Conventional flue > CAT Enabled flueless




The catalytic process uses a proven, specially formulated ceramic filter or Catalyser to ‘scrub clean’ the burnt gas emissions produced by the cooker’s burner. As a result it does not need a flue to vent them outside.

This proven catalytic gas technology not only neutralises these emissions, it really does clean the air in your kitchen creating a healthier kitchen environment. The Catalyser is extremely durable and comes with a guaranteed long life performance.
