How Much Money Will You Save with Engineered Air Nozzles

The simplicity of installing an air nozzle and the importance of saving compressed air (which in turn saves money) go hand-in-hand with our engineered air nozzle product line. For an 8 hour shift running 250 days per year, replacing one 1/4″ open air tube can save $650 dollars per year. Replacing any run-of-the-mill, commercial air nozzle can typically save $330 dollars per year!

How many open tubes or commercial air nozzles do you have?
10 tube replacements = $6500 saved per year
25 tube replacements = $16,250 saved per year
50 tube replacements = $32,500 saved per year                          

10 commercial nozzle replacements = $3300 saved per year
25 commercial nozzle replacements = $8250 saved per year
50 commercial nozzle replacements = $$16,500 saved per year

Greeting Cards saved by 1″ Flat Super Air Nozzle

A greeting card manufacturer used a liquid coolant plastic nozzle to provide an air assist to divert greeting cards to an auxiliary straight conveyor. Without the air assist the cards would bounce and fly from the conveyor leading to a loss of products and more maintenance.  They used what they had on hand which was a coolant nozzle pictured below.

Coolant Type Nozzle
Liquid Coolant Nozzle uses 32 SCFM at 40 PSIG and 57 SCFM at 80 PSIG.

This nozzle was run at a fairly low pressure of 10 PSIG, but still used 7.8 SCFM at 10 PSIG.  The nozzle worked well, but if run for 24 hours over 250 working days, it costs $702 to supply air to the nozzle. The customer utilized (40) nozzles in their plant which cost them $28,080.  Also, the nozzles were incredibly noisy, since they were designed for liquid flow.

Our customer decided to upgrade to an engineered air nozzle after some time. They needed to cut their air consumption, but still get the job done.  They tested our 1″ Flat Nozzle, but with the standard 0.015” shim it used 5.7 SCFM of compressed air at 10 PSIG. This would be a savings, but after a quick conversation with our Application Engineers, the customer decided to install a 1″ Flat Super Air Nozzle with only a 0.005″ shim. This nozzle 1126-.005 only used 0.9 SCFM of compressed air at 10 PSIG of inlet pressure.  Replace their 40 liquid coolant nozzle would save them 6.9 SCFM per nozzle. 276 SCFM if all 40 nozzles were replaced. Saving 276 SCFM lowered energy bill for their air compressor by $24,840 anuually. Which would mean the simple ROI for $41, 1″ Flat Super Air Nozzle would be 17 days!

Using Water and Air to Clean or Cool Cylindrical Parts

In the last year EXAIR has released two products that aid in cleaning and cooling cylindrical shapes. The liquid sprayed from our AT1010SS Internal Mix Spray Nozzle creates a 360° Hollow Circular Pattern that is excellent for cleaning the inner diameter of a pipe, a casting, or a bore. The 1006SS Back Blow Nozzle is an air only nozzle that is designed to clean, dry or cool the inside diameter of a hose or tube and also effective cleaning out channel. These products can be used in conjunction to create a more powerful system than either component by itself.

360 degree Internal Mix Hollow Circular Pattern
AT1010SS – 360° Internal Mix Hollow Circular Pattern

The AT1010SS spray nozzle can be used in a variety of applications. As I mentioned above the 360° spray pattern is great for spraying out the inside of a pipe or duct-work. In addition to these applications, the nozzle can be used to cover a wide area with spray patterns up to 53 inches in diameter. This wide spray area can be used for humidification, dust suppression, cooling or sanitizing. The 303 stainless steel construction of the nozzle will hold up to a variety of chemicals and environments.  These nozzles can cover a significant area while using a relatively small amount of air and liquid. The AT2010SS is also available which features EXAIR’s No Drip design (patent pending), which will positively shut off the liquid flow when air pressure is removed. This eliminates unwanted drips which can ruin surfaces and waste expensive liquids. The 360° Circular Hollow spray pattern is a versatile nozzle that covers a variety of applications.

The EXAIR Model 1006SS - Back Blow Nozzle
The EXAIR Model 1006SS – Back Blow Nozzle

The 1006SS back blow nozzle features a number of orifices around the outside of the nozzle which force air back toward the operator and away from the air inlet. In most applications this will be used to pull water, chips, coolant, or debris out of the end of a pipe, channel, or tubing to clean the inner diameter. The Back Nozzles will typically be offered with a chip shield to contain any chips or debris from blowing towards the operator.

