A vacuum hose system with a pneumatic vacuum pump and floor sweep can be used to remove fugitive dust from around a duct collection/work area and draw it into the dust collector. Such an accessory provides an economical maintenance solution by adding a high-vacuum wand for clean-up to a low-vacuum dust collector.
The vacuum pump is powered by the same compressed air line that cleans the dust collector filters. The pump typically has venturi nozzles that create a high vacuum when the compressed air is applied. The dust is drawn into the inlet of the dust collector before the channel baffles so that large particles will not contact the filter media. A shut-off valve should be mounted in the vacuum hose to isolate it from the dust collector when not in operation. A second shut-off valve should be mounted to the vacuum pump to ensure that compressed air is only used when the system is in operation.
