Sizing a 2 in Irrigation Filter Against Your Line
Start at the bottom of the range rather than the top. This body begins at 40 GPM, and running one below that starves the discs of the pressure they need to compress and seat. If your line sits under 40, a 1.5 in Super at 10 to 52 GPM is the correct part. Ports are 2 in MPT on a dual cartridge body, so there are two stacks doing the work rather than one.
What a High Flow Disc Filter Asks in Return
Two stacks filter more and they also take longer to service, which is the honest trade on any high flow disc filter. The black 140 mesh stack here screens to roughly 115 micron, the finest standard option below the 200 mesh reserved for HP bodies. Finer catches more, loads faster and costs more pressure as it fills. Match it to the smallest orifice downstream instead of reaching for the finest available. Confirm the body before ordering. Netafim supplies the 2 in as Lite and HP. The Lite runs 40 to 110 GPM at 115 psi. The HP runs 40 to 120 GPM at 174 psi. If your system runs anywhere near 115 psi that difference decides which one is safe. The filtration principle does not change with size. Grooved rings compress under working pressure and water crosses the channels between them. Debris is trapped through the depth of the column rather than on a single face.
Key Features
- Flow from 40 GPM: Below that a 1.5 in Super at 10 to 52 GPM is the correct part instead.
- Dual cartridge body: Two disc stacks share the work, which is how the 2 in reaches these flows.
- 140 mesh, roughly 115 micron: The black stack, and the finest option outside the 200 mesh HP body.
- 2 in MPT inlet and outlet: Male pipe thread both ends for standard irrigation fittings.
- Lite and HP bodies differ: 110 GPM at 115 psi against 120 GPM at 174 psi. Confirm which one ships.
- More area, longer service: Two stacks hold more debris and take proportionally longer to strip and rinse.
