Netafim™ Manual Disc Filter — 1in / 120 Mesh / 140 psi

Netafim™ Manual Disc Filter — 1in / 120 Mesh

The Netafim™ Manual Disc Filter delivers advanced inline filtration through a stacked grooved disc architecture that creates a three-dimensional debris capture network — far more effective at trapping fine particulates, algae, and organic matter than simple screen filters of equivalent mesh rating. Sized at 1 inch with 120 mesh filtration and a 140 psi pressure rating, it provides the particle removal needed to protect drip emitters, micro-irrigation heads, and precision irrigation hardware from clogging in greenhouse and hydroponic water supply systems.

The disc filtration principle works by compressing a stack of grooved plastic discs to create a labyrinthine flow path — incoming water is forced to change direction multiple times as it passes through the disc stack, depositing suspended particles in the grooves rather than passing them downstream. This deep-bed filtration captures particles that flat mesh filters would allow through, providing superior protection for sensitive emitter hardware and extending maintenance intervals between filter cleanings.

Key Features & Benefits

• Stacked Grooved Disc Filtration — Three-dimensional filtration matrix captures suspended particles, organic matter, and algae more effectively than flat mesh screens of equivalent mesh rating.
• 120 Mesh Filtration — Fine particle retention protects drip emitters, misters, and micro-sprinklers from clogging caused by suspended solids in irrigation water.
• 140 psi Pressure Rating — Handles the full pressure range of typical pressurized irrigation systems without housing distortion or seal failure.
• 1-Inch Port Sizing — Standard 1-inch connection fits directly into common irrigation manifold and mainline configurations.
• Manual Cleaning — Disassembles for manual disc stack cleaning when pressure differential across the filter indicates clogging — no disposable cartridges required.

Who Should Use This

Greenhouse drip irrigation operators, hydroponic system builders, and indoor growing facilities using micro-drip or low-flow emitters install Netafim disc filters upstream of emitter zones to prevent premature clogging from particulates, mineral scale, and biological matter in recirculated or surface-water supply systems. The 120 mesh rating is appropriate for protecting most commercial drip emitters and micro-jet sprinklers from particle damage.

Compatibility

1-inch port connections. 120 mesh / 125 micron filtration. Operating pressure: up to 140 psi. Flow rate: 5-26 GPH. Compatible with standard 1-inch NPT threaded irrigation fittings. Install with flow direction as indicated on the filter housing. Clean disc stack when pressure differential increases above normal operating differential.

Frequently Asked Questions

How do I clean the disc filter?

Close the upstream isolation valve, depressurize the line, disassemble the filter housing, remove and separate the disc stack, rinse discs under clean water to flush captured debris, reassemble, and return to service. For mineral scale buildup, soak discs in dilute acid solution per Netafim's maintenance guidelines.

What mesh rating do I need to protect my drip emitters?

A 120 mesh filter captures particles down to approximately 125 microns. Most commercial drip emitters require 120-200 mesh upstream filtration — consult your emitter manufacturer's specifications for the recommended minimum filtration level.

Can I use this filter with nutrient solution recirculation systems?

Yes — disc filters are compatible with nutrient solution systems. Organic components in nutrient solutions (amino acids, humic acids) may accelerate disc fouling, increasing the frequency of manual cleaning required.

How often should the disc filter be cleaned?

Cleaning frequency depends on water quality and particle load. Monitor pressure differential across the filter — when pressure drop increases noticeably above baseline, it is time to clean the disc stack.
