The RSHT chimney fan is a high-temperature exhaust fan used to maintain proper draft in a solid-fuel chimney or stack system. It is the preferred fan for venting fireplaces, barbecues, pizza ovens, and stoves that produce extreme heating conditions. The RSHT chimney will sustain continuous temperatures of up to 1,000 degrees, and it allows use with short chimney stacks due to its grade 316 stainless-steel design and internal cooling vane.
