Variable Vacuum Pumps
$94.61 – $320.10
Variable vacuum pumps allow the user to adjust the venturi performance to generate the vacuum flow and vacuum level needed for the application. These venturis have an inline flow path (suction and exhaust are in-line) meaning they are extremely dirt tolerant as dirt and debris will pass straight through the pump. Combine a straight through silencer for quiet operation with no impact on performance.
These venturis achieve a maximum vacuum level of 85% vacuum.
Ideal for material handling applications of very dusty product such as construction materials including drywall, wood, concrete blocks, bricks, corrugated, paper, etc.
