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.
