Multi-faceted hollow ball in the middle along the entire perimeter of a reinforcement ring, ring up and down each twelve ball valve. Upper and lower ball valve with each other, along the central axis was radial layout. I plant in the production of engineering plastics unit help sum up the experience, confirmed that the product has the following advantages: Due to the large surface area; the departments of high mass transfer efficiency, product space is large, and light weight, high strength, easy installation, welcome widely used. Features: high gas velocity, leaves and more resistance; large specific surface area, can be fully resolved fluid exchange; has a small resistance operating flexibility characteristics. Such fillers used for water treatment works. Main Uses: Widely used in addition to chlorine, in addition to oxygen, in addition to carbon dioxide gas and other environmental equipment.
