I’ve written in the past about how to identify an EXAIR part, specifically how to identify a Vortex Tube. I recently ran into a very similar situation, only this customer was having difficulty identifying a Line Vac that was installed on one of his machines. The Line Vac was installed to remove a small pin from their part and convey it out to a separate bin for disposal. Rather than purchasing an additional machine, they were trying to expand the line and build one themselves. They reached some difficulty when trying to identify the EXAIR part that was installed and reached out to us for help.
Our Line Vacs come stock in (4) different materials of construction: aluminum, 303 stainless steel, 316 stainless steel, and for our Heavy Duty models a hardened alloy steel for abrasion resistance. The hardware used on the aluminum models is a black oxide screw whereas the others all have stainless steel hardware. Since his had black oxide hardware, it was easy to discern that this was in fact an aluminum Line Vac. To differentiate between the 303 and 316 models, we make a small cut around the circumference of the part. The outer appearance of the Heavy Duty is easily distinguishable.
Once we’ve identified the material of construction we must measure the O.D. of the inlet and outlet. By cross-referencing this measurement with the dimensions in our catalog you can then identify exactly which model number Line Vac that you have. In this scenario, the customer had to remove the Line Vac from the machine to measure the O.D. of the cap. The manufacturer of the machine had turned down the outside of the outlet on the body. Fortunately, he sent us a photo which clearly showed that this was the case. Based on his measurement, I determined that he had an EXAIR Model 6079 that had been modified. He was able to immediately place an order for the replacement and it shipped that day!
If you have an EXAIR part somewhere in your facility that you’re struggling to identify, give an Application Engineer a call. Through a series of investigative questions (and hopefully the help of photos!) we’ll be able to determine the model number that you have and clear up any uncertainty.
