Module for the maintenance of SF6 gas-filled equipment Treatment of contaminated SF6 gas Special Features 3-in-1 filter insert for filtering out particles, reactive decomposition products and humidity Easily replaceable filter insert High gas flow rate through flow optimisation Robust and reliable sealing construction Corrosion protection through anodised filter case Description Efficient protection from contaminants As research has shown, decomposition products such as HF, SO2, SF4 and SOF4 can form in gas-insulated equipment with discharges or failures. The model GPF-10 SF6 filter unit ensures reliable treatment of contaminated SF6 gas. The particles found in decomposed SF6 gas, such as aluminiumfluoride (AlF3) or copper fluoride (CuF2) are effectively retained by the integrated particle filter, so that the operator does not come into contact with these substances. The filter unit is installed to protect the service equipment (e.g. transfer unit or suction pump) from particles, humidity and decomposition products. Following filtration, in the best case, the SF6 gas can be reused. Replaceable filter cartridge The filter cartridge can be replaced easily and within a few minutes. Thus the service equipment is operational again and fully effective within the shortest of time. Optimised design With the design of the filter unit, a premium was placed on a high gas flow rate and a robust construction. The anodised aluminium case makes the GPF-10 suitable for outdoor use and resistant against corrosion. The case reseals securely after a filter change and prevents any emission of environmentally harmful SF6 gas.
