FAQs
The L73C-2GP-EPN is designed for both in-line and modular installation on compressed air lines. Connect the G1/4 port to the supply manifold, ensure the closed-bowl guide is correctly seated, and mount the unit so gravity aids drainage away from sensitive components. Use the included installation guide to align with your existing Excelon or Norgren modules for a seamless retrofit or new-build integration.
Key specs include a start point of 0.71 dm3/sec and a maximum flow of 38 dm3/sec (81 scfm). The maximum inlet pressure is 10 bar, and the medium is compressed air. These figures support reliable lubrication across varying demand while maintaining a near-constant oil-to-air ratio through the integrated flow sensor.
Yes. The Excelon design supports heavier lubrication over short distances, which is ideal for large-bore cylinders, air motors, and demanding pneumatic tools. Its oil fog type provides consistent lubrication where robust protection against wear is required, improving tool life and reducing maintenance in high-load pneumatic applications.
The L73C-2GP-EPN is designed with safety and reliability in mind, featuring a closed-bowl guard for operator protection and compatibility with standard Excelon components. While CE-compliant construction is typical for industrial pneumatics, always verify your region-specific certifications and consult the installation guide for any additional regulatory requirements related to your facility.
Maintenance is simplified by the closed-bowl design and guard, reducing contamination risks and leakage. The flow sensor ensures precise oil usage, cutting waste and lowering lubricant costs. In practice, users report lower tool wear and reduced downtime, resulting in a favorable ROI when deployed across automated lines or during line upgrades.
