Excelon Plus oil fog lubricator, G1/2, Metal bowl closed
Excelon design allows in-line or modular installation, enabling flexible integration with minimal downtime and simple retrofits in existing production lines, which translates to lower installation costs and faster time-to-value for manufacturers. The oil fog lubrication approach is ideal when heavier lubrication is required over short distances, such as large bore cylinders, air motors, and air tools, providing a protective film that reduces wear and extends component life while lowering maintenance frequency. A flow sensor maintains a nearly constant oil/air ratio across a wide flow range, delivering process stability, reduced lubricant waste, and improved predictability for QA and uptime reporting on high-demand lines. With a G1/2 port, aluminium body and bowl, and a closed-bowl drain, the unit combines durability with clean, maintenance-friendly operation suitable for demanding industrial environments and space-constrained installations. The L73C-4GP-EDN also offers compatibility with CAD downloads and installation guides, simplifying engineering workflows and accelerating projects from concept to commissioning. Industry teams benefit from clear performance metrics—flow up to 38 dm3/sec (81 scfm), start point at 0.71 dm3/sec, and a maximum inlet pressure of 17 bar—supporting reliable operation in a wide range of pneumatic systems and production scales. The combination of robust materials, modularity, and sensor-driven control helps address common objections about oil consumption, mess, and maintenance burden, delivering a cost-effective, compliant lubrication solution for automation cells and tooling suites.

FAQs
The L73C-4GP-EDN is designed for simple in-line or modular installation on compressed air lines with a standard G1/2 port. Begin by shutting down the segment, attach the lubricator in the correct orientation to ensure oil flow toward the downstream components, and secure the closed-bowl assembly. Use the provided CAD drawings to confirm mounting clearances and avoid vibration transfer. After installation, confirm the flow sensor is calibrated for the target line and perform a brief ramp-up test to verify oil/air ratio stability across the intended operating range. This minimizes startup waste and ensures predictable lubrication performance.
Key specs include medium as compressed air, port size G1/2, closed bowl drain, maximum inlet pressure of 17 bar, and lubricator type oil fog. Flow capacity is 38 dm3/sec (81 scfm) with a start point at 0.71 dm3/sec. Materials are aluminium for both body and bowl, with elastomers in chloroprene and nitrile. These figures support reliable lubrication over a broad operating range and compatibility with common pneumatic components and actuation hardware.
Yes, the Excelon L73C-4GP-EDN is specifically intended for situations requiring heavier lubrication over short distances, which suits large bore cylinders, air motors, and air tools. The oil fog approach delivers a protective lubricant film that reduces wear and maintains performance under high-demand conditions. Its in-line or modular installation helps integrate with existing tooling and automation cells without extensive reconfiguration.
In the field, Excelon lubricators are commonly associated with CE conformity and robust enclosure protection, which support compliance in many regional markets and harsh environments. While product-specific certification details should be confirmed for your region, you can expect the L73C-4GP-EDN to align with industry standards for safety, reliability, and environmental tolerance, making it a viable choice for integrated pneumatic systems in manufacturing and processing facilities.
The L73C-4GP-EDN delivers a predictable oil/air ratio via its flow sensor, reducing lubricant waste and allowing for more accurate maintenance planning. The closed-bowl design minimizes oil splash and contamination, lowering cleaning costs and downtime. With modular installation and durable aluminium construction, it reduces replacement frequency and support costs across OEM lines and aftermarket service programs, improving overall equipment efficiency and asset reliability.
