Utility boilers, Cement, Carbon and Steel manufacturing units widely use woven glass media, which is suitable to sustain for continuous temperatures of (260°C) along with the capacity to take care of short duration of surge temperatures. To fulfill the demands of high temperature filtration and in case of poor performance of conventional needle felts like PPS and P-84 during higher oxygen and moisture levels in the gas stream, we craft exclusive woven fiber glass filter bags of different weight, construction and efficiency. Since, the glass acts as a heat sink, these perfectly carved bags can take care of hot particles without creating holes and easily withstand for excess oxygen percentage in flue gases in a boiler application. These bags hold the ability to undergo most rigorous chemical environments and thus prove great value for money.
