Hunter Industries HFR-075-40 Pressure Regulating Filter 40 Psi

Product Description

The HUNTER INDUSTRIES HFR-075-40 is a 3/4-inch pressure regulating filter designed for irrigation and landscape water distribution systems. It combines inline filtration with downstream pressure regulation, delivering a fixed 40 psi output to protect drip emitters, micro-spray heads, and low-flow distribution lines from pressure spikes and debris. The unit installs at the zone valve outlet or at the head of a drip lateral, reducing the need for separate filter and pressure regulator components. Licensed irrigation technicians and landscape contractors are the primary installers.

This filter-regulator is suited for residential and light commercial irrigation applications where consistent, regulated pressure is critical for uniform water distribution. It is commonly installed at the beginning of drip irrigation zones or low-volume micro-irrigation laterals where both filtration and pressure reduction are required in a single compact assembly. The 3/4-inch connection size fits standard Schedule 40 PVC and polyethylene mainline fittings common in irrigation design.

Key Features

• Integrated pressure regulation holds downstream pressure at 40 psi
• 3/4-inch connection size for direct inline installation
• Combined filter and regulator reduces component count and install time
• Designed for low-volume and drip irrigation zone protection
• Compact form factor suits tight valve box installations

Compatibility

Designed as an OEM-style inline replacement for 3/4-inch pressure regulating filter assemblies used in residential and light commercial drip and micro-irrigation systems.

Installation Notes

Installation is typically performed by a licensed irrigator or landscape contractor. Shut off the water supply and depressurize the line before disassembly or installation. Observe flow direction markings on the body and install accordingly. Follow local plumbing and irrigation codes for backflow prevention requirements upstream of this device.
