How to Install A Super Air Knife – From the Basic to the Creative

Occasionally, a caller will ask if we offer installation services for our products. They’re usually very pleased to learn that there’s not all that much to it.

Any of our Super Air Knives can use our Model 9060 Universal Air Knife Mounting Systems (shown below; one on a 12″, and four on a 108″ length) for easy installation and precise aiming.

The 9060 Universal Air Knife Mounting Systems are perfect for simple, fast installation and positioning.

Shorter lengths, like the Model 110006 6″ Aluminum Super Air Knife (below, left,) can be adequately supported by air supply piping.  We don’t recommend that with longer lengths (due to overhung load concerns) but even a Model 110018 18″ Aluminum Super Air Knife (below, middle,) can be supported by the supply pipe in a vertical position.  We even stock our 3″ Aluminum Super Air Knives with Stay Set Hoses & Magnetic Bases (below, right.)

Just a few more popular ways to install a Super Air Knife.

The Super Air Knife also has a series of 1/4″-20 tapped holes, 2″ apart, along the bottom of the body.  These are often used for installation & mounting as well, and we’ve seen some creative methods, for sure:

Yes, that’s a door hinge. No, it wasn’t my idea, but I kind of wish it was.

EXAIR Super Air Knives come in lengths from 3 inches to 9 feet long.  We stock them in aluminum, 303SS, 316SS, and PVDF.  If you need a custom length or material, though, we do those too.  We can even talk about the best way to mount it.  Call me.

Accessories and the Value Added

The word “accessory” can come with some baggage… it’s become synonymous with “add-on” and “up-sell,” and cost-mindful consumers may see them as just another way for a slick salesperson to make an extra buck. And frankly, they wouldn’t have that reputation if there wasn’t some truth to it.  The server at your favorite restaurant will offer appetizers, or recommend side dishes to go with your entree. If you go to buy a new car, you’ll get a pitch for a variety of aftermarket add-ons.  The paint counter folks at the hardware store always tell me what specific brush and/or rollers I should use with the paint I’m buying…and it’s never the 10-pack of economy brushes that costs less than the single, premium quality brush they recommend.  In all of these cases, these employees are trained, constantly encouraged, and hopefully rewarded on the success of these “up-sell” strategies.

Of course, my boys and I can devour even the largest plate of chili cheese nachos long before the rest of meal comes out.  My wife absolutely loves the remote starter function that the dealership installed on the new car she bought last year.  And, if you’ve ever painted a well-lit room, you know the difference between a $1 paint brush and a $10 paint brush.  So if my server gets a little bigger tip, my car dealer salesperson gets a little more commission, or the paint counter folks get a bonus, then it’s a win-win, as far as I’m concerned.

EXAIR carries a variety of accessories for our Intelligent Compressed Air Products.  Some aid in mounting & installation:

Clockwise from top: Universal Air Knife Mounting System, Stay Set Hoses, Cabinet Cooler Side Mount Kit, Mounting Brackets for Line Vac, Filter Separator, and Pressure Regulator, Swivel Fitting for Super Air Nozzle, Tool Holder for Industrial Vacuum Drums, Spray Nozzle Mounting Clip.

Others make it easy to ensure adequate supply conditions:

The performance of many EXAIR Intelligent Compressed Air Products can be altered by replacing the shim:

From left to right: Super Air Amplifier, Super Air Knife, 1″ Flat Super Air Nozzle, High Velocity Air Jets, and Air Wipe all feature replaceable shims to modify performance.

In addition to these product-specific accessories, EXAIR carries a complete line of:

Filter Separators are rated for air flow up to 400 SCFM; Oil Removal Filters, up to 310 SCFM.

*Filter Separators to remove water, dirt, and rust from your compressed air system.  Our Automatic Drain Filter Separators have a 5 micron particulate element, and a centrifugal vane to remove moisture.

*Oil Removal Filters with coalescing elements that remove any trace of oil, and also provide additional particulate filtration to 0.03 microns.

 

*Pressure Regulators, so you can “dial in” the performance you need, so you don’t overpower the application, or waste compressed air.  They come in sizes from 1/4 NPT to 1-1/4 NPT, and are rated for flows up to 700 SCFM.  A pressure gauge provides accurate indication of outlet pressure, and the adjustment cap can be removed to prevent tampering.

*Mounting Brackets and Modular Coupling Kits for our Filters and Regulators.  The latter are especially handy for easy, compact, and leak free installation.

