eXtreme nanofibre filter offers higher filtration efficiencies

Nanofibres act as a pre-filter and capture most of the dust at the surface

The HemiPleat eXtreme nanofibre filter

A new HemiPleat eXtreme nanofibre filter from Camfil Farr Air Pollution Control (APC) offers higher filtration efficiencies, greater durability, and better resistance to pulse-cleaning than competitive products, the company says. These advantages can extend filter life and reduce operating and energy costs associated with industrial cartridge dust and fume collectors.

The standard eXtreme media delivers MERV 15 efficiency – higher than the base media rating of MERV 10 and the MERV 13 rating of competitive nanofibre products. Also available is a high efficiency (HE) MERV 16 eXtreme media that delivers tested efficiency of 99.999% on 0.5 micron and larger particles by weight.

A proprietary tri-layered technology is used to apply two layers of fine-pored nanofibres that act as a pre-filter to the base media, capturing most of the dust at the surface before it imbeds in the filter. This technology increases the filter’s cleaning ability and allows the base material to have larger pore sizes than standard cellulose media – reducing pressure drop while allowing the eXtreme fibres to provide a superior efficiency layer.

The HemiPleat eXtreme coating is so thick and durable that, unlike most nanofibre coatings, it is visible to the naked eye. It delivers long-term low pressure drop on dust produced by laser and plasma cutting, welding and thermal spray. The company says it can also bring longer service life and lower operational costs to many dry dust applications.

The eXtreme filters are available in a choice of media to meet special performance needs, with models available for new and retrofit applications.

Like all HemiPleat products, the eXtreme filter has a patented open-pleat design that allows better utilisation of the media pack, resulting in better airflow through the cartridge for enhanced performance. A new patent-pending double gasket around the perimeter of the filter prevents any dust from accumulating on top of the pan.
