FAQs
The L74M-6GP-QAN Excelon micro fog lubricator is designed to deliver precise oil mist lubrication for general pneumatic systems, reducing wear and extending component life. It supports inline or modular installation, making it suitable for both new builds and retrofits. With a 1 L aluminium bowl and micro fog technology, it maintains efficient lubrication across varied pipework and flow conditions, helping to minimize oil consumption and maintenance downtime in industrial environments.
The L74M-6GP-QAN utilizes a G3/4 port size. This standard size ensures compatibility with a wide range of Norgren Excelon components and common pneumatic accessories. When planning installation, verify matching threads and sealing interfaces with the chosen manifold or block to ensure a leak-free connection and straightforward maintenance access.
Yes. The Excelon L74M-6GP-QAN is designed for both inline and modular installation, offering installation flexibility to fit compact spaces or evolving process layouts. Inline installation simplifies direct piping, while modular mounting supports easier reconfiguration in response to changing production needs. This adaptability reduces downtime during changes and helps maintain consistent lubrication across varied system architectures.
Maintenance involves periodic checking of the manual drain and bowl level, with the option to service via the L74M service kit. The 1 litre aluminium bowl provides clear liquid level indication, aiding proactive maintenance to prevent lubrication gaps. Regular inspection of elastomer seals (chloroprene and nitrile) and compatibility with connected piping helps maintain performance and prevents unexpected downtime.
Key figures include the lubrication flow of 73 dm3/sec (155 scfm) and a start point of 0.94 dm3/sec, which inform how the device schedules lubrication at varying demand levels. Maximum inlet pressure is 17 bar, and the micro fog mode ensures a nearly constant oil/air ratio across flows. These metrics support reliable lubrication in long piping runs and help with process tuning and energy efficiency.
