Use cases & applications
Oil Vapor Removal in Food Packaging
In food packaging facilities, compressed air must be free of oil vapors to prevent contamination. The activated carbon media in this filter effectively adsorbs oil aerosols, ensuring product safety and compliance with industry standards.
Odor Control in Pharmaceutical Production
Pharmaceutical manufacturing requires odor-free compressed air for sensitive processes. This filter removes unpleasant smells caused by oil degradation, maintaining a clean environment and protecting product integrity.
Continuous-Duty Industrial Applications
For operations running compressors around the clock, the low differential pressure of 60 mbar minimizes energy loss. This filter maintains consistent flow while reducing load on the system, supporting efficient continuous operation.
Inventory Consolidation for Multi-Brand Fleets
Facilities with compressors from Atlas Copco, Boge, Gardner Denver, and Kaeser can standardize on one filter. This simplifies stock management and reduces the risk of using the wrong filter across different equipment.
Frequently asked questions
How do I confirm this filter fits my compressor?
Check your current filter's outer diameter (86 mm) and body height (180 mm). If these match, this filter is a direct replacement. It also cross-references many brands including Atlas Copco, Boge, Gardner Denver, and Kaeser, but always verify dimensions.
What does the activated carbon media filter out?
Activated carbon is designed to remove oil vapors, hydrocarbons, and odors from compressed air. It is not for particulate removal; use a pre-filter for particles before this stage.
What are the thread or connection details?
The product specifications do not include thread size or connection type. Please measure your existing filter's connection or consult your equipment manual to ensure compatibility.
Is this filter genuine OEM or aftermarket?
This is an aftermarket replacement, not genuine OEM. It is built to the original dimensions and ratings and serves as a direct replacement for many branded filters.
How do I install and replace this filter?
Installation is straightforward: shut down the system, depressurize, unscrew the old filter, and screw in the new one. Ensure the O-ring seals properly and tighten to the manufacturer's torque specification.
