Heavy-Duty Line Vac Air Operated Conveyors Climbing to New Heights

During this COVID-19 shelter in place circumstance, as an avid outdoors man (specifically I do a lot of rock climbing), things have been frustrating to say the least. In the Cincinnati area with all the climbing gyms closed down climbers are flocking to their local crag to get that last climb in for the foreseeable future. My local crag is Red River Gorge in Rodgers, KY. As the climbing season has now ended due to this pandemic the season of indoor (aka at home) training has began to ramp up with everyone hitting their hang boards and starting harder work out routines in their free time. It came to my mind that now is the time to also check out my old gear and see what needs to be replaced.

Climbing gear needs to be strong, durable and light weight so that the gear does not fail you in your time of need. If properly set up, a climbing rated carabiner can withstand a force of 24 kN or 5395 lbs. Every bit of climbing material needs to be taken care of and replaced when the time comes. When your life is hanging by the gear that you use durability and maintenance is the difference from dropping or not dropping from a cliff. But climbing equipment isn’t the only thing that you want to be strong and durable; you also want your material handling equipment as well.

At EXAIR we strive to make strong, durable, and maintenance free compressed air products. One such product is our Heavy Duty Line Vac air operated conveyor; the Heavy Duty Line Vac is a stronger and more durable version of the standard aluminum Line Vacs. The body and cap of the Heavy Duty Line Vac is made out of a hardened alloy which provides abrasion resistance. This means that it can withstand materials such as sand, salts, steel shavings, tumbling and blast media, etc. They are available from 3/4″ through 3″ and are used with identical sized hose, tube or pipe. 

Heavy Duty Line Vac

The Heavy Duty Line Vac is also designed to lift heavier material and move it farther and/or higher. Materials such as steel shot, garnet and ground glass are common. More power also increases the distance materials can be conveyed. Heavy Duty Line Vacs convey 6 times farther than standard Line Vacs.

The Heavy Duty Line Vac also comes with either smooth connections or threaded connections. The smooth connections allow for our reinforced PVC conveyance hose to attach to the ends using a standard hose clamp. If a flexible hose is not appropriate for your application the threaded connections allow the line vac to connect to a hard pipe. Both types of connections are interchangeable to fit your conveyance needs.

If you have questions about our Heavy Duty Line Vacs, or would like to talk about any of the EXAIR Intelligent Compressed Air® Products, feel free to contact EXAIR and myself or any of our Application Engineers can help you determine the best solution.

EXAIR Vacuum Generators and Accessories

So, you’re looking at picking out a vacuum generator for your application but don’t know what accessories you need? Well here is a little overview of EXAIR’s E-Vac system’s accessories that you have to choose from. The E-Vac has a variety of uses from pulling a vacuum on a chamber to lifting Concreate cinder blocks. Here at EXAIR we offer everything that you may need to get started; this includes mufflers, vacuum cups, hose, and fittings.

Vacuum cups for E-Vac generators

Every time I hear someone talking about trying to pick something up the first line that comes to mind is “The claaaaaaw.”. But sometimes a claw or gripper isn’t the answer for the solution; using a variety of vacuum cups one can practically pick up almost anything. We offer four different kinds of vacuum cups to choose from stock; available are small and large Round, Oval, and Bellow styles. Round cups are more suited to being used on smooth, flat surfaces. Oval cups provide the most vacuum due to the larger surface area making them ideal for lifting heavy loads. The Bellows style is best suited for textured or uneven surfaces; the folds provide a collapsible area that allows the cup to compress and seal on the uneven surface.

EXAIR’s Standard and Straight Through Muffler

Next up is the mufflers; EXAIR’s mufflers do just that, they muffle down the sound generated by the E-Vac. There are two different types of mufflers that are available; these are the Standard and the straight through mufflers. The Standard muffler is designed to be attached to the discharge end of an in-line      E-Vac and has a closed end. These are best suited for applications that are free from dust and debris. The straight through muffler is open all the way through and are more suited to applications were dirt dust and debris is present. The straight through style also offers the best sound level reduction, up to 26 dBA.

Lastly the E-Vacs have an NPT threaded connection that will allow for a suitable connector to be properly installed. From here different connectors can be used to attach the various amounts of vacuum cups. The connectors provided are Push-In Connector Type Fittings of assorted styles available with our polyurethane tubing to make the installation and plumbing a cinch.

If you have any questions or want more information on EXAIR’s E-Vacs and their Accessories. Give us a call, we have a team of application engineers ready to answer your questions and recommend a solution for your applications.

A Cold Winter’s Chill and Vortex Tubes

Two weekends ago I had the pleasure of flying out to meet my friend in Colorado Springs and ski the weekend at Breckenridge. As an avid skier Breckenridge has been one of the resorts I have been wanting to ski since I started skiing out west. The weather was amazing and I couldn’t ask for better; the Saturday blue skies and cool breeze followed up by a Sunday of snow fall. The Trip was a dream come true. Breckenridge is specifically known for having high winds that howl across the peaks that stand at a max of 12,998 ft. above sea level. These chilling winds would freeze just about anyone if you aren’t dressed prepared for them as they blow right in your face on the lift. As I was sitting on the lift with these cold winds blowing in my face it brought to mind EXAIR’s Vortex Tubes, Cold Guns, and Cabinet Coolers.

