PROTECTS FILTERS FROM LARGER DUST AND PARTICULATE
The main job of a pre-filter is to protect the other more expensive filters in the extraction system. It is designed as a barrier layer, to capture the larger dust and particulate, protecting the HEPA filter and carbon filters from premature blocking and ensuring they achieve their maximum filtration potential. Different applications require different filter setups, but a pre-filter is almost always a necessity.
Most pre-filters have an efficiency grading of F5 – F7 and are directly related to the life of the HEPA in that the more particulates captured in it, the less can pass through and prematurely block the other filters in the unit, extending the filter life and minimising downtime for filter changes. 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.

Key benefits of a pre-filter:
- Protects the other filters
- Filters the larger dust and particulates
- Extends filter life
- Minimises system downtime
