Customized for Your Process: Special Pneumatic Conveyors

For many, material conveyance is a necessary factor in their manufacturing and processing procedures. Much of the time our large array of different Line Vacs (air operated conveyors) can suit a large array of different conveying applications; but sometimes the stock item is just not the right fit for a specific application. Fortunately, since we manufacture everything here in Cincinnati, OH we have the flexibility to provide custom products throughout all of our 16 product lines. The Line Vac product line, even as large as it is, is a pretty common product for us to customize and manufacture. The following are a few examples of special Line Vacs that we have made in the past.

Liner Vacs connect to a hose, tube or pipe to create a powerful inline conveyor, powered by compressed air.

The Special Mini Line Vac:

This special was designed with barbed fittings for easier installation for a manufacturer of integrated circuit chips. It was used to remove microscopic debris. The small body and high vacuum flow made it a perfect fit for the confined working space.

The PVDF Line Vac:

This 1 ½” flanged Line Vac was designed using PVDF to provide a superior chemical resistance. In this case the unit was going to be exposed to a chloride wash which will corrode all versions of steel including stainless steel. The QF Flanges were also added to provide easy disassembly when the Line Vac was scheduled for cleaning.

The Special Flanged Line Vac:

This next special Line Vac was used to convey a measured granulated material into a pouch. The funnel side was loaded with the pre-measured material and pushed into a mesh pouch when the air was activated.

Special Flanged Refumigation Line Vac:

This flanged Line Vac was used to retrofit existing machinery to remove acidic vapors resulting from surface etching of a silicon wafer. Where this would typically be a nice fit for a Stainless Steel Air Amplifier, the existing exhaust piping was lengthy with many bends that would have caused back pressure on any Air Amplifiers. In this case, they needed the additional force from the Line Vac to overcome this downstream resistance.

EXAIR has a Line Vac for your Application!

With countless number of different Models to fit every application, EXAIR Line Vacs are used to convey everything from the lightest of packing peanuts to heavy steel shot.  They’re versatile, reliable, durable, and incredibly easy to install and operate. 

Line Vacs are EXAIR’s current promotion too, see the offer here.

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 pieces.  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 makes 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 for targeting the best solution for moving material.  We have two types of connections, slip-on ends for hose connections and 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.

Heavy Duty Line Vac: Hardened Alloy Construction and High Performance

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.

EXAIR’s Light Duty Line Vac

On the other end of the Line-Vac spectrum, EXAIR also manufactures the Light Duty Line Vac.   They use much less compressed air than the other Line Vacs which work great for moving lightweight materials over short distances.  They can also be used for removing smoke and fumes from a work area.  The Light Duty Line Vac ranges from ¾” (19mm) up to 6” (152mm) diameter for slip-on hose connections.  This two-piece design provides an effective way of moving material at a lower cost.  It can be used in applications like hopper loading, fiber tensioning, filling operations, and smoke removal.   For moving material within a short distance, the Light Duty Line Vac could be the proper product to use.

Model 161200-316 – 316 Stainless Steel Sanitary Flange Line Vac

Our latest engineering design within the Line Vac family is the Sanitary Flange Line Vacs.  They can fit within sanitary piping systems to convert pipes into a useful conveyor for bulk material and waste removal.  They use an ISO2852 flange for easy disassembly and cleaning to reduce bacterial entrapment.  They ae made from 316 stainless steel material for superior corrosion resistance.  They come in four different sizes to fit the sanitary flanges from 1-½” up to a 3” flange.  For sensitive applications where cleanliness is a major requirement, the Sanitary Flange Line Vac are manufactured for these conditions.

We are also able to make custom Line Vacs to mean any application, see an example of some unique to the application Line Vacs here, https://blog.exair.com/2020/07/01/custom-products-for-custom-applications/

With all of the EXAIR Line Vacs above, they can be sold as kits.  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 Line Vac clean as well as the product that it is conveying.  The regulator is a great tool to vary the conveyance rates for better control.  The bracket helps to mount the Line Vac to a sturdy base for support.  A useful accessory to conveniently hide the compact Line Vac for ease of use and operation.

