An oil-lubricated air compressor draws air into a storage tank with a screw that requires oil to keep the production process running smoothly with maximum efficiency. The oil injected in the compression chamber keeps the system cool by dissipating the heat and acting as a lubricant to lower the friction between the moving parts. Oil-lubricated screw air compressors are efficient, reliable, quieter, and last longer. Their ability to work quietly makes them effective for various pneumatic tools and accessories.
