Modular stacking filter system

摘要

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.

主权项

1. In a dust collection system in which dust in an air stream is passed through a final filter back into the ambient air, the improvement in which the final filter is formed of a stack of filter components of similar cross section, said stack including first and second cylindrical filter modules, each of the same diameter and each with an end cap at each end thereof defining an opening into a core of the filter and an outer rim, and with at least one gasket supported on at least one such end cap, such that the first and second filter modules have one of the end caps of one filter facing one of the end caps of the other filter, with said at least one gasket compressed therebetween; and further including a plurality of clamp assemblies each being removably fitted onto the facing end caps of the first and second filter modules, and each of said clamp assemblies including a hook member at each end thereof to fit onto an associated rim of one of said facing end caps, and hardware connecting the two hook members adapted to draw the facing end caps towards one another with said gasket compressed therebetween.
