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.

Vacuum Generator System Selection – EXAIR E-Vacs

E-Vac Vacuum Generators are a highly efficient, versatile compressed air vacuum pump. Their versatility allows them to be adapted to many applications such as pick and place, clamping or vacuum forming. They’ve also been used in more unique applications like wood veneer pressing and basketball deflation.

EXAIR manufactures (3) types of E-Vacs – Low vacuum generators for porous materials, like cardboard, generating up to 21″ Hg with vacuum flows as high as 18.5 SCFM. Our high vacuum generators, designed for use with non-porous materials like glass or steel sheets, produce vacuum levels up to 27″ Hg and up to 15.8 SCFM of vacuum flow. The adjustable generators provide flexible vacuum performance, up to 25″ Hg and 81 SCFM,  which can be easily adapted to meet the application.

EXAIR E-Vacs provide instantaneous vacuum response, and are engineered for high efficiency to minimize air consumption.

 

When making a selection, there are a few key areas you want to consider:

Is the material porous or non-porous?

  • This will allow you to select the proper type of vacuum generator to fit the application and the type of vacuum cup best suited for the process.

 

What is the weight of the part and how will it be lifted?

  • If the part is being lifted where the vacuum cups will be positioned horizontally, like on top of a sheet of glass, you want to use a safety factor of 2 times the actual weight of the part. In processes requiring the cups be positioned vertically on the part, such as picking up a sheet of plywood and hanging it on an overhead conveyor, a safety factor of 4 would be used.

 

How many Vacuum Cups do I need?

  • Consider the quantity and placement to evenly distribute the weight for safely moving the material.
  • Depending on the maximum vacuum the generator produce, how much weight can each cup lift?
  • Make the cup selection per the following chart

 

Once you have selected the type and number of cups needed, you can then begin to look at which additional accessories items you might need.

  • Filters – supplying clean, dry air is key for maintaining optimal performance. An automatic drain filter  can be used to remove any water or contaminants in the supply line. If there is oil present, consider using an Oil Removal Filter.
  • Mufflers – help to reduce the noise level without restricting the airflow. We offer 2 different styles – Standard and Straight Through. Standards mufflers are a good choice where the supply air is clean and dry. These mufflers can only be used with the porous and non-porous generators. The Straight Through mufflers reduces sound levels by up to 26 dBA and are the better choice in processes where dirt or particulate may be present.
  • Tubing and Fittings – polyurethane tubing is available in 10′ sections up to 50′ for processes requiring the vacuum cups be placed in a location that wouldn’t allow for direct mounting to the NPT vacuum port on the generator or where multiple cups are needed. You want to keep the length of tubing as short as possible though for effective pickup and release time.
  • Check Valve – will maintain vacuum on the load if the supply pressure were to drop or be lost during operation.
