Product Description

The EV oil-free scroll air compressor is a core air supply component developed specifically for new energy commercial vehicles (electric buses, electric heavy trucks, electric light trucks, and fuel cell vehicles). It provides 100% oil-free clean compressed air for vehicle pneumatic braking systems, air suspensions, pneumatic doors, and other pneumatic equipment, replacing the direct-drive air compressor in gasoline-powered vehicles. Utilizing the scroll compression principle, with an integrated design of the motor and driver, the entire unit is compact, low-noise, low-vibration, and requires no oil maintenance.
