RoboVent launched the new Delta3 inline spark arrestor. Built from heavy-gauge steel with an all-welded construction, the spark arrestor allowed zero sparks through ductwork at all tested airspeeds and tied for the lowest pressure drop among all tested technologies. The spark arrestor can be used with a variety of dust collectors on the market, including RoboVent’s new Senturion dust collector. It can be placed at the inlet of the dust collector (or other types of equipment) or inline with ductwork for dust collection, ventilation or the HVAC system.
