Cleaning up a Dirty Situation with EXAIR Ultra Duty Line Vacs

Published on by John BallLeave a comment

A mining company was moving tons of clay for processing.  They were having some housekeeping issues as the clay would collect under conveyors, on the tracks, and on the ground.  Currently, they use two people with shovels to scoop the clay into 55-gallon drums.  The conditions were tough while doing this backbreaking labor.  They contacted EXAIR to see if we could help. 

EXAIR offers a large line of Industrial Housekeeping Products.  But with the clay, it had some larger clumps that would be difficult for a 1 ½” vacuum hose.  EXAIR has another option to accommodate applications like these, the EXAIR Drum Cover.  Now, different diameters of Line Vacs can be used to vacuum or move material.  The Drum Cover allows the air to pass through a filter media while keeping the material inside the drum.  It is designed to cover the entire opening of the 55-gallon drum that they were using.  The Drum Cover has an opening at the top to accommodate hoses up to 3” (76mm) in diameter.  A strap with guide loops is used to secure the Drum Cover under a rolled-edge lip of the drum to easily move to different drums.  The fabric is also cleanable, washable, and reusable. 

For this customer above, they required an abrasion-resistant Line Vac to handle the clay material.  EXAIR offers the Heavy Duty Line Vac, made from hardened alloy steel, and the Ultra Duty Line Vac, which has a ceramic insert for better abrasion resistance.  The customer selected the model 172200 2” Ultra Duty Line Vac Kit.  The kit includes the Ultra Duty Line Vac, a filter, a regulator, and a bracket.  They also requested a conveyance hose to carry the clay to the drum from 20 feet (6 meters) away to give them range to move the suction end. The powerful suction and the larger diameter made it easy to fill a 55-gallon drum.

By utilizing the Drum Cover and the Ultra Duty Line Vac, they were able to keep up with the housekeeping.  They were also able to reduce the number of people as well as remove the ergonomic hazards of using a shovel.  If you wish to see if we can upgrade your Industrial Housekeeping Products, you can contact an Application Engineer at EXAIR.  We can help with cleaning up many different types of dirty situations.

Custom Pneumatic Conveyors for Unique Applications

Published on by John BallLeave a comment

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.

Installation Made Simple with EXAIR’s Threaded Line Vacs

Published on by Al WooffittLeave a comment

EXAIR‘s Line Vacs are a great option for bulk material transfer, or scrap or trim removal. They are especially good at replacing what we call the ‘bucket and ladder’ operation. Our most popular, standard Line Vacs are designed to be connected to a smooth bore hose for flexible conveyance. There are some applications where using fixed piping would make more sense. For this, we have our Threaded Line Vacs, available with threaded NPT connections, allowing you to turn ordinary pipe into a powerful conveying system.

Like with our standard Line Vacs, EXAIR’s Threaded Line Vacs use compressed air to generate a vacuum with the Venturi effect.  Our unique design generates high velocity airflow to create a powerful vacuum on the suction side.  Once the material reaches the throat area of the Line Vac, the compressed air will carry the product the rest of the conveying distance to the discharge. Your product can be transferred horizontally up to 100 feet, or vertically up to 20 feet!

We have models ranging from as small as 3/8NPT up to 3NPT for a variety of pipe sizes commonly found in an industrial facility. Our Threaded Line Vacs also come in a variety of materials. We stock aluminum models, suitable for most applications. We also have 303-type stainless steel where some corrosion or mild abrasion resistance is needed. For more critical applications, we also carry 316-type stainless steel models, often used in food and pharmaceutical applications. Finally, when you need to convey highly abrasive materials, such as sand or ceramic, we have our Heavy Duty Threaded Line Vacs.

We also sell our Line Vacs in a kit format which includes a properly sized filter, regulator, and a mounting bracket.  This adds value to mounting, controlling, and protecting the Line Vac.  Because our Line Vacs have no moving parts, you will not have to worry about any motors or bearings prematurely wearing out. They will be able to convey your bulk material for years to come.

If you are looking for a simple, low-cost and efficient way to convey bulk material, then an EXAIR Threaded Line Vac may be the right solution for you. Feel free to contact an Application Engineer to discuss your options!
