EXAIR Accessories – We’ve Got you Covered

When you work with us here at EXAIR, we strive to have all the ancillary items that you might need to make your installation a success, without having to find components at the last minute or perhaps using the wrong sized components. Each specific product line such as Super Air Knives or Line Vac air operated conveyors have specific accessories such as mounting brackets or plumbing kits which EXAIR has made to simplify the installation of those particular products. We also carry generalized accessories which work across all of the product lines so you do not have to use multiple vendors or purchase orders.

Silencing Mufflers – Per OSHA Standard 1910.95(a), a worker must not be exposed to sounds levels above 90 dBA for any eight hour shift of a 40 hour work week.  EXAIR offers several types of mufflers including – Reclassifying, Sintered Bronze, Straight-Through and Heavy Duty.  For reducing the noise associated with an EXAIR E-Vac Generator, Vortex Tube, Cabinet Cooler System, or the exhaust air from cylinders, valves and other air powered equipment, we’ve got a muffler that will help to keep the noise level at an acceptable level.

Mufflers

Solenoid and Manual Valves – The easiest way to reduce compressed air usage and save on operating expense is to turn off the compressed air to a device when it isn’t needed. EXAIR carries a wide assortment of solenoid valves, with offerings in the NEMA 4/4X classification, and supply voltages of 24VDC, 120VAC, and 240VAC.  We also have manual ball valves from 1/4 NPT to 1-1/4 NPT and a foot operated valve, with 1/4 NPT connections.

Valves

Swivel Fittings, Stay Set Hoses and Magnetic Bases – To provide a great degree of flexibility for positioning an EXAIR Super Air Nozzle, Air Jets or Air Amplifiers, EXAIR offers several items.  The Swivel Fittings have 25 degree of movement from the center axis, providing a total of 50 degree of adjustability.  The position is locked in place and holds until adjustment is needed. For applications where frequent re-positioning of the air device is required, the Stay Set Hoses are ideal.  Simply mount the hose close to the application, bend it to the shape preferred, and because the hose has “memory”, it will not creep or bend.  Lastly, the Magnetic Bases are another option for flexible, movable installations.  The base has a on/off valve, and a powerful magnet to hold in any vertical or horizontal mounting arrangement.

Hoses – EXAIR can provide hoses for your application.  For the Line Vac air operated conveyor applications, we offer conveyance hose – a durable, clear reinforced PVC hose, in diameters of 3/8″ to 3″ ID, and lengths up to 50′. On the compressed air side, we can provide 12′ Coiled Hoses with 1/8, 1/4, and 3/8 NPT connections, and also 3/8″ and 1/2″ ID hose in lengths to 50′.

Hoses

Filter Separators, Oil Removal Filters and Pressure Regulators – Perhaps the most important accessories for use on a compressed air device are filters and regulators. Filtering the compressed air of dirt, debris, moisture and oil will help to prevent build up inside the EXAIR products, leading to longer service life, and less time spent cleaning, while providing optimum performance. Regulating the air pressure allows for tuning of the performance, using the proper amount of compressed air to obtain satisfactory results.

Filter and Regualtors

EXAIR Has Solutions For Skin Problems (Really)

The EXAIR Chip Trapper filters solid debris from your coolant that can not only clog the supply lines to the tooling, but also provide a LOT of surface area for the growth of bacteria. This can really foul the air in a machine shop, and sometimes, it can mess with your skin, causing a rash or infection. Honestly, this isn’t a HUGE problem…I’ve fielded a handful of calls about it over the years, though, so when I got the call from a machinist last week who wanted to talk about a possible solution for a skin problem, I immediately thought of the Chip Trapper.

Well, immediately after I thought about this old commercial (I’ve written before about how I watched way too much television growing up. Don’t judge.)

Turns out, though, his problem wasn’t bacterial – it was an allergic reaction he was having with a specific additive in the coolant used on a particular machine tool. He mentioned that it was a mist coolant application, so I immediately thought of the Cold Gun Aircoolant System.

Of, course, right after I thought about this commercial (seriously; stop judging.)

To my knowledge, it’s the first time we’ve ever applied a Cold Gun to solve a skin problem – we’re almost always looking at them to avoid the mess of coolant spray, or to increase tool life in situations where traditional machine tool coolant is impractical (or impossible) to use.

