Bag filter housings & filter bags · Australia

Bag filter housings and the bags that fit them.

Single, multi-bag, quick-open and duplex housings from 2 to 12 bags, ten filter bag media from 1 to 2000 micron, complete skids built around your duty — and hydraulic flushing units that clean whole systems to a verified cleanliness code. Supplied, certified and supported in Australia.

How to navigate this

Four things, and they work together

A housing without the right bag is a pressure vessel. A bag without the right housing is a consumable you cannot fit. We sell them as a pair, build them into a skid where the duty needs one — and when the system is hydraulic pipework rather than a tank, the same discipline scales into a flushing plant.

Trial Evidence

Hydraulic flushing units

Flushing a hydraulic system is a filtration job. This is the machine for it.

A new or rebuilt hydraulic system usually fails on what was left inside it — weld spatter, mill scale, sealant and assembly grit. The fix is not a pump on a trolley. It is flushing the whole system at high velocity, through serious filtration, until the fluid itself proves clean.

The HFU 600 is a self-contained flushing plant: two pumps covering 10 to 600 litres a minute, three heated 1,300-litre tanks carrying solvent, degreaser and flush water, and up to seven filtration stages down to 5 micron on the return line.

The proof is on board. An in-line particle counter reads the fluid as it circulates — the flush is finished when the count reaches your target cleanliness class, not when the clock runs out.

Why bag filtration

The cheapest way to take solids out of a liquid

Bag filtration is not glamorous. It is simply the lowest cost per kilogram of solid removed, across the widest range of fluids, with the shortest change-out time — which is why it is still the default first stage in most industrial liquid circuits.

Cost

A bag costs a few dollars and holds kilograms of solid. Cartridges cost more per unit of dirt held; centrifuges and separators cost more to buy and far more to maintain.

Change-out time

Twenty seconds to open the cover, lift the bag, drop a new one in. On a quick-open housing there are no bolts to walk around and no lifting gear.

Range

1 to 200 micron in felt, up to 2000 in mesh, in media that handle acids, alkalis, solvents, oils and food-grade duty.

Where it runs

The duties we are asked for

Ultrasonic and wash-bath circulation

Taking the soil you removed out of the bath instead of putting it back on the next part. See filtration in ultrasonic systems.

Coolant and cutting fluid

Swarf and fines out, fluid life extended, disposal volume cut.

Paint, ink and coatings

Gel, skin and agglomerate removed before the spray head sees it.

Water treatment and process water

Pre-filtration ahead of RO, cooling circuits, and wash-down recovery.

Oils, fuels and lubricants

Particulate out of hydraulic, transformer and lube oil. See the oil systems group.

Food, beverage and pharmaceutical

316L with food-grade internal polish and FDA-compliant media where the process requires it.

Tell us the duty, not the part number

Flow rate, fluid, temperature, particle size and how often you want to change bags. We size the housing and the bag around that and quote the pair, delivered and commissioned.
