Hi,posted this on the general composites...thought it might suit better here.

Hi
Id like to know what are the main differences between using a venturi vacuum system and a pump sistem.
Purchasing a venturi one seems cheaper(already have a good compresor),but Id like to know what is the downside if there is,and its limits.
We are focusing on small bycicle parts,no infusion.
Thanks in advance.

A Venturi will not produce the required vacuum, and is impractical to use for the hours needed

and they can be quite noisy
