Re: Venturi Pump legality

Please note the picture uses water as the medium, but our devices would have used the pressurized air.

According to the manual R66 , any device which creates a vacuum would not be subject to the pneumatic rules. However, a Venturi pump would utilize the pneumatic system components.

Would such a system have been legal last year? Thoughts!
Venturi valves are interesting when it comes to the rules - half of the valve is considered pneumatics, while the other half isn't. So as others have mentioned, you would have to run the valve off of a legal pneumatic system, which (probably) couldn't generate enough airflow to create sufficient vacuum to pick up a tote. My team tried them way back in Rack N' Roll, and couldn't quite get it to pick up an inner tube!

When teams want to use a vacuum, most often they'll take something like a shop vacuum apart and replace the internal motor with a legal one. It can create a LOT more suction for you that a venturi valve can with our pneumatics limitations!
