Http://www.kqnglq.com/ shallow spherical shell filter media and a unique interior design can ensure a smooth flow of water filtration, filter effects, the formation of numerous internal circulation backwash, recoil efficiency. More traditional sand filters, with automatic filter, automatic backwash sand, less cost of water and so on. Features unique 48 "AGF spherical shallow media filter unit, has many advantages .AGF automatic control filtration system uses a modular design, based on the size of the flow, can be used to select multiple filtration units of time, pressure and other means automatically start backwash, the system sequentially each backwash filter unit, the other unit is still in the filter, high efficiency recoil recoil short time, when the backwash water conservation (water consumption is about 30% recoil traditional sand filters) easy to install, without any lifting device. Light weight of the system, no special foundations, general concrete floor can be. Applications typically feed water circulating cooling water, swimming pool, landscape seawater circulating water filtration water filtration filter unit 48 inches Structure and advantages: allows unfiltered water distribution even in case of high water flow can also uniform flow through the packing layer and maintained on a flat surface of a superficial layer of the packing media filter has two large openings, for the top observation and feeding, bottom for emptying and maintenance. Each port is a completely leak-proof design, the system applies the principles of hydraulic closed, safe and reliable. Unique 55 mushroom-shaped pressure compensating filter catchment, the system in the filter Each part of the hydrostatic equilibrium state, the filtration velocity, high efficiency; in the backwash state, formed in circulation, high efficiency and does not run sand recoil spherical shell, can fully meet water distribution uniformity of water distribution with the 55. Mushrooms mouth, forming a backwash within circulation, efficient backwash, do not run the sand. shallow outer filter media made of composite material, with a high ballast ratio and corrosion resistance. integrally molded spherical shell can withstand 0.59Mpa opening shallow medium pressure from black polyethylene, resistant to environmental pressures, to prevent embrittlement and is not invasive chemicals. pressure compensated catchment, near the middle of the small opening, near the end of a large inner filter This is consistent to the respective catchment outlet pressure * For larger flow filtration units can be connected together more piping materials: carbon steel spray polyester, or PP plastic; valve materials: steel, or PVC plastic pipe interface: standard DIN connector size in accordance with the actual requirements of more detailed information, please contact us.
