EXAIR Heavy Duty Threaded Line Vac

EXAIR Threaded Line Vacs In Action!

EXAIR’s Heavy Duty Threaded Line Vac air operated conveyors can take ordinary threaded pipe and convert it into a powerful conveying system for pellets, scrap trim, bulk solids, chips, paper, small parts, sawdust, granules, and many other bulk materials. The Heavy Duty Threaded Line Vac attaches easily to plumbing pipe couplers, making it easy to build a complete system with parts that are readily available from your local home supply or hardware store.

They are available in 7 different sizes ranging from 3/8 NPT to 3 NPT and are made from a proprietary hardened alloy for superior abrasion resistance and performance. Heavy Duty Threaded Line Vac Air Conveyors are ideally suited for conveying large volumes of materials over long distances.  They eject a small amount of compressed air to produce a vacuum on the intake side and a high output flow from the outlet side.   Using a regulator to control the compressed air supply pressure, the rate of conveyance can be controlled to match what the application requires all while minimizing your compressed air usage!

The Heavy Duty Threaded Line Vac Kit includes a pressure regulator, filter separator to keep the air clean, modular coupler clamp (connects air regulator to filter separator, not shown below) and the mounting bracket for ease of installation.

Getting A Little More Vacuum and Flow

Last week, a customer called and indicated that he was a long time user of the model 6013 High Velocity Air Jet.

6013
Model 6013 High Velocity Air Jet

The customer was using the Air Jet to remove light trim scrap from a manufacturing process. The Air Jets utilize the Coanda effect (wall attachment of a high velocity fluid) to produce air motion in their surroundings.  A small amount of compressed air to the Air Jet is throttled through an internal ring nozzle at speeds above sonic velocity.  In the above image, this produces a vacuum at the left side, pulling in large volumes of surrounding air. By utilizing this vacuum pull and ducting the right side exhaust, air and scrap stream to a collection area. The customer assembled a small, efficient, and inexpensive scrap removal system.

The reason the customer had called in was there were some recent changes to the manufacturing process and needed a bit more vacuum force and flow to handle larger scrap and longer travel. We explored using a larger shim, but they were already using the largest size (0.015″.) We talked about the other products that EXAIR offers (Air Amplifiers, Line Vacs) that are used for scrap removal and conveyance.  But with any change, there are usually other modifications and approvals that must be dealt with in order to proceed. So we hit upon the Adjustable Air Jet, which is an adjustable version of the model 6013.

6019
Model 6019 Adjustable Air Jet

The model 6019 Adjustable Air Jet utilizes an adjustable air gap in place of the fixed shim thickness.  This allows for greater air flow, which results in greater vacuum and conveyance distances. As is the case for many customers, we gathered some additional data to help this customer make a decision. We set up each of the units and tested them at maximum capabilities, and the model 6019 was shown to deliver upwards of 50% greater flow.  The customer felt certain this level of performance would handle what the changed process would require, and best of all, no modifications to any part of the set-up would be required, simply install the 6019 where the 6013 was currently placed.

The High Velocity Air Jet is also part of the model 1909 Blowoff Kit, and is also used in the model 8193 Ion Air Gun and model 8194 Ion Air Jet, for Static Elimination applications. Of course, each can be purchased as an individual item.

To discuss your application and how an EXAIR Intelligent Compressed Air Product can make your process better, feel free to contact EXAIR and myself or one of our other Application Engineers can help you determine the best solution.
