The 334 4 blade heat powered stove fan is one of the most popular designs we offer. Not only is it small, but it is extremely powerful. At only 187mm high and 180mm wide, the 334 can fit into most stove surrounds. Also, because of its small design, it sits lower to the stove, has great circulation and therefore blows out very warm air. Should you need smaller in height, then out 524 or T84 coming in at just 125mm tall would be the perfect fit.
