Vacuum Ejectors: Benefits and Drawbacks

We have talked a lot about the working of the vacuum ejectors and their configurations. We have also compared them with other vacuum generators. In this article, we will have a look at all the major advantages of having or using vacuum ejectors. Once we are done with the benefits, we will shed some light on the drawbacks of these items as well. After all, nothing is perfect in this world and these vacuum generators, despite their tons of advantages, have a handful of drawbacks that you should look out for as well.

Vacuum Ejectors: Advantages

Here is a salient list of features that vacuum generators have to offer to their users.

Inexpensive: The first thing to consider is their low cost. Since the design of vacuum creators is really simple, they aren’t really that expensive especially when you compare them to other vacuum generators.

Quick: This is one of the most underestimated benefit of vacuum ejectors. Since they don’t require any kind of warm up and they don’t have any delay, they are very quick. You can turn on or turn off the vacuum within seconds

No resource consumption: These vacuum pumps, literally, do not require any resources. They don’t require electricity or any other type of fuel to work. Simply input the air and you will be good to go. In the long run, this will save you more than just a few bucks.

Quick installation: These do not demand a lot of time during installation. Simply insert them and connect their input to an appropriate outlet. The same thing can be said during replacement as well. Installation and changeover of these is a one man job that takes a minute.

Zero moving parts: This is another advantage of vacuum ejectors that is overlooked a lot. Having no moving parts doesn’t seem a lot but it has a lot of benefits. The first and biggest benefit is that it doesn’t create ant vibrations. Usually, moving parts cause a lot of vibration which is bad for the whole system especially if there are sensitive equipment near the vacuum generator. Second thing worth noting is that most of the problems comes from the moving parts i.e. they get jammed or get broken or friction etc. None of this will happen if you there aren’t any mechanical parts.

No heat: Heat is another very big problem when it comes to systems. These vacuum pumps generate no heat at all. This is because they don’t require any kind of fuel nor do they have any moving parts. It is a simple static design that take air as an input and creates the vacuum. So, no heat generation.


High tolerance: Since the design of these vacuum generators is really simple and they don’t have any moving parts, they have a very high tolerance. There is just a static solid design and that’s it. So, there aren’t many things that can have an effect on their operating.

Of course, this is just the tip of the iceberg. There are a lot more benefits that cannot be discussed here.

Vacuum Ejectors: Drawbacks

Here are some of the disadvantages.

Technical knowledge: In order to use these products or at least know the specifications required for your system needs a bit of technical knowledge. And, if you want to use these as efficiently as possible, you will need to have a decent amount of technical knowledge.

Learning curve: Again, this is somewhat relate to having the technical knowledge to get the best out of your vacuum pump. Although it is true that these products can be very efficient and can reduce a lot of your costs but only if they are used correctly. If you don’t know what you are doing then using a vacuum ejector won’t help you reduce the costs. Proper system design, vacuum requirements, cycle’s time and lot of other information is needed to get the best out of this equipment.

Time consumption: Although vacuum generators saves a lot of time during installation or replacement, they will gobble up a lot of your time in learning and knowing the exact numbers or measurements. The learning curve can be quite time consuming.


The conclusion here is that vacuum ejectors are very efficient and provides a ton of benefits for their users but all of that comes at a cost. You need proper knowledge of not just how these work but you also need to know about your system and all its requirements in order to get the best out of these type pf vacuum generators.
