Super Air Amplifier Removes Unwanted Scrap Material

EXAIR Super Air Amplifier used for scrap material removal

A few months ago I wrote a blog about using a Super Air Amplifier to remove film from an application workspace and direct it to a waste container.  Earlier this week I had a different end user contact me about a very similar application.

In this application the Super Air Amplifiers are used in an automotive manufacturing facility to direct scrap material from car doors into the large bags below each station.  The scrap material is lightweight and proves to be problematic if not fed into a contained system.

This particular customer was in need of some assistance to duplicate their existing setup, shown in the photos above, into four more workstations.  So, they reached out to us to confirm the model number of the units (which have been “working perfectly”) based on dimensions.

Using the provided dimensions I was able to confirm the model number is 120022, our 2” Super Air Amplifier.  After confirming this I was able to provide a quotation for the requested Super Air Amplifiers, available to ship from stock.

If you have a similar application or think an EXAIR product may be able to help solve an application problem in your facility, contact an EXAIR Application Engineer.

When You Can Use An Air Amplifier, or A Line Vac, or…Either?

One of the key applications that we use to promote our Line Vac Air Operated Conveyors is scrap trim removal. In cases where a continuous feed of material needs to be carried away, a properly sized Line Vac is just the thing. They’ll generate a moderate amount of vacuum and conveyance air flow, which can move the material over significant distance, if needed.

I had the pleasure of talking to a long-time customer recently, who has been using EXAIR products to successfully remove the backing strip from a continuous feed of label roll. Instead of the Line Vacs, though, they’ve been using Model 6044 4” Aluminum Adjustable Air Amplifiers. The low density, lightweight film backing doesn’t require much air flow at all to move it, and they only need to carry it away a few feet.

Recently, though, they introduced a new product with a slightly wider label. The film backing for this has been catching in the 3.02” ID throat of the 4” Air Amplifier, making a BIG mess as it backs up into the machine. They called me for a solution, and I’m glad they did, because (spoiler alert) I had one.

Our Air Amplifiers and Line Vacs both generate a modest vacuum and moderate vacuum flow, but, because they use two different principles of operation to do so, the Air Amplifier makes for a very high vacuum flow, at a lower vacuum level, where the Line Vacs generate a higher vacuum, but a lower vacuum flow.

In some cases, the Air Amplifier is the obvious choice…if you’re moving something that’s already airborne, you don’t need a whole lot of vacuum; you just need the flow to keep it moving. In others, the Line Vac is better suited…like when you’re transferring the bulk contents of a shipping container, where you’ll need a higher vacuum level to pick it up.

In this particular case, either will work…it’s a lightweight material that’s already in motion (no significant amount of vacuum required there), so the throat diameter was the deciding factor: our Model 130400 4” Light Duty Line Vac has a 3.75” throat; which is more than sufficient to prevent jamming. The air consumption on the 130400 (58.5 SCFM @80 psig) is even in the same neighborhood as the 6044 (50 SCFM @80 psig,) so, operationally, it’s almost an even swap as well.
