Filtaworx Automatic Screen Filters

Filtaworx Automatic Screen Filters Built for Dirty Australian Water

Filtaworx Automatic Screen Filters are self-cleaning water filters that flush themselves without anyone opening a lid. Every unit on this page is stocked and priced by Pumptastic, an Australian pump specialist based in Perth. We list real prices on all 88 models because we got sick of watching growers and site managers chase three suppliers for a number. Sizes run from DN50 through to DN450, screens from 50 to 800 micron, all rated to 10 bar with 316 stainless steel elements.

Here is why they matter. Bore water in Western Australia is rarely clean. Pull from the Gnangara Mound or the Yarragadee and you get iron, silica sand, and calcium carbonate. Run that through drip tape or a centre pivot and emitters block within a season. A manual screen filter means somebody drives out, shuts the line down, and scrubs a basket. Filtaworx Automatic Screen Filters remove that job entirely by backflushing on a pressure signal.

The mechanism is the clever part. When solids build on the screen, pressure across the filter drops by about 40 to 50 kPa. That triggers a rinse. Escaping backflush water spins the internal cleaning mechanism, so on hydraulic models there is no motor and no power supply at all. Line pressure does the work. Flow keeps moving downstream during the flush, which usually takes five to seven seconds. Fewer moving parts means fewer things to fail in a paddock 400 km from a spare.

FILTAWORX is designed, built, and tested in Australia, in Melbourne. That is not marketing trim. It means brochures use metric units, flanges match local pipework, and screens are on a shelf in this country when you need one. We have watched imported filters sit dead for eleven weeks waiting on a European element. That does not happen here.

How to Choose the Right Filtaworx Automatic Screen Filter

Six numbers decide the model. Get these right and selection takes ten minutes.

• Peak flow rate, not average. Size on the highest flow the line will ever see, in m³/hr or L/sec.
• Micron rating. Drip and micro-sprinkler usually want 120 micron. Dust suppression and stock water tolerate 200 to 400 micron. Cooling circuits and misting often need 50 to 80 micron.
• Line pressure. Hydraulic Filtaworx Automatic Screen Filters need at least 200 kPa to drive the flush cycle. Below that, choose an electric controller.
• Dirt load. Total Suspended Solids drives flush frequency and whether you need an extended-area body.
• Solid type. Sharp sand behaves nothing like algae or paper fibre.
• Power available. No power on site means hydraulic control. Grid or solar means the 240V AC electric option.

If those numbers are not to hand, send us a pump curve and a water test. Our team sizes filters daily and we would rather talk you into a smaller unit than sell you a DN300 you do not need.

Hydraulic or Electric Control

Hydraulic models run on line pressure alone. They suit remote bores, travelling irrigators, and any site where running a cable is more expensive than the filter. Electric models with a 240V AC controller give you timed flushing, a differential pressure switch input, and a dry contact you can wire back to a PLC or SCADA head. Mine sites and municipal plants usually want the electric version for that reason.

We also stock a pressure sustaining valve variant, marked HV. That option holds flush pressure steady when your supply is marginal, which is common on shared irrigation mains in the Wheatbelt during peak draw.

Filtaworx Automatic Screen Filters for WA and Regional Sites

Most of our Filtaworx Automatic Screen Filters go to jobs outside the metro area. Vegetable growers in Carnarvon and Gingin. Vineyards through Margaret River and the Great Southern. Dust suppression and process water on Pilbara and Goldfields operations near Port Hedland, Karratha, and Kalgoorlie. Horticulture around Manjimup and Harvey. Ord River irrigation up near Kununurra.

Regional freight is the part suppliers gloss over. We dispatch fast, ship Australia wide, and freight is free on orders over $100. Larger filters travel as bulky freight, so ring us and we will price the run before you commit. Full detail sits on our delivery and shipping page.

One practical note from experience. On iron-heavy bore water, install the filter after any aeration or oxidation stage, never before. Ferrous iron passes straight through a screen while it is still dissolved, then oxidises downstream and blocks your emitters anyway. We have seen good filters blamed for that three times this year.

The Rest of the Filtaworx and Helix Hydro Range

Screen filters are one option among several. If your water carries algae or organic matter rather than sand, brush filters usually outperform screens. Browse the Filtaworx automatic brush filters or the lower cost Filtaworx semi-automatic brush filters for those jobs. For a closer look at the self-cleaning range specifically, see Filtaworx automatic self-cleaning screen filters.

On tighter budgets, Helix Hydro semi-automatic screen filters and Helix Hydro manual filters cover lighter duty. Everything sits under our full water filtration range.

A filter is only as good as the pump feeding it. Undersized pumps cannot generate the pressure a backflush needs. Pair your Filtaworx Automatic Screen Filters with the right submersible bore pump, a pump controller, a pressure tank, and stainless steel BSP fittings so the whole system holds together.

Why Buy Filtaworx Automatic Screen Filters From Pumptastic

We publish prices. Most competitors hide theirs behind a quote form, which costs you two days per comparison. We show 88 models with figures on screen so you can budget the job today.

We answer the phone with people who size pumps for a living, not a call centre. Ring (08) 6384 5884 between 9am and 5pm weekdays, or email hello@pumptastic.com.au. Tell us the flow, the pressure, and what you are protecting, and we will name a model in that call. If a Filtaworx unit is the wrong tool for your water, we will say so.

Frequently Asked Questions

How do Filtaworx Automatic Screen Filters clean themselves?

A pressure drop of roughly 40 to 50 kPa across the screen triggers a backflush. Escaping water spins the internal cleaning mechanism and scours the whole screen surface at high velocity. The cycle takes about five to seven seconds and flow continues downstream throughout.

What micron rating do I need?

Match it to the smallest opening you are protecting. Drip emitters typically want 120 micron. Sprinklers and stock water usually run 200 to 400 micron. Misting and heat exchangers often need 50 to 80 micron. Screens swap out on site if you change crops or systems later.

Do Filtaworx Automatic Screen Filters need electricity?

Hydraulic models do not. They run entirely on line pressure, which is why they suit remote bores. Electric models use a 240V AC controller when you want timed flushing or a signal back to a control system.

What is the minimum pressure required?

Around 200 kPa, or 30 psi, for hydraulic control. If your line sits below that during peak draw, choose an electric controller or add a booster ahead of the filter.

What sizes are available?

Pumptastic stocks DN50 through DN450 in this collection, covering roughly 40 to 1400 m³/hr depending on model and screen area. Extended area versions marked EX give more screen surface in the same body size for heavier dirt loads.

How much water does each flush use?

Usually 20 to 30 litres per cycle on smaller units, more on larger bodies. Flush frequency depends on how dirty your source water is. On clean bore water you may see a handful of flushes a day. On dam or river water it can be far more.

Are these suitable for mining and municipal use?

Yes. The range covers industrial, municipal, mining, and agricultural duty. Sites usually specify the electric controller so flush events log back to SCADA.

What does the filter body use for corrosion resistance?

Stainless steel bodies as standard with 316 stainless mesh screens, and corrosion resistant materials throughout. That matters on bore water carrying chloride, which is common across much of inland Western Australia.

Can I install one horizontally?

Most units mount in any orientation with minimal clearance, and larger models in this collection use a parallel inlet and outlet arrangement. Confirm the specific model before you pour a slab, and we can check the drawing with you.

Do you ship to regional Western Australia?

Yes, and Australia wide. Free freight applies to orders over $100. Larger Filtaworx Automatic Screen Filters ship as bulky freight, so call us for a quote on that leg before ordering.
