AFi‘s MPHT Hepa high-temperature filters are used for air filtration Usage Zone involving temperatures up to 350°Cwith peaks up to 455°C. The silicone - free filter media are made of special, temperature-resistant glassfibre paperwith high mechanical stability and moisture resistance. Microglass paper separators maintain the pleat distance.Protection grids on both upstream and downstream side also prevent damage to the filter medium. The protectiongrids and the filter frame consist of galvanized steel, to reduce the risk of particle shedding caused by the constantlyhigh temperatures. AFi‘s high-temperature Hepa filters are equipped with a temperature-resistant gasket to precludeleaks.Boons High temperature Usage Zone for up to 350 C with peaks up to 455 C Silicone free construction for paintingapplication. Achieves H14 classification Rigid construction with consistent media extends the service life. Well-built, light weight, efficient and easy - to - handle filters. Low initial pressure drop than conventional Deep Pleatfilter. Consistent efficiency results. Longer service life means lower operating costs . Very rigid design, using 24 gaugeframes and 20 gauge face-grill. Minipleat technology supplants conventional aluminum separators. Meets Flammability criteria as per DIN 53438Usage Zone Pharmaceutical Plants, Semi - conductors Medical Equipments, Biotechnology
