High Capacity Filter Bags
Newly installed filter bag housings or existing systems can utilise High Capacity filter bags, which increase the filtration surface area by 70% compared with a similar sized standard bag.
The High Capacity bag is situated within a stainless steel filter basket with inner support core. Baskets can be supplied to retrofit existing standard size filter bag housings.
Liquid enters the bag and flows through both the outer surface and the central core, enabling higher flow rates to be achieved compared to the equivalent sized standard filter bags. The increased filtration surface area results in a higher dirt holding capacity and therefore prolongs the service life of the filter bag.
High Capacity Filter Bag Brochure
By utilising a High Capacity filter bag in a new filter installation, a smaller, lower cost filter housing can achieve the desired flow rate and dirt holding capacity. When retrofitting an existing filter housing with a High Capacity basket, its performance capability can be increased at minimal cost.
A High Capacity bag also reduces the volume of retained liquid in the filter bag by 30% compared to a standard bag system, lowering the filter bag removal weight and decreasing product wastage.
As standard, construction is from our extended life filter media, although High Capacity bags can be manufactured from any of Allied’s filter media, including our range of high efficiency melt blown materials. The filter bag features our Welseal collar to provide an excellent seal with the filter housing, and a support ring in the base to assist installation.
High Capacity filter bags are available for size 1 and size 2 filter housings.
Allipure Series – High Efficiency Filter Bags
Allied Filter Systems Ltd has developed the Allipure series, a unique range of absolute rated filter bags rated from 5 to 0.6 micron, which perform to an efficiency of 99.98% (Beta 5000) at the stated micron rating. For processes requiring absolute and/or sub micron liquid process filtration, the use of filter cartridges has previously been the method of choice to achieve high performance in critical applications with consumable filter elements.
Extended Life Filter Bags
Increased thickness of the filter media compared to that of the equivalent standard felt filter bag enables an increased retention of particles. In addition, the extended life filter media has a graded density structure i.e. progressively smaller particles are captured as the fluid follows a tortuous path through the media, stopping the filter bag from blinding prematurely. The result is a filter media with a higher dirt holding capacity, leading to increased filter bag lifetime.
Filter Bag Accessories
Allied Filter Systems Ltd is able to supply a wide range of bag filter accessories to complement our range of filter housings and also those from other manufacturers. Restrainer baskets – Stainless steel 316L in all industry standard sizes and available in a variety of styles to fit all types of housings. Baskets can also be manufactured with a stainless steel mesh lining (37 to 840 micron) or produced from perforated sheet other than the standard 3mm, commonly 1mm to 10mm. Coated baskets (e.g. Halar) are also available.
