Meltblown Non-Wovens

Irema manufactures its own meltblown non-woven material for use in filter media applications and facemasks.

Manufacturing our own melt-blown filter media gives us control over the quality of our products and allows us to constantly innovate in filter media materials. Our melt-blown technology has led the way in the protection of users against harmful airborne contaminants and, in more recent years, against new threats posed by flu viruses and hospital acquired infections such as MRSA. Irema’s research and development programmes continue to focus on maximising the protection offered by its masks.

Irema’s unique melt-blown technology produces fine microfibers ideally suited for a range of filtration applications. The flexibility of this technology allows us provide continual improvements in the performance of our filter media in removing airborne contaminants. In addition to our range of filter media for face masks, Irema has also developed Micro 2000 plus for use in Heating, Ventilating and Air conditioning (HVAC) applications.

HVAC Filter Media

With a variety of filtration technologies and styles to choose from, as well as industry standards such as EN 779 and ASHRAE 52.2 for evaluating filtration performance, engineers are looking to select air filters that will improve Indoor-Air Quality (IAQ), maintain HVAC-system cleanliness, and reduce energy consumption simultaneously. IREMA’s Micro 2000 filter media offers such a solution.

Micro 2000 Plus

Irema’s unique Micro 2000 Plus has fine fibres with diameters as low as 0.3 micron. Regulations such as EN 779 and ASHRAE Standard 52.2 governing Indoor Quality Air Quality have become accepted as the norms in the Industry and as a result, more manufacturers of HVAC systems are looking for filter media that will maximise filtration efficiency at the lowest possible pressure drop. IREMA’s Micro 2000 is compliant with these criteria. It is a lofted three-dimensional filter media, with a mixture of coarse and fine fibres, meeting efficiency requirement’s while giving as low a pressure drop as possible. This provides the ideal synthetic fabric for manufacturing bag filters, giving maximum performance.

Pre-Welded Rolls

For customers who do not have the capability of making filter pockets themselves, Irema offers pre-Welded Rolls of Micro 2000 Plus media that are ultrasonically welded and ready for cutting into pockets. Each welded roll has 6 rows of internal spacers to allow the pocket filters to inflate and provide an even airflow distribution, resulting in full utilization of the air filter as well as much reduced initial resistance. Each separator is welded to the top and bottom layers of media; the result is a strong seal, capable of withstanding high pressures of over 1000 Pa.
