Features a dual-rotor design to lower the compression ratio per stage. This significantly reduces internal leakage and increases air delivery by 15% compared to single-stage models.
Efficiency: Isothermal compression effect
Durability: Lower bearing load, longer life
Result: More air for the same power
Equipped with a genuineWEG IE4 motor(Brazil). The perfect match for the two-stage air end, ensuring the entire system operates at peak efficiency.
Protection: IP55 Dust & Water Proof
Insulation: Class F (B-level temp rise)
Quality: Global warranty & support
Combined with Two-Stage technology, the VSD inverter further reduces energy costs by eliminating unload power consumption.
Range: 5-60Hz wide regulation
Precision: Constant pressure ±0.01 MPa
Utilizes SKF bearings for both motor and air end. Two-stage design means lower load per bearing, extending life beyond 50,000 hours.
Reliability: Reduced axial/radial forces
Maintenance: Longer service intervals
Inter-stage cooling spray curtain design lowers the suction temperature of the second stage, approaching isothermal compression.
Efficiency: Closer to ideal compression
Design: Independent fan control
