Armstrong BVSW Series Inverted Bucket Drain Traps are designed for systems where heavy oil and dirt may be encountered. The enlarged bucket vent equipped with a scrub wire (BVSW) allows free flow through the bucket vent and discharge through the orifice in the top of the trap. Connections are screwed, flanged, PN40 or PN100.
