Built for continuous duty
All JAB compressors share the same basis: direct drive, efficient cooling and pressure lubrication. The cutaway shows a high-pressure model.

- Air filterOptimised for flow and sound, with high pre-separation and low pressure drop.
- Specially treated cylindersMinimum oil consumption, blow-by and wear.
- Direct driveMotor coupled directly to the compressor – no belt losses.
- Efficient coolingLow intermediate and outlet temperatures.
- Maintenance-free separatorsNo maintenance costs for the separators.
- Automatic condensate drainWithout additional solenoid valves.
- Quality crank-drive bearingsFor continuous, durable operation.
- Pressure lubricationWith oil-pressure monitoring for a long service life.
- Three-point mountingVibration-free, no foundation needed.
Gas version
- Gas-proof shaft seal – no leakage
- Pressure-tight crankcase, inlet pressure up to 40 bar
- Pressure switches instead of safety valves – no gas release and less tubing
JABcommand UNI plus
The controller monitors and protects the compressor, automates operation of the unit and simplifies service and maintenance.
- Error messages in full text and as classic codes, with a large error memory
- Yellow info LED signals service intervals (gaskets, shaft, pistons)
- As master control it monitors and operates one or several compressors
- Switches and push-buttons to EN 60204 for easy operation
- Rotating-field monitoring and potential-free contacts for integration into a control system
