These single stage, cylindrical units are compact and easy to mount at the point of use. Kits include vacuum cups, vacuum fittings and vacuum tube.They can be held in place by threading them directly onto a compressed air line or with the use of a mounting clip. High vacuum units up to 27" Hg (91 kPa) with vacuum flows up to 15.8 SCFM (447 SLPM) are typically used for non-porous materials such as glass, steel sheet and plastic. The Standard Muffler has a closed end and is suitable for applications that are free of dust and debris. The Straight Through Muffler is recommended where particulates are present since it will not accumulate debris that can erode performance. Straight Through Mufflers offer the best sound level reduction (up to 26 dBA).

Accessories

Accessories Needed To Build Your Vacuum System

EXAIR offers a variety of mufflers, tubing, check valves, and fittings that make it easy to build a vacuum system best suited to your vacuum application. In addition to these E-Vac vacuum generator accessories, there are other items that can help with the preparation and control of the compressed air.

When using E-Vac vacuum generators, it is important to use a source of clean, dry compressed air that will keep them operating at their peak performance. Automatic drain filter separators to keep the compressed air free of contaminants and moisture are recommended. Oil removal filters that remove oil particulate that is common to many compressed air systems are available. Pressure regulators, shutoff valves, compressed air hose, fittings, and solenoid valves (to electrically turn the compressed air on and off) are available as well.

Mufflers

Optional silencing mufflers are available that permit maximum exhaust of the E-Vac unit so cycle speed is not reduced. The Standard Muffler (for use with In-Line E-Vacs only) has a closed end and is suitable for applications that are free of dust and debris. The Straight Through Muffler is recommended where particulate is present since it will not accumulate debris that can erode performance. Straight Through Mufflers offer the best sound level reduction (up to 26 dBA).

Fittings and Tubing

The vacuum port of the E-Vac has an NPT thread (a vacuum cup can be threaded directly into it). For vacuum cups that are remotely located, push-in connector fittings (most have global threads for use with NPT and BSP) can be installed on the E-Vac and the vacuum cup. Polyurethane vacuum tubing is available (10', 20', 30', 40' and 50' lengths) to connect them. For best performance, the length of the tubing should be minimized to achieve the best attach and release times.

Check Valve

A vacuum check valve is available to hold the vacuum in case of compressed air loss. It is designed for high flow so it doesn’t restrict airflow or slow the vacuum operation. Maximum vacuum can still be achieved without affecting the performance. E-Vac vacuum generators that are used without a check valve will release the load if there is a significant drop in compressed air pressure or the supply of compressed air is lost.

Two Styles – Low Vacuum and High Vacuum

EXAIR manufacturers two styles of E-Vac – High Vacuum and Low Vacuum. The application will dictate which type of vacuum is most suitable.


Low vacuum units up to 21" Hg (71 kPa) are typically used for porous materials such as cardboard, and delicate materials. The low level vacuum prevents any warping, marring, dimpling or disfiguring of the surface due to excessive vacuum. This style generates more vacuum flow to overcome porosity and leakage.


High vacuum units up to 27" Hg (91 kPa) are typically used for non-porous materials such as glass, steel sheet, and plastic.

How The In-Line E-Vac Works

How the In-Line E-Vac Works

Compressed air flows through the inlet (1), then through a single directed nozzle (2). As the airstream exhausts, it expands and increases in velocity prior to passing through the venturi (3). A vacuum inlet tangential to the primary airflow (4) is located at the suction point between the orifice and the venturi. The airflow that is drawn through the vacuum inlet mixes with the primary airstream, then exhausts on the opposite end (5).

In-Line E-Vac Standards and Certifications

How to Build An E-Vac System

1.Select the E-Vac type.
 A.Determine if the part to be lifted is porous or non-porous.
 B.Select a style - In-Line Low Vacuum, In-Line High Vacuum or Adjustable. The E-Vac type determines max. vacuum available for lifting the part and vacuum cup selection.
Porouslow vacuum generators max. vacuum = 21" Hg (71 kPa)
Non-poroushigh vacuum generators max. vacuum = 27" Hg (91 kPa)
Adjustable E-Vacvacuum generators max. vacuum = 25" Hg (85 kPa)
2.Determine the weight of the part.
3.Multiply the weight by the vacuum cup safety factor for the total vacuum cup capacity needed.
4.Determine the number of vacuum cups needed by considering the following:
 A.How many cups are needed to distribute the weight for stable lifting and placement?
 B.What is the weight that each vacuum cup can lift based on maximum vacuum available (E-Vac type)?
 C.Select vacuum cups based on max. vacuum available (E-Vac type) and holding weight/cup.
5.To choose an E-Vac model number, consider the entire vacuum system from the E-Vac to the part.
 A.Number of vacuum cups per E-Vac
 B.Length and size of vacuum tubing
 C.Vacuum cup size and type
  • The volume of air to evacuate from your vacuum system and the vacuum flow of the E-Vac you've selected will determine the time it takes from E-Vac activation to vacuum cup holding the part. As the vacuum level in the system increases, the volume of evacuating air decreases.
  • A lower volume of air in the vacuum system and/or a higher capacity (SCFM/SLPM) E-Vac will give faster pick-up times.
  • An exact pick-up time cannot be calculated.
  • If the E-Vac vacuum generator doesn’t meet your needs, return it for a different model, with no restocking charge.

Here is an example using the steps outlined above:
A sheet of material measures 3' x 3' (.91m x .91m) and weighs 25 lbs (11.3kg). Each sheet is in a stack and will be placed on a conveyor.

