Screw Piston Tandem Air Compressor
Screw piston tandem air compressor integrates a unique dual compression process where air, initially compressed by the screw compressor, undergoes a second stage of compression through a booster, enabling the system to achieve an outlet pressure of up to 4.0Mpa. This reliable oil-free and water-free compressed air system is used widely in industries like bottle blowing where such technologies are popular internationally due to their simplicity, reliability, and ease of maintenance compared to other mid-pressure systems.
- Free air delivery
8-15m³/min
- Discharge pressure
10-40MPa
-
Low noise and stable performance
The inherent stability of the screw compressor, combined with its fully enclosed connection to the booster, ensures low operational noise and stable performance, making it an ideal choice for settings requiring quiet operation.
-
Integrated system design
The entire system unifies a screw air compressor, booster compressor, air storage, and air purification into one compact skid-mounted unit. This design maximizes space efficiency and offers flexible installation options to accommodate different industrial environments.
-
Reliable oil-free, water-free compressed air
The screw piston air compressor system features air purification capabilities that ensure the processed compressed air has an oil residue level of ≤0.001PPM and a moisture content at a normal pressure dew point of -23°C, fulfilling stringent air quality standards.
The screw piston compressor is a versatile unit combining piston and screw compression technologies, known for its efficiency, energy savings, low noise, and smooth operation. It has become a mainstream choice in compressor technology, widely used in chemical processing, refrigeration, and aviation.
Features- The dual screw compressor and high-pressure piston compressor are interconnected and skid-mounted to a high-pressure air compressor system with a large capacity, powered by the dual motors for an enhanced operation.
- The dual screw and the high-pressure piston compressor are each independently powered by their own electric motors.
- Components such as coolers within the system are water-cooled. Air passes through the screw compressor, air-water separator, piston compressor, oil removal filter, and dryer to meet stringent user requirements for air quality.
- The units are mounted on a rigid base, creating a compact structure that is light in weight and occupies less space. The air compressor is equipped with an automatic control system for optimal performance.
