FAQs
What you need to know is that the L68C-6GP-EUN supports modular mounting using the wall bracket 18-001-979 and Yoke assemblies (Y68A-6GN-N1N/N2N). Align the G3/4 inlet to your compressed air line, ensure the bowl drain is closed when starting, and verify the plug-in system seats correctly. This keeps installation straightforward and minimizes retrofit risk in evolving lines.
The unit delivers a nominal flow of 175 dm3/sec with a defined start point at 6 dm3/sec, supporting a wide operating range. The integrated flow sensor maintains a nearly constant oil-to-air ratio across varying demand, improving lubrication stability, reducing oil waste, and ensuring predictable cylinder and tool performance in dynamic production environments.
Yes, it is designed for rugged industrial use, including large bore cylinders, air motors, and tooling stations. The aluminium body and closed-bowl design enhance durability and contamination control, while the Olympian Plus modular system supports scalable configurations with wall brackets and yoke fittings for fixed or semi-mobile installations.
Check for CE compliance and IP-rated variants where applicable, and confirm SIL compatibility with your control architecture if safety interlocks are involved. While the product family is built to meet typical industry expectations, verify the exact certification and rating on your specific order and datasheet to ensure regulatory alignment for your facility.
Routine maintenance is simplified by the service kit L68C-KIT and the option for quick-fill accessory 18-011-021. The closed-bowl design reduces contamination, and modular plug-in components support rapid serviceability. Combined with the lightweight aluminium construction, these features minimize downtime and extend service life, delivering measurable total cost of ownership improvements.
