The PETRO-BARRIER™ PTB-DF-24 is a prefilter placed at the top of the PETRO-BARRIER™ POMPE to trap impurities present in filtered water from the retention tanks and pits of large transformers. This system minimizes the risk of clogging and helps keep the system running smoothly. Description The PETRO-BARRIER™ PTB-DF-24 is a prefilter that fits onto cartridges in the SPI® PETRO BARRIER™ POMPE range. Invented by SPI® in the 1990s, it completes the filtration system of PETRO-BARRIER filters, which are easily adapted 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 period of use (see Additional Information tab). Placed at the top of the PETRO-BARRIER™ POMPE PTB-24 in the inlet chamber, it serves as the first water-cleaning prefilter before the PTB-SF-24 and 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 caused by large particles and impurities in the water (stones, leaves, twigs, etc.). PETRO-BARRIER™ PTB-DF-24 description: Composed of several sets of filtering grids and foams, with different mesh thicknesses to block impurities in the water.
