The woodsaver blower will help make any standard wood fired arch more efficient. The blower runs on 110 volts and has a variable speed control. It comes with the blower, duct work, and the rheostat control. A hole is cut in the tin so the air is blowing in under the grates, and the duct work just bolts to the arch. This model is a 1/15hp blower that runs on 1.28 amps, and is 463 cfm. This blower works on a 3'x12' up to a 4'x10'. This is not a stock item, but it is a special order.
