Purefrax® Hot Gas Filter Candles

The Unifrax Purefrax® Hot Gas Filter Candles are designed to remove particulate matter with filtration efficiencies exceeding 99%. Purefrax® Hot Gas Filter elements were developed and commercialised in 1996, originally for the aluminium industry to solve an issue of fires happening within the baghouse filter. Sparks were being carried over in the gas stream and setting fire to the fabric filters. Purefrax filters were developed using our high-temperature fibres and are designed to work in the same way as a traditional fabric filter but with much higher temperature capability and insensitivity to sparks. Since 1996, the benefits of the product mean that they have been used in a variety of applications from incineration, to product recovery to power generation (such as Waste-to-energy).

Key features of both the Purefrax hot gas filters include:

  • A high temperature use limit
  • Compatibility with sorbents
  • Non-combustibility
  • Corrosion resistance

Designing pollution control equipment around Purefrax hot gas filtration media saves CAPEX and OPEX and reduces the footprint of the installation while providing extended service life and energy savings.
