Meltblown fabric equipment need to use Roots fan?

Roots fan as a meltblown cloth equipment gas source equipment: mainly for the meltblown cloth production line to provide high-pressure airflow will be blown out of the molten state of polypropylene, where the need for air volume and pressure stability of the gas source equipment, if the pressure with a Roots fan is generally 98Kpa can be used, generally 70-80Kpa will be enough to use, there is no need to pursue the excessive pressure, the different production lines need to be equipped with a different output of the fan air volume.

Practice has proved that the Roots fan is the most economical and stable meltblown gas source equipment. Air compressor pressure is too high, the second is the work process requires oil lubrication, even if the claimed "oil-free" air compressor, but only in the internal oil and gas separator, there will still be a small amount of oil mist with the airflow out, resulting in meltblown cloth odor, made into a mask odor is obvious, resulting in the test does not meet the standards. From the situation of 250 production lines matched by Jinkong to customers, more and more production lines are using Roots blowers instead of air compressors.
