Roots blower is the most economical and stable melt jet source equipment

Practice has proved that Roots blower is the most economical and stable melt jet source equipment. First, the pressure of the air compressor is too high, and the second is that the oil lubrication is required during the working process. Even if the air compressor is called "oil-free", there is still a small amount of oil mist or water vapor. Along with the air flow, it causes "shot" and odor in the melt-blown cloth, which reduces the filtration efficiency, and the odor is obvious when it is made into a mask, and various tests fail to meet the standards.
