Mega Depth Series
The Mega Depth multi-layered filter bag range has been developed to optimise filtration efficiency, lifetime and dirt holding capacity in either a continuous or batch process. The constituent filter bag layers are customised and selected to meet the needs of the specific application, giving a filter bag which optimises the filtration process.
By combining a high number of layers of filter media in a way which progressively captures particles of differing sizes, the bag has the ability to hold a very high level of dirt without resulting in any significant pressure drop, leading to a long lifetime.
The overall micron rating of the finished ‘MD’ filter bag can range from 200 micron nominal to 1 micron at high efficiency.
The ‘MD’ filter bag can be constructed to fit any standard size filter bag housing or any bespoke or non-standard vessel.
Significant overall cost reductions and improvements are achieved in the filtration process by :
- Significantly increasing filter lifetime
- Reduction of filter change-out time and downtime
- Reduction of disposal costs / more environmentally friendly
- Minimises engineer exposure to process liquids
- Low void volume reducing the amount of unfiltered liquid in the filter vessel after use.
Typical applications include amine filtration, paints and coatings, inks, chemical and fine chemical, water treatment and parts cleaning.
Chemical Compatability Guide
|Media / Collar Type||Acids||Alkali||Solvents||Oxidants||Recommend Maximum Operating Temperature (*C)|
|Bag Size||Diameter (inches/mm)||Length (inches/mm)||Surface Area (m2)||Volume (l)||Maximum Flow Rate (m3/hr)*|
*Flow rate depends on factors such as filter media type, micron rating, and fluid being filtered. All dimensions are nominal.
Standard Filter Bags
Allied Filter Systems Ltd manufactures high quality liquid filter bags to fit standard size filter vessels, as well as custom designed products where requested. The constituent materials have been chosen for their purity, consistent high quality and repeatable performance. Filter bags are available in traditional stitched form or with a fully welded construction, and are fitted with a comprehensive choice of rings.
Sewn Needlefelt Filter Bags
Needlefelts are a versatile and cost effective media providing a high solid holding capacity for both non-deformable and deformable, gelatinous particles. By means of a depth filtration mechanism, particles penetrate and are captured throughout the depth of the filter media.
Fully Welded Filter Bags
All seams are welded rather than sewn, and combined with our positive sealing moulded Welseal (polypropylene or polyester) welded ring, no process liquid can bypass through needleholes caused by the sewing process or around a traditional metal ring. The Welseal ring forms a 360o hermetic seal between the filter bag and housing, ensuring that fully welded filter bags perform to a higher efficiency than a sewn equivalent.
