Spectra Drop Shield Reverse pocket (SDSRP) filters are unique premium hydrophobic pre-filters in reverse air flow direction where space is a constraint. The SRP pocket filters serve as efficient pre or final filters in air intake systems of Gas turbines in any environmental condition (including offshore, marine) and in any climate (including tropical). They efficiently remove air borne particulate matter but also snow, mist and fog acting as a filter and a coalescer in one. SDSRP filters are specially designed for the elimination of free water and air borne salt crystals. Where subsequent final filters are placed, they protect them not only from coarse dust but also from running in wet conditions. The SDSRP filters do significantly prolong the filter lifetime of the final filter and increase their operational safety.
