Oil-Free Screw Air Compressor

Industry-Leading Original Oil-Free Air End

The compressor features a specially designed oil-free air end with separate air compression and oil chambers. The air chamber uses a stainless-steel, spring-loaded metal-ring sealing system, while the oil chamber incorporates a copper labyrinth seal. This arrangement keeps the two chambers separate and helps prevent lubricating oil from entering the compressed-air path.

The second-stage rotor is manufactured from stainless steel to improve resistance to corrosion caused by moisture remaining in the compressed air after first-stage cooling. This design supports reliable operation and durability under demanding industrial conditions.

UITRACOAT protective coating is applied to the rotor and inner compression-chamber surfaces. It is designed to provide corrosion resistance, maintain close operating clearances and reduce the risk of coating deterioration. This helps support consistent air delivery over the compressor's service life.

Filtered lubricating oil is used to cool the air-end enclosure compartment, helping dissipate heat while avoiding scale formation associated with water cooling in that compartment.

Smart Electronic Control System

The intelligent electronic control system features a large, full-colour LCD touchscreen with a user-friendly human-machine interface. The control software is designed to work with the motor and compressor configuration, providing clear operating information and convenient access to machine settings.

The controller monitors key operating parameters and manages compressor operation according to configured settings. This helps operators track equipment status, identify operating abnormalities and simplify routine supervision. An independent air-duct design supports suitable airflow management under different operating conditions.

Independent Air Intake System

The independent air-intake arrangement draws air from the surrounding environment, helping keep intake-air temperature close to ambient temperature when installed and ventilated correctly. A large-capacity air filter provides effective filtration to help protect internal components from dust and airborne contaminants.

The optimized intake design helps reduce pressure losses and supports efficient compressor operation. The filter arrangement also allows convenient inspection, maintenance and replacement, helping reduce routine servicing effort.

Noise-Reduction Sheet Metal Enclosure

The enclosure incorporates a noise-reduction design developed around acoustic-control principles. Special flame-retardant acoustic insulation is installed inside the sheet-metal panels to help absorb equipment noise and reduce sound transmission.

This sound-control arrangement helps create a more comfortable working environment around the compressor, making it suitable for industrial facilities where noise management is an important consideration.

Efficient Shell-and-Tube Water Cooler

The compressor's cooling system uses a shell-and-tube heat exchanger with threaded finned tubes and a specially designed copper tube bundle. Compressed air flows through the tube side, while cooling water circulates through the shell side. This arrangement supports effective heat transfer and dependable cooling performance.

Enhanced heat-transfer performance: The finned-tube arrangement improves heat-transfer characteristics while helping manage pressure drop through the cooler. The shell-side baffles increase water-flow turbulence, supporting effective heat exchange and helping reduce conditions that encourage deposits on heat-transfer surfaces.

Durable and corrosion-resistant construction: Stainless-steel components on the compressed-air side help resist corrosion associated with elevated temperatures and pressure. The robust tube arrangement is designed for dependable service under the specified operating conditions.

Convenient maintenance: The heat exchanger follows a conventional shell-and-tube installation arrangement. Its removable tube bundle allows easier access for inspection, cleaning and maintenance, helping simplify servicing and manage lifecycle costs.

Reliable operation: Separating compressed-air flow from cooling-water flow helps support controlled heat exchange. The design also helps limit noise associated with compressed-air flow through the cooling assembly.

Venturi Noise-Reduction Silencers

The first- and second-stage air ends incorporate specially developed Venturi-type silencers to help control airflow noise. An integrated reactive and absorptive silencing arrangement further helps reduce noise generated by compressor airflow and connected piping.

This multi-stage noise-control design supports quieter operation while maintaining the airflow requirements of the compressor system.

Reliable Hydraulic Intake Valve

The high-efficiency intake valve uses hydraulic actuation to provide controlled and stable valve operation. The hydraulic arrangement is designed to support dependable intake regulation and reduce reliance on frequently serviced pneumatic components.

By simplifying the intake-control arrangement, the system can help reduce routine component replacement, maintenance requirements and avoidable equipment downtime.

Engineered Design Margins for Reliable Operation

The air filtration and cooling systems are designed with a stated 30%–50% capacity margin to help accommodate variations in operating conditions and maintain suitable performance when correctly selected for the application.

The electrical system is designed with a stated 10%–15% margin to accommodate specified operating requirements and certain variations in load conditions. These design allowances support operational flexibility when the compressor is selected, installed and operated within the manufacturer's recommended limits.
