FRL Maintenance Unit 3/4" | Aignep

The AIGNEP Standard Series FRL 3/4" Maintenance Unit is a complete compressed air conditioning unit that integrates a shut-off valve, filter, pressure regulator, lubricator, and pressure gauge into a single assembly. Designed for higher flow lines than the 1/2" version, it ensures that the air supplying pneumatic equipment arrives clean, at constant pressure, and properly lubricated, extending the service life of valves, cylinders, actuators, and pneumatic tools. Manufactured in Italy by AIGNEP, it operates within a pressure range of 0 to 8 bar with a 3/4" BSPP connection. Available with 5 or 20 micron filters depending on the required purity level.

Applications

• Compressed air conditioning in higher flow lines (3/4") in industrial plants
• Protection of pneumatic valves, cylinders, and actuators against contaminants and moisture
• Stable pressure regulation in systems with fluctuations in the main line
• Automatic lubrication of pneumatic tools and actuators with moving parts
• Manufacturing industry, assembly, and high-demand industrial automation
• Food and pharmaceutical industry (with 5 micron filter for greater purity)
• Centralized pneumatic systems with multiple consumption points
• Any 3/4" pneumatic system requiring clean, regulated, and lubricated air
