Cartridge FilterImperial Systems Inc. says its new DeltaMaxx cartridge filter delivers twice the service life, clean air and cost savings as competitors’ products. The DeltaMaxx’s nano-fiber filtration technology provides the industry’s highest efficiency compared with others in its class, officials say. The filter was developed primarily for use within Imperial’s CMaxx compact dust collector, and is offered in a variety of sizes. The filters can easily fit other well-known units.
