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 BOFA DeepPleat DUO pre-filter incorporates a massive drop-out chamber within the filter. Above this chamber but still within the housing there is a sealed deep pleat layer of F8 media giving a surface area in excess of 6/12/30 sq metres.

The DeepPleat DUO is available in three different sizes, offering different chamber sizes and surface media areas:

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.

As the contaminated air enters the inside of the cartridge chamber, the velocity drops slowing down the airflow causing in the larger and heavier particulates to fall within the cartridge sump. The sump also allows larger particulates that build up during operation to drop away from the filter through the true nature of reverse airflow design.
