Cartridge & Bag Filters

Ideal for removing large amounts of coarse contamination. We offer a variety of filter cartridges and bag filters to suit many applications.

Our meltblown cartridges are made up of numerous fibre zones, providing a graded structure throughout the filters depth. Having multiple zones means our filters can perform for longer through the use of depth filtration.

Supplied in either 10”, 20”, 30” or 40” lengths.
Gradients ranging from 1 – 100 microns.

Polypropylene material with an outside diameter of 63mm.
D.O.E as standard, – also available with thermally welded end caps such as ‘Amazon A’ style, and fin / flat closed ends.
10” and 20” lengths also available in large diameter with an o.d. of 114mm, and ranges of 1 – 50 microns.
Can be supplied as high efficiency, high collapse strength or absolute, as well as wound polypropylene cartridges with micron gradients of 1 – 200.

Pleated filters remove the suspended solids on the surface of the filters material.

They are designed to maximise dirt holding capacity and minimise pressure drop at high flow rates.

The filter media is both bacteria and chemical resistant and has a high wet strength.

The media is formed around a polypropylene core for added strength.

The standard filters offer 95% removal efficiency and the absolute range are 99%.

Cyclonic filters operate by pumping the liquid to be filtered tangentially into the filter body.

This results in a cyclonic action within the filters body whereby the dense suspended solids are thrown to the outside edge of the vessel under centrifugal force.

The filtered liquid then reverses direction travelling up through the filter body and out leaving the dense solids at the base of the vessel where it is removed through the ½” drain valve.

FilterBlue cartridges are specifically designed to suit the FilterBlue housings. Each 20” cartridge filter can operate at pressures up to 10bar, with a maximum flowrate of 12,000 – 18,000lph, depending upon micron rating. Higher flowrates can be achieved by using multiples of cartridges.

95% removal efficiency.
Available in dual gradient melt-blown (1-10, 5-20, 20-50 or 50-90micron).
Available in pleated polypropylene (1,5,10,20 or 50micron).
Available in washable pleated polyester (20 or 50micron).

The washable filter may be washed and re-used up to 400 times, thereby reducing operating costs in waters with high suspended solids.

FilterMax cartridges are specifically designed to suit the 13” or 20” FilterMax housing.

95% removal efficiency with a high flow rate across the range.
Available in dual gradient melt-blown (1-10, 5-20, 20-50 or 50-90micron).
Available in pleated polypropylene (1,5,10,20 or 50micron).
Available in washable pleated polyester (20 or 50micron).

Flowrates vary between 12,000 – 27,000lph depending on size and micron rating.

FilterOne cartridges are specifically designed to suit the 23” or 40” FilterOne housing.

95% removal efficiency and high flow rate across the range.
Available in dual gradient melt-blown (1-10, 5-20, 20-50 or 50-90micron).
Available in pleated polypropylene (1,5,10,20 or 50micron).
Available in washable pleated polyester (20 or 50micron).

The washable filter may be washed and re-used up to 400 times thereby reducing operating costs in waters with high suspended solids. Flowrates vary between 10,000 – 30,000lph depending on size and micron rating, and operate at pressures up to 6bar.

We supply filter bags to suit size 1, 2, 3 & 4 filter housings manufactured from polyester & polypropylene felt with either snap ring, “G” or “F” collar and in filter ranges 1-100 micron, at 75% efficiency.

Nominal Bag Dimensions (Dia x Lg)

Size 1: 7” x 16”
Size 2: 7” x 31”
Size 3: 4” x 9”
Sze 4: 4” x 15”

Special sizes can be accommodated on a made to order basis.

Bag & Filter Housings

Single and multi-cartridge housings are available in different materials such as stainless steel AISI 316, fiberglass and different plastic materials such as polypropylene, polyamide and PVC.

We supply a range of stainless-steel filter housings for cartridge and bag applications. Offering single cartridge to multi-round cartridge / bag housings there is a product for every application. Our multi-cartridge housings are supplied with a universal cup that allows either 222 (code 3 EG and code 8 EH) or DOE filters to be fitted to the same housing. VB series housings use a V-band clamp lid sealing mechanism and are suitable for price sensitive applications.

SB Series housings feature a cast lid with integral hinge mechanism, and swing bolt fixings to ensure a positive seal. Suitable for higher pressure applications SB housings are engineered to provide many years of reliable service.

DL series housings feature a davit lift lid raising mechanism making opening and closing the housing easy and safe. DL series housings are available in multi-bag and multi–cartridge configurations.

TL series housings feature a cast lid with swan neck inlet configuration, integral hinge assembly and swing bolt fixings for a positive seal. Because the lid sits directly on the sealing ring of the filter bag the chance of bypass is greatly reduced.

TL series housings are designed to give many years of reliable service.

TL Series are only available for size 1 and 2 filter bags.

The filter housings are a three-piece design to facilitate easy exchange of the cartridge filter element, with the filter head & retaining clamps being manufactured from polypropylene and the filter bowl from Styrene Acrylonitrile.

10” & 20” options, as well as large diameter 20″.
The filter bowl may be supplied as opaque or transparent.
Tested to operate for over 200,000 cycles from 0-10 bar.
Supplied with/without a wall bracket for 1 or 2 filters and a spanner.

The FilterBlue housing is manufactured from glass reinforced plastic and has been developed to contain ‘filstar’ filter cartridges.

The FilterBlue housings offer:

High flow rates
High pressure operations
Corrosion resistant materials
Easily replaceable cartridges.

The filter cartridge options for this housing include: Polypropylene Meltblown, Pleated Polypropylene and Pleated Polyester Net and come with a rating of 1 to 50 microns.

The FilterMax housing is made of reinforced Polyamide (PA) to ensure very high mechanical resistance, absolute corrosion resistance and very long life.

FilterMax is available in two different sizes 13"and 20". Each housing will fit a single high flow filter cartridge which guarantees 18 m3/h flow rate for the 13" and 27 m3/h flow rate for the 20".

The filter cartridge options for this housing include: Polypropylene Meltblown, Pleated Polypropylene and Pleated Polyester Net.

Ever thought about a self-cleaning filter?

The advantage of a self-cleaning filter is that as it becomes fouled it will clean itself discharging the suspended matter to drain. As such it can accommodate variation in the incoming waters suspended solids levels.

The self-cleaning filter is fitted with a range of filter elements from 50 to 500 micron and the initiation of the cleaning mode is via either a timer, a rate of flow meter, or a pressure differential switch.

Membranes & Membrane Housings

All the parts found on our filtration plants can be bought as spares.

Our range of membranes include those for Reverse Osmosis, Nano-Filtration and Ultra-Filtration suiting a wide variety of applications.

We can also supply membrane housings manufactured completely from glass reinforced epoxy resin. The membrane pressure vessels are suitable for multiples of either 4” or 8” membranes and pressure up to 1200psi.

MEDIA FILTRATION

Media filters are used to treat specific contaminants from water supplies. Different medias are available to suit different foulants. Medias are available to remove iron, manganese, ammonia, arsenic, turbidity, organics, chlorine, suspended particulates, nitrates, and acidity. As filtration proceeds, the filter bed gradually becomes fouled and requires backwashing and/or regeneration. Flow through the bed is reversed via an automatic multi-port valve, whereby the accumulated debris is discharged to drain and if required rinsing with a suitable regenerant is undertaken
