Topsoe’s catalytic filter bags - CataFlex™ - gives any facility the option of treating off-gases along with trapping dust. Each CataFlex™ filter bag consists of layers of fabric, one lined with a PTFE membrane and each layer featuring its own unique catalytic formula, enabling a single bag to remove dust and multiple gaseous compounds in one step – eliminating the need for costly, space-demanding tail-end gas removal equipment.

TopFrax™ is the industry’s state of the art high-temperature-resistant emissions filter. Made from refractory ceramics and impregnated with carefully selected catalytic compounds, the candle-shaped TopFrax™ treats industrial high-temperature off gases up to 400 degrees celsius. The catalytic ceramic filter trapping dust while removing NOx, CO, VOCs and dioxins in one single process.