With four distinct models to choose from, we've got a Cold Gun System to meet your needs.

If you’d like to find out how EXAIR products can save you from:

*Excessive compressed air consumption
*High sound levels
*Static charge problems
*Heat damage to your electronics
*Labor intensive “bucket and ladder” bulk conveyance operations
*Trips to the dermatologist (no, really)

Then give me a call.  We can even talk about vintage TV commercials (I won’t judge either.)

Save Money By Using Your Own Thermostat? Well…

Last week, I wrote about what a great idea it is to use a thermostat with a Cabinet Cooler System. I’ll let another cat out of the bag right now and tell you that there are less expensive thermostats than ours. But just like the savings you might realize on the purchase by foregoing a thermostat, using a poorly specified thermostat can also be the last savings you see.

In a Cabinet Cooler System application, we’re refrigerating air. This makes for a cool, clean, and dry atmosphere for your electrical & electronic components to operate in.

UL Listed & CE Compliant, EXAIR Cabinet Cooler Systems maintain NEMA 4, 4X, or 12 integrity.
UL Listed & CE Compliant, EXAIR Cabinet Cooler Systems maintain NEMA 4, 4X, or 12 integrity.

Not all thermostats are designed to read air temperature – in fact, a LOT of common, commercially available thermostats are designed for use with liquid. Using these to control air temperature will lead to slow response times. That means one of two things will happen:

When the air inside the enclosure is cooled to the thermostat’s set-point temperature, it won’t shut off the compressed air flow to the Cabinet Cooler unit, resulting in unnecessary compressed air consumption.  And that’s a shame.

OR:

When the air inside the enclosure is heated to the thermostat’s set-point temperature, it won’t start the compressed air flow to the Cabinet Cooler unit, resulting in a potential overheating of those expensive…or critical…or both…electronic components.  And that’s a REAL shame.

We don’t want to see you using any more compressed air than you need to.  And we SERIOUSLY don’t want to see you fry your electronics.  If you’d like to find out more about EXAIR Cabinet Cooler Systems, give me a call.

Save Money By Not Using A Thermostat? Well…

I’m going to let the cat out of the bag right now and tell you that a Cabinet Cooler System with Thermostat Control costs more to purchase than one without.  So yes, by passing on the Thermostat Control, you WILL save money on the purchase.  But that may be your ONLY realization of any money saved.  Let’s consider:

Recently, a customer submitted a Cabinet Cooler Sizing Guide – our simple guide for gathering key pieces of information about the state of customer’s enclosures. An EXAIR Application Engineer can quickly & accurately calculate the actual heat load of an electrical enclosure, and specify the appropriate Cabinet Cooler System, when given the information.

You can submit your data via email or fax, or you can call an EXAIR Application Engineer for immediate assistance.
You can submit your data via email or fax, or you can call an EXAIR Application Engineer for immediate assistance.

I calculated the total heat load of their enclosure to be 2,200 Btu/hr, so I specified a Model 4340 NEMA 12 Cabinet Cooler System rated for 2,800 Btu/hr, with Thermostat Control.  At this point, we’re occasionally asked about the down-side of not using a Thermostat.

The calculated heat load of 2,200 Btu/hr is 78.5% of the Model 4340’s 2,800 Btu/hr cooling capacity.  That means, theoretically, the Thermostat Control will turn off the compressed air supply 21.5% of the time:

40 SCF x 60 min x 8 hr x 5 days x 52 weeks x 21.50% = 1,073,280 SCF
min hr day week year year

At EXAIR, we know, first hand, the benefit of saving a million Standard Cubic Feet of compressed air.  We use a general thumbrule which holds that 1,000 SCF of compressed air costs $0.25 to generate.  So here it is, in dollars and cents:

1,073,280 SCF x $0.25 = $268.32 annual savings
year 1,000 SCF

In this example, the Thermostat Control will pay for itself within the first year.

Summer is approaching in the Northern Hemisphere.  If you’d like to find out more about how EXAIR Cabinet Cooler Systems can protect your electrical and electronic components from heat damage, give me a call.

