SM single-stage rotary screw air compressors use permanent magnet variable speed drive to follow changing factory air demand. Listed models cover 7.5–220 kW, with IP23 or IP55 motor protection and ZONCN or INOVANCE inverters. Separate receivers, refrigerated or desiccant dryers and precision filters can be selected for the air station.
Air delivery, motor power and component options are confirmed for the model quoted. Energy savings depend on the application and operating conditions.
A CLOSER LOOK
Flexible air supply for changing production demand.
The SM series combines single-stage screw compression with a permanent magnet variable speed drive. It suits factories where air demand changes during the day. The compressor, receiver, dryer and filters can be placed separately to fit your workshop.
The online range covers SM-10A to SM-300A, from 7.5 to 220 kW. Compare the air-delivery row at your required working pressure: the same motor power does not deliver the same airflow at every pressure. Other single-stage sizes within our 7.5–280 kW supply range can be discussed for larger installations.
01 / MATEOU
Variable speed operation
The drive adjusts motor speed within its operating range as air demand changes. Selection should take account of minimum demand, peak demand and daily running hours. Any energy comparison needs the actual load profile and operating pressure.
02 / MATEOU
A configurable air station
Pair the compressor with a receiver and an appropriately sized dryer. Add filtration according to the process requirements. This arrangement is useful when equipment must be placed separately or a production line is likely to expand.
03 / MATEOU
Components you can specify
Mainly BAOSI screw airends, with HANBELL or Torin Drive (Tongrun) available on request. Specify Jiangtian permanent magnet motors, IP23 or IP55 protection, and ZONCN or INOVANCE inverters to suit the installation.
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
Suitable applications include pneumatic production equipment, packaging, general fabrication and workshops with variable air use. Check ambient temperature, ventilation and the distance to the point of use when planning the installation.
COMMON QUESTIONS
More detail before you decide.
How do I choose between SM and an integrated package?+
Choose SM when you want a separate air station or already have a receiver and air treatment equipment. An SZ integrated package brings these functions together for a compact installation. Compare the complete equipment scope and the space available.
Does VSD always give the same energy saving?+
No fixed saving percentage applies to every installation. The result depends on the demand pattern, operating pressure, control settings and how the current compressor runs. Share these details so the proposed configuration can be assessed.
Are larger single-stage compressors available?+
Yes. The displayed SM models cover 7.5–220 kW, while the wider single-stage supply range extends from 7.5 to 280 kW. Ask for the specific performance and dimensions of the size you need.