If you have any questions on how our Line Vacs can help save you money give us a call! One of our application engineers will be happy to assist!

Bulk Material Transfer Made Simple: EXAIR’s Threaded Line Vacs

EXAIR’s Line Vacs are the ideal low-cost solution for bulk material transfer or trim and scrap removal. Available with NPT threaded connections, EXAIR’s Threaded Line Vacs allow you to convert ordinary pipe into a powerful conveying system for parts, scrap, trim, and other bulk materials. With performance identical to that of the Standard Line Vac, the Threaded Line Vac is available in sizes ranging from as small as 3/8 NPT and up to 3” NPT there’s a suitable Line Vac for most standard sized NPT pipe common an any industrial facility.

The Threaded Line Vac is 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 hardened alloy steel for use in abrasive applications. Where most materials or hard anodized coatings wear out or wear off over time, the Heavy Duty Line Vac is the ideal solution for heavy and abrasive materials. In addition to being abrasive resistant, it’s also more powerful and suitable for longer vertical and horizontal transfer distances.

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!!!

The conveyance rate through the Line Vac is infinitely adjustable by regulating the air pressure supplied to it. At lower pressures, the conveyance rate (and air consumption) will decrease. At higher pressures, the conveyance rate will increase. If you have a Threaded Line Vac with the standard performance but need just a little bit more, the option also exists for a High Power unit that would match the performance of the similarly sized Heavy Duty. This can be ordered from the factory with an “HP” prefix, or modified yourself. Check out our video to see just how simple it is to get more out of your Threaded Line Vac.

With all sizes and materials on the shelf and in stock, we’re able to get a solution out to you quickly. We’ll ship out the very same day for stock orders received by 2:00 ET. Backed by our Unconditional 30 Day Guarantee, you’re able to make sure it is the right solution for you before committing to keep it. If you have an application that could be better served with an in-line pneumatic conveyor, give us a call. We’ll be happy to help you determine the most suitable size for the application.

EXAIR’s Sanitary Flange Line Vacs: An Overview

EXAIR’s Sanitary Flange Line Vac is the ideal solution for customers looking to convey bulk materials in food & pharmaceutical applications (among others). Operating in the same manner as EXAIR’s smooth and NPT threaded Line Vacs, the Sanitary Flange Line Vac is available in (4) common flange sizes: 1-1/2”, 2”, 2-1/2”, and 3”.  All of EXAIR’s Sanitary Flange Line Vacs are constructed of Type 316 Stainless Steel for superior corrosion resistance.

There are different styles of flanges in industry. The Sanitary Flange Line Vac has been designed according to the flange standard outlined in ISO 2852. This standard was prepared by Technical Committee ISO/TC 5, Ferrous metal pipes and metallic fittings, Sub-Committee SC 1, Steel tubes. This is the second edition that replaces the first edition (ISO 2852:1974). The standard specifies the dimensions, tolerances, surface roughness, materials, assembling, and the hygienic requirements for the flange. These styles of flange are intended to be used with stainless steel tubes, specified in ISO 2037. ISO 2852 is considered an international standard, defining the connections used for non-permanent food-grade piping systems used within the pharmaceutical, food processing, dairy and agricultural industries.

In these industries, it’s required for the components to be thoroughly cleaned and sanitized. Using this type of connector, components within the piping system can be easily removed, sanitized, and then reassembled. A lipped flange with a grooved indentation is on each end of the pipe or Line Vac. A sealing gasket is then placed in between each section of pipe. A raised groove on either end allows it to seat onto the mating end of each flange. A clamp is then placed on the outside, forcing the sections together and compressing the gasket, creating an air-tight seal.

If your processes currently utilize sanitary flange piping, EXAIR’s Sanitary Flange Line Vac is the ideal solution to help you convey bulk materials from one point to another quickly, safely, and efficiently. If you have interest to test one out in your process, EXAIR offers an Unconditional 30 Day Guarantee on all stock items. They’re on the shelf now available to ship same day with an order placed by 2:00 ET!
