Vertical Stacks and Transitions

Exhaust stacks are supplied in either galvanized steel, coated steel or stainless steel to match the blower construction. Connections are either slip fit (stack and blower are steel or coated steel construction) or flanged (stainless steel construction). Inlet and outlet transitions are available for most popular duct sizes. Specify slip fit or flanged connection.
