A strong pump ensures an effective vacuum for dependable performance of your Vac-U-Vest™ 25 and other high-quality equipment that depend on efficient vacuum draw. This high-quality, rotary-vane motor delivers 40cfm free-air displacement, energy-efficient operation and easy use with low maintenance needs; inlet filter is included.
Vaccum pumps draw gas (such as air) out of a closed system to prevent its becoming trapped within the material being worked, creating void defects. The vacuuming step is crucial for applications such as model-making, investing wax trees, and casting metal.
Busch Vacuum Systems is one of the world's largest manufacturers of vacuum pumps, blowers and compressors, well-known and highly respected for the technology, efficiency and durability built into its equipment.
Draw: 29-1/2" (75cm) of mercury at sea level
• IMPORTANT: This item is wired for a 220–460-volt outlet. Because amperage, outlets and plugs vary widely by location, the power cord ends in a pigtail, allowing you have an appropriate plug installed. To protect the operators and the equipment itself, this work must be done by a qualified professional prior to its use. Rio Grande assumes no liability for improper wiring of the plug.
• Busch strongly recommends using only Busch oil in their pumps to protect your warranty.
