This is quickly changing, however, based on the numbers you saw above. Generally, vacuum generators run on electricity in a majority of modern installations. Best of all, this kind of configuration could theoretically save power over a comparable electrical installation. In other cases, you can even power actuators that are designed to run with vacuum power instead of the positive pressure that most people are used to working with when they install a pneumatic system. By generating vacuum suction in this way, you could move many different types of materials. The check valve combination makes them even easier to interface with. On top of this, they offer mounting hardpoints from three sides as well as a supply and release valve combination. ZL series devices offer a special compact design that doesn’t take up anywhere near as much space as most other competing devices. In a majority of situations, it can also represent a fairly dramatic savings in terms of space. Other features of this 1.2mm nozzle device include a built-in suction filter, an exhaust silencer and high-quality one-touch tube fittings.Īs you might imagine, this represents a massive savings in power over older technologies. Technicians can opt to find them in versions with an onboard vacuum switch as well as a digital readout. For each 1 scfm of compressed air this particular model of vacuum ejector consumes, it generates 1.587 scfm of suction flow. This is compared to around 40 percent for most other similar devices. In some cases, the force of this can be quite dramatic and noticeable.Ī multiple-stage design, like the ZL series, can operate at approximately 150 percent efficiency. This flow, however, can power a device that in turn will actually reverse the direction and provide a level of suction. Usually, when you think of pneumatic pressure you think of a positive flow. These days, it’s used in almost every type of pneumatic workflow that you can possibly think of. At one point, this technology was used to power vacuum cleaners. Perhaps more importantly, technicians have recycled the term pneumatic ejector to refer to another technology that allows people to generate a vacuum using relatively simple equipment. Others have turned to them as a method of moving fluid and powder from one location to another. These are sometimes used for removing byproducts from automated manufacturing workflows. This allows it to serve many different capacities as far as waste removal is concerned.Īs you might imagine, technicians have come up with more uses for this kind of equipment besides cleaning up sewage and other types of waste. That allowed the tank to eject the material it contained by using the positive airflow. This tank was designed for collecting sewage.Īs soon as it reached a predetermined level a sturdy valve would force pressurized air into the tank.

In this particular case, technicians used the term pneumatic ejector to refer to simple mechanisms connected to a holding tank. Consider, for instance, the fact that the definition of what a pneumatic ejector is has changed over time.Īt one point, compressed air-driven ejectors normally referred to a certain type of device that was primarily used in the plumbing industry. In the meantime, you might want to bone up a little more on how certain components work so you can share a few pointers with everyone in your organization. Anytime you don’t recognize a pneumatic part, you can take a look at our convenient database for more information. In any of these situations, it can stop you right in your tracks and even be a little embarrassing,Īs far as compressed air-driven equipment goes, SMC Pneumatics has you covered. Have you ever been looking through a catalog or schematic and found that you don’t recognize a pneumatic part? The same problem happens to those who are trying to connect electrical equipment and even hydraulic gear.
