Abstract
A machine for distributing loosefill insulation from sources of compressed loosefill insulation is provided. The machine includes a shredding chamber having an outlet end and a plurality of shredders configured to condition the loosefill insulation. The plurality of shredders is configured to operate at variable rotational speeds. A discharge mechanism is mounted at the outlet end of the shredding chamber. The discharge mechanism is configured for distributing the conditioned loosefill insulation into an airstream provided by a blower. The blower is configured to operate at variable rotational speeds. The plurality of shredders, the discharge mechanism and the blower are configured to operate on a single 15 ampere, 110 volt a.c. power supply. The variable rotational speeds of the plurality of shredders are configured to provide variable flow rates of the loosefill insulation and the variable rotational speeds of the blower are configured to provide variable flow rates of the airstream.
