Compact in design and easy to install; modular, allowing for flexible configuration; simple to maintain, with replaceable filter elements; effectively removes contaminants from compressed air, extending the service life of cylinders, valves, and pneumatic fittings while reducing the likelihood of malfunctions.
Key Technical Points
air service unit is a fundamental component for the initial purification and pressure regulation of a pneumatic system. Installed between the air compressor and pneumatic actuators (such as cylinders, pneumatic valves, and fittings), it purifies the compressed air, regulates its pressure, and removes moisture and oil. By ensuring the quality of the compressed air, it serves as an essential front-end unit for any pneumatic circuit.
Manufactured in accordance with the technical requirements of internationally renowned brands; suitable as a direct replacement.
Filters out moisture, dust, and solid impurities from compressed air, separates condensate, and protects downstream valves and cylinders, thereby reducing wear.
Provides a stable output pressure by regulating the fluctuating high-pressure compressed air from the air compressor down to the operating pressure required by the equipment; the pressure is adjustable, ensuring a constant pressure within the circuit.
Lubricating oil is atomized into the compressed air to lubricate the internal moving parts of pneumatic components; for oil-free pneumatic systems, the lubricator can be omitted.
Our primary product lines include series compatible with Festo, SMC, AirTAC, Sunnys, and CKD, as well as a range of high-pressure components manufactured domestically.
