<p>PURPOSE:To remove the CO and NO2 exhausted into room and permit comfortable heating by mounting a filter which removes harmful gases such as CO and NO2 at ordinary temp. to a heater with a fan. CONSTITUTION:A harmful gas removing filter 1 is installed to the air suction port of a warm wind blow-out fan 2. The warm wind by the exhaust gas burned in a burner 3 warms the room inside, after which it passes through the filter 1 and is again blown out into the room. The filter 1 consists in installing simultaneously or alone the CO oxide catalysts prepared by carrying noble metals on the kneaded molding of a NO2 removing agent prepared from the kneaded molding of alkali, cement material and powder active carbon, cement material and powder active carbon. As a result, the removal of the CO and NO2 in the room is made possible and the prevention of the air pollution in the room by the fan heater is achieved nearly perfectly.</p> |
