Oil Piston Air Compressor For Air Suspension System
Product Description
Electric air compressor units (also known as air pumps or air inflators) for electric vehicles serve as the air source for air braking, airbag operation, and air-pressure door opening and closing in electric buses, pure electric coaches, pure electric heavy trucks, and new energy logistics vehicles. They are a core component of pure electric vehicles. Currently, most new energy vehicles, such as pure electric heavy trucks, pure electric coaches, pure electric logistics vehicles, and pure electric sweepers, which use air braking systems, do not have engines and rely on air pressure braking and pneumatic door control systems. All of these require an electric air compressor to provide the air source.
The electric vehicle air compressor provides the air source for the vehicle's air pressure braking system and other auxiliary air systems. Its main purpose is to provide aerodynamics to the vehicle, primarily for braking, door opening and closing, air suspension, and airbag inflation. It is an essential key component of new energy vehicles, therefore requiring a high-quality electric air compressor.
