Compact Air Compressors


With more than 30 years of supplying and supporting general industry with a comprehensive range of compact and portable air compressors, Kaishan Australia can offer the best advice on the selection of the right compressor to fit your application.

Scroll Orbit Air Compressor
4 – 15 kW

The OX series of compact lubricated scroll air compressors meet today’s demands from industry to reduce energy costs, improve reliability and provide a safe working environment. Scroll technology is an advanced alternative to reciprocating air compressors.

The advanced, lubricated ‘Scroll’ technology offer energy efficiency with minimal moving parts in an ultra-quiet, compact package.

With the added benefit of continuous load capability and an integral aftercooler to reduce moisture carry over, the Scroll range offers a reliable compressed air supply with lower energy bills.


  • Maximum output for the power you put in.
  • 100% continuous duty rated – no need to oversize the compressor to manage operating temperatures or load cycle.
  • Direct drive means zero transmission losses.


  • Dynamically balanced, non-contact orbital scrolls result in ultra quiet performance that won’t disrupt your work environment.
  • Noise levels: 57-62dB(A) +/- 3dB(A)


  • Integral aftercooler to reduce liquid condensate.


  • Minimal floor space required for installation.


  • Periodic replacement of filters and lubricant.
  • Direct drive means no drive belts to replace.


  • WEG direct drive motor
  • MEPS II compliant
  • Starting method: DOL (staged for 15kW)
  • Dynamic 3D balanced scrolls
  • Coutershaft-bearing precision alignment
  • Fixed-orbit Scroll technology
  • Temperature and overload protection
  • Maximum ambient temperature: 50°C
  • Power supply: 415V / 3ph / 50Hz

Compact Rotary Screw Air Compressors

5.5 – 15kW

Kaishan krst series receiver mounted compact rotary screw compressors are the ideal package for industries requiring high performance from a small footprint compressed air unit. These compressors are designed to be easily installed whilst producing maximum output with outstanding reliability. Engineered from the highest quality components, utilising the latest in compressed air technology, every compressor is mounted on a 500 litre air receiver with an optional refrigerated dryer and coalescing filter to produce outstanding air quality. The Kaishan krst range offers capacities from 0.55 m³/min to 2.35 m³/min and are suited to a diverse range of applications.
