FAQs
The Excelon L73C-3GP-QPN supports in-line installation or modular mounting, enabling seamless integration into existing pipelines and compact layouts. With a G3/8 port and a 10 bar maximum inlet pressure, it accommodates a wide range of plant configurations. The guarded bowl design also enhances safety during routine maintenance and service checks.
Key specs include a flow of 38 dm3/sec (81 scfm), a start point of 0.71 dm3/sec, and a maximum inlet pressure of 10 bar. The medium is compressed air, suitable for typical industrial pneumatic circuits, and the unit uses a G3/8 port with a manual drain for straightforward maintenance.
Yes. The Excelon oil fog lubricator is designed to deliver heavier lubrication over short distances, which benefits large bore cylinders, air motors, and air tools. The integrated flow sensor maintains a consistent oil/air ratio, supporting reliable tool performance and extended equipment life even in high-demand applications.
Maintenance is straightforward due to the manual drain and durable materials. The aluminium body plus polycarbonate bowl offer durability, while the elastomers provide compatibility with standard lubricants. Regular checks should include drain operation, bowl condition, and elastomer wear, with references to CAD/Datasheet resources for replacement parts and installation guidance.
