ZF’s Commercial Vehicle Solutions (CVS) division has launched a new air compression system specifically engineered for electrified commercial vehicles. The e-comp Scroll, unveiled at the Advanced Clean Transportation (ACT) Expo in California and Auto Shanghai in China, is designed to provide efficient, oil-free, and low-noise air compression for medium and heavy-duty hybrid, battery-electric, and fuel cell trucks, buses, and coaches.
Compressed air remains essential in commercial vehicle applications, supporting systems such as air disc brakes, suspension, and auxiliary functions. Unlike conventional internal combustion engine-powered vehicles, where compressors are mechanically driven, electric commercial vehicles rely on independently powered electric air compressors. This change introduces new requirements for noise and vibration control.
The e-comp Scroll addresses these requirements by utilizing scroll technology—interlocking spirals that compress air in a smooth, continuous motion. This mechanism substantially reduces vibration and limits operational noise to approximately 67 dB(A) at a flow rate of 250 liters per minute, a level comparable to that of a typical office environment.
Paweł Porczyński, Head of Product Line, Chassis Solutions, ZF CVS, stated, “The e-comp Scroll represents a strategic advancement in support of zero-emission vehicle targets. Its oil-free design reduces environmental impact, eliminates oil-related maintenance, and lowers total cost of ownership. Energy consumption is further optimized through automatic shutdown between compression cycles.”
Equipped with a built-in electric motor, the system can generate up to 12.5 bar of pressure in a single stage and operate at variable speeds according to demand. It incorporates an integrated inverter and a liquid-cooled shell, ensuring the discharge temperature remains below 90°C (194°F). By delivering quiet, efficient, and environmentally responsible air compression, the e-comp Scroll strengthens ZF’s portfolio of electrification technologies and supports the commercial vehicle sector’s transition to sustainable mobility. ZF is a global technology leader in driveline, chassis, and active and passive safety systems, serving the automotive, commercial vehicle, and industrial technology sectors.
Headquartered in Friedrichshafen, Germany, ZF is driving innovation in electrification, automation, and digitalization to shape the future of mobility.
