FAQs
The L73C-3GP-ETN supports inline and modular installation using a G3/8 port, enabling straightforward integration into existing pneumatic circuits. Its Excelon design allows mounting close to cylinders or tools, reducing oil travel time and simplifying retrofits across multiple stations.
Key specs include a maximum inlet pressure of 10 bar, port size G3/8, and a flow of 38 dm3/sec (81 scfm) with a start point of 0.71 dm3/sec. The unit uses oil fog lubrication, designed for consistent oil/air ratios across a wide range of operating conditions.
Yes. The Excelon L73C is designed for heavier lubrication over short distances, making it suitable for large bore cylinders, air motors, and air tools. The closed-bowl design helps contain lubricant and reduce spray in sensitive environments.
Certification details are not listed in the provided data. Please consult the official datasheet or contact Norgren to verify CE, IP, or SIL applicability for your region and application requirements.
The Flow sensor maintains a nearly constant oil/air ratio, reducing oil waste and the need for frequent top-ups. Inline/modular installation minimizes downtime during changes, and the durable aluminium body with a polycarbonate bowl supports longer service intervals, contributing to lower total cost of ownership.
