1.0 OVERVIEW
The Laurell Technologies’ IV - pneumatic vacuum generator is capable of generating a
variable amount of vacuum depending on input air pressure. It creates a vacuum by
venturi action.

INSTALLATION
1.
For best performance use a dedicated CDA or N2 supply regulator for the
vacuum generator. The generator’s flow rate is approximately 1.67cfm at
60psi. See figure 2.
Note:
It may be possible to “tee” the CDA or N2 supply to both the processor
and the IVPVG but there must be a sufficient volume of gas to satisfy both. If
there is an insufficient volume, the processor will produce a “Need CDA” error
message. Also, there may be a loss of vacuum from its initial level (when the
vacuum is first applied).
