This can lead to thousands of dollars in energy cost savings per year.


Our range of quality products include:

  • Fixed and variable speed rotary screw compressors
  • Reciprocating compressors
  • Portable diesel compressors
  • Air dryers
  • Coalescing filters
  • After coolers
  • Pressure vessels
  • Oil-Water separators
  • Condensate separators
  • Auto drains


Designing the right compressed air system is fundamental to maximising efficiency and reliability. This will lead to significant savings in energy over the life of the system. We are experts in engineering the right compressed air system talking into consideration.


A flexible compressed air system is critical to ensuring costs are minimised. Stringent installation procedures ensure pipe work is installed to exacting standards. i.e. leak free, minimal pressure drop and with future expansion in mind.

Compressed air where you need it on time and on budget.

Materials used include copper, mild steel, aluminium and PE (plastic).
