- Use the Venturi Vacuum Generator to deflate Inflatables faster when the pipeline pressure is not sufficient to force air out.
- The Venturi requires more air to deflate the inflatable than was used to inflate.
- A large volume of air will leave the exhaust port.
NOTE: Personnel should never be in direct line of the exhaust port.