EXAIR’s Vortex Tubes and similar products provide everything from a cool blast of air to a frigid breeze to cool off various parts and products. In a lot of smaller milling and grinding applications the Cold Gun has been used as a replacement to costly coolant-based alternatives. Vortex tubes have been used in cooling applications since 1945 and assist in everything from stress testing electronics to cooling down plastic parts during ultrasonic welding.

 Vortex tubes use a source of compressed air to create a hot and cold stream of air coming out on opposite ends of the device. This means that not only can the vortex tube be used for cooling but also heating applications. In one case a vortex tube was used to heat up an adhesive before it was sealed to get a better adhesion. Although the vortex tube can be used for heating purposes those applications are few and far between as usually a heating element or other heating source is more applicable.
Vortex tubes are quickly adjustable, just as the winds of Breckenridge can change from being a breeze to almost blowing you off of the mountain. Weather in the mountains is always varying and so are EXAIR’s Vortex Tubes.

If you have any questions or want more information on how we use our vortex tubes to improve processes all over industry. Give us a call, we have a team of application engineers ready to answer your questions and recommend a solution for your applications.

Heavy Duty Pneumatic Vacuums: EXAIR’s Heavy Duty Dry Vac

Are you tired of not being able to pick up your heavier material with your current vacuum? Is your material abrasive, does it have a high bulk density? Are you tired of your electric vacuum constantly burning up its motor? EXAIR’s Heavy Duty Dry Vac system is engineered with the power to vacuum heavy materials, materials with high bulk densities. It’s material resists abrasion from the harshest of debris, like garnet, glass, tumbling media and steel shot. This system has no moving parts which means no motors or bearings that can fail on you.

The Heavy Duty Dry Vac requires only 68 SCFM at 80 psig of compressed air to operate. Using a hardened alloy construction for the vacuum generator gives the system an increased resistance to abrasive material including sand and blasting material. Depending on your application and the volume of material you need to vacuum we provide 3 different sizes, 30-gal, 55-gal, and 110-gal.  

Heavy Duty Dry Vac in operation

The design of the Heavy Duty Dry Vac allows the system to be mounted on your own drum and has a 0.1-micron filter bag installed on the center of the drum to allow air to escape and keep the material inside the drum. The enlarged size of the filter bag allows it to last longer before needing to be cleaned and/or changed out. Under the lid EXAIR has design features to aid in lowering the sound level down to only 82 dBA.

The Heavy Duty Dry Vac system comes in three different kits; these kits are the Standard, Deluxe, and Premium systems. The basic kit come with the Vacuum generator, the lid, and a lock ring to seal the lid onto your drum. The kit also includes the filter bag, 10’ Static resistant hose, and the aluminum chip wand. The basic system is everything that you need to get started with your own drum.
The Deluxe system Includes everything that the basic Heavy Duty Dry Vac system comes with but adds a few items: A magnetic tool holder, a 2-piece double bend wand, 12” floor tool, 11” crevice tool, 24” crevice tool, a skimmer tool with a detachable brush, and a 3-1/2” diameter bust brush with conductive bristles. All of the tools that come in the Deluxe system are of Aluminum construction. This system also adds the drum dolly to make it easier for you to move the system around.

If you do not have your own drum the Premium system includes everything Deluxe system does except adds a drum. Each Drum vac system comes in one of the 3 sizes listed.
For more information on EXAIR’s Heavy Duty Drum Vacs or any EXAIR‘s Intelligent Compressed Air® Product lines, feel free to contact EXAIR and myself or any of our Application Engineers can help you determine the best solution.

No Drip Atomizing Spray Nozzles: Overview

Are you tired of your dripping nozzle leaving puddles on your equipment and making a mess? Do the liquids you use to treat or coat your materials cost you a great deal of money? EXAIR’s No Drip Atomizing Spray Nozzles have been engineered eliminate drips; these patented nozzles contain a spring mechanism that when the air pressure reaches above 30 psig the valve will open allowing the liquid to escape out.

EXAIR No Drip Air Atomizing Spray Nozzles come in three styles. Internal mix, External mix and Siphon fed. 

One of the most commonly used types of No Drip Atomizing Spray Nozzles is the Internal Mix. The Internal Mix nozzle mixes the liquid and the air inside the cap and produces the finest droplet size out of the three. Due to the fact that the liquid and air are mixed in the cap, Internal Mix nozzles are used on liquids that have a lower viscosity (less than 300 cP). This means that they are usually used on liquids such as water, water soluble/diluted lubricants, lightweight oils, or rust inhibitors.

External Mix No Drip Atomizing nozzles have the highest flow rates and allow the air and liquid flows to be adjusted independently. These are best when precise liquid flow is needed. External mix nozzles can be used when the liquid viscosity is above 300 cP. 

Siphon Fed No Drip Atomizing nozzles require no liquid pressure and can be use dwith gravity fed liquids or siphon liquid from a height as much as 36 in. (91cm). These can be used with liquids up to 200 cP. 

