KAESER i.Comp 3 – The mobile oil-free compressor for tradespeople with i.Comp Control control system

The KAESER i.Comp 3 is reliable, efficient, and compact, making it the ideal oil-free reciprocating compressor for construction sites, workshops, and mobile applications. With a constant pressure of 11 bar and a flow rate of 160 l/min at 6 bar, this compressor is perfectly suited for a wide range of applications.

Advantages of the i.Comp 3 at a glance

  • without compressed air tank
  • Oil-free, therefore no oil changes or refills necessary
  • No oil-contaminated condensate is produced, as this evaporates automatically.
  • Digital pressure setting via the i.Comp Control control system
  • Up to 160 l/min flow rate at 6 bar
  • Up to 117 l/min at 11 bar
  • Long-lasting performance without loss of power

What distinguishes the i.Comp 3 from other piston compressors?

The KAESER i.Comp 3 is an oil-free reciprocating compressor that enables environmentally friendly compressed air production and eliminates maintenance tasks such as oil level checks or the removal of condensate. With its innovative drive concept, the i.Comp 3 automatically adapts to the current air demand and does not require a compressed air receiver, making it lighter and more mobile than many conventional models, which often rely on compressed air receivers and are therefore heavier and less mobile. In addition, the i.Comp 3 uses an advanced design for air intake via the piston base, which allows for larger valve cross-sections and thus a higher filling degree and lower compression temperatures. The i.Comp Control control system offers another advantage: it is user-friendly and allows digital pressure adjustment via arrow keys, whereas other compressors still require the pressure to be set using a pressure switch. Overall, the i.Comp 3 is characterized by its high efficiency, ease of use, and flexibility, which make it particularly suitable for changing locations in trade and industry. 

Versatile applications for your everyday work

The i.Comp 3 is much more than a compressor for craftsmen. Thanks to its versatility, it is suitable for numerous applications in crafts, interior design, and industry, such as

  • Painting wood and metal
  • Fast and even silicone jointing
  • Removing floor coverings
  • Stapling of films, nets, and fabrics
  • Compressed air filter cleaning
  • Cable blowing during fiber optic installation
  • Laser cutting with 10–11 bar working pressure
  • Pressure maintenance in containers for remote water supply

Intelligent control with i.Comp Control

The i.Comp Control control system, specially developed by KAESER Compressors for the i.Comp 3, enables precise regulation of pressure and power according to demand. The control system detects the actual pressure in the system and automatically adjusts the motor speed. The pressure can be easily adjusted to the desired maximum pressure using the arrow keys.
