Gusmer Enterprises’ Select filter housings are designed as a cost-effective system for high capacity liquid filtration applications. The Select housing line accommodates 12” diameter Cellu-Stack ® filters. All housings are available in 1, 2, 3, or 4-stack high versions, which can be modified with the use of Cellu-Stack adapters to accept fewer Cellu-Stack filters for partial batch runs or other applications requiring fewer lenticular filters.

Cellu-Stack Application Notes

• Place a quick acting check valve at the housing outlet to avoid integrity breaches that can be caused by backpressure • Verify all cartridge gaskets are in place and in good condition to ensure optimal sealing • If filter life is not fully exhausted by a single filtration, DO NOT remove used filters from the housing for storage between uses. Instead, used filters can be stored IN the housing for short term periods by following these steps:

Shut Down: After completion of the filtration cycle, sanitize the filters with the same method used to prepare the filters (i.e. steam or hot water flush) Storage: Drain the housing, apply 2 psi gas pressure (i.e. CO 2 , nitrogen) while the housing is still warm (to avoid a vacuum upon cooling) and close all ports Restart: When restarting for another filtration cycle, repeat the sanitization procedure just as you would for normal filter preparation
