Compact, factory-assembled filter and pressure regulator engineered for micro‑irrigation systems. The Hunter HFR-100-075-25 combines a polypropylene filter body with a reliable fixed 25 PSI regulator, a 150-mesh (100 micron) stainless steel screen and a flush cap to protect emitters and maintain consistent downstream pressure across a wide flow range.

  • Integrated filtration and regulation: Single, space-saving unit that filters debris and reduces pressure to 25 PSI at the outlet.
  • Flow capacity: Operates across 0.5–15 GPM (30–900 GPH), suitable for most drip and micro irrigation runs.
  • Durable construction: Black polypropylene housing with a 150-mesh (100 μm) stainless steel screen for long service life.
  • Operating range: Rated for inlet pressures from 20 to 120 PSI and temperatures up to 120°F (49°C).
  • Connection sizes: 1 in. NPT inlet x 3/4 in. MIPT outlet for easy integration with common irrigation piping.
  • Maintenance: Removable flush cap and screen for quick cleaning; no special tools required for routine service.

Use the HFR-100-075-25 ahead of drip manifolds, zone valves, and low‑flow emitters to reduce clogging and protect downstream components. Ideal for residential and commercial micro‑irrigation, this pre‑assembled kit simplifies installation and service by delivering reliable filtration and fixed pressure control in a single compact unit. Refer to the technical spec sheet for dimensional drawings, UPC, and installation notes.
