BALDR 4" H-Style Screen Filter – 120 Mesh, 440 GPM, Flanged

BS4100H-120 – BALDR 4" H-Style Screen Filter, 120 Mesh

The BS4100H-120 is a 4" h-style screen filter built for commercial and agricultural irrigation systems. It uses a cylindrical stainless steel mesh screen to intercept particles before they reach sensitive downstream components such as drip emitters, micro-sprinklers, and solenoid valves. Rated to 145 PSI and 140°F, this filter suits open-field drip systems, greenhouse blocks, and pressurized sub-mains demanding reliable sediment control.

Key Features and Benefits

• 120 Mesh Stainless Steel Screen – Suited for drip and micro-irrigation protection (125 micron openings), protecting downstream components without excessive pressure drop.
• 337 in² Filtration Area – Large screen surface reduces flush frequency and maintains consistent flow even when partial fouling occurs.
• 440 GPM Maximum Flow – Sized for 4" pipelines operating at commercial irrigation volumes.
• 145 PSI Pressure Rating – Handles high-pressure mainline supply without risk of housing failure.
• 140°F Temperature Rating – Safe for systems using warm or solar-heated water supplies.
• Polypropylene Body – Corrosion-resistant and lightweight, reducing load on fittings and supports.
• Replaceable Cartridge – The stainless steel screen cartridge lifts out for cleaning or mesh-size change without replacing the body.
• 4-inch ANSI flange connections integrate directly into flanged mainline assemblies without adapters.

Construction

Body: UV-stabilized polypropylene. Screen: 304 stainless steel mesh. Seals: EPDM O-rings. The cartridge is a drop-in fit — unscrew the cap, lift out the screen, rinse or replace, and reassemble.
