Using Accessories to Boost Your Tools

I was once on a local theater’s website, ordering tickets to an upcoming show that my wife and I were excited to see. I had the option to pay online and have a digital code emailed to me in lieu of a real live paper ticket. Can you believe they wanted to charge me almost $2 A TICKET for that?!? I adamantly refused (by that I mean I clicked the mouse extra hard on the “Will Call” button before completing my payment)…and saved that $4 (almost) for something REALLY important.

The night of the show, there was a 20-minute line at the Will Call window. Folks who had opted for the digital code were doing a quick scan with their smartphones and walking straight into the theater. I used the $4 I saved to partially pay for a $10 glass of wine from a concession kiosk in the lobby, as a peace offering for my lovely bride. That was indeed “something REALLY important.”

Another time, I was ordering a sump pump backup system for our house. I had the option of paying extra for the deluxe system, which came with all the fittings and a special tool to make installation a bit easier. Even though the ‘deluxe’ system adder was probably a bit more than the cost of the fittings from my local hardware store, I paid the “convenience fee” and got the deluxe system anyway. For the record, during the installation, I realized I would have bought an incorrect fitting at the local store which would have forced an emergency trip while I had the water turned off in my whole house. THAT was an inconvenience I was glad to have avoided.

Similarly, you can buy any EXAIR product with, or without, accessories that’ll make for simpler installation, improved performance, and to ensure it does what you want it to do. Some of these are product-specific, but many are suitable (and recommended) for use with any of our products:

Filter Separators

Good engineering practice calls for point of use filtration for any compressed air operated device. Even if you have the best intake & discharge filters on your air compressor, trace amounts of contaminants can sneak through, pipes can rust, and water vapor that the dryer doesn’t catch can condense. Particulates can build up and eventually clog the tight clearances in many engineered compressed air products, and if you’re using air for cleaning, drying, etc., keep in mind that whatever’s in your air will get on your product. Moisture isn’t always as big of a deal, but it can freeze inside Vortex Tubes, Spot Cooling Products, Cold Guns, and Cabinet Cooler Systems. That’s why we include Filter Separators in our Air Knife, Air Wipe, Static Eliminator Products, Line Vac, Adjustable Spot Cooler, Cold Gun, and Cabinet Cooler System Kits.

Automatic Drain Filter Separators come in sizes from 1/4 NPT to 1-1/4 NPT, for compressed air flows up to 400 SCFM.

Oil Removal Filters

These aren’t always needed, but we have them if your application calls for it. Some of the “usual suspects” are food & Pharma (see above “whatever’s in your air will get on your product”), blowoff prior to painting (the smallest amount of oil on the surface causes a phenomenon known as “fish eye” and it looks exactly like that sounds), or when your compressor is known to have oil carryover.

When properly installed downstream of an Automatic Drain Filter Separator (left,) an Oil Removal Filter (center) will provide clean, oil free air to the Pressure Regulator (right) and all downstream components.

Pressure Regulators

One of our Six Steps To Optimizing Your Compressed Air System is to control the air pressure at the point of use to minimize air consumption. In other words, find the supply pressure for your product that gets the job done, so you don’t use any more compressed air than you have to. Like the Filter Separators above, these come with many EXAIR Intelligent Compressed Air Product Kits.

Pressure Regulators “dial in” performance to get the job done without using more air than necessary.

Mounting Brackets and Coupling Kits

Most of our Filter Separators, Oil Removal Filters, and Pressure Regulators can be attached to a wall, panel, etc., with a Mounting Bracket, and can actually be attached to each other with a modular Coupling Kit. These parts simplify the installation, ensure they are oriented correctly, and minimize the chance for air leaks.

Filters (left) and Pressure Regulators (center) can be mounted using Brackets, and they can be connected together with Modular Couplers (right).

Silencing Mufflers

Many EXAIR products are engineered to develop a boundary layer of low velocity air flow that greatly reduces the sound level during operation. Other products use a venturi mechanism to draw a vacuum (Reversible Drum Vacs and E-Vac Vacuum Generators) or a Vortex Tube to generate cold air flow. The air flow from these products cannot be subjected to back pressure, and, without anything to mitigate the sound pressure generated by the rapid pressure drop as the air exits, they can be quite loud. For these, we have Silencing Mufflers that, except for the largest & most powerful of these products, reduce the sound level to be compliant with OSHA Standard 1910.95 Maximum Noise Exposure Limits.

