Product Features

Key Features of Hand-Operated Semi-Automatic Screen Filters

Cleaning Without System Disassembly

Unlike standard Y-filters or T-filters that require removal for cleaning, this filter operates with an external shaking handle. The internal mechanism scrubs the screen surface while the filter remains in line, eliminating the need for system shutdown during routine maintenance.

Large Filtration Area Design

The filter incorporates an oversized screen element that provides increased dirt-holding capacity. This design maintains lower pressure drop under moderate sediment loads, extending intervals between cleaning operations.

Stainless Steel Mesh Filtration

The filter uses precision-woven stainless steel mesh to capture suspended particles, protecting downstream drip emitters, sprinklers, and valves from clogging. Multiple mesh sizes are available to match different water quality conditions.

Simple Hand-Operated Mechanism

The cleaning system requires no tools or specialized training. Farm workers can restore filter function by turning the handle when pressure differential increases.

Engineering Plastic Construction

The filter body is manufactured from engineering plastics with UV stabilizers, providing resistance to agricultural chemicals, sunlight exposure, and mechanical stress encountered in field conditions.

Multiple Connection Options

The filter supports bayonet or threaded connections to accommodate different installation requirements. The modular design facilitates integration into new or existing irrigation systems.

Product Uses

Industrial Applications of Mesh Irrigation Filters

These filters function across multiple agricultural and landscape settings:

  • Greenhouse irrigation systems requiring regular maintenance

  • Small to medium farm operations with drip or sprinkler systems

  • Nursery operations using micro-irrigation for container plants

  • Field crop irrigation with drip tape or sprinklers

  • Landscape irrigation for parks, gardens, and commercial properties

  • Backup filtration for systems with primary automatic filters

Installation and Operation Guidelines

Install the filter after the pump and before downstream irrigation equipment, ensuring adequate space for handle operation. Connect inlet and outlet according to flow direction arrows on the filter body, and seal threaded connections with PTFE tape. Install pressure gauges before and after the filter to monitor pressure differential.

Clean the filter when pressure differential increases by 0.5-1.0 bar from the clean condition. Turn the shaking handle several rotations to scrub the screen surface. Particles exit through the bottom drain or settle in the sump. Continue turning until resistance decreases, indicating a clean screen.

Perform weekly inspections of pressure differential readings and connection seals. For heavy sediment loads, occasional disassembly may be required for thorough cleaning. Before winter, drain the filter completely to prevent freezing damage.

Troubleshooting for Screen Filter Systems

Problem

Possible Cause

Solution

Verify flow within design range

Water quality worse than design

Clean more frequently

FAQ

FAQ About Semi-Automatic Filters

How does the hand-operated cleaning mechanism work?

The filter contains an internal cleaning mechanism connected to the external handle. Turning the handle activates the mechanism, which scrubs the screen surface and releases trapped particles without removing the filter from the system.

Do I need to shut down the irrigation system to clean the filter?

No, the filter can be cleaned while water continues to flow through the system. Simply turn the handle several times without shutdown or disassembly.

How often should I clean the filter?

Cleaning frequency depends on water quality. Monitor pressure differential and clean when it increases by 0.5-1.0 bar from the clean condition. This interval may range from daily to monthly depending on sediment levels.

What is the difference between S and L models?

S and L indicate different dimensional configurations. Both models offer the same flow capacity but have different body lengths to accommodate varying installation space requirements.

Can this filter be used with well water containing sand?

Yes, these filters work with well water containing sand. The large filtration area handles sediment loads, and the hand-operated cleaning system simplifies maintenance.
