BOFA DeepPleat & DeepPleat DUO Filters

Many years of designing and manufacturing fume extraction and filtration systems for a variety of industries has given BOFA the experience and expertise to ensure that our product solutions are the best available on the market. Our understanding of industrial processes and applications are reflected in the design and manufacturing procedures applied to our range of patented filters.

Critical to filter performance and working life is the need to ensure that the contaminated air remains in contact with the carbon bed (specific carbon types are chosen for different applications) for a period of time sufficient to ensure that no contaminants or odours are emitted. This time period is typically referred to as the dwell time. Our product designs consider the balance between air flow rates and the type, depth and surface area of the carbon used to ensure suitability for the contaminants associated with the application and to ensure that appropriate dwell times are achieved.

There is also the risk that filter performance may be compromised due to conditions known as bypass and or tunnelling. End users will typically associate such problems with premature carbon saturation, where in fact both problems more typically relate to poor design or manufacturing techniques, resulting in insufficient capture of contaminants and the discharge of odours into the workplace. The manufacturing and test procedures developed by BOFA ensure that the risk of such problems have been eliminated giving end users the confidence that our filters will give trouble free operation throughout their lifetime.
