Abstract
The present invention is a device that rapidly and effectively separates and collects debris from airflow between a debris source and a vacuum source. The device comprises a first chamber situated above and adjoining a second chamber. The first chamber functions to separate and remove the debris and the second chamber functions to collect the debris. The first chamber is circular in cross-section and comprises an upper portion and a downward and outward sloping sidewall. The upper portion has an output port connected by a first conduit to the vacuum source and the sidewall has an input port connected by a second conduit to the debris source. Air and debris are drawn into the first chamber through the input port by suction created at the output port. The debris is centrifugally forced to the sidewall whereby it is then centripetally forced downward into the second chamber through a peripheral opening between the sidewall and a barrier, while cleaned air is evacuated through the output port.
