OA Series Filter Bags
The OA Series filter bags have a high oil and hydrocarbon absorption capacity, and are available rated at 1-25 micron with particle removal efficiencies >90%.
The filter bag has 3 or 4 layers depending on micron rating, and includes a central polypropylene microfibre layer with enhanced oil and hydrocarbon absorption properties, and an outer cover to eliminate fibre migration and give added support to the filter media. It is constructed with sewn seams, with a choice of any ring type, including our Welseal polypropylene collars.
Originally designed to remove silicones, fluorocarbons and hydrocarbons from electrocoat paints in the automotive industry, like all our filter bags, the OA Series is manufactured under silicone free conditions.
OA Series Filter Bag Brochure
The OA Series filter bags have excellent particle removal efficiencies, and therefore are not only used in applications requiring the oil absorbent properties of the filter media. For example, the OA Series is well suited to applications requiring an increase in filtration efficiency compared to using standard nominal rated felt bags or where industrial filter cartridges are used.
To give longer service lifetimes, the OA filter media can also be combined with a pre-filter layer of standard needlefelt or extended life filter media.
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.
