RoboVent DownFlow vs. Competitors

The biggest loss of filter life in any dust collector is due to “re-entrainment.” Re-entrainment is the term used for picking up dust that has already been removed from the filter and redepositing it on the filter. In fact, experts believe that filter life could often be extended almost indefinitely if re-entrainment could be totally eliminated. With DownFlow, the air is brought in evenly and without turbulence from the top.

The general movement of air within the cabinet is downward, the same direction as the falling dust that has been removed by the pulsing system. This makes the equipment especially difficult to build, but the increased filter life makes it well worth it.

Note: The current design of the RoboVent Plaser System including the DownFlow and vertical cartridge filter concept is patented.
