EXAIR Line Vac Helped out in “Sticky” Situation.

Please allow us to introduce Vivek Engineers ( We are a group of qualified Engineers with an experience of over 25 years in the field of Automation with Pneumatics and plant solution products. We are the Authorised Distributor of EXAIR - USA product in India.

Recently Our Principal,Exair served to An office furniture manufacturing company which wanted to increase their production by installing two new automated edge banding lines in their facility.  These lines are designed to glue a plastic film to the outside edge of laminated wood panels.  Each system contained four gluing stations, one on each side of the line, positioned 15 meters apart.  Their goal was to duplicate their existing lines but with less floor space (and haven’t they all heard this one).  They were having issues in fitting the same type of equipment inside that limited amount of space.  Since they could not change the automated lines, they had to look at their next biggest system; the vacuum conveying system.  It consisted of a motor, a vacuum pump, an accumulator, and a control panel.  So, it had a large footprint (reference sketch below).

From the vacuum system, they branched out with conveyance lines that were fitted with a large actuator valve to open and close at certain times for filling.  With this configuration, they had a centerline distance between lines of 11 meters.  This conveying system was not only large, but very expensive.  They had to find an alternate method in order to add their new process lines.  They took to the internet and came across the EXAIR Air Operated Conveyors or, Line Vacs.

During their discussion, Clients gave to our principal their design specifications required for the application. The glue pellets were 5.5mm in diameter and had a bulk density of 1100 Kg/M^3.  The gluing stations would only use 50 kg/hr  per hopper at full capacity.  The opening of the hopper was positioned 4 meters from the ground level above the processing line.

With these requirements, the EXAIR Line Vac was the perfect product to use.  our principal suggested using one of a model 6982 Aluminum Line Vac Kit per hopper.   This kit comes with a 1 ¼” Line Vac, a mounting bracket, a filter separator, and a regulator.  The Client could mount them near the super sack of glue pellets, individually control each Line Vac, and convey the desired amount of material to each hopper.  At a 4 meter height and a maximum 15 meter distance, the model 6982 has the ability to convey nearly 150 Kg/hr at 5.5 bar.  The pressure regulator that is included in each kit could be used to “dial in” the required amount of material at the different distances.  With its compact size, 61mm diameter by 91mm long, it could fit nicely near the machines without taking up valuable floor space.

The Client was able to mount the Line Vac Kits next to the lines which allowed them to move the edge banding lines closer together.  They were able to decrease the centerline distance from the original system of 11 meters to a distance of 6 meters.   Thus, solving the above issue by gaining valuable floor space.  As an added value in conveying with EXAIR Line Vacs, they were able to reduce the cost by 1/10 of the original vacuum system.

The design of the Line Vac makes it very easy to mount, setup, and use right away. They do not have any moving parts or motor bearings to wear, making them very reliable and long lasting.  In addition to that, the cost comparison between the large vacuum system and the EXAIR Line Vacs has a great financial benefit as well.  If your company needs a compact, simple, inexpensive conveying systems to move product, you should contact an Application Engineer to see if we have an Air Operated Conveyor that will suit your application.
