If you are building a vacuum press for veneering, you'll find that the most critical component you will need is the vacuum pressure controller. The device measures vacuum pressure inside of a vacuum reservoir. It turns the vacuum pump on when the pressure inside the reservoir drops below a given level and turns the pump off when the correct amount of vacuum is reached.
* Adjustable from 1.5" to 28" of Hg.
* Differential: 2 to 5" of Hg.
* Contact Rating: 10 amps at 120VAC, 15 amps at 240VAC, 3 amps at 12VDC
Please note that there is only one model of this vacuum controller that we offer and it is rated for each of the voltages mentioned above.
If you are using a rotary vane vacuum pump, you must use a relay. Rotary vane pumps draw up to 3 times more amperage at startup than the name-plate shows. Most rotary vane pumps draw 6+ amps while running. This equals 18+ amps at startup which is too much for the vacuum controller to handle on its own.
Finally! Someone who knows what they're talking about! This vacuum controller runs my vacuum system that I use for veneering exotic woods to baltic birch plywood which is then scroll sawn and sold at conventions and home interior parties. Our vacuum press runs great thanks to the instructions on this website.
My friend and I built the vacuum press last night with a bunch of parts from this website. Everything went smooth and the press was ready to go this morning. We built a 2 foot by 4 foot bag and did a test run with the press. After a minute or two of adjustment, the vacuum was doing its thing just as we hoped it would. We are going to try vacuuming a veneer tomorrow! I cant wait to see how it turns out. So far..so good! Thank you.
