Norgren L74C-3AP-QDN Oil Fog Lubricator - Excelon
Part Number: L74C-3AP-QDN
Quick Summary
Norgren L74C-3AP-QDN oil fog lubricator delivers precise lubrication for heavy pneumatic systems, including large-bore cylinders and air tools. Engineers often struggle to maintain a stable oil-to-air ratio with varying flow, leading to wear, contamination of downstream devices, and unexpected downtime. Excelon products are designed for inline or modular installation and are intended to perform reliably under up to 17 bar inlet pressure, with oil fog lubrication for short-distance carry. Certification details should be checked on the datasheet for regulatory needs; verify CE or SIL/IP compliance where applicable. This 3/8 inch ported lubricator with a manual drain integrates easily into automation lines, improving reliability and reducing maintenance costs in industrial automation.

Inline or modular installation enables flexible deployment in tight spaces, reducing installation time and plumbing complexity. This supports faster commissioning and lowers retrofit costs in new builds or upgrades across automated lines. The product is compatible with Excelon mounting accessories such as 4315-02 Quikmount pipe adapters and 4316-50 porting blocks, enabling organized, clean panel layouts. Oil fog lubrication provides heavier, controlled lubrication over short distances for large bore cylinders, air motors, and air tools. This reduces wear and extends tool life, delivering predictable lubrication in high-load cycles for compact tool stations and production lines. A flow sensor maintains a near-constant oil/air ratio across wide flow ranges, delivering stable actuation and reducing maintenance needs in variable-speed applications. Aluminium body and bowl offer durability and corrosion resistance, supporting long service life in harsh environments and simplifying maintenance with reliable mounting. Manual drain simplifies routine service operations, minimizing downtime during top-ups and inspections. The lubricator supports a broad operating envelope with a maximum inlet pressure of 17 bar and a temperature range of -34 to 80 °C, making it suitable for diverse plant conditions and environments across automotive, packaging, and general automation segments.

FAQs
The L74C-3AP-QDN supports inline or modular installation and works with Excelon mounting accessories such as the 4315-02 Quikmount pipe adapter and the 4316-50 porting block. This enables flexible placement in compact panels or retrofit scenarios, reducing installation time and plumbing runs. Ensure 3/8 in PTF port compatibility and secure mounting to maintain alignment and minimize vibration during operation.
Key specifications include a 3/8 in PTF port, manual drain, maximum inlet pressure of 17 bar, lubricator fog type of oil fog, and a flow rate of 91 dm3/sec (193 scfm). Start point is 0.94 dm3/sec, with operating temperatures from -34 to 80 °C. These figures support predictable lubrication in high-load pneumatic systems and provide guidance for system sizing and maintenance planning.
Yes. Excelon oil fog lubricators are designed for heavier lubrication over short distances, making them well suited for large bore cylinders, air motors, and air tools. The 3/8 in port size and durable aluminium body support reliable performance and longer tool life in demanding automation lines, especially where precise lubrication is critical for repeatable actuation.
Certification details are not listed in the provided data. Please consult the datasheet or product page that includes CE, SIL, and IP status to confirm regulatory compliance for your facility. Datasheet links are available (Datasheet PDF and Installation Guide) to verify applicable certifications.
Maintenance is streamlined by the manual drain and the availability of service kits for the Excelon line (L74M-KIT). For easier servicing and reduced downtime, consider mounting accessories such as the 4315-02 Quikmount and 4316-50 porting blocks to simplify top-ups and inspections, and ensure regular checks of the oil level and flow performance.
