BOFA DeepPleat Duo Pre Filter - Fume Extraction System

BOFA DeepPleat Duo Pre Filter Technology

Save filter life and money with our unique Pre-Filter for your BOFA fume extraction system.

Take a look at our dynamic animation which explains exactly why the BOFA DeepPleat DUO is the longest lasting pre filter available on the market as well as extending the life of your main filter reducing overall cost of ownership.

The unique product features of the DeepPleat and DeepPleat DUO ensure that particulate capture is optimised and that the life of the main filter is extended and the overall cost of ownership reduced.

The DeepPleat concept is designed around reverse flow operation. As the contaminated air enters the filter chamber the velocity is dramatically reduced, allowing the larger particulates to fall to the bottom and therefore clear of the filter media. The smaller, lighter particulate are then retained within the filter pleats. This allows a greater majority of the larger particulate to fall away from the filter surface and into the drop-out chamber within the filter enclosure giving a far greater efficiency and much longer life for the full filter area.

The BOFA DeepPleat DUO pre-filter incorporates a massive drop-out chamber within the filter, having a volume area of 15ltrs. Above the drop-out chamber but still within the housing there is a sealed 200mm deep pleat layer of F8 media giving a surface area in excess of 12 sq metres.

A specially moulded grommet style gasket situated within the drop-out chamber makes it easy and safe for operators to undertake the initial installation and replacement of used filters. This safety aspect of the design is an important feature bearing in mind the different and in many cases, harmful contaminants found within a used filter.
