Precision, stability, high pressure resistance, and fine adjustment — the FESTO series air preparation units are a premium choice for high-quality air treatment. Suitable for applications from 1.2 to 1.6 MPa, they offer strong pressure resistance to meet both standard and high-pressure industrial requirements. Fokca’s FESTO series air preparation units are made from high-strength die-cast zinc alloy and manufactured through fully automated precision machining, ensuring high dimensional accuracy and excellent sealing performance. The precision adjustment mechanism provides smooth and responsive regulation, enabling accurate control of both pressure and lubrication. Multiple configuration options are available, including filtration accuracy, drain type, pressure regulation range, and valve body material, allowing flexible adaptation to various automation systems.
A FESTO series air preparation unit typically consists of an air filter, regulator, and lubricator. Its function is to process compressed air from the air compressor through three stages—filtration, pressure regulation, and lubrication—to deliver a “clean, stable, and lubricated” air supply to downstream actuators such as cylinders, valves, and pneumatic tools. This helps extend equipment lifespan, ensure operational stability, and improve product quality.
Fokca’s FESTO series air preparation units are known for precision manufacturing, high pressure resistance, and sensitive adjustment performance. The product range includes the OU series FRL units, OFR series filter regulators, OF series air filtesr, OR series regulators, and OL series lubricators, providing high-performance and cost-effective air solutions for automation equipment.
