Vacuum Testing of Aerospace Equipment implementing Custom Chambers
A large aerospace company and a DoD contractor requested a quote from us for a custom vacuum tester to be utilized for the vacuum testing of various Aerospace Equipment Parts on their production line. All of their items were solid and ridged containers, cubic, square, and cylindrical which needed to be tested by following the vacuum submersion testing technique.

With that said, this test does require an extra step in that the part must be under vacuum when it is above the water level. As soon as the target vacuum is reached, the part is dunked under water. Once the test is completed, the part is lifted above the water level one more time before the chamber is vented. The solution we provided was to modify our standard Vacuum Bubble Leak Tester to accommodate all our client’s requests. The vacuum chamber is about 12-inch Wide, 10-inch Deep, and about 8-inch High. The vacuum is generated by a standard duty, rotary vane vacuum pump. The rotary vane vacuum pump comes with an oil mist eliminator, exhaust filter that will minimize or prevent from oil mist being exhausted into it’s surroundings. Furthermore, the rotary vane vacuum pump also comes with a vacuum pump protection valve which will close off if water is present in the vacuum line.

The chamber is top loading with a hinged lid. On the lid is the vacuum gauge, the venting valve, and the vacuum valve. Inside the chamber is a plate that can be lifted either upwards or downwards, depending if the testing sample is needed to be above the water line or below the water level. The specimen plate is lifted via the two levers which are connected to the front wall. A vacuum rotary feedthrough will translate rotary power from the outside of the chamber to the inside of the chamber without compromising vacuum during operations. The levers can either swing inwards and lower the tray or swing outwards and lift the tray. We also have a fully automated pneumatic version that does not use levers by four pneumatic cylinders to drive the tray upwards or downwards. If you are looking for a vacuum dunk test which requires some complex procedures, feel free to reach out to us to discover how we can assist you with you leak testing needs.

Acrylic Vacuum Chambers
Acrylic Vacuum Chambers are, as the name implies, vacuum chambers made from the Acrylic Polymer. There are several advantages to acrylic vacuum chambers the three main ones being 1. Fully Transparent, 2. Cost Effective, and 3. Versatile and Highly Customizable.
Altitude Simulation Controller Instruments
An Altitude simulation Controller is type of vacuum controller that simulates a certain altitude because altitude can be derived from vacuum levels. An altitude simulation controller will enable you to hold your vacuum level at a certain altitude equivalent of testing, run an altitude vs time profile, or rate of change of altitude vs. time. Further options include a vacuum pump relay that will control when the vacuum pump turns on and a vacuum valve.
Our Work: Leak Quality Testing and Quality Control of Packets
Quality Control during Production runs is a very important procedure you must perform on your manufactured products. This is especially critical is you are an FDA manufacturer where regulatory compliance is important and necessary. Our Vacuum Chambers are specifically built to assist you meet your Quality Control and Regulatory compliance needs.

Bubble Leak Testing or Bubble Emission Testing is a procedure where leaks are visually detected and located through the emission of bubbles while the test specimen is submerged in water. In this article, we will talk about using an acrylic vacuum box as a leak detection device. We are also going to talk about the advantage, disadvantage, and the bubble leak emission test procedures.
