1. Features of Sollant Two-stage compressor:

(1). Two-stage compression reduces the compression ratio of each stage, reduces internal leakage, improves volumetric efficiency, reduces bearing load, and increases the life of the host.
(2). Two-stage PM VSD replaces single-stage compression, and the displacement is increased by nearly 15%, which can achieve an additional 15% energy saving effect.
(3). The rotor adopts the latest patented rotor UV profile, which has been refined by more than 20 procedures to ensure the accuracy, reliability, and effectiveness of the rotor profile.
(4). Two-stage PM VSD air compressor mainframe is more efficient and more energy-saving. It can save up to 40% energy compared with ordinary industrial frequency machines. Calculated at 8000h/unit/year, it can save electricity costs 30,000 USD per year.


2. Advantages of Sollant Two-stage compressor:

2 stage air compressor

(1). More Energy Efficient
A two-stage PM VSD rotor is directly driven through the gears, and each stage of the rotor can obtain the best speed. The Air end is always running at the best energy-saving speed. The frequency conversion soft-start reduces the energy consumption of the air compressor during startup. By controlling the pressure between stages, the compressor always works at the best efficiency point under different working conditions. Compared with a single-stage fixed-speed air compressor, in principle, a two-stage PM VSD air compressor can save 40% energy.

(2). More Stable
There is no mechanical transmission failure, the motor, and the male rotor adopt an integrated shaft structure, and there is no need for coupling and gear transmission, eliminating the hidden danger of coupling and gear failure.

(3). More Efficient
PM VSD motor+ no transmission efficiency loss.
PM VSD motor has the advantages of energy-saving and excellent performance.
The one-piece structure can reduce the efficiency loss of coupling and gear.

(4). More Comfortable
Low noise and low vibration. No motor and bearing noise, no gear noise, no coupling noise.

(5). More Compact
The PM VSD motor is small in size, and the integrated structure saves space.
