fact sheet Properly engineered cages help protect your filter investment. Omni Cage The Omni cage top was developed to facilitate snap- A well-built cage is critical to the overall performance and band bag removal. It has a detachable top which durability of your filter bag. GE Energy cages feature evenly allows removal of the cage top first. With the cage spaced rings and wires, with a rounded bottom pan (never top no longer blocking access to the snap-band, the band can be snapped loose from the tubesheet, and cringed) to help ensure proper filter fit.
