Products advantage
1. Truly Oil-Free Compression, Clean Air Source: The scroll compressor chamber uses no lubricating oil during the compression process, resulting in oil-free output air. This avoids issues like sludge in pipelines and dryer failure, extending the lifespan of brake valves and dryer canisters, and meeting the stringent air source requirements of vehicle braking systems.
2. Smooth Operation, Low Noise and Vibration: The scroll motion is continuous and smooth, without piston reciprocating impact. The entire unit is equipped with rubber vibration damping supports, significantly reducing operating vibration and noise, improving the overall driving and riding environment, and making it suitable for urban buses and passenger vehicles.
3. Compact Structure, Integrated Module: Highly integrated design, with the motor, main unit, cooling system, and base all integrated into one unit. Its compact size and standardized installation interfaces facilitate installation by vehicle manufacturers, reducing the number of parts and simplifying assembly processes.
4. Durable and Reliable, Low Maintenance: Fewer moving parts and fewer wear points, eliminating consumable parts such as piston rings and valve plates; no need for regular compressor oil changes, daily maintenance only requires the intake air filter, significantly reducing vehicle maintenance costs and downtime.

A piston air compressor relies on the reciprocating motion of a piston within a cylinder to change the cylinder volume and complete the intake-compression-exhaust process. It is a very mature and traditional air source device, widely used in vehicles and industries.
Products FAQ
Q1: What is the core difference between an oil-free scroll air compressor and a traditional piston air compressor?
A: Scroll compressors rely on the meshing of moving and stationary scrolls for continuous rotational compression. The compression chamber is oil-free, outputting clean, oil-free compressed air; they have lower vibration and noise levels and fewer vulnerable parts. Piston compressors rely on the reciprocating compression of a piston; most models contain oil in the compressed air, leading to rapid wear of valve plates and piston rings, and frequent maintenance. Oil-free scroll compressors are preferred for the braking systems of new energy vehicles to avoid oil clogging of dryers and brake valves.
Q2: Is it truly completely oil-free?
A: No lubricating oil participates in compression within the chamber, ensuring the output air source meets the oil-free requirements for vehicle braking. Only a small amount of grease is present in the motor bearings, which will not enter the air circuit and will not contaminate downstream pneumatic pipelines.
Q3: What are the main routine maintenance requirements?
A: Low maintenance requirements: Regularly check/replace the intake filter (the most important consumable); Regularly blow away dust and debris from the radiator surface to ensure heat dissipation; Check the base shock-absorbing pads and pipe joints for leaks or looseness; No need to add or change compressor oil.
