Electric screw compressor – efficient compressed air for hybrid and electric vehicles

Hybrid and electric vehicles are increasingly popular solutions in local public transport. This is especially true in the zero-emission zones of inner cities. Being noticeably quieter than comparable piston compressors, Knorr-Bremse's electric screw compressor is the perfect match for alternative-drive vehicle concepts.

Compressed air functions in electric and hybrid vehicles

Hybrid or all-electric vehicles also control a variety of components using compressed air. Alongside the brakes, these include the door opening and closing mechanism in buses and the levelling control in the chassis. An efficient, quiet and highly reliable compressed air supply is therefore also vital for hybrid and electric commercial vehicles.

More air, longer service life

Compared to the piston compressors commonly used in diesel vehicles, the electric screw compressor delivers an above-average volume of compressed air. By virtually eliminating oil carry-over into the compressed air system, it ensures low wear and a long service life of the desiccant cartridges. Moreover, it works without a crankshaft, which is also beneficial in terms of wear and weight.

Less vibration, improved sound profile

Because of its design, the screw compressor causes significantly less vibration than a piston compressor. This makes for quieter and more pleasant operation and helps to minimize unwanted noise emissions.

Key benefits:

• Suitable for electric and hybrid vehicles
• High compressed air output
• Favorable sound profile
