A. Purpose and performance
PTFE coated oil-free and self-lubricating
piston with several patents for invention and utility model
has solved the problem of oil-free lubrication, eliminated
pollution, reduced friction coefficient, increased energy
conversion rate by more than 20%, increased air compression
strength by about 38%, and improved wear resistance at high
speed.
It is suitable for air compressor, new energy vehicle, intercity
transportation, high-speed rail, subway and other systems.
