EXAIR’s Line Vac: An Ideal Solution For Scrap Trim Problems

I’m not a pro in the kitchen, but I know my way around most of the stuff in my kitchen drawers & cabinets. I know the value of sharp knives, cast iron skillets, crock pot liners, etc.

And I HATE plastic cling wrap.

That’s not to say I don’t USE plastic cling wrap…it might be about the quickest and handiest way to deal with open containers going back into the refrigerator, and it’s great for wrapping up leftovers that I can’t find the right container, or properly sized zipper lock bag for. It’s just that the tendency of cling wrap to, well, cling to itself, is very frustrating. Especially when I have a balled up handful of the awful stuff before I’ve even cut the piece I want, using the serrated edge of the box it comes in.

It turns out, I’m not the only one who suffers such aggravation. I had the pleasure of talking with a custom packaging materials producer who uses a bunch of our Line Vac Air Operated Conveyors to convey scrap trim away from their cutting lines to be recycled. Most of these were larger units, because the material was stiff and could be uneven, requiring the larger throat diameters of the 3” and 4” Line Vacs. A new material for them, though, was similar to the dreaded plastic cling wrap. It’s only about 1” wide, and the larger Line Vacs were plenty strong enough to convey it, but it turned out, the clinginess did its job all too well, and it would adhere to the inside wall of the hose. This would quickly crumple up (like the unusable handful you end up with when you don’t hold it just right while cutting it), and clog up the hose, making them stop what they were doing until they could fish it out.

They were wondering if there was a better solution. I thought that a smaller diameter Line Vac might keep the vacuum flow’s velocity high enough to prevent the trim from adhering. I offered the services of our Efficiency Lab to test my theory, and, after trying it with several different Line Vac sizes, we were able to consistently convey it at their desired rate of 700 feet per minute, using a Model 6081 1” Aluminum Line Vac. We found it best to install the Line Vac right in the middle of the specified 20 foot run, by using 10 feet of our Clear Reinforced PVC Conveyance Hose on both the suction and the discharge. This setup is a bit different than the typical 3 feet of vacuum hose we recommend for conveying dry bulk materials, but that’s why we test.

The Line Vac conveys scrap trim quickly and easily, and can be sized for most any product.

If you’ve got a frustrating application that an EXAIR Intelligent Compressed Air Product might be the solution to, give me a call. We can talk about what we can offer for you to try, or what we can test for you in our Efficiency Lab.
