FAQs
The L72C-2GP-QLN is designed for both inline and modular installation in compressed air systems. Its G1/4 port size and robust zinc body support straightforward integration with standard fittings and manifolds, enabling quick upgrades to existing lines and scalable installations across machines. In practice, this reduces commissioning time and minimizes disruption during retrofits.
The lubricator delivers oil fog within a specified flow of 24 dm3/sec (51 scfm) with a start point at 0.47 dm3/sec, ensuring a nearly constant oil-to-air ratio across a wide flow range. This steady ratio improves lubrication consistency, protects moving parts, and reduces variation in tool performance across different operating speeds and loads.
Yes. The Excelon design is intended for heavier lubrication over short distances, making it well-suited for large bore cylinders, air motors, and air tools. The oil fog approach provides durable lubrication where higher oil volume is required, helping to extend component life and reduce maintenance frequency in demanding applications.
The product line commonly aligns with CE compliance and ISO-quality management practices, supporting safe and reliable operation in European markets and global manufacturing environments. Specific IP or SIL ratings are not listed in the provided data, so consult the datasheet or manufacturer for exact regulatory declarations for your use case.
Maintenance is simplified by a manual drain and a durable construction with a zinc body and polycarbonate bowl, facilitating field service and level checks. ROI benefits arise from extended tool life, reduced downtime, and lower maintenance labor due to straightforward access and predictable lubrication performance in inline systems.
