Excelon Plus oil fog lubricator, G1/4, Metal bowl closed
Excelon design allows in-line or modular installation, accelerating setup and expanding where lubricators can be placed along a line. The business impact is faster commissioning, fewer integration steps, and smoother capacity planning for pneumatics networks. In practice, engineers deploy L73C-2GP-QDN adjacent to large-bore cylinders and air tools to simplify maintenance and ensure steady lubrication across zones. This lubricator uses oil fog delivery to provide heavier lubrication over short distances, ideal for large bore cylinders, air motors, and pneumatic tools. The resulting lubrication profile mitigates binding and wear, extending tool life and reducing cycle times in high-load applications. A built-in flow sensor maintains a nearly constant oil-to-air ratio across a broad flow range, ensuring consistent performance from idle to peak demand. This reduces wasted lubricant and minimizes drift in lubrication levels, delivering cost savings and better process stability in automation lines. Aluminium body and bowl provide rugged durability in factory environments, with a robust design that resists corrosion and impact. The metal bowl and reliable elastomer seals support long service intervals, while manual drain keeps maintenance simple and predictable. The L73C-2GP-QDN is part of the Excelon range, designed to integrate with standard Norgren components and existing piping (G1/4). Its inline or modular fit aligns with common pneumatic circuits, enabling scalable lubrication networks and straightforward retrofits without costly reworks.

FAQs

To install, mount the lubricator beside the pneumatic line, connect the G1/4 port to the compressed air supply, and ensure proper orientation for gravity-assisted drainage. The Excelon design supports both inline integration and modular expansion, enabling rapid deployment along existing lines or in new jury-rig-free configurations. After installation, perform a purge/bleed using the manual drain to verify oil flow and system seal integrity.
Key specs include a flow rating of 38 dm3/sec (81 scfm), a start point at 0.71 dm3/sec, and a maximum inlet pressure of 17 bar. It uses oil fog lubrication and has a G1/4 port. The body and bowl are aluminium, with a operating temperature range of -34 to 80 °C. These figures support consistent oil-air mixing and reliable lubrication across varying demand in pneumatic lines.
Yes. The Excelon oil fog approach delivers heavier lubrication over short distances, which is well-suited for large bore cylinders, air motors, and heavy pneumatic tools. This supports reduced stick-slip, improved tool response, and longer component life without over-lubricating the downstream pipe network.
Maintenance involves monitoring the metal bowl and elastomer seals for wear, performing routine drain and refill via the manual drain, and ensuring the flow remains within spec. The design simplifies service with accessible components and predictable maintenance intervals, minimizing downtime and supporting consistent lubrication across shifts.
Verify CE conformity, relevant IP protections, and SIL considerations when integrating into safety-critical lines. Check compatibility with your compressed air supply, ambient conditions (-34 to 80 °C), and G1/4 piping. The L73C-2GP-QDN’s aluminium construction and Excelon platform support reliable operation across standard automation networks.