No Drip Atomizing Nozzle
The No Drip Atomizing Spray Nozzles share the same spray patterns as our line of standard atomizing spray nozzles. This means that they are available in Narrow Angle Round Pattern, Wide Angle Round Pattern, Flat Fan Pattern, Deflected Flat Fan Pattern and 360° Hollow Cone Pattern. Along with the five different spray patterns they also come in three different inlet sizes of 1/8″, 1/4″ and 1/2″ NPT.
No Drip Flat Fan Spray Nozzle
Each NPT size also comes in a variety of different sizes in the corresponding spray volume. For example, the 1/8” No Drip Internal Mix Flat Fan Nozzles have for different Nozzles with a flow rate ranging from 3.47 GPH to 28 GPH (13.2 LPH to 105.99 LPH). This gives the No Drip Internal Mix Atomizing Nozzle 36 different variations to fit your application.
No Drip Siphon Fed Round Pattern Atomizing Nozzle
The normal applications for No Drip Atomizing Spray Nozzles Include but not limited to the following:
  • Painting
  • Coating
  • Rinsing
  • Cooling
  • Quenching
  • Wetting,
  • Humidification
  • Dust Control
  • Snow Making

Or any application where drips can harm a products finish or waste valuable liquids.

Swivel Fittings: Adjusting Their Way Into Your Application

Ever had that spot that you needed to blow off but no matter how hard you tried you couldn’t reach the spot with piping? Well here at EXAIR we’ve got a solution for you; Introducing the swivel fitting! When blowing off various parts it is better to have an angled sweep of air rather than blowing directly across or directly down onto the part. EXAIR’s Swivel fittings provide a movement of 25 degrees from the center, meaning a total of 50 degrees.

EXAIR’s Swivel Fittings Adjusted
Regardless of size of the air nozzle we can provide a swivel fitting to fit all of our nozzles starting at an M4 Thread up to a 1” NPT. The M4 (4mm), M5 (5mm), and M6 (6mm) swivel fittings come with a Female NPT to screw the nozzle into and a Male NPT to attach to the swivel fitting to the pipe. For our 1/8” Fitting up to the 1” Fittings a male NPT is used to connect the Nozzle and a female NPT is used to connect to the pipe. The swivel fittings can easily be adjusted by either loosening or tightening the center hex nut.
EXAIR’s Family of Swivel Fittings
If the swivel fitting doesn’t give you the adjustment that you need, they can be coupled with our Stay Set Hoses to give extra adjustment and positioning. Our stay set hoses come in lengths of 6” all the way up to 36” and provide easy positioning for your application. Of course, these hoses can also be used without a swivel fitting. 
EXAIR’s Family of Stay Set Hoses
Swivel fittings are not used with just air nozzles, in many cases swivel fittings have been used with our smaller Air Amplifiers and our 3” Air Knifes.

For more information on EXAIR’s Swivel Fittings, Stay Set Hoses, or any EXAIR‘s Intelligent Compressed Air® Product lines, feel free to contact EXAIR and myself or any of our Application Engineers can help you determine the best solution.

Custom Air Amplifiers: Customization to Fit Your Needs

EXAIR’s line of Air amplifiers can be found in thousands of applications across the world from everything as simple as blowing parts off to exhausting fumes. The Air Amplifier comes in two different styles either the Super Air Amplifier or the Adjustable Air Amplifier. Super Air Amplifiers come in a stock Aluminum Body with a diameter that ranges from ¾” to 8”. This differs from the Adjustable Air Amplifier which comes in either type 303 Stainless Steel or Aluminum and are Sized from ¾” to 4”.

Super Air Amplifiers are supplied with a .003″ (0.08mm) slotted air gap which is ideal for most applications. Flow and force can be increased by replacing the shim with a thicker .006″ (0.15mm) or .009″ (0.23mm) shim. Model 120028 is supplied with a .009″ (0.23mm) air gap. A .015″ (0.39mm) shim is available for Model 120028.

Even though there is a wide variety of sizes and materials for the Stock Air Amplifiers they don’t always match a customer’s specific need or application. Over the years EXAIR has produced a slew of different custom Air Amplifiers for a customer’s specific need and the following are just a few of what we have done.

  • Depending on the environment certain specific materials may be required like the food industry which requires specific Stainless Steel for various applications. One customer had a special PTFE plug made for the Adjustable Air Amplifier to help pull a sticky material through the process. The PTFE helped prevent the material from depositing on the inside diameter of the Amplifier.
  • For applications where mounting may be an issue, special attachments have been made to assist. For instances where an Amplifier may need to be mounted to a pipe, we manufactured a custom Stainless-Steel Adjustable Air Amplifier with class a 150 raised face flange.
  • Applications that are in a hot environment may require a special high temperature version which has be developed to operate in areas up to 700°F. The High Temperature Air Amplifier was so widely sought after that we turned it into a stock item.

No matter what your application is EXAIR is capable to work with you to create custom solutions for your application. Whether you need a different material, size or shim thickness, EXAIR is able to meet your requirements. These Air Amplifiers represent only one of our many product lines that can be custom made to your specifications.
