If I were getting started and looking to buy a vacuum pump there are a couple things that I would look for.
- 3 Gallons or larger
- Tall instead of wide
- Top vented instead of side vented
The reason I think that 3 Gallons is the minimum size for a vacuum chamber is that you can fit 4-6 cups of silicone in there easily. That should be enough to cover just about any pours you might want to do.
I would also recommend that you don’t get one that is too tall or too wide. If your vent is too close to the silicone you run the risk of pulling silicone splatter up into your vacuum gauge, hose or – even worse – your vacuum pump. So I like to keep the vent as far away as I possibly can without compromising on how many cups of silicone I can get in there. (The BVV chamber listed below is a nice compromise).
And the 3rd recommendation is a corollary to the second – having the vent in the lid or at the top of the chamber makes it harder to draw silicone into your gauge/hose/vacuum pump chain. Which means that you are less likely to damage your gauge, hose or vacuum pump!
