The PETRO-BARRIER™ PTB-SF-24 is a prefilter placed at the top of the PETRO-BARRIER™ PUMP to trap fine particles present in filtered water from the retention tanks and pits of large transformers. This system reduces the risk of clogging and helps to keep transformers running smoothly. Description The PETRO-BARRIER™ PTB-SF-24 is a prefilter that fits all cartridges in the SPI® PETRO BARRIER™ POMPE range. Invented by SPI® in the 1990s, it completes the filtration system of PETRO-BARRIER filters, which adapt easily to all types of retention tanks and pits. It helps to ensure continuous filtration of drainage water, while trapping harmful hydrocarbons. It prevents soil pollution in compliance with EN 858-1 and the French Water Act, with a discharge rate of less than 5ppm. It also complies with paragraph 471 of NF C13-200 (“All precautions must be taken to ensure that the recovery tank does not fill with water or that water is evacuated“). Our filters and pre-filters are regularly tested in independent laboratories, when new, in half-life conditions and after their recommended service life (see Additional Information tab). Placed at the top of the PETRO-BARRIER™ PUMP PTB-24 in the inlet chamber, after the PTB-DF-24 prefilter, it enables finer cleaning of the water before coming into contact with the active material in the PTB-C-24 filter cartridge. The pre-filter is essential to limit the risk of filter cartridge clogging due to fine particles and impurities in the water (dust). Description of the PETRO-BARRIER™ PTB-SF-24: Composed of several sets of grids and foam filters, with different mesh thicknesses to block impurities in the water.
