Corrosion-resistant material, high-precision filtering ink impurities, more effective protection of the nozzle, to extend the life of the nozzle.Cost-effective, safe, using environmental protection materials, strict control of production links.Upgrade negative pressure design, ink can flow out smoothly, print clear constantly ink

Inside the ink bag is a filter screen, mainly used to filter impurities brought about by ink, reduce the probability of nozzle plug, if long time not replaced, ink bag will greatly increase the probability of nozzle failure
