Minneapolis DuctBlaster® Round Transition Piece
This Minneapolis DuctBlaster® component connects to either the fan exhaust flange (pressurization testing), or the inlet flange (depressurization testing). The Minneapolis DuctBlaster® fan and round transition piece are connected using a 40 inch piece of connecting trim (item DBTRIM sold separately). The pieces of flexible tubing and tubing connectors attached to the round transition piece, are also used during depressurization testing. The round transition piece and flexible duct are connected by inserting the center ring of the transition piece inside the duct and tightening a zip tie strap around both of them.
