E-Vac Generators, Cups and Accessories

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.

Are EXAIR’s Hoses and Tubes Right For You?

Are you tired of ducking and dodging hard pipe everywhere? Do you need something more mobile for your compressed air? Then EXAIR Hoses and Tubes might be a solution for you. EXAIR offers a variety of hoses and tubes in different styles designed to work with our products without affecting performance. These products simplify the use, setup, and integration of our various products into your process. Normally if you were to buy hoses you would need to determine the proper diameters, pressure ratings, and/or end fittings to best fit the item in use. This is all unnecessary when purchasing EXAIR’s Hoses and tubes for EXAIR products since everything is sized and properly rated to be used with our products. So, ask our Application Engineers if EXAIR Hoses and Tubes are right for you.

 Products may include the following.

Line Vac air operated conveyor hose
Conveying Hoses:

These hoses are used with our Air Operated Conveyors or Line Vacs which are used to convey material from point A to point B. The hose can be mounted on either side of the Line Vac using the properly sized hose clamp that comes with it. The Conveyance hose is made out of a durable PVC semi-flexible material in sizes from ¾” I.D. to 3” I.D. to match our Line Vac sizes. They also come in lengths up to 50’ in increments of 10’.

Coiled hose
Coiled Hoses:

When it comes to getting compressed air to our safety air guns, we offer a series of abrasion-resistant nylon Coiled Hoses. The coiled hose comes in a 12’ long length and comes in 3 sizes; these sizes are 1/8” NPT, ¼” NPT, and 3/8” NPT to attach right to EXAIR’s Safety Air Guns. The hoses also include swivel fittings to make for easier uncoiling. The coiled design makes it easy to reach around the work area and retract back to the substation. With the right size hose Coiled Hoses can supply the required amount of compressed air with minimal amount of pressure drop.

Compressed air hose
Compressed Air Hoses:

Compressed Air Hose can be used to reach equipment from overhead or near equipment. These hoses are made with synthetic rubber and comes in 3/8” I.D. and ½” I.D… Lengths up to 50’ long can be provided and the hoses are rated for up to 250 psig air pressure. These hoses can provide lasting protection from ozone, weathering and temperatures up to 158oF. They also come with two male ends in ¼” NPT or ½” NPT.

Stay Set Hoses
Stay Set Hoses:

Bendable and flexible, the stay set hose allows for manual positioning of your compressed air product. Equipped with “memory” function, the hose will not creep or droop until it is physically moved. The Stay Set Hose comes in lengths from 6” to 36” in length, and they offered in a combination of 1/8” and ¼” MNPT connections. These hoses are rated for 250 psig and are made of a reinforced rubber.

EXAIR Hoses and Tubes are Great Accessories

EXAIR offers different styles of hoses and tubes as accessories to our product lines.  They are built and designed to easily fit with our products as well as being sized correctly to not affect performance.  It simplifies the use, setup, and integration of EXAIR products in your facility.   You do not have to determine the proper diameters, pressure ratings, or end fittings to best fit the EXAIR products to maximize their performance.  Also, having these items available from one source minimizes the number of purchases and vendors necessary for a complete and working solution. In this article, I will go over the different hoses and tubes that EXAIR can provide.

Conveying Hoses:

The hoses above are used with our Air Operated Conveyors or Line Vacs.  The Line Vacs are designed to move product from point A to point B.  If the Line Vac is the “vehicle”, the Conveyance Hose is the track.  The hoses are made of a durable PVC semi-flexible hose with 6 different diameters from ¾” I.D. to 3” I.D.  The conveyance hose can slip easily onto the EXAIR non-threaded style of Line Vacs.  EXAIR can cut-to-length Conveying Hoses up to 50 feet (15m); in increments of 10 feet (3m).

Coiled Hoses:

To get compressed air from the piping system to the Safety Air Guns, we offer a series of Coiled Hoses.  They are made of a durable abrasion-resistant nylon material that is 12 feet long (3.6 meters).  They have swivel fittings to allow for easy uncoiling, and a spring strain relief to keep the hose from kinking.  The coiled design makes it easy to reach around the work area and retract back to the substation.  This will help to keep the hose off the ground where potential dangers could occur.  We offer 3 different connection sizes of 1/8” NPT, ¼” NPT, and 3/8” NPT to attach right to the Safety Air Guns.  With the proper size, the Coiled Hoses can supply the required amount of compressed air with a minimal amount of pressure drop.

Compressed Air Hoses:

If you need a compressed air line to reach from overhead or around equipment, the EXAIR Compressed Air Hoses would work with these applications.  They are made from a reinforced synthetic rubber in 3/8” I.D. and 1/2” I.D. diameters.  We can make specific lengths up to 50 feet (15m).  They are rated for 250 PSIG (17 bar) air pressure, and the hose material works well for long lasting protection against ozone, weathering and temperatures up to 158oF (70oC).  They come with two male ends in ¼” NPT or ½” NPT.

Stay Set Hoses:

The Stay Set Hose gives you that possibility of manually adjusting or re-adjusting Super Air Nozzles.  The hose has a “memory” function, and it will not creep or droop until you physically move it.  They work well to direct air flows in specific target areas.  They can be used with Super Air Nozzles, Safety Air Guns and Blow-off Kits.  The Stay Set Hoses come in lengths from 6” (15cm) to 36” (91cm), and they are offered with ¼” NPT male on both ends or with a 1/8” NPT female and a ¼” NPT male connections.  These hoses are rated for 250 PSIG (17 bar) and are made from reinforced synthetic rubber.  If positioning is required for accurate blowing or re positioning for different areas, the Stay Set Hose would be a nice addition to your equipment.

Vacuum Tubing:

For our E-Vac product line, EXAIR offers vacuum hoses to connect the E-Vac vacuum generators to the suction cups.  They are made from polyurethane in ¼” O.D. and 3/8” O.D.  The tubing is very flexible for moving product, and they can resist the vacuum pressures created by the E-Vac.  They slip easily into our Push-In Connectors to quickly attach vacuum cups to the E-Vac system.  EXAIR can sell both types of tubing up to 50 feet (15m) in increments of 10 feet (3m).

Hoses and tubes may seem like simple things, but EXAIR already did all the research in determining the best material and correct size for optimum performance.  You can leverage this information to save you time and money when using EXAIR products in your application.  If you need help in selecting the correct model, you can contact an Application Engineer.  We will be happy to help you.
