The CFC 328 Series is a range of non-self-cleaning in-line protection filters designed to provide ‘secondary’ protection to process air systems. The rugged carbon steel painted construction is typically fitted downstream of a primary venting filter.

The CFC can provide protection to exhauster units on vacuum conveying systems, or prevent emissions to atmosphere in the event of a primary filter fault.
