Abstract
A stacking modular filter arrangement may be employed as a final filter for the dust collector for woodshop or other environment in which dust in an air stream is separated out and the exhausted air is filtered in the final filter to return to the ambient. The filter arrangement employs at least first and second filter modules of similar section, and a number of clamp members to hold facing end plates of the filter modules and pull the end plates against one another with one or more gasket members compressed between them. This arrangement permits the available filter area of the final filter to be customized to the customer's needs.
