The Heavy Duty Line Vacs are made from a hardened alloy steel for abrasion resistance. The generators inside these Line Vacs are more powerful than the standard models; so, that they can also convey heavier materials at higher conveyance rates. They can reach rates as high as 40 lbs./min. (18.2Kg/min) of material. With the hardened alloy construction, they are great for sand blasting applications, ceramic, glass, garnet, tumbling media and steel shot. They are manufactured with inlet and outlet connections for ship-on hoses or threaded pipes. EXAIR stocks the Heavy Duty Line Vacs in the range from ¾” (19mm) to 3” (76mm) for both hose and NPT connections. These Line Vacs are our most powerful design with great wear resistance.
The table below gives a quick comparison of the EXAIR Light Duty Line Vac, Standard Line Vac & the Heavy Duty Line Vac models. The test shows the 2″ size in each model conveying Rock Salt over two different horizontal distances. As expected the Heavy Duty Line Vac conveys more material in less time!
The performance of the Heavy Duty Line Vac’s is nothing short of amazing! With vacuum ratings between -144 to -20 inches of water column, it is more than likely there is a Heavy Duty Line Vac model that will suit your application.
Models range from 3/4″ OD to 3″ OD either in smooth bore or NPT threaded models for the ultimate in versatility. The table below shows the different Heavy Duty Line Vac Models and their respective recommended kit, which includes a pressure regulator for fine tuning performance, filter separator to keep the compressed air supply clean and a mounting bracket.
