There are many things that can cause your Speed Vap III to have a problem with the vacuum. Such as the following examples:
1. The compressed air has to flow through the Speed Vap, if there is no exhaust, there is no vacuum. (The exhaust contains solvent vapors and should be properly vented)
2. There may not be sufficient compressed air being delivered to the Speed Vap. (2 CFM is required)
3. If the unit is connected to a Solvent Trap, the rubber stopper that goes into the collection flask may not be making a good seal.
4. The seal on Speed Vap III lid compresses over time and it will need to be replaced to maintain a good seal.

termed a Vapor Lock can occur.
