ZF’s Commercial Vehicle Solutions (CVS) division has introduced a cutting-edge air compressor model designed for hybrid, battery-electric, and fuel cell trucks, buses, and coaches. The new e-comp Scroll was unveiled at two major industry events: the Advanced Clean Transportation (ACT) Expo in California, USA, and Auto Shanghai in China.
The e-comp Scroll is an oil-free, low-noise, and minimal vibration air compression system that combines operational efficiency with smooth performance. This new product reflects ZF’s commitment to advancing technology for zero-emission vehicles while addressing key industry demands for reduced noise and enhanced reliability.
The air compressor operates using an integrated electric motor and utilizes interlocking scrolls to compress air. This unique design helps minimize vibrations and ensures noise emissions remain at around 67dB(A) during standard operation—roughly equivalent to the quiet sound levels found in an office environment. The system is capable of reaching up to 12.5 bar of system pressure in a single stage and is adaptable to varying speeds to meet the specific demands of each application. Additionally, it includes an inverter and a liquid cooling shell to keep the discharge temperature below 90°C (194°F), enhancing its durability and performance.
In a separate announcement, ZF revealed that it has secured an order for several thousand AxTrax 2 units for intercity e-buses in India. Despite reporting a €41.4 billion sales figure for fiscal year 2024, reflecting an 11% decline from the previous year, the company continues to focus on its transition to zero-emission solutions. In February 2025, it was reported that ZF is exploring the possibility of spinning off its Electrified Powertrain Technologies division as part of a project called “Verde.” This move, however, will not affect the Commercial Vehicles division.
Paweł Porczyński, Head of Product Line for ZF CVS, emphasized the significance of the e-comp Scroll in helping to meet zero-emission targets for electric vehicles. He highlighted its low maintenance and energy-saving features, which contribute to a lower Total Cost of Ownership (TCO). Furthermore, the compressor’s design enhances the driving experience by reducing noise and vibration, benefiting both drivers and passengers while supporting the broader industry shift toward sustainable, zero-emission commercial mobility.
