Interpocket Filters

Interpocket Filters

Designed to provide a cost effective and efficient means of handling large air volumes of constant air flow. These filter are suitable to be used in applications such as hospitals, office blocks, pharmaceutical plants. These are found in a range of sizes and media efficiencies


The Interpocket filters are extended surface, high capacity air filters. They are designed to provide a cost effective means of handling large air volumes of constant air flow, with high-particulate concentration of sub-micron particles. The media construction combines a compact design with excellent airflow characteristics, providing potential for significant energy savings.

In applications requiring a high degree of cleanliness, interpocket filter excel as final filters in air handling systems, or as a secondary filter in a three stage filter bank that uses HEPA or ULPA filters as the final filters Interpocket filters are suitable in applications such as:

  • Hospitals
  • Office buildings
  • Pharmaceutical
  • Universities


Each bag is manufactured from a multilayer medium comprising a unique blend of synthetic fibres. The medium has a graded density structure, with a prefilter layer, a fine filtration layer of the specified grade and a backing layer to provide strength. This give the inter pocket bag filter. A high dust holding capacity and a low pressure drop, while providing a compact long life filter with energy saving capabilities.

All pockets are assembled into a ‘U’ shape formed header frame, which provides a compact, ridged and robust filter structure. Inter pocket filters shut installation into existing front and side withdrawal frames or with optional mounting hardware can be installed into filter banks. Where the bank height exceeds 2 meters (ft),it’s recommended that continuous stiffening bars be installed between alternate tiers of frames.
