Gardner Denver ZS1060578 Air Filter Element

Gardner Denver ZS1060578 Air Filter Element is an OEM replacement part for Gardner Denver rotary screw compressors, designed to install in L7-11B units and the ESM 7-11 family. As the intake filter element, it traps dust and contaminants before they reach the compression chamber, protecting downstream components and helping maintain air quality. The part carries OEM number ZS1060578 (ZS1060578-IAC is the variant listed for L7-11B) and is sold under the Gardner Denver brand. This is an air-filter element—the component type is “element” and the filter type is “air”—with an approximate weight of 5.5 pounds. A cross-reference exists to Mann Filter C 1131/1 for ZS1060578. Replacement guidance commonly cited by suppliers recommends changing the air filter every 8,000 hours of operation or annually, whichever comes first, to preserve filtration performance and compressor efficiency.
