Abstract
The thermal insulation blower of the present invention is built around a vertically oriented air lock system. The insulation blower is capable of being configured for high delivery rates suitable for open area blowing and is capable of being reconfigured for lower delivery rates as a through-the-blower system for closed area blowing operations. The insulation blower includes a metering feeder assembly which can be adjusted to control the rate at which a bale of insulation is ripped and fed into the air lock system. The thermal insulation blower of the present invention also includes a bypass system around the air lock which serves to automatically clear impending plugs of insulation material in the delivery hose.