*Silencing Mufflers to reduce work area noise from compressed air exhausting from pneumatic cylinders, valves, etc.  There are several styles to choose from, depending on your needs:

  • Sintered Bronze Mufflers are simple in design, with minimal back pressure restriction, and come in sizes from #10-32 thread to 1-1/2 NPT.
  • Straight-Through Mufflers offer noise reduction up to 20 dB, and come in sizes from 1/4 NPT (up to 22 SCFM) to 3/4 NPT (up to 73 SCFM.)
  • Heavy Duty Mufflers have an internal stainless steel screen that not only protects the exhausting components from environmental contamination, but also keeps air system contaminants from being ejected at high speed into the work area.
  • Reclassifying Mufflers are an upgrade to the Sintered Bronze Mufflers and provide the highest level of noise reduction – up to 35 dB.  They also trap oil mist, eliminating breathing hazards to personnel.

*We have manual ball valves (1/4 NPT to 1-1/4 NPT) and Solenoid Valves (120VAC, 240VAC or 24VDC) from 1/4 NPT to 1 NPT, and a Foot Valve, for hands-free operation.

*Swivel Fittings to securely install & aim many of our nozzles, from the Atto to the High Force 1 NPT Super Air Nozzles.  For a little more flexibility, Stay Set Hoses and Magnetic Bases can be used for Air Amplifiers, Super Air Nozzles, and even short Air Knives.

*12 ft Coiled Hoses (1/4″ or 3/8″ ID) and Compressed Air Hose (3/8″ or 1/2″ ID; up to 50ft lengths) can be provided with any Intelligent Compressed Air Product.  We also have a full supply of fittings (tees, elbows, nipples, couplers, reducers, etc.) and adapters to fit our Super Air Nozzles to your existing air guns or blow off devices.

*Receiver Tanks are used to store a ready supply of compressed air.  If you have an intermittent demand of sufficient size, it can cause a pressure transient in your system, which can drag down the ability to supply other points of use.  Installed near the point of intermittent demand, they prevent pressure & volume fluctuations, keeping the operators at all points of use happy.  Model 9500-60 Receiver Tank has a capacity of 60 gallons, is rated to 200psig, and meets ASME pressure vessel code.

In closing, let me offer the following advice that’s served me well over the years:

*Be mindful of the valued added by the accessories & add-ons you’re presented during a purchase of capital equipment…or anything else, really.  Don’t buy something you don’t need, but if you need it…well…it’s OK to buy it.

*Don’t skimp on quality.  Odds are, if an accessory is offered by the manufacturer of the product, it’s going to work well for you.  They should be able to tell you if it will or won’t if you discuss your needs with them.  I know I will if you call me to discuss a compressed air product application.

*Get the big plate of nachos, especially if you’re dining with teenagers.

The Super Air Knife: It’s Super Easy To Install

One of the more commonly asked questions about one of our more commonly asked-about products is:

“How do you install a Super Air Knife?”

Well, I’m glad you (or, in this case, “they,”) asked! There are several options, and they’re all pretty simple:

The Universal Air Knife Mounting System – right out of the box, the 9060 Universal Air Knife Mounting System is ready to go. It gives you a complete range of motion, so changes to the angle, direction, and distance of the air flow to the target are quick and easy. Multiple systems provide secure support for longer Air Knife lengths.

The 9060 Universal Air Knife Mounting Systems are perfect for simple, fast installation and positioning.

The Air Knife Plumbing Kit – Air Knives 24″ and longer need to be supplied at multiple inlets.  A Plumbing Kit comes with everything you need to get that down to just one (lengths to 54″) or two (lengths to 108″) 1/2 NPT connections, saving you from hunting down the fittings and hose or tube, while ensuring you get sufficient air flow for optimum performance.

Plumbing Kits

The Super Air Knife Itself (part 1) – because the Air Knife cap & body are held together with a series of Stainless Steel cap screws, there’s a 1/4″-20 tapped hole, about 3/8″ deep, every 2″ along the bottom of the body. These are commonly used to install the Air Knife to an acceptable mount.

If you've got something to hold it to, mounting a Super Air Knife with 1/4"-20 fasteners is a snap!
If your equipment already has rails or a frame, mounting a Super Air Knife with 1/4″-20 fasteners is a snap!

The Super Air Knife Itself (part 2) – like I said above, when they get longer than 24″, an Air Knife needs to be supplied at both ends to ensure proper air flow across the entire length. There are MANY Super Air Knives installed over conveyor belts (a “textbook” application) that are simply supported by hard piping to both ends. The Air Knife is, essentially, as well supported as the piping.

The Super Air Knife Itself (part 3) – I saved “part 3″ to talk about the 3” Super Air Knife specifically…see what I did there? These short, compact units can actually be supported and plumbed properly, using a Magnetic Base and a Stay Set Hose.
