Direct Coupled Compressor
Highlighted Features
- High efficiency with direct drive
- Elimination of belt-pulley losses
- Low maintenance cost
- Quiet operation
- Compact structure
Product Detail
Direct-coupled compressors transfer motor power directly to the screw unit, providing more efficient and stable operating performance. They increase energy efficiency by eliminating power losses caused by belt-pulley systems.
Models and Technical Information
Direct-coupled compressors offer a reliable compressed air solution for industrial businesses with their compact body structure, low maintenance requirement and quiet operation advantage. Since they do not require transmission elements such as belts and pulleys, they reduce maintenance costs.
Technical Advantage
Thanks to the direct drive structure, mechanical losses are minimized and the compressor operates with higher efficiency.
Technical Specifications
Technical specifications can be evaluated according to direct-coupled compressor models based on capacity, pressure, motor power and air flow values.
