External filter vacuums
External filter vacuums are powered by compressed air, and are ideal for heavy-duty industrial wet/dry applications such as recovery of metal shavings, sawdust, machine oil, sand and water that require strong suction power. They feature a large collection tank, sometimes with a tip-and-pour function, on front swivel castors for easy transport and stability. An external collection bag and filter allow the recovery of wet and dry material without stopping for a filter change.
A hose attaches to the tank for wet/dry collection of debris. The air compressor system maintains a lower psi at the gauge for light debris and a higher setting up to 100 pounds per square inch for maximum suction.
