Norgren L74C-4AP-QAN Oil Fog Lubricator - Inline/Modular
Part Number: L74C-4AP-QAN
Quick Summary
The Norgren L74C-4AP-QAN oil fog lubricator provides controlled lubrication for pneumatic systems in industrial automation. In practice, engineers often struggle to maintain a stable oil-to-air ratio across fluctuating flows, leading to cylinder wear or tool contamination. Certification details such as SIL, CE, or IP ratings are not listed in the provided data and should be confirmed via the product datasheet. As part of the Excelon line, it supports inline or modular installation, delivering dependable lubrication with minimal maintenance, and it complements standard compressed air systems while offering scalable integration for growing production lines.

FAQs
What mounting options exist and how do you integrate the L74C-4AP-QAN with Excelon components? The unit is designed for inline or modular installations and is compatible with the Excelon 73/74 series ecosystem, including accessories like 4324-50 Universal Bracket and L74M-KIT service options to simplify mounting, plumbing, and future expansions. This supports rapid deployment in new lines or retrofits in existing plants.
The L74C-4AP-QAN employs an oil fog lubrication approach with a flow sensor that maintains a nearly constant oil/air ratio over a wide range of flows. This reduces variance in lubrication delivery, contributing to longer cylinder life and more consistent tool performance, even when workloads fluctuate during production cycles.
Yes. The Excelon L74C-4AP-QAN is designed to support heavier lubrication requirements over short distances, making it well-suited for large bore cylinders, air motors, and high-use air tools. With a 91 dm3/sec maximum flow and robust aluminum body/bowl construction, it provides reliable lubrication where demands are high.
Certification details such as SIL, CE, or IP ratings are not listed in the provided data. For regulatory compliance, consult the product datasheet (Datasheet PDF and Installation Guide referenced in the downloads) or contact Norgren to confirm current certifications and any region-specific requirements before deployment in regulated environments.
Maintenance and upgrade paths are supported by the L74M-KIT service kit and a range of mounting/accessory options (T74T-4AA-P1N, 4316-50, 4324-50, 4314-51, 4314-52, 4315-03). Regular service intervals, combined with these accessories, enable predictable uptime, easier spares management, and smoother upgrades within the Excelon modular system.
