Product Description


One of the most critical components you will need for the vacuum system is the vacuum switch. For the sake of clarity, our kits refer to this item is as a vacuum "controller". It's the device that measures vacuum inside of the reservoir and controls the electric power to the vacuum source. It turns the vacuum source on when the vacuum inside the tank drops below a given level and turns the vacuum source off when the correct amount of vacuum is reached.

If this item is being used to replace the vacuum controller found in the Project: V4 Premium vacuum press kit, please contact us prior to ordering.

WE OFFER NO WARRANTY ON THIS PRODUCT - - - SOLD AS-IS!
This is due to the number of people who have bought this vacuum controller (separate from a kit) and have tried to create "Frankenstein" vacuum press systems that destroyed the vacuum controller. These people ruined it for everyone else by demanding free replacements.

DO NOT PURCHASE THIS PRODUCT UNLESS YOU CAN SHOW THAT IT IS GOING INTO A PROJECT: EVS™, PROJECT: V2™ or PROJECT: V4™ VACUUM PRESS SYSTEM
Do the right thing instead and purchase a vacuum press kit which allows the vacuum source to reliably, properly and safely release the back-pressure from the pump when it cycles off. The kit is designed to protect the vacuum controller and prevent the pump from stalling and over-heating.

NOT FOR USE WITH ROTARY VANE PUMPS
Rotary vane pumps draw too much amperage at startup and that will fry the vacuum controller. Even with a relay, we do not offer any support for vacuum press systems that use a rotary vane vacuum pump.

240V INSTALLATIONS ARE UNSUPPORTED
Due to the liabilities of high voltage, we do not offer any support for 240v AC. We can not provide assistance, instructions or diagrams for building a high voltage system. Please a certified electrician before purchasing and/or building a 240v system.




What is the difference between the Type 1 and Type 2 vacuum controller?
The most important difference is the range of adjustment. The type 1 unit is what comes with the V2 and EVS vacuum press kits. It allows a high level of vacuum to be applied before shutoff. The Type 2 vacuum controller is better suited to model builders who need less vacuum for their projects and a smaller differential range.

Who would use the Type 2 version?
Model aircraft builders typically want a lower vacuum setting.

Which version of the vacuum controller comes with the vacuum press kits?
The Type 1 is the vacuum controller that is included in the kits.

Will a rotary vane vacuum pump work with the vacuumcontroller?
No. Rotary vane vacuum pumps such as the Gast 1023 and 0523 vacuum pumps have been a nightmare for me. I have found them difficult to fine tune for vacuum pressing and they draw a tremendous amount of power when they start up. There are much better choices in vacuum pumps than rotary vane. I am well aware that several other companies are using rotary vane pumps for their vacuum press systems.

If you are using a rotary vane pump, you will at least need the relay and vacuum damper parts. I offer ZERO support for troubleshooting vacuum press systems built with rotary vane pumps. If you try to use the vacuumcontroller with a rotary vane pump, please know that I will not be able to help you troubleshoot problems. You waive your right to return this part if you are using it with a rotary vane pump.


Product Reviews

  1. Great Price - Works Well

    Review by Joey Lebow

    I'm using a vacuum pump to vacuum bag fiberglass composite parts. The pump was too strong and sucked too much epoxy from the parts. This controller allows me to set a desired vacuum level, and it automatically turns the pump on and off to maintain the desired pressure. Added bonus: the pump isn't running continuously anymore.


  2. Nice Part

    Review by Bill Simpson

    Nice part, compact, easily set, holds pressure nicely, has small hysteresis, and does not appear to stick in either position. Good piece.


  3. Great Site, Great Service

    Review by C Christensen

    Have not used it yet. This is more for the order and the site. With shipping, the vacuum switch was less expensive here than from a company that specializes in pneumatics. Even if I would have found it for less, I hope I would have still bought it here, in support of this great source of information. The part shipped next day and I had it within 3 days. Very satisfied.


  4. Highly Recommended

    Very good product, with a good price. Fast a friendly service. They let me know as soon as the unit shipped and had FedEx keep me up to date on when it would arrive.


  5. Using This for 15 Years

    Simple and reliable, this controller works great. Allows me to dial in the 18-22 inches pressure that works for me. This place is a really important source for veneering work!

    Bought the whole system form Joe except the pump which I already owned. Takes some time but easy to assemble. Works great. Thanks for the thorough instructions.


  7. Review from Middleton, Wisconsin

    This is so nice. I build fiberglass composite vacuum bagged wings for my RC sailplanes. Before adding this switch, I had to babysit my the vacuum on my projects for several hours while the epoxy cured. Now I can go to bed! The directions were simple to follow and the system worked the first time I threw the switch. I also got the relay, and maybe didn't needed it -- but for $20 it's good security.


  8. Reliable but watch the amps!

    Review by Frank Gilmore Jr.

    If you've got a big pump, get the relay. I burnt up my controller quickly because I didnt heed the advice shown on this website. The owner of the site helped me figure out my stupidity and I ordered a new one with a relay. There have been no problems since then. Take it from me, it doesnt pay to overlook the details.


  9. Works Like A Dream

    I followed the instructions and built my own press using this device as the controller. It installs easily and works like a dream.


  10. Our Vacuum Press Runs Great

    Review by Bonnie Watts

    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.

    Great item. Works perfectly and was easy to mount and adjust.


  12. Everything Went Smooth

    Review by Carrol Feinman

    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.
