Oil Free Scroll Mini Electric Bus Vehicles Bus Cars Air Compressor

Oil free  scrollcompression is realized by rotational motion of static plate and moving plate.
The air is sucked in from the suction port at the outside of the fixed scroll. The air enclosed in the confined space is compressed towards the center when the compression chamber is becoming smaller due to the rotation movement. The compressed space becomes smallest at the center, and the air compressed to the highest limit is discharged out from the central exhaust port. The movement Figure 1-4 (Suction-Compression-Exhaust) is repeated thereby to produce compressed air without pulsation.
A reliable, high quality compressed air source is a significant part in the whole range of applications on vehicles, such as New Energy Vehicles, Electric Buses, Electric Vehicles, the EMU, Subway and Light Rail Vehicles. Adekom vehicle-mounted scroll oil-free air compressor, the ideal air supply equipment for various of vehicles and rail vehicles, including Pneumatic Brake Systems, Air suspension Systems, Door Operation, Pneumatic wiper systems, Pantograph lifting, etc.

Features of Portable Pump Cars Compressor
1,GUARANTEED 100% OIL FREE OPERATION -The scroll compressor requires no lubrication, so it does not have lubricating oil replace and reducing cost of unnecessary space parts that gas separator core, oil filters, which the contribute to inefficiencies as piston-type compressors do, it gives you the following benefits:
•  Reliability -Compressed air system without oil and hydrocarbon pollution, extending the valve and cylinder fittings and other parts service life; 
•  Maintenance-free-Completely solve the problem of lubricating oil emulsification for compressors, eliminating the issue of machine performance that aiming at the cause of lubricating oil temperature;
•  Economy-There is no risk of oil leakage, so It does not require a centralized processing and additional treatment for the condensate that benefit to environmental protection.
We are specialized in providing compressed air products and solution to our customers all over the world.
