Abstract: The invention relates to air treatment equipment for the removal of impurities from the air such as odorous substances and bacterial spores. The equipment includes a support member made of silicon carbide, preferably beta silicon carbide, which gives it good thermal conductivity and allows it to operate as an electrical heating element. The support member has air passages through which air to be purified passes, the walls of the air passages being coated with a catalyst material such as platinum. In a preferred embodiment the support member also contains silicon oxynitride which imparts a better mechanical stability to the supporting element and allows the conductivity to be reduced.

Abstract: The invention relates to air-treatment equipment for removing impurities from the air, particularly substances having an odor or taste and bacterial spores. The equipment includes a heating element, maintained at a high temperature, over which the air passes or is directed and this causes air borne particles to break down into odorless substances. The equipment includes a heat exchanger arrangement which serves to reduce the temperature of the heated air returned to the room or space from which the air was withdrawn. The heating element of the heating unit is made of electrically conducting silicon carbide having a thin coating of catalyst material.
