PRB-100 Pressure Regulating Basket Filter

Control Zone Components

Made of durable, glass filled nylon, the Rain Bird PRB-100 combines a commercial-grade filter with a built-in pressure regulator to ensure clean, even water in low-volume irrigation zones.

The unique basket filter design allows the element to be accessed vertically which makes maintenance fast and easy, while ensuring that dirt does not fall back into the filter during cleanup operations.

The PRB-100 comes pre-assembled with a 200 Mesh Stainless Steel filter screen. Replacement stainless screens are also available separately in100 mesh (QKCHK100M), 120 mesh (QKCHK120M) and 200 mesh (QKCHK200M)
