The Mityvac MV7430 Pneumatic Venturi Vacuum Fluid Evacuator uses compressed air to create a powerful venturi vacuum for fast and efficient fluid extraction from small reservoirs. It features an integrated 1.9 quart reservoir that unthreads easily for emptying, along with an evacuation hose designed to reach tight areas. A variable control thumb throttle allows precise adjustment of vacuum strength, while the swivel air inlet improves hose positioning. The quiet, muffled exhaust enhances comfort during use, and automatic overflow prevention helps avoid spills. Compatible with 60 to 150 psi air systems and equipped with a 1/4 inch NPT inlet, the MV7430 is built for professional shop environments.
