SMT two-stage screw air compressors can save up to 30% energy compared with single-stage compression at the same delivered airflow and working pressure. Choose permanent magnet variable speed or fixed-speed operation without an inverter. Listed models cover 22–200 kW with IP55 motors; the wider two-stage supply range extends to 450 kW.

A CLOSER LOOK
Up to 30% energy savings with two-stage compression.
Two-stage compression can save up to 30% energy compared with single-stage compression at the same delivered airflow and working pressure. Savings depend on the selected compressors and operating load. The listed SMT models cover 22–200 kW, with IP55 motors and permanent magnet variable-speed or fixed-speed drive options.
Our wider two-stage supply capability extends from 22 to 450 kW. For an existing air station, share the operating pressure, demand pattern and current equipment details. A meaningful comparison considers delivered airflow and power at the same conditions, together with cooling, air treatment, maintenance access and the future production plan.
01 / MATEOU
Up to 30% lower energy consumption
Meet the same air-delivery requirement with less input power through two-stage compression. Compare the compressors at the same working pressure and operating conditions; actual savings depend on the selected equipment and load profile.
02 / MATEOU
IP55 motor configuration
The listed SMT models use IP55 motor protection. The installation still requires a suitable equipment environment, cooling airflow and electrical protection. Motor protection does not make the whole package suitable for unrestricted outdoor use.
03 / MATEOU
Permanent magnet variable speed / Fixed speed
Specify variable-speed control or fixed-speed operation without an inverter. Both options can be configured around the electrical supply and operating requirements of the destination market.
04 / MATEOU
Thick enclosure panels and acoustic insulation
Our enclosure panels are made from thick material conforming to Chinese national standards. The rigid panels help reduce resonance and provide stable support for the enclosure. Internal thermal and acoustic insulation lining helps reduce operating noise.
Application considerations
Discuss SMT for central air stations, multi-shift manufacturing and production lines with sustained air demand. The best choice depends on operating hours and demand variation, and can be reviewed alongside single-stage VSD equipment.
COMMON QUESTIONS
More detail before you decide.
Are the displayed models the full supply range?+
The online SMT selection covers 22–200 kW. Other two-stage configurations within the 22–450 kW supply range are available for discussion. Obtain model-specific performance, dimensions and electrical requirements for the proposed size.
Can I choose IP23 for an SMT model?+
The displayed SMT configurations use IP55 motor protection. Confirm the complete motor and electrical specification in the quotation; IP23 is not offered as a choice for these listed models.
What should an energy comparison include?+
Compare airflow and input power at the same pressure and reference conditions. Include load variation, unloading operation, operating hours and pressure losses through the existing system.
Is SMT available without an inverter?+
Yes. Choose permanent magnet variable speed or a fixed-speed configuration. The fixed-speed version has no inverter. Confirm the motor and electrical configuration for the destination market.
What does the 30% energy-saving comparison mean?+
The up-to-30% comparison refers to two-stage versus single-stage compression at the same delivered airflow and working pressure. It is separate from savings due to variable-speed control. Actual savings depend on the selected machines, working point and load profile.
