Filtaworx FWSA2 Series Inline Semi-Automatic Brush Filters for Irrigation Water Systems

The Filtaworx FWSA2 Series provides screen filtration in an inline arrangement, with flanged models from 100mm to 300mm. Its inlet and outlet configuration suits straight-through pipework, offering an option for irrigation installations where filter cleaning needs to fit around regular watering schedules. Select the model according to operating flow and downstream filtration requirements.

The range combines a 304 stainless steel housing with a 316 stainless steel screen and brush. During filtration, suspended particles collect inside the screen. Screen selection should reflect the water source and equipment being protected; the base FWSA2 part number identifies connection size rather than the fitted aperture. helixhydro.com.au

Cleaning involves opening the flush valve and rotating the external handle, which moves the brush across the screen and discharges loosened material through the drain. This can be completed without dismantling the housing or interrupting downstream flow. Cleaning frequency depends on the screen aperture, operating flow and sediment loading, making routine inspection important when establishing a maintenance schedule.
