Abstract
A closed filter container containing at least one filter cartridge mounted on a plate, whose periphery is clamped between the lid and rim of said container electrically isolating said cartridge and plate from the walls including the lid of the container as disclosed in applicant Harms' prior U.S. Pat. No. 3,720,322. Mounted between the plate and a wall of the container is at least one electrically conducting resilient finger which maintains electrical contact across the gasket which isolates the plate and cartridges regardless of the flexing of the plate due to variations of pressure inside the container. The plate also is provided with three handle members to facilitate removal of the plate and cartridges from the container. The three handle members also act as legs to stably support the plate and cartridges during replacement of the cartridges. Furthermore, these handles have improved configurations for both ease in handling and strengthening.
