Equipment: Automatic sand equipments are supplied with hydraulic counterwash valves, joints, screws, suction pads, pressure gauges, an automatic cleaning timer, a differential pressure switch, a safety filter and connection collectors. Security filters: A safety filter with a manual/automatic screen or disc cartridge can be installed after sand filters to improve filtration. Materials: Filter body and collectors made of carbon steel with a treatment of sandblasting- phosphating, inner/outer electrostatic paint coats in epoxi-polyester, later polymerized in a high-temperature oven. They can be manufactured from stainless or galvanized steel. Modularity: Its modular design allows an easy enlargement and adaptation to any kind of spaces. Regarding these equipments, the number of filters, the diameter of collectors and the size and number of valves depend on flow, water quality and filtration grade required. Pressure features: Maximum work pressure: 10 kg/cm2. Equipments with higher pressure requirements can be also supplied to order.
