Coarse Pocket Filters

Coarse Pocket Filters

The ISO Coarse Pocket Filters are multi-pocket bag filters which are made with Irema Ireland’s Ultraseal Plus welded cut pockets with air filter media that meet the latest ISO 16890 standard for coarse filtration efficiency.

The filter media construction consists of pockets which are ultrasonically welded, cut to size and supported by a corrosion resistant metal or plastic frame.

Each pocket is ultrasonically welded with 6 rows of internal spacers to allow the pocket inflate and provide an even airflow distribution, resulting in full utilisation of the air filter as well as much reduced initial resistance. Each separator is welded to the top and bottom layers of the media; the result is a strong seal, capable of withstanding high pressures of over 1000Pa.
