VR40 VS VR70

VR40 VS VR70? What's the difference?

Techni systems mobile compressed air systems are the best choice for customers who need to save load space, reduce gross vehicle weight, increase payload and minimise maintenance requirements.

Here at Techni Systems we have two engine mounted systems, the VR40 and VR70, but what's the difference?

VR40VMAC VR40 Air Compressor

The VR40 is the lightest and most fuel efficient 40 CFM mobile air compressor available. It is the perfect choice for mobile tyre fitting and service / support vehicles. Its compact and powerful design is fully engineered to integrate into light commercial vehicles.

The VR40 saves on average 68.6% more fuel than competitor systems due to the systems ability to switch off when no air is being used and automatically restart once tools and air is required, lowering fuel consumption emissions and noise pollution.


Ideal for:

  • Commercial Tyre Fitting
  • Utilities
  • Forklift Repair
  • On-site Maintenance Vehicles


  • 1" Impact Gun
  • Tyre Inflation
  • Die Grinders
  • Light Chipping Hammers
  • Drills
  • Air Jack
  • Tyre Changer
  • Pneumatic Hand Tools


The VR70 is the most powerful, compact 70CFM mobile air compressor available on the market.

Delivering a constant 70CFM* and up to 175psi the VR70 is our fastest and most efficient compressor system.

Ideal for:

  • Industrial Tyre Fitting
  • Utilities
  • Heavy Equipment Repair
  • Sign Installation
  • Mobile Mechanics
  • Fibre Blowing
  • Cavity Wall Insulation


  • Impact Wrenches
  • Grinders
  • Road Breakers
  • Air Guns
  • Post Pounders
