| Summary: | This invention relates generally to ventilation, or air exhaust, systems and concerns more specifically such systems that are easy to install, use and control at separate targeted stations of work sites and buildings.
A vacuum air exhaust system () employs a venturi vacuum pump () that is fed pressurized air through a control valve unit () rigidly mounted on a vacuum pump housing () of the vacuum air exhaust system. By manipulating a movable valve of the control valve unit, an operator can control a vacuum applied by the vacuum pump. The vacuum air exhaust system is rigidly attached to a pipe-type mount unit () for being rigidly attached to a wall at a hole in the wall so that ventilation suction is applied through the pipe and the wall. In one embodiment the exhaust adapter is attached to a flexible hose () and in another embodiment it is rigidly screwed to a pipe (), such as a filter pipe. |