If it is porous like wood and positioned vertically:

1.Choose a porous, low vacuum E-Vac. In this case the In-Line style will be used. The maximum vacuum is 21" Hg (71 kPa).
2.The weight is 25 lbs (11.3kg).
3.Since the part is picked-up and hung on an overhead conveyor vertically, the safety factor is 4. The vacuum cup capacity needed is 4 x 25 = 100 lbs (45.4kg).
4.Four vacuum cups will be used for stability when lifting the sheet. Each cup will need at least a 25 lb (11.3kg) capacity. The Model 900755 Vacuum Cup will hold up to 25.3 lbs (11.5kg) at 21" Hg (71kPa).
5.There are 4 small round vacuum cups that are positioned close to one another. The vacuum system has a small to medium volume and pick-up and release time is not critical. To reduce the sound level, use the straight through muffler.
Order:(1) Model 800008M In-Line E-Vac; (4) Model 900755 Vacuum Cups

If it is non-porous like glass and positioned horizontally:

1.Choose a non-porous, high vacuum E-Vac. In this case the In-Line style will be used. The maximum vacuum is 27" Hg (91 kPa).
2.The weight is 25 lbs (11.3kg).
3.Since the part is picked-up and placed on a belt conveyor horizontally, the safety factor is 2. The vacuum cup capacity needed is 2 x 25 = 50 lbs (22.7kg).
4.Four vacuum cups will be used for stability when lifting the sheet. Each cup will need at least a 12.5 lb (5.7kg) capacity. The Model 900754 Vacuum Cup will hold up to 20.8 lbs (9.4kg) at 27" Hg (91 kPa).
5.There are 4 small round vacuum cups that are positioned close to one another. The vacuum system has a small to medium volume and pick-up and release time is not critical. To reduce the sound level, use the straight through muffler.
Order:(1) Model 810006M In-Line E-Vac; (4) Model 900754 Vacuum Cups

NOTE:
The Model 840008M Adjustable E-Vac can be substituted for picking up the wood or the glass since the vacuum level and vacuum flow is easily adjusted to suit the porous or non-porous application. The Adjustable E-Vac is especially useful for loads that vary.

Increased Energy and Vacuum Efficiency

Energy and vacuum efficiency are not limited to the Adjustable E-Vac vacuum generators. All E-Vac styles and models can offer significant improvements when looking to reduce the amount of compressed air used for a specific vacuum application. Once the appropriate amount of vacuum and flow for the application are determined, it is important to select the appropriate model that will deliver the best performance while using the least amount of compressed air that it takes to do the job.

Many companies have a centralized vacuum system where the vacuum is generated at a location that is far away from the point of use. The long runs of piping through the plant produce line loss and it is often difficult to obtain that perfect balance of vacuum and flow required for an application. The compact In-line E-Vac vacuum generators eliminate this problem since they can be mounted at the point where the vacuum source is needed. EXAIR’s Application Engineers can help you to select the E-Vac vacuum generator and vacuum cups that provide the right amount of lifting capability while minimizing the amount of compressed air usage.

Other Applications for the E-Vac

E-Vacs are used in many other “non-lifting” applications. They are commonly used for vessel evacuation, clamping, chucking, and other work holding applications. Many types of automated equipment use vacuum to evacuate, grip, hold, align and insert parts. These vacuums can be used for surface mounting, vacuum packaging, bag opening, label placement, carton forming and container evacuation.

Another popular application is using the E-Vac for liquid sampling. This process can easily be accomplished using an E-Vac vacuum generator attached to a liquid holding tube. When the tube is dipped into the vat, tank or container, the compressed air is turned on so it draws a specific volume of liquid up into the tube. When the compressed air is turned off , the liquid flows from the tube and can be dispensed into a container or machine to be analyzed.

Choosing An E-Vac

 

E-Vac® Vacuum Generators Are Easy To Use

The construction of the E-Vac is aluminum. The vacuum inlet can be easily connected to existing tubing, piping and hose. Durable vinyl vacuum cups for pick and place applications are available. Optional silencing mufflers are available that permit maximum exhaust of the E-Vac unit so cycle speed is not reduced.

Choosing The Appropriate E-Vac Vacuum Generator

EXAIR’s E-Vac is available in 2 styles that include the In-Line E-Vac and Adjustable E-Vac. Each design has been engineered for use in a variety of applications. These single stage, all aluminum units provide consistent, steady vacuum, unlike mechanical vacuum pumps. Dust and small particulates easily pass through the vacuum generator and they have no moving parts, making them maintenance free.

In-Line E-Vac Vacuum Generator

In-Line E-Vac

This series of single stage, cylindrical vacuum generators are compact and easy to mount at the point of use. The In-Line E-Vac can be held in place by threading them directly onto a compressed air line or with use of a mounting clip. Each In-Line vacuum model has a specific level of vacuum and flow. This style can easily pass dust or small particulates. There are 7 models suitable for use when lifting porous materials (like cardboard). The “porous” models have vacuum levels up to 21"Hg (71kPa) with vacuum flows up to 18.5 SCFM (524 SLPM). There are 7 models for use with non-porous materials (like glass) that have vacuum levels up to 27" Hg (91 kPa) with vacuum flows up to 15.8 SCFM (447 SLPM).

Adjustable E-Vac Vacuum Generator

Adjustable E-Vac

This series of Adjustable E-Vac single stage vacuum generators permit easy adjustment by simply loosening the locknut and turning the exhaust to increase or decrease the level of vacuum and vacuum flow. These are ideal for use with porous and non-porous materials where the load can vary. Vacuum flow is easily increased when the vacuum is being used on a porous surface. This style passes dust and larger size particulates so there is no loss in vacuum, making it the best choice when working with dirty, dusty materials (such as concrete mix, plaster, etc.) There are 4 models with adjustable vacuum up to 25"Hg (85kPa) and vacuum flow up to 81 SCFM (2,294 SLPM).
