EXAIR Line Vacs use a small amount of compressed air to generate a powerful vacuum by a Venturi effect. The unique design of the generator creates a high velocity of air to create a low pressure on one side and a powerful thrust on the other. The Line Vac can pick up and move solid material from light and fluffy batting to dense, heavy and abrasive material and parts. They can transfer product horizontally up to 100 feet (30 meters) away and vertically up to 20 feet (6 meters) high. You can watch a video on the operation of a Line Vac HERE. Compared to other vacuum or conveying systems, the EXAIR Line Vacs are very quiet, rugged, and powerful. They are exceptionally simple to install and solve many “bucket and ladder”, loading and scrap removal applications. EXAIR manufactures a variety of Line Vacs in different sizes, styles, and materials to best fit your application.
The standard Line Vac is the most versatile product in this family. EXAIR stocks a wide range of sizes, materials, and styles to target the best solution for moving material. We have two types of connections, slip-on, hose barb type ends for hose connections and male NPT threaded ends for pipe connection. EXAIR can swap the connections with a slip-on hose on one end with a threaded connection on the other. They range in diameters from 3/8” (10mm) up to 5” (127mm). We manufacture the Line Vacs in aluminum, 303SS, and 316SS; but don’t let that deter you if your need them manufactured in any other type of material. We have high temperature models that can withstand temperatures up to 900 deg. F (482 deg. C). These Line Vacs work great in applications for loading plastic pellets in hoppers, discarding scrap pieces, trim removal, and transferring material. If an operator has to carry a container of dry material and climb stairs, a Line Vac could be a much better alternative.
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 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.
Both the Standard and Heavy Duty Line vacs can be offered as Threaded Line Vacs which converts the smooth OD for hose slip over to a Male NPT to connect common plumbing fittings to they are both available in a range of different materials: Aluminum, Type 303 Stainless Steel, Type 316 Stainless Steel, and as a Heavy Duty conveyor constructed of a proprietary hardened alloy steel for use in abrasive applications.
Each style of Threaded Line Vac is also available as a High Temperature option. By replacing the traditional o-rings with graphite seals, we’re able to provide a solution capable of withstanding temperatures up to 900 °F!!!
EXAIR Line Vacs are also sold in kit format. A kit will include a filter, regulator and a bracket. (A bracket is not sold with the Light Duty Line Vac kits.) The filter will help keep the compressed air passages inside the Line Vac clean as well as the product that it is conveying. The regulator is a great tool to increase and decrease pressure as needed to vary the conveyance rates for better control. The mounting bracket allows the user to securely mount the Line Vac to a sturdy base for support.
