Our 2-stagecompression air compressors are ideal forpowering pneumatic tools and equipmentin automotive production lines, ensuringreliable and energy-efficient air supply fortire inflation, painting, and more.

2. Food & Beverage

Processing: Theprecision-controlled pressure range (8-13bar) and high airflow capabilities make ourcompressors perfect for food packagingbottle blowing, and other processesrequiring precise air control, maintaininghygiene standards with lP54-rated motors.3. Mining & Construction:

Durability and highperformance are key in mining andconstruction sites.Our compressorsdeliver consistent airflow(310-4240 cfm)to power drills, jackhammers, and otherheavy-duty equipment, enhancingproductivity and reducing downtime.

4. Textile Industry:

For textile mills, ourenergy-efficient 2-stage compressorsprovide stable air pressure for spinning,weaving, and finishing processesenhancing product quality and reducingoperational costs. The lP54 protectionkeeps motors safe from dust and debris,ensuring continuous operation.

Two-stage compression, energy saving up to 15% compared to single stage

1. Two-stage compression, small compression ratio, less leakage, small bearing load, greatly improved bearing life.

2. Unique intercooler jet curtain design reduces the temperature of the air and saves the power required for compression.

3. The design idea of "large rotor, large bearing, low speed" is adopted to reduce noise and vibration and increase the life and stability of the air end.

4. The tooth surface is processed by the German KAPP rotor grinder to create a high-precision rotor, which is the first guarantee of high efficiency and stability of the air end.

5. Adopt a new type of 5: 6 asymmetric rotor tooth shape, high-precision three-coordinate measuring machine for comprehensive measurement, increase the air capacity by 5% -10%.

6. All imported quality bearings are used.

Customized vector inverter

1. Professional customization, perfect match with motor;

2. Fully monitor the parameters of the motor, including the motor temperature, to reduce the risk of the high temperature of the motor;

3. Independent air duct design, strong environmental adaptability;

4. Quick response, the response time is less than 50mS

5. Large low frequency torque, can output 180% rated torque;

Silent centrifugal fan

1. The whole series adopts centrifugal fan, which is more efficient and more energy-saving.

2. Compared with axial fans, centrifugal fans have higher air pressure, lower noise and more energy saving.

3. Controlled by frequency conversion fan, the oil temperature is constant and the service life of lubricating oil is greatly extended.

4. Due to the high wind pressure, the cooler and filter are less likely to be blocked.
