Just My Size

Published on by exaircorpLeave a comment

So, I was spending some daddy/son time with my 5 year old this past weekend, (5 and a HALF if you ask him), when he asked me about my new job and what kind of “stuff” I helped our customers with. So we got on our tablet and I showed him our website, EXAIR.com. I decided to start off with our Super Air Nozzles because I thought he might be able to relate a little after seeing me use my portable compressor to blow off my workbench, sawdust, etc. in our garage.

As we scrolled through the section we came upon our Atto Super Air Nozzles. Well, that was the ONE for him! He was so excited that we had nozzles that were, per his words, “just my size” and he wanted to know when I was going to bring him one home.

Of course, as with most children, I could see his wheels turning as he was trying to come up with ways that he could use these to push his cars around or blow the dirt out of his Power Wheels dune buggy or maybe just blow some air at our dog, you know, just for fun. (By no means would I condone this behavior.)

Since we offer the Atto Super Air Nozzle in both 316SS and PEEK material, I asked him which one he thought he would want…… BIG decision for a 5 year old! (Well, 5 and a HALF). Of course the answer was, “just get me both daddy because they are little, just my size”.

Take a look at our extensive Super Air Nozzle selection.  The fact is that we fit any “size” from 4x.05 metric to 1-1/4″ NPT and almost every size in between, as well as multiple material options.   No matter what your applications size, or environment, chances are we will have a Super Air Nozzle that will fit it, if not then we have twelve other product lines that might just fit the need.  Feel free to check the website, EXAIR.com, and check out our Super Air Nozzles. I can guarantee there will be something to fit your application, or “just your size”, if not we’ll take it back under our 30 day guarantee.

OSHA Compliance? We Got That.

Published on by Russ BowmanLeave a comment

OSHA Standard # 1910.242(b)

Compressed air used for cleaning. Compressed air shall not be used for cleaning purposes except where reduced to less than 30 p.s.i. and then only with effective chip guarding and personal protective equipment.

We get calls on a regular basis from folks, looking for products that will provide an effective flow of air for cleaning, blow off, drying, etc., but with the supply pressure turned down to less than 30psig, like OSHA requires. When you limit yourself to that low of a supply pressure, though, you’re simply not going to get the volume flow rate or air flow velocity to be successful.

You don’t have to limit yourself to that pressure at all, however…they’ve also published documentation that further explains that this limit applies to the “nozzle pressure,” or, the static pressure that would exist due to the dynamic flow, if dead-ending were to occur.  That means that if the nozzle’s outlet(s) were completely obstructed (dead-ended), the static pressure, if it were greater than 30psig, would be great enough to break the skin and cause a grave and potentially life-threatening condition, known as an air embolism. Of course, if the nozzle’s outlet(s) can’t be completely obstructed, then the static pressure realized at whatever portion IS obstructed will be much lower, and therefore, safe & compliant.

Untitled This is where EXAIR’s Super Air Nozzles “earn their stripes” – by design, they cannot be dead-ended. It’s not the ONLY design that can’t be dead-ended, but it IS the most efficient …we’ve tested a good many of the others in our Efficiency Lab, and have proved this time after time.

Speaking of OSHA compliance, most of our Super Air Nozzles also meets OSHA’s standard 1910.95(a) for Maximum Allowable Noise Exposure. Only our largest ones (3/4” NPT and up) exceed the 90 dBA limit for 8 hour continuous exposure, so hearing protection is necessary, but they’re still considerably quieter than the same sized open-end pipe blow off. OSHA Noise Level Back to that last part of 1910.242(b); the part about effective chip guarding: EXAIR’s Precision, Soft Grip, and Heavy Duty Safety Air Guns are all available with clear polycarbonate Chip Shields. They’re all in stock, available for same-day shipment; same as any other EXAIR catalog product. 1210-6cs If you’d like to know more about how EXAIR products can help you achieve OSHA compliance in regard to your use of compressed air, give us a call. We’re eager to help!

Award Winning Compressed Air Nozzle Saves Hundreds of Dollars Annually

Published on by Dave WoernerLeave a comment

EXAIR’s 1 Inch Flat Super Air Nozzle won the Gold Award for Compressed Air from Plant Engineering in 2014. We won the award for the immense savings that our customers reap by using this nozzle to replace open blow offs. While saving compressed air, we also reduce noise level and comply with an OSHA regulation 192.242(b).  Do not leave that blow off open. It is costing you everyday in dollars; it may cost you more in OSHA fines later, and it will cost your employees hearing later.

A 1/4″ copper tube can use 33 SCFM at 80 PSIG of inlet pressure. This homemade blow off will use 1,980 standard cubic feet per hour. Typical industrial compressed air cost $0.25 per 1,000 standard cubic feet.  That 1/4 copper tube is costing you $0.50 every hour to run. Each year, one 1/4″ copper tube costs $2,970*.

The 1 inch Flat Super Air Nozzle, model 1126, uses 10.5 SCFM or 22.5 SCFM less than 1/4″ Copper tube.  Saving your company 22.5 SCFM, is the same as saving $0.34 every hour or $2,025 every year.*  Saving 22.5 SCFM also, means that your compressor system doesn’t have to work as hard.  A 5 HP compressor will put out 20 SCFM, so replacing one 1/4″ Copper Tube with a model 1126 will save you from upgrading compressor system as your company expands.

Regardless of the $2,025 you just saved by replacing the homemade blow offs with engineered nozzle, it is also an industry best practice because it can lower the noise exposure for personnel and prevent any harm from dead end pressure.  OSHA standard 29 CFR – 1910.95(a) requires that if an employee is exposed to greater than 100 dBA for 2 hours, he or she needs to wear hearing protection.  A 1/4″ copper tube will easily exceed 100 dBA.  The model 1126 will lower the noise level to 77 decibel, 13 dBA lower than the OSHA requirements for an 8 hour day.

Finally, the 1″ Flat Super Air Nozzle cannot be dead ended, which protects your employees from serious injury. In the event, that a compressed air orifice is blocked with no means of escape, air may enter the bloodstream from an open cut or wound in the skin. Compressed air must be kept below 30 PSIG to eliminate this danger when using an open pipe, tube or many commercial air nozzles. With EXAIR nozzles, pressure to the nozzle  can remain at line pressure and produce the maximum velocity and force for a successful application.

Adapting To The Situation At Hand

Published on by Brian FarnoLeave a comment

Earlier this week I received a call from a customer who had an issue in his facility with the hand held blow guns the operators were using.   The units he had were simply too loud and he was trying to get below the 85 dBA threshold for hearing protection.  Not to mention they were using a large volume of compressed air.

I discussed the application with the customer only to discover they are blowing dry aluminum chips off a table and need a three foot extension so the operators can easily reach all extents.   The nozzles they had on their existing blow guns were essentially a cross drilled “safety nozzle”.  The customer was using the same model air gun throughout his facility at a total of 33 machining centers.   Each unit had a gun with a 3′ extension and a cross drilled nozzle like tip.

After discussing the amount of chips and what they were using I recommended he utilize a newer style adapter we have that would appear to work on his existing gun with the existing extension.  This means, rather than having to replace the entire air gun, extension pipe, and nozzle, he was able to purchase a simple adapter along with our model 1100 Super Air Nozzle and retrofit his entire facility.  This cut the budget needed by more than half of other solutions he was looking into from other companies.   Picture of the nozzle and adapter are below.

This was just another adapter for EXAIR but it was the right adapter for the customers existing product.  So if you have an existing blow off and you don’t want to replace the entire blow off device but you want to try and upgrade your system, contact us.
