Is the Roots blower of the melt-blown cloth production line or the air compressor better?

Air compressor or Roots blower is the air source equipment for high-pressure hot air flow, but the air compressor relies on the piston to compress the air in the closed cavity to output the air flow, and the piston and the casing must be lubricated with lubricating oil, or It will overheat and burn, and then filter the oil after the gas comes out, but it can only filter most of the oil mist, or a small amount of oil mist will be ejected with the air, forming a melt-blown cloth with the molten polymer, think with your feet I can imagine that there must be an oil mist smell on this meltblown cloth. In addition, the pressure of the air compressor is above 100KPA-10000KPA. This pressure is too high for the melt-blown cloth, which is not conducive to the formation of cohesive force of the melt-blown cloth.
