BD4100H – 4" H Disc Filter, 120 Mesh

The BD4100H is BALDR's largest disc filter, designed for 4" flanged pump station headers and high-volume agricultural mainlines handling up to 440 GPM. Its 527 in² polypropylene disc stack — the highest filtration area in the BALDR range — supports long service intervals even on turbid canal or surface water sources. Rated to 145 PSI for compatibility with booster pump systems.

Key Features

440 GPM capacity: Handles pump station output and high-volume distribution headers feeding large irrigation blocks.
527 in² filtration area: Maximizes disc surface area to extend cleaning cycles on high-sediment source water.
4" flanged connections: H-body flanged design integrates with pump station piping and heavy-duty mainline assemblies.
145 PSI rated: Handles booster pump discharge pressures without pressure reducers upstream.
Four mesh options: BD4100H-CART40 (coarse pre-filtration), BD4100H-CART80 (medium), BD4100H-CART120 (drip standard), BD4100H-CART150 (micro-irrigation fine).
In-depth disc filtration: Diagonal cross-groove polypropylene discs trap particles throughout the full stack depth for consistent downstream protection.
