The Guardair N551BC 55‑gallon compressed‑air vacuum runs entirely on shop air — no motors or cords. Its venturi‑powered head generates up to 185″ water lift and 89 CFM suction, making it capable of picking up chips, dust, debris, most liquids or sludge. The kit includes a 55‑gal steel drum on dolly, 2″ × 20′ vacuum hose, metal wet/dry floor tool, crevice tool, 20′ air supply hose and standard cartridge filter — a durable work‑site solution for heavy cleanups.
