Oil-free Piston Electric Bus Air Brake Compressor

Short Description:

The principle of an oil-free air compressor: With each rotation of the compressor crankshaft, the piston reciprocates once, and the cylinder successively completes the processes of intake, compression, and exhaust, thus completing one working cycle.

Product Description

We provide advanced electric air brake compressors for commercial vehicles—including plug-in hybrids, standard hybrids, and pure electric vehicles—covering a diverse range of vehicle types such as trucks, buses, and vans. Our electric bus air brake compressors feature a two-stage, oil-free design that ensures the output of clean, oil-free, and moisture-free compressed air, thereby completely eliminating concerns related to oil emulsification, leakage, and fire hazards. Thanks to an innovative structural design, the compressor minimizes energy loss during the compression process, resulting in a significant improvement in overall operational efficiency.

Furthermore, our air brake compressors demonstrate exceptional environmental adaptability, operating stably and reliably across a wide temperature range spanning from as low as -40°C to as high as +65°C. This high level of reliability ensures that the equipment maintains uninterrupted, superior performance, even under the most demanding environmental conditions.

Our air brake compressor systems have successfully entered mass production and commercial application, with some units having already surpassed a cumulative operating mileage of 300,000 kilometers. This system is now widely adopted by numerous renowned domestic and international Original Equipment Manufacturers (OEMs), including Foton, BYD, SANY, JMC, and JAC. The applicable vehicle models span a diverse range of drive configurations, specifically encompassing tractor units, construction vehicles, light-duty trucks, municipal vehicles, logistics vehicles, and urban passenger buses.
