Where To Find The Best Vacuum Feedthrough For You


The vacuum feedthrough is a marvel of modern engineering that is typically used to connect vacuum pumps, tubing, and chambers to one another. It happens to be just one of many different types of flanges currently on the market that you have to choose from. Other options include: KF/QF, ISO, CF, wheelers, ASA, and gaskets.

The way that a vacuum feedthrough works is technical, but not too difficult to understand. Basically, it contains a vacuum tight connection, either electrically, physically, or mechanically, to the chamber. An electric model allows the electricity produced to be fed into components under the vacuum, such as the filament and heater. A physical type will typically use a connection that is vacuum tight to keep water cool. And the mechanical type both rotates and translates a medium that is under vacuum.

If you are looking for a good company that sells these products online and always has a good supply in stock, you may want to turn to Ferrotec. Their vacuum feedthrough uses ferrofluid, a magnet, two poles, and a magnetic permeable shaft to create a basic seal. Whenever fluid is applied to the radial gap located under each pole piece, it forms the shape of an O ring and a hermetic seal is produced.

The following is just a short list of the many benefits that are offered by their products:

• Hermetic sealing – provides a seal against gas, vapor, and contaminants with low rates of leakage.

• Long Life – Because these units operate with no friction between the rotating electrical components and the ones that do not move, the seal experiences no wear and tear.

• Highly Reliable – Simple design makes for the possibility of very few parts that are subject to wear.

• Non-Contaminating – The lack of mechanical friction between the fluid and the seal means that no small particles are created that could lead to the contamination of your system.

• High Speed Capable – Even at high speeds of rotation the hermetic seal can be maintained. One inch of vacuum feedthrough equals a speed of rotation of roughly 20,000 rotations per minute.

As you can see, there are a lot of advantages to choosing the Ferrotec brand vacuum feedthrough. However, this does not mean that you do not have other options. The Internet has several sites that you can visit and browse through their feedthroughs, gaskets, and other flanges. In fact, this is a good idea because you do not want to make a purchase from the first web site that you visit. Take a look at a few different distributors for these products and see what they all have in stock. You may even be able to find a company in your area that deals in them so you don’t have to pay shipping.
