EXAIR’s Line Vacs, or Air Operated Conveyors, provide an efficient method of converting ordinary pipe, hose or tubes into powerful in-line conveyors. To accommodate the wide variety of unique problems manufacturers face, EXAIR has the ability to customize and tailor Line Vacs to different specifications. Certain processes may require customizations like unique sizes, shapes and materials in order for the product to be a perfect fit for their system. EXAIR will work in collaboration with the customer to fabricate the best possible Line Vac solution for easy and efficient conveyance.
I worked with a customer to design a special Line Vac. They needed 3” ANSI 150# Flanges on a 3” PDVF Line Vac. So, we had a special material with special ends to suit their specific needs. The PVDF with Hastelloy hardware was for chemical resistance, and the flanges were used to mount onto their piping system. As with many of our Line Vacs, we can turn a normal piping system into a conveyance system for waste, parts, or bulk materials. For this customer, they needed a backup system for a fume hood. With electrical vacuums and blowers, loss of power or motor failures can cause a momentary lapse in fume removal. Since the chemical material that was used in the hood was dangerous, they needed a reliable source to extract the fumes. The Line Vac does not have any moving parts or require electricity. The Line Vac only uses compressed air or gas to make it operate. For this customer, they attached nitrogen to the special Line Vac to work when there was a power failure to protect the workers in the area.
For customers with space limitations, smaller sizes can be created while still offering the same capacity for conveyance. In situations where the Line Vac requires a specific flange mounting option, EXAIR can accommodate. Locations requiring custom mounting holes, brackets or inlet positions are possible. For applications where stock aluminum, or 303 and 316 stainless steel won’t work, alternate materials like PVDF, PVC or PTFE can be utilized. Even in extreme environments, EXAIR can produce both heavy-duty or high-temperature iterations to handle even the toughest material or conditions. Other details like the customer’s particular hose size, or pipe threading are specifications that EXAIR will have no problem accommodating.
Stock Line Vac models include standard, Heavy Duty, Ultra Duty, Light Duty and Sanitary Flange. All versions can be customized with different connections and materials to meet customer’s specific needs. If there’s a process in your facility that could benefit from a product like the EXAIR Line Vac, act fast! Now through October 31st, you’ll receive a FREE 1104 3/8” Super Air Nozzle as a promotional item with the purchase of any EXAIR Line Vac with a qualified order in the U.S. For any help solving specific conveyance problems, you can contact an Application Engineer. We will be happy to help.
If you’re performing any type of manual transfer of raw material in your processes, it might be time to take a closer look at EXAIR Air Operated Conveyors, or Line Vacs. The Line Vacs are designed as an ideal solution for the transfer of bulk materials from one point to another. They have no moving parts to wear, are very compact and easy to install, remove safety concerns, and do not require maintenance. I will cover the many selections that EXAIR currently offers.
Air Operated Conveyor
The Line Vac can move large volumes of material over long distances with just a small amount of compressed air. The compressed air is injected through directed holes that produce a vacuum on one end and high-volume output flows on the other. The Line Vacs are manufactured in several different materials and sizes, and with a few different options for connection style. Adjusting the flow of material is extremely simple and can be controlled by regulating the air pressure upstream of the Line Vac.
Lightweight and durable aluminum is the most popular choice, but we make them in stainless steel (Types 303 and 316) for heat and corrosion resistance. For extreme heat, the High Temperature option affords protection to 900F (482C) in either 303SS or 316SS.
Standard Line Vacs are offered with a smooth inlet/outlet designed to be used with any smooth-bore conveyance hose. These Line Vacs are offered in aluminum sizes from 3/8” (10 mm) up to 5” (127 mm), and in 303 and 316 stainless steel from 3/8” (10 mm) up to 3” (76 mm). Clear PVC conveyance hoses are available for 3/8” (10 mm) up to 3” (76 mm) I.D. from stock in 10’ (3 m) increments up to 50’ (15 m).
If you’d rather use rigid pipe, Threaded Line Vacs are also available directly from stock. With identical performance to the standard Line Vac, the Threaded Line Vacs are offered with NPT threads on both the inlet/outlet in sizes ranging from 3/8” NPT to 3” NPT in aluminum, 303, or 316 stainless steel.
For higher conveyance rates and abrasive materials, EXAIR offers Heavy Duty Line Vacs in the same manner as our standard or threaded units but are constructed from a hardened alloy steel. The Heavy Duty Line Vacs are offered with both smooth and threaded connection styles from ¾” (19 mm) up to 3” (76 mm). The Heavy Duty Line Vacs are ideal for media that is abrasive in nature or for applications requiring higher conveyance rates over longer distances.
The Ultra Duty Line Vacs are designed to handle the conveyance of extremely abrasive materials. The bodies are made from the same material as our Heavy Duty Line Vacs, but we added a ceramic insert. The overall length is a bit longer to accommodate this insert, but the flow rate, distance, and conveyance rates are exactly the same. This ceramic insert is placed where the conveying material hits the surface on the exhaust side, making it more durable and longer lasting. We currently offer them in 1 ¼”, 1 ½”, and 2” for hose connections.
For applications where you only need to convey small volumes over short distances or particularly lightweight materials, our Light Duty Line Vacs would be an ideal solution. The Light Duty Line Vac is available in sizes ranging from ¾” (19 mm) to 6” (152mm) and consumes a bit less compressed air than the standard and heavy-duty versions. This style of Line Vac is only offered in aluminum construction and for use with smooth-bore hose.
Last, but certainly not least, is the Sanitary Flange Line Vac. The Sanitary Flange Line Vac is the best method for conveying materials in systems that require frequent or mandatory cleaning. Utilizing ISO 2852-compatible clamp-style sanitary flanges, they can be easily removed from the system for periodic sanitization. These are offered in sizes ranging from 1-1/2”(38mm) up to 3” (76mm) in 316SS construction from stock. They are ideal for applications in the food and pharmaceutical industries.
If none of these stock Line Vacs suit your process, we still have more options!! Custom units are available with varying styles of flange connections; Hybrid NPT threaded/smooth units can be done with stock components, we’ll even manufacture in special materials. At EXAIR, we take pride in offering custom solutions for customers that may require something just a little different from what is readily available on the shelf.
