Rain Bird PRF075RBY 3/4-Inch 30 PSI Pressure-Regulating Filter

Rain Bird PRF075RBY 3/4-Inch 30 PSI Pressure-Regulating Filter

Brand: Rain Bird | SKU: PRF075RBY

Product Overview

Combine drip-zone filtration and pressure regulation with the Rain Bird PRF075RBY, manufacturer PRF-075-RBY. This 3/4-inch RBY filter serves 0.2–5 GPM and targets a nominal 30 psi outlet when adequate inlet pressure is available. It is a separate control-zone component, so pair it with a suitable upstream control valve rather than treating it as an assembled valve kit.

Key Features

• Integrated nominal 30 psi pressure regulator.
• Preassembled 200-mesh stainless steel filter screen.
• Threaded cap with sealing O-ring provides screen access.
• Glass-filled polypropylene body and cap.
• Combines filtration and regulation in one component.

Common Uses

• Low-flow drip zones requiring 200-mesh filtration and a compatible 30 psi supply.
• Replacing a matching 3/4-inch pressure-regulating RBY component.

Technical Specifications

• Model: PRF-075-RBY; merchant SKU: PRF075RBY.
• Connections: 3/4-inch male pipe threads.
• Operating flow: 0.2–5 GPM.
• Inlet pressure operating range: 20–150 psi.
• Nominal regulated outlet: 30 psi, with sufficient inlet pressure for the design flow.
• Screen: 200 mesh (75 micron), stainless steel.
• Replacement screen model: RBY-200SSMX.
• Install downstream of a control valve; not for constant-pressure installation.

Dimensions

• Length: 6 inches.
• Width: 2 inches.
• Height: 4.5 inches.

Compatibility & Installation Notes

Install after a suitable control valve and follow the flow direction. Allow room to unthread the cap and remove the screen. The filter is not intended to remain under constant pressure.

Match the design flow and downstream emitter requirements. A 20 psi supply does not become a 30 psi outlet; the regulator cannot boost pressure. Use the performance chart to account for the available pressure.

Rain Bird calls for a check valve after the regulator where emission points are more than 5 feet above the pressure-regulating filter. Flush the system and service the screen as needed.

This 3/4-inch PRF model differs from the non-regulating inline RBY filter and the 1-inch 40 psi PRF model. A control valve is selected separately.

Frequently Asked Questions

Does this include a control valve?

No. PRF075RBY is the pressure-regulating filter component. Install it downstream of a suitable separately selected control valve.

Can it stay under constant pressure?

No. Rain Bird specifies installation downstream of a control valve and states that the filter is not for constant-pressure use.

What screen and outlet pressure does it provide?

It has a 200-mesh, 75-micron stainless steel screen and a nominal 30 psi regulated outlet, provided sufficient inlet pressure is available at the design flow.

Will it increase a 20 psi supply to 30 psi?

No. It regulates pressure downward and cannot boost a low-pressure supply.

Why Buy from Big Frog Supply?

Choose PRF075RBY for a 0.2–5 GPM zone that needs both fine 200-mesh filtration and a nominal 30 psi outlet. Its 3/4-inch connection and 6-inch length help check replacement fit, while the downstream-of-valve requirement distinguishes it from components intended for continuous mainline pressure.
