In-Line E-Vac® Vacuum Generators

Vacuums for lifting, clamping, mounting and placement!

The In-Line E-Vac (porous version) is used to lift the plywood lid of a crate in a receiving department

What is The In-Line E-Vac Vacuum Generator?

These single stage, cylindrical units are compact and easy to mount at the point of use. They can be held in place by threading them directly onto a compressed air line or with the use of a mounting clip. There are 7 models available for use with porous materials, like cardboard, with vacuum levels up to 21” Hg (71 kPa) and vacuum flows up to 18.5 SCFM (524 SLPM). There are 7 models available for use with non-porous materials, such as glass, with vacuum levels up to 27” Hg (85kPa) and vacuum flows up to 15.8 SCFM (447 SLPM).

EXAIR manufactures two versions of the In-Line E-Vac – Low Vacuum for porous materials and High Vacuum for non-porous materials. The application will dictate which type of vacuum is most suitable.

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).

Increased Energy & 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 centralised 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 the 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. CAA’s team can help you to select the E-Vac vacuum generator and vacuum cups that provide the right amount of lifting capability while minimising the amount of compressed air usage.

Performance

In-Line E-Vac High Vacuum Generators For Non-Porous Applications

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. There are 7 In-Line models that vary by flow and vacuum level. Choose the E-Vac by the SCFM (SLPM) flow that best suits the performance needed for your application.

E-Vac Kits give you the ability to experiment with an assortment of vacuum cups. Kits include a muffler, an assortment of (4) pairs of vacuum cups (closely matched to the performance of that E-Vac), (2) straight, (2) elbow and (1) tee vacuum fitting, 3, (10′) of vacuum tubing and a mounting clip.

E-Vac Deluxe Kits include the same items as the standard kit with the addition of an automatic drain filter separator for the compressed air supply and pressure regulator (with coupler).

In-Line E-Vac Vacuum Generators for non-porous applications.

The In-Line E-Vac with Standard Muffler is also available with your choice of accessories.

Other Applications For 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 a 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 analysed.

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 VacuumIn-Line High Vacuum, or Adjustable. The E-Vac type determines maximum vacuum available for lifting the part and vacuum cup selection.

Porous low vacuum generators max. vacuum = 21″ Hg (71 kPa)
Non-porous high vacuum generators max. vacuum = 27″ Hg (91 kPa)
Adjustable E-Vac vacuum generators max. vacuum = 25″ Hg (85 kPa)

2. Determine the weight of the part.

3. Multiply the weight by the vacuum cup safety factorfor the total vacuum cup capacity needed. See Choosing A Suitable Vacuum Cup

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 from chart based on maximum vacuum available (E-Vac type) and holding weight per 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.

Here is an example using the steps outlined above:

A sheet of material measures 914mm x 914mm (3′ x 3′) and weighs 11.3kg (25 lbs). Each sheet is in a stack and will be placed on a conveyor.

If it is porous like wood and positioned vertically: If it is non-porous like glass and positioned horizontally:
1. Choose a porous, low vacuum In-Line E-Vac. The maximum vacuum is 21″ Hg (71 kPa). 1. Choose a non-porous, high vacuum In-Line E-Vac. The maximum vacuum is 27″ Hg (91 kPa).
2. The weight is 11.3kg (25 lbs). 2. The weight is 11.3kg (25 lbs).
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). 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 25 lb. (11.3kg) capacity. At 21″Hg (71 kPa), the Model 900755 Vacuum Cup will hold up to 25.3 lbs (11.5kg). 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. At 27″ Hg (91 kPa), the Model 900754 Vacuum Cup will hold up to 20.8 lbs (9.4kg).
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. 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.

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.

Filters, Regulators, Valves & More

With proper filtration of dirt, moisture and oil from the compressed air supply, EXAIR compressed air products will operate for years with no maintenance required. Use a 5 micron or smaller filter separator on the compressed air supply. To prevent problems associated with oil, use a 0.03 micron or smaller oil removal filter on the compressed air supply. Pressure regulators permit easy selection of the operating pressure, providing infinite control of flow, force and air consumption.
