Norgren L74C-4GP-QAN Excelon oil fog lubricator - G1/2
Part Number: L74C-4GP-QAN
Quick Summary
Excelon oil fog lubricator is designed to deliver precise oil misting in compressed air systems for pneumatic cylinders, air motors, and air tools. Operators often struggle with inconsistent lubrication, which leads to uneven wear and unplanned downtime. The Excelon family supports CE compliance and rugged protection for industrial environments, with options that align to IP-rated requirements where applicable. Inline or modular installation, paired with a consistent flow sensor, ensures a near-constant oil-to-air ratio, reducing waste and extending actuator life. This balance of reliability and flexibility translates to lower operating costs and improved uptime for automated lines.

Excelon L74C-4GP-QAN offers inline or modular installation, allowing you to configure lubrication for compact or expansive automation layouts. The flow sensor maintains a near-constant oil-to-air ratio across a wide range of flows, delivering predictable performance and reducing lubrication waste in high-demand tooling scenarios. With oil fog lubrication, heavier lubrication is achieved over short distances, ideal for large bore cylinders, air motors, and air tools, improving start-up reliability and tool life. The body and bowl are aluminium, providing robust, lightweight construction that withstands industrial environments while minimizing weight on control panels. A manual drain simplifies field maintenance, ensuring quick on-site servicing without tools or complex procedures. Operating from a maximum 17 bar inlet pressure and G1/2 port size, this unit fits a broad spectrum of line sizes and is compatible with Excelon accessories for modular expansion. The L74C-4GP-QAN supports integration with T74T-4GA-P1N shut-off valves, 4316-50 porting blocks, and universal mounting options, enabling scalable lubrication across multiple zones. Service kits such as L74M-KIT further simplify maintenance, helping to lower lifecycle costs and maximize uptime in production lines.

FAQs
Yes. The L74C-4GP-QAN is designed for either inline or modular installation and is compatible with Excelon accessories such as the T74T-4GA-P1N shut-off valve, 4316-50 porting block, and the Universal Bracket 4324-50. This flexibility enables scalable lubrication layouts across single or multiple zones, reducing retrofit time and enabling easier expansion of existing pneumatic systems.
Key specifications include a G1/2 port size, maximum inlet pressure of 17 bar, and a flow rate of 91 dm3/sec (193 scfm). The operating temperature range is -34 to 80 °C, with the lubricator designed for compressed air as the medium and oil fog lubrication as the lubrication method. These specs support reliable performance in demanding automation environments.
Absolutely. The Excelon L74C-4GP-QAN is intended for heavier lubrication over short distances, making it well-suited for large bore cylinders, air motors, and air tools. The integrated flow control and modular compatibility help ensure consistent lubrication delivery, improving cyclic performance, reducing tool wear, and enhancing overall production uptime.
The Excelon series is designed to meet applicable CE requirements and to be suitable for industrial environments that may require IP-rated protection. While exact certification specifics can vary by regional installation, these units are engineered to support standard compliance and rugged operation in many automated facilities.
The flow sensor maintains a near-constant oil/air ratio, reducing lubricant waste and preventing over- or under-lubrication that can cause wear and downtime. The manual drain and accessible components simplify routine maintenance, cutting service time and labor costs. Over the lifecycle, this translates to lower replacement parts spend and higher machine availability in production lines.