Keeping the Confusion Out of NPT Pipe Thread Dimensions

I recently had the pleasure of helping a caller solve a problem with a Super Air Nozzle.  He had measured the opening on the outlet of his air gun, and ordered accordingly…unfortunately, he didn’t know that 3/8 NPT did NOT correspond to a 3/8″ diameter of a threaded fitting.  I explained the reason for this, a while back, in a blog entitled “When Is A Half Inch Not A Half Inch? When It’s Half Inch Pipe, Of Course!

The ID of a 1/8 NPT threaded fitting is actually pretty close to 3/8". Here's a dimensions table that I reference often.
The ID of a 1/8 NPT threaded fitting is actually pretty close to 3/8″ (left.) Here’s a link to a dimensions table that I reference often to keep this (on right, a 3/8 NPT nozzle with an 1/8 NPT air gun) from happening.

 

As you can see, the Model 1105 3/8 NPT Super Air Nozzle will not fit the 0.405″ (not far at all from 3/8″ if measured with a ruler) ID of a 1/8 NPT threaded connection.  No matter; these are all catalog parts that we have plenty of stock on, so, after a brief discussion of pipe thread sizes, he got a Model 1103 1/8 NPT Super Air Nozzle, and it fits just fine:

IMG_5789

Sometimes, an adapter is required for air guns that have straight threads.  Two common sizes for these are 5/8″-28 and 3/4″-32 – and we have adapters for both of these (call for details.) Other adapters are readily commercially available…you may find them in the plumbing aisle of your hardware store, or from a local pipe & pipe fitting supplier.  We’ve seen some air guns, though, that have a proprietary thread that doesn’t match up to anything else…in these cases, we have four types of Safety Air Guns on the shelf, ready to ship.

If you’d like to find out more about using quiet and efficient engineered Super Air Nozzles for your air gun applications, give me a call.

Here We Go Again, Making Your Life Easier

If you’ve seen our latest E-NEWS, you know what I’m talking about. If you don’t get our E-NEWS (and you’re reading this blog on purpose,) you should…sign up here:

This is all it takes to subscribe to our E-NEWS.
This is all it takes to subscribe to our E-NEWS.

But I’ll tell you what the “headline story” is about anyway, right now. EXAIR has been making Air Knives for about 30 years now, and if the front covers of our catalogs for at least the last 6 years mean anything, the Super Air Knife is our unofficial “flagship product.” It IS the most efficient and quietest blow off product on the market, as well as the most versatile. They come in lengths from 3″ to 108″, and can be coupled together for much longer uninterrupted curtains of high velocity laminar air flow. You can regulate the pressure supply to produce however strong, or light, of an air flow that you need to solve your application. We make them in aluminum, 303SS, 316SS, and even PVDF for whatever environment you may need to expose them to. And they’re all in stock, available for immediate shipment. We even have a variety of useful accessories to help you get the most out of our Air Knives…making them easy to install, position (or reposition,) plumb, operate, etc.

EXAIR has a comprehensive line of beneficial accessories for our Engineered Compressed Air Products.
EXAIR has a comprehensive line of beneficial accessories for our Engineered Compressed Air Products.

We didn’t start off with all this, back in the 1980’s, though. Some of them were developed by our Engineering folks (Design AND Applications) based on our collective experience and knowledge, and they’ve proven to be valuable additions to the product line. I’m proud to be a part of this team…after all it was one of my heroes, Henry Ford, who said “If I’d asked people what they wanted, they’d have said ‘faster horses.'”

Not that we discount the value of what users want…we actually keep a running list, informally called the “Can’t Do It List,” on which we record inquiries for product applications that we don’t have a solution for…yet.  We meet and review this list twice a month, so it’s always on the “front burner,” so to speak.

I won’t lie; not everything that goes on that list makes it into our catalog. Nor does everything proposed organically by Engineering folks here. But when it does, it’s kind of a big deal to us, and we get excited. Like the introduction of the Stainless Steel Plumbing Kits for our Stainless Steel Air Knives that are the highlight (again, for the Engineering folks here anyway) of the latest E-NEWS. Which I hope you’ve subscribed to by now. If you haven’t, go ahead…I’ll wait.

But seriously, I hope you do take advantage of our E-NEWS as a way to keep on top of the latest developments in compressed air product technology from EXAIR. And if you ever want to talk about an application or a particular product, give me a call. If we’ve got something, that’s great. If not, maybe you’ll see it in an upcoming E-NEWS. I promise that you’ll find that just as cool as we do.
