Norgren L74C-6AP-QDN Excelon Oil Fog Lubricator - 3/4 in PTF
Part Number: L74C-6AP-QDN
Quick Summary
Norgren L74C-6AP-QDN Excelon oil fog lubricator provides precise oil-air lubrication for large-bore cylinders and air tools. Maintenance and installation can be challenging in inline systems, but the Excelon design supports either inline or modular mounting for flexible integration. Certifications to verify include CE marking and relevant IP protection on the bowl and body; check the datasheet for exact ratings. This solution delivers reliable, consistent lubrication across a wide flow range, helping minimize wear and downtime. The result is improved system reliability and lower total cost of ownership for pneumatic automation and tooling applications. It also leverages a flow sensor to maintain a nearly constant oil/air ratio as demand changes, a key advantage in production environments.

FAQs
This lubricator supports inline or modular installation and uses a standard 3/4 in PTF port, enabling straightforward integration into existing air lines. Compatible accessories include T74T-6AA-P1N shut-off valves, porting blocks, and mounting brackets to simplify manifold configurations and reduce commissioning time.
Review the operating medium as compressed air, the start point of 0.94 dm3/sec, flow capacity of 91 dm3/sec (193 scfm), maximum inlet pressure of 17 bar, and an operating temperature range from -34 to 80 C (-30 to 176 F). The oil fog type and metal/aluminium construction influence durability and lubrication quality.
Yes. The Excelon L74C-6AP-QDN is designed for heavier lubrication over short distances, which aligns with large bore cylinders, air motors, and air tools. Its flow characteristics and oil fog delivery support consistent lubrication where demands spike, while the flow sensor maintains a stable oil/air ratio.
Maintenance is simplified by a manual drain and a metal bowl with a liquid level indicator. Service kit availability is shown as L74M-KIT, and there are CAD files, datasheets, and installation guides available for maintenance planning and parts replacement to minimize downtime.
Durable aluminium body and bowl resist wear in tough environments, while the inline/modular installation reduces installation time and capital cost. A constant oil/air ratio minimizes oil consumption and wear on downstream components, lowering maintenance frequency and extending equipment life in automated pneumatic systems.