From left to right… Reclassifying Mufflers offer the highest noise level reduction, eliminate oil mist, and come in sizes from 1/8 NPT to 1 NPT.
Sintered Bronze Mufflers are low cost and compact, with threads from #10-32 to 1-1/2 NPT.
Straight Through Mufflers use an internal sleeve of sound reducing foam, with threads from ¼ NPT to ¾ NPT, with male threads on one end and female threads on the other.
Heavy Duty Mufflers have an aluminum shell and an internal stainless steel screen that keeps contaminants like rust from being ejected in a dangerous way.  We have them in ¼ NPT and ¾ NPT sizes.

Shutoff and Solenoid Valves

Another one of our Six Steps To Optimizing Your Compressed Air System is to turn off the compressed air when it’s not in use. For this, EXAIR offers manual ball valves, for operator control, and Solenoid Valves, to automate the process.

Solenoid Valves (left) are available for 120VAC, 240VAC, and 24VDC in sizes from 1/4 NPT to 1 NPT. We offer manual Ball Valves in sizes from 1/8 NPT to 1-1/4 NPT.

Swivel Fittings, Stay Set Hoses, and Magnetic Bases

EXAIR Super Air Nozzles are threaded for installation with common air pipe & hose fittings. If the pipe isn’t pointed in the exact right direction, a Swivel Fitting gives you 50°  of adjustability. If the pipe isn’t quite close enough to what you want to blow off, Stay Set Hoses come in lengths of 6″ to 36″, and when bent to aim the Air Nozzle, they ‘stay set’, as advertised, until they need to be moved. If a pipe doesn’t exist and you need to run an air hose from the nearest drop on the header, Magnetic Bases can support the Air Nozzle and a Stay Set Hose to get the air where you want it. They even have shutoff valves to turn them off when they’re not in use (that’s a good thing; see above).

Save installation time AND get your blowoff pointed in the right direction!

Hoses and Compressed Air Fittings

If you need one of the aforementioned air hoses to reach a Magnetic Base or to supply a Safety Air Gun, we have two diameters to choose from – 3/8″ ID (1/4 MNPT threads on the ends) and 1/2″ ID (1/2 MNPT threads on the end), and we can make them to any length you need. And, while our selection probably isn’t quite as comprehensive as your local piping supply shop, we stock a number of pipe nipples, Couplers, Reducers, Tees, and Elbows that are commonly used with our products. So – like my backup sump pump deluxe kit, we can put all the fittings you may require in the same box for you.

Contact an Application Engineer if you have ANY questions about how to properly supply compressed air to your EXAIR products.

At EXAIR, we’re here to make sure you get the most out of our products, and your compressed air system. If you need accessories to help with that, give me a call.

More Benefits Than Being Adjustable

Years ago I was working with a pet food manufacturer who was having issues with their bag opening machine. The problem they had with their existing setup was the dust from manufacturing processes would get sucked into the venturi and start to decrease their performance. Hence, they needed a better solution that wouldn’t need to be replaced and could be cleaned.

Adjustable E-Vac

The bags were empty, and this vacuum generator was positioned to pull the bag open. The bags were made of a non-porous material as they had a coating on them and thus the actual action of opening the bag was not difficult. Enter dust through the throat of a small venturi, and it caused several downtimes that were not scheduled. When looking at the performance characteristics of their existing system I crossed that over to an EXAIR model 840008M – Adjustable E-Vac w/ Straight Through Muffler. This unit was able to open the bag and hold it open for their machine needs. The throat passage of the unit was also larger than their existing generator and the biggest benefit, the Adjustable E-Vac could easily be taken apart and cleaned. To see how easy they are adjusted, which is the same method used to take them apart, check out this previous video blog linked in the image below.

