More Benefits Than Being Adjustable

Published on by Brian Farno2 Comments

Years ago I was working with a pet food manufacturer who was having issues with their bag opening machine. The problem they had with their existing setup was the dust from manufacturing processes would get sucked into the venturi and start to decrease their performance. Hence, they needed a better solution that wouldn’t need to be replaced and could be cleaned.

Adjustable E-Vac

The bags were empty, and this vacuum generator was positioned to pull the bag open. The bags were made of a non-porous material as they had a coating on them and thus the actual action of opening the bag was not difficult. Enter dust through the throat of a small venturi, and it caused several downtimes that were not scheduled. When looking at the performance characteristics of their existing system I crossed that over to an EXAIR model 840008M – Adjustable E-Vac w/ Straight Through Muffler. This unit was able to open the bag and hold it open for their machine needs. The throat passage of the unit was also larger than their existing generator and the biggest benefit, the Adjustable E-Vac could easily be taken apart and cleaned. To see how easy they are adjusted, which is the same method used to take them apart, check out this previous video blog linked in the image below.

The process changed from changing an existing vacuum generator out, scrapping the old one, and putting in a new one to keeping two on hand. One (EXAIR Adjustable E-vac) that is in operation and functioning, then after a designated amount of time (predictive maintenance), they change it out for the spare (EXAIR Adjustable E-vac) vacuum generator. The second part of the process involves breaking the used one down (without the need for any specialized tools), to clean each of the three pieces on the unit. The refurbished unit is then reassembled, benchmarked for performance, and put on the shelf for the next maintenance cycle.

While this system uses the same volume of compressed air as their previous solution, we still save money in the amount of unusable replacements they were ordering with repairable units, allowing them to keep a working spare on hand. So it saves the customer money on the life of the product. A further benefit is the customer can also get the EXAIR Adjustable E-Vacs quickly as they are standard stock item for us at EXAIR and can ship the same day on orders received by 2 PM ET.

Published on by Tyler DanielLeave a comment

In order to make sure you’re able to get the most out of your Intelligent Compressed Air Products from EXAIR, we offer a wide variety of various hoses and tubing to complement several of our product lines.

For any Line Vac Pneumatic Conveyor application, you may need appropriate tubing to handle the intake and outlet flow of the conveyor. EXAIR offers a clear reinforced PVC hose from stock in sizes ranging from 3/8” to 3” ID for use with our smooth Aluminum, Stainless Steel, and Heavy Duty Line Vacs. The PVC hose is available in lengths up to 50’ in 10’ increments and is on the shelf ready to ship, alongside the Line Vacs themselves. The hose is very flexible with a smooth internal bore that eliminates material build up. The reinforced, heavy wall of the clear hose provides visual confirmation that the material is moving when compressed air is supplied to the Line Vac. These hoses are rated for use in temperatures ranging from -4 to 150°F (-20 to 66°C).

 To help supply air to your Safety Air Guns, we offer (3) different styles of 12’ (3.6m) coiled hoses to help keep the area free of tangled air lines. Sizes are available in 1/8 NPT x ¼” ID, ¼ NPT x 3/8” ID, and 3/8 NPT x 3/8” ID. Each coiled hose has swivel fittings installed on either end for ease of installation.

If you need a bit longer length to supply your point-of-use products, or need a larger diameter hose, we also have both 3/8” and ½” ID compressed air hoses. These are manufactured with a reinforced synthetic rubber to assure long life and protection against ozone, weathering, and temperatures up to 158°F (70°C). Hose lengths are available in 10’, 15’, 20’, 30’, 40’, and 50’.

For EXAIR’s E-Vac Vacuum Generators, polyurethane vacuum tubing (along with various push-in fittings) is available to help connect to the necessary vacuum cups. The tubing comes in either ¼” ID or 3/8” ID in lengths ranging from 10’ to 50’. This allows you to build up a complete vacuum system when including the mufflers, vacuum cups, and generator itself!

All of these options are available from stock to ship alongside any Intelligent Compressed Air Product. If you need help determining the proper hose sizes based on your point-of-use products get in contact with an Application Engineer today for help!

