Air-Cooled Electric Air Compressor
NFG03ZP
This oil-free scroll air compressor is specially developed for the braking air supply system of new energy buses, commercial vehicles, and special vehicles. It adopts the scroll compression principle to output clean oil-free compressed air, replacing the traditional oil-filled piston air compressor. It meets the air demand of new energy vehicles for braking, doors, suspension, etc. It has advantages such as high reliability, low noise, maintenance-free, and lightweight, and is suitable for pure electric and hybrid commercial vehicles.
Quantity:
Oil-free scroll air-cooled air compressors use air flow for cooling. Featuring compact design, light weight, low noise, and minimal maintenance, they are highly efficient and energy-saving. Ideal for compressed air supply in rail and new energy vehicles, including electric commercial vehicles, DMUs, subways, light rail, and other rolling stock.
