FAQ

  • How much material can be conveyed with a Line Vac?

    The conveying ability is affected by many factors, some of which are: Line Vac size, input pressure, conveying distance, vertical lift required, bends in the conveying path and type of material being conveyed. Since any one of these variables can have a dramatic effect on performance, it is suggested that the Line Vac be tested in the application to verify results. EXAIR Application Engineers can help determine if the Line Vac will work based on application requirements and assist in selecting the proper size Line Vac for the application.

  • Where should I position your Line Vac in my conveying system?

    Generally the Line Vac should be placed within 3 feet (or closer) of the suction point. It is always easier to blow material through a hose or pipe than it is to vacuum it through. Keep in mind, this is a guideline. If it is not possible to get the Line Vac that close, then place it as close as reasonably possible to the suction point.

  • What is the difference between the Line Vac, the Light Duty Line Vac and the Heavy Duty Line Vac?

    EXAIR has an expansive line of air conveying products. 

    • The Light Duty Line Vac performs best for short runs and small transfer rates
    • The Line Vac is designed for longer runs and greater transfer rates than the Light Duty Line Vacs
    • The Heavy Duty Line Vac is our most powerful and durable conveyor and is made of hardened alloy to resist abrasion. This construction allows the Heavy Duty Line Vac to convey more material in less time while helping to prevent premature wear.

    Call an Application Engineer for help in selecting the correct model for your application.

  • Can I convey liquid with a Line Vac?

    No, the Line Vac is not made for conveying liquids. The Line Vac will vacuum up some liquid, but not in a solid column of liquid. The liquid will mix with air and produce an output flow of atomized liquid that will spray out the end of the conveying tube.

  • Can I convey powder with a Line Vac?

    Yes, Line Vacs can convey powder. The discharge end of the Line Vac then has the potential to be very dusty. You need to separate the bulk powder from the air moving the powder. This is normally accomplished with a filter or centrifugal separator on the containment vessel at the discharge end of the Line Vac.

  • Do you sell hose for your Line Vacs?

    Yes, EXAIR sells spiral reinforced PVC hose from 3/8" inside diameter through 3" inside diameter. This hose is connected to the Line Vac with a worm gear hose clamp which is provided with the purchase of the hose.

  • Why can't I use your Line Vac with flammable materials?

    The Line Vac has the potential to produce a static charge caused by the material being transported.
