Hot Gas Filtration With Proven Performance Across Your Industrial Applications<\/h1>\n \n

Purefrax\u00ae filter elements are vacuum formed using Alkegen\u2019s own refractory ceramic fibers, and are manufactured from Alkaline Earth Silicate (low bio-persistent\/AES) or Alumino Silicate wool (ASW). \u200b<\/p>\n

Our unique binding system provides low levels of organic binder, enabling Purefrax\u00ae filters to retain strength and integrity when exposed to heat. \u200b<\/p>\n

With our trusted manufacturing process, we ensure dimensional accuracy and a denser outer surface, promoting cake filtration and uniform dust deposition in addition to extra strengthening of the flange and candle base areas.<\/p>\n

Introducing Purefrax dP, a new product offering with reduced pressure drop. Engineered for energy efficiency, our new formulation demonstrates 64% pressure drop and 6x fewer cleans compared to our standard hot gas filters, providing you with an estimated >10% operational cost savings. With higher air flow for less capital cost, Purefrax dP is the superior choice for energy efficiency.<\/p>\n<\/div>\n \n Email Us To Learn More<\/a>\n <\/div>\n

    Introducing Our Catalyzed Hot Gas Filters, a Combination of Alkegen\u2019s Long Established Hot Gas Filter Expertise With Expert Catalysis Knowledge\u200b<\/h1>\n \n

    In addition to providing high efficiency particulate filtration, Purefrax\u00ae CC filter elements incorporate a custom-designed catalytic formulation for NOx<\/sub> reduction. \u200b<\/p>\n

    Uniting particulate capture with toxic gas removal creates a single-step process with reduced required space, all while lowering your capital and operating costs.<\/p>\n

    Independent testing shows almost 100% NOx<\/sub> conversion and <5ppm ammonia slip across a wide range of applications.\n<\/p>\n<\/div>\n \n <\/div>\n