EXAIR E-Vac Vacuum Generator Accessories: Overview

Published on by codybiehleLeave a comment

Vacuum systems are becoming more and more prevalent within manufacturing day by day. Vacuum powered lifts can make it easy to lift and move small objects like tiny coins to heavy steel plates. Vacuum chucks hold work pieces that could be marred by jaws or vises. And sealed vessels can be pressure tested or tested for leaks by pulling a vacuum on them. It’s pretty simple to pick out which vacuum generator that you need, but what about the accessories? There are so many different accessories to choose from such as mufflers, suction cups, hose, valves, and connections. The following is a quick overview of the different accessories that you can get from EXAIR along with your E-Vac vacuum generator.

Vacuum cups for E-Vac generators

Suction cups are a very common accessory that you need when using a vacuum system. Vacuum cups allow one to create a seal on the surface of the object that you wish to pick up and is what allows the system to lift objects. We offer four different kinds of vacuum cups to choose from stock; available are small and large Round, Oval, and Bellow styles. Round cups are more suited to being used on smooth, flat surfaces. Oval cups provide the most vacuum due to the larger surface area making them ideal for lifting heavy loads. The Bellows style is best suited for textured or uneven surfaces; the folds provide a collapsible area that allows the cup to compress and seal on an uneven surface.

EXAIR’s Standard and Straight Through Muffler

Next up is the mufflers; they muffle the sound generated by the E-Vac and quiet a working vacuum generator. There are two different types of mufflers from EXAIR that are available; these are the Standard and the straight through mufflers. The Standard muffler is designed to be attached to the discharge end of an in-line E-Vac and has a closed end. These are best suited for applications that are free from dust and debris. The straight through muffler is open all the way through and are more suited to applications were dirt, dust and debris is present. The straight through style also offers the best sound level reduction, up to 26 dBA.

Lastly the E-Vacs have an NPT threaded connection that will allow for a suitable connector to be properly installed. From here different connectors can be used to attach the various amounts of vacuum cups. The connectors provided are Push-In Connector Type Fittings of assorted styles available with our polyurethane tubing to make the installation and plumbing a cinch.

When it comes to our E-Vac vacuum generators and creating a successful design for you application EXAIR has the fundamentals. EXAIR’s compressed air powered E-Vacs are designed primarily for pick and place operations but also have other uses such as evacuating liquids and gasses from containers and holding workpieces in place. E-Vacs come in different sizes including an Adjustable E-Vac in order to dial in your vacuum and vacuum flow. EXAIR E-Vac generators are engineered for high efficiency and minimizing air consumption.

In-Line E-Vac Generators are compact and easily mount at the point of use. They can held in place by screwing them directly to your rigid compressed air line or by using one of our mounting clips. There are 7 models used with porous materials, such as carboard, with vacuum levels up to 21″ Hg and vacuum flows up to 18.5 SCFM. There are also 7 models to choose from for non-porous materials, such as glass, with vacuum levels up to 27″Hg and vacuum flow up to 15.8 SCFM.

Adjustable E-Vacs (below) allow easy adjustment, simply loosen the locknut and turn the exhaust to increase or decrease the vacuum flow. There are 4 sizes with vacuum up to 25″Hg and vacuum flow up to 81 SCFM. They are Engineered for high efficiency and minimize compressed air usage by adjusting the vacuum level to the application.

EXAIR has four cup styles to match and accommodate just about any size shape and material. Let’s look at the cups available and their characteristics:

Round Cups come in small and large sizes and work well with smooth flat surfaces . The round cups hold up well with time and grip well to vertical surfaces. Round cups without cleats are more flexible and work well in applications that do not require lifting heavy loads. Round cups with cleats

Oval Cups provide the most vacuum due to having a larger surface area. Shape matters: this is especially true for oval cups which have a higher suction power compared to round cups. The are designed to handle heavy objects such as flat rigid sheet materials.

Bellow Cups have an accordion shape and designed for textured, uneven surfaces. The folds are called convolutions and provide a collapsible area allowing the cup to compress when it touches an uneven surface.

Once you have selected the style and quantity of vacuum cups you can review the EXAIR Accessories that will compliment your project. EXAIR offers a variety of mufflers, tubing, check valves, fittings that will make it easier to build your vacuum system.