The process changed from changing an existing vacuum generator out, scrapping the old one, and putting in a new one to keeping two on hand. One (EXAIR Adjustable E-vac) that is in operation and functioning, then after a designated amount of time (predictive maintenance), they change it out for the spare (EXAIR Adjustable E-vac) vacuum generator. The second part of the process involves breaking the used one down (without the need for any specialized tools), to clean each of the three pieces on the unit. The refurbished unit is then reassembled, benchmarked for performance, and put on the shelf for the next maintenance cycle.

While this system uses the same volume of compressed air as their previous solution, we still save money in the amount of unusable replacements they were ordering with repairable units, allowing them to keep a working spare on hand. So it saves the customer money on the life of the product. A further benefit is the customer can also get the EXAIR Adjustable E-Vacs quickly as they are standard stock item for us at EXAIR and can ship the same day on orders received by 2 PM ET.

If you want to discuss how an Adjustable E Vac makes sense for you and your team, contact an Application Engineer today!

All the Hoses, Tubing, and Accessories Necessary for Your Intelligent Compressed Air Products®

In order to make sure you’re able to get the most out of your Intelligent Compressed Air Products from EXAIR, we offer a wide variety of various hoses and tubing to complement several of our product lines.

For any Line Vac Pneumatic Conveyor application, you may need appropriate tubing to handle the intake and outlet flow of the conveyor. EXAIR offers a clear reinforced PVC hose from stock in sizes ranging from 3/8” to 3” ID for use with our smooth Aluminum, Stainless Steel, and Heavy Duty Line Vacs. The PVC hose is available in lengths up to 50’ in 10’ increments and is on the shelf ready to ship, alongside the Line Vacs themselves. The hose is very flexible with a smooth internal bore that eliminates material build up. The reinforced, heavy wall of the clear hose provides visual confirmation that the material is moving when compressed air is supplied to the Line Vac. These hoses are rated for use in temperatures ranging from -4 to 150°F (-20 to 66°C).

 To help supply air to your Safety Air Guns, we offer (3) different styles of 12’ (3.6m) coiled hoses to help keep the area free of tangled air lines. Sizes are available in 1/8 NPT x ¼” ID, ¼ NPT x 3/8” ID, and 3/8 NPT x 3/8” ID. Each coiled hose has swivel fittings installed on either end for ease of installation.

If you need a bit longer length to supply your point-of-use products, or need a larger diameter hose, we also have both 3/8” and ½” ID compressed air hoses. These are manufactured with a reinforced synthetic rubber to assure long life and protection against ozone, weathering, and temperatures up to 158°F (70°C). Hose lengths are available in 10’, 15’, 20’, 30’, 40’, and 50’.

For EXAIR’s E-Vac Vacuum Generators, polyurethane vacuum tubing (along with various push-in fittings) is available to help connect to the necessary vacuum cups. The tubing comes in either ¼” ID or 3/8” ID in lengths ranging from 10’ to 50’. This allows you to build up a complete vacuum system when including the mufflers, vacuum cups, and generator itself!

All of these options are available from stock to ship alongside any Intelligent Compressed Air Product. If you need help determining the proper hose sizes based on your point-of-use products get in contact with an Application Engineer today for help!

EXAIR E-Vac Vacuum Generator Accessories: Overview

Vacuum systems are becoming more and more prevalent within manufacturing day by day. Vacuum powered lifts can make it easy to lift and move small objects like tiny coins to heavy steel plates. Vacuum chucks hold work pieces that could be marred by jaws or vises. And sealed vessels can be pressure tested or tested for leaks by pulling a vacuum on them. It’s pretty simple to pick out which vacuum generator that you need, but what about the accessories? There are so many different accessories to choose from such as mufflers, suction cups, hose, valves, and connections. The following is a quick overview of the different accessories that you can get from EXAIR along with your E-Vac vacuum generator.

Vacuum cups for E-Vac generators

Suction cups are a very common accessory that you need when using a vacuum system. Vacuum cups allow one to create a seal on the surface of the object that you wish to pick up and is what allows the system to lift objects. 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 an uneven surface.

EXAIR’s Standard and Straight Through Muffler

Next up is the mufflers; they muffle the sound generated by the E-Vac and quiet a working vacuum generator. There are two different types of mufflers from EXAIR 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.
