The Rain Bird PRB100 is a commercial-grade 1-inch basket filter with an integrated 40 PSI pressure regulator. Designed for low-volume drip and micro-irrigation zones, it combines reliable pressure control with robust filtration to protect emitters and simplify maintenance.

  • Flow range: 5 to 20 GPM (diagnostic flow 3.0–20 GPM) for medium-flow applications.
  • Pressure: Inlet 15–150 PSI; regulating pressure fixed at 40 PSI (2.7 bar).
  • Filtration: Stainless-steel mesh screen (commonly supplied as 150 or 200 mesh / ~75–100 microns); replacement screens available for finer or coarser filtration.
  • Durability & materials: Glass-filled nylon body with stainless-steel screening and threaded top with O-ring for tool-free access.
  • Service features: “No-spill” cleanup prevents debris falling back into the line; quick basket access makes cleaning fast.
  • Operating limits: Rated to 150°F (66°C); inline design reduces fittings and leak points.

Use the PRB100 where stable downstream pressure and emitter protection are essential — commercial landscaping, drip zones, and light-commercial control kits. For installations with emission points more than 5 feet above the filter, install a check valve downstream of the regulator. Replacement screens and caps are available (refer to product documents and Rain Bird part numbers for the correct mesh size).

Frequently Asked Questions

What pressure does the PRB100 regulate to?
The PRB100 regulates downstream pressure to 40 PSI (2.7 bar), protecting emitters and preventing blowouts.
How fine is the filter mesh and can I change it?
The unit ships with a stainless-steel mesh screen (commonly 150–200 mesh). Replacement screens in different mesh sizes are available.
Will this unit work if emitters are installed above the filter?
Yes, but if emitters are more than 5 feet above the filter install a downstream check valve to prevent siphoning.
