CARRYING UNIT FOR BLOWER ASSEMBLY

摘要

A carrying unit for a source of pressurized air having a frame and at least one wheel on the frame through which the frame can be supported upon and moved over a subjacent support surface. A conduit assembly is part of a pressurized air handling system on the frame and has an inlet for receiving pressurized air from a source and first and second spaced outlets for discharging pressurized air directed through the inlet. The pressurized air handling system further has an air control system that is changeable selectively into different states. By reason of changing states, the air control system causes at least one of: a) a different volume of air from the inlet to be directed to the first and second outlets; and b) a change in a direction of air discharging from one of the outlets.

主权项

1. A carrying unit for a source of pressurized air, the carrying unit comprising:
a frame; at least one wheel on the frame through which the frame can be supported upon and moved over a subjacent support surface; and a pressurized air handling system comprising a conduit assembly on the frame and having an inlet for receiving pressurized air from a source and first and second spaced outlets for discharging pressurized air directed through the inlet, the pressurized air handling system further comprising an air control system, the air control system changeable selectively into different states, the air control system configured so that by reason of changing states the air control system causes at least one of: a) a different volume of air from the inlet to be directed to the first and second outlets; and b) a change in a direction of air discharging from one of the outlets.
