Pneumatic industrial drum vacuums operate on a compressed-air supply to suction dust and dirt or liquid spills into their drum for disposal. They withstand high-frequency use and reduce the risk of downtime since they have no electric motor to burn out. These air-powered vacuums are commonly connected to air compressors at construction sites or pneumatic hoses in manufacturing facilities.,Industrial shop vacuums provide greater suction than general purpose or commercial-cleaning shop vacuums to pick up heavier particles and liquids. Their 2-stage or 3-stage motor allows high-frequency use for heavy-duty cleanups of dust and dirt or liquid spills. They're commonly used at manufacturing facilities and building or construction sites.Specifications:Sound Level:78 dBTank Material:Stainless SteelTank Size:18 galVacuum Collection Type:BaglessVacuum Hose Dia.:1 1/2 inVacuum Hose Length:15 ftMinimum Air Compressor:15 hpAir Inlet:1/2 in Quick ConnectInlet Connection Gender:FemaleInlet Connection Type:Quick ConnectItem:Drum Vacuum
