FAQs

The L73C-2AP-ETN supports both inline and modular mounting. Install after the filter-regulator in the air line, connect 1/4" PTF tubing to the port, and ensure the bowl is correctly sealed and oriented for gravity drainage. The closed-bowl design minimizes contamination, while the compact footprint suits tight spaces and multi-point lubrication schemes.
Key specs include a maximum inlet pressure of 10 bar and a flow of 38 dm3/sec (81 scfm). The unit offers a start point at 0.71 dm3/sec, an operating temperature range of -34 to 50 °C, and oil fog lubrication. These characteristics support stable oil delivery across variable pneumatic loads, including larger cylinders and tools.
Yes. The Excelon design provides heavier lubrication over short distances, which is advantageous for large bore cylinders, air motors, and air tools. Its oil fog approach maintains a near-constant oil-to-air ratio across the flow range, improving wear life and tool longevity in demanding applications.
The Excelon oil fog lubricator line is aligned with common industry standards, including CE compliance for European markets and enclosure protection suitable for many industrial environments. Always verify the specific configuration with your regional supplier to ensure adherence to local regulatory requirements and customer safety standards.
ROI stems from reduced wear, lower maintenance frequency, and controlled oil consumption. By delivering a stable oil fog across a broad flow range and enabling inline or modular installation, the L73C-2AP-ETN minimizes downtime on large-bore cylinders and tools, improving production uptime and overall system reliability.
