EKR4000 - Electric air screw compressor 4,000 l/min / max. 10 bar (145 PSI) Copy

EKR4000 - Electric screw compressor with 4,000 l/min compressed air output from Dynaset

The DYNASET EKR electric screw compressor converts the electrical energy of a mobile machine, vehicle or ship into compressed air.

The EKR electric screw compressor is the ideal solution for anyone looking for a powerful, machine-integrated, electrically driven compressor for continuous use. This compact and robust device is specially designed for demanding 24/7 operation and is therefore ideal for pneumatic applications in electric mining machines, drilling rigs, agricultural machinery, construction machinery and maintenance vehicles. Seamlessly integrated into the machine, it utilises the existing battery as a power source and eliminates the need for a separate motor or inverter.

How does the electric screw compressor work?

The electric compressor is integrated into the electrical and cooling systems of a machine, vehicle or ship.

1. The electricity from the battery is fed to the integrated electric motor of the electric compressor.

2. The electric motor drives the compressor and generates compressed air.

3. The cooling system of the machine, vehicle or ship keeps the compressor at the optimum operating temperature.

4. The electric screw compressor can work around the clock as long as the battery is sufficiently charged.