These two nozzles used in conjunction would work great to cool, clean, and dry the inside of, say, a welded pipe. The AT1010SS could be used to flush the inside of the pipe with water to cool the weld and blow out and weld slag or grinding dust from preparing the area. The 1006SS could pull out the water or debris from the inside of the pipe. The AT1010SS can be reinserted to spray the inside of the pipe with a rust inhibitor to maintain the quality of the weld until installation.  These nozzles work well together to clean the ID of the channel, tube or hose in your application.

EXAIR’s Free Efficiency Lab – How Much Money Can It Save You?

In many of my blogs, I talk about specific products benefits or applications, but this week I want to talk about a service that EXAIR provides to our customers: Efficiency Labs. The Efficiency Lab is comprehensive study of your current blow off. You can ship your current blow off to our facility. We can test it with our calibrated equipment and record your current product characteristics. Our most popular efficiency lab is testing home made blow offs. These are blow offs made from copper tubes, thumb guns with nozzles removed, or drilled pipe. These blow offs can get the job done, but they are noisy, wasteful and dangerous. Every compressed air expert knows that these blow offs need replaced, but sometimes it may difficult to decide which nozzle to use. By sending us your current blow off product(s) we can measure the force, flow, and noise of the blow off and provide a comprehensive report. This report, in most cases, compares your current setup against what EXAIR we would recommend to save compressed air, lower noise levels and maintain performance.

 In addition to providing a blow off suggestion, EXAIR’s efficiency lab can identify your energy cost for these blow offs. The standard industrial cost for compressed air is $0.25 per 1000 standard cubic feet. At first glance that might not seem like much, but it can add up. This week I did an efficiency lab for a customer that used 1/4 ID copper tube as their home made blow off.

open copper tube
This 1/4″ Open Blow off uses 30.8 SCFM of compressed air.

This small open tube ran continuously for 10 hours per day five days a week.

To run this tube, cost a company $1,175 per year. The tube would flow 30.8 SCFM of compressed air when fed with 80 PSIG. By installing an EXAIR Super Air Nozzle,  part number 1100, the company could save 16.8 SCFM of compressed air and $650 per year. Once again $650 may not seem like much, but they used up to (40) of these open blow offs depending on what part they ran. Replacing all (40) of these blow offs saves $26,000 per year at a capital investment of $2,880 for (40) 1100-9212, Super Air Nozzle with 12 inch stay set hose. That would be a simple ROI of 72 days.

That ROI is only taking into account compressed air cost. Additionally, the 1100 Super Air Nozzle will reduce noise by 28 dBA and it complies with OSHA Standard CFR 1910.242(b) for dead end pressure.

We have found that our customers all have unique setups which greatly vary the values of their particular blow off. Even if customers have the same 1/4″ tube, the way they implement it can greatly affect its performance. Variations in inlet pressure, length, diameter tolerance and even what they used to cut it to length can have an impact on how much air it will consume. If you want to know for certain how much air and money you can save, use our free Efficiency Lab service.

EXAIR can save a lot for you!

Complying with OSHA’s Compressed Air Standard

One of the most commonly misunderstood regulations about compressed air is, how to use it safely. OSHA requires a few key features to adhere to when using compressed air to clean. Many people come to the conclusion that the supply air pressure must be reduced to below 30 psig to safely use compressed air for cleaning. This will severely limit compressed air’s effectiveness. There are other ways to use compressed air safely, before we get to that though what has OSHA published on the subject.

meets or exceeds osha

OSHA’s directive 1910.242(b) states “Compressed air shall not be used for cleaning purposes except where reduced to less than 30 PSIG and then only with effective chip guarding and personal protective equipment.” This standard is unclear in a vacuum, but in 1978 OSHA released OSHA instruction STD 01-13-0001 (which also includes acceptable methods), which gave an interpretation on what “reduce to less than 30 PSIG” means. From the interpretation, The phrase, “Reduce to less than 30 psi means that the downstream pressure of the air at the nozzle (nozzle pressure) or opening of a gun, pipe, cleaning lance, etc., used for cleaning purposes will remain at a pressure level below 30 psi for all static conditions. The requirements for dynamic flow are such that in the case when dead ending occurs a static pressure at the main orifice shall not exceed 30 psi. This requirement is necessary in order to prevent a back pressure buildup in case the nozzle is obstructed or dead ended.”

This is technical speak for a nozzle that will allow a path for air to escape in case the nozzle is dead ended. EXAIR designs all of our products with this directive in mind. Typical compressed air safety nozzles feature an open tube with a cross drilled hole at the tip. This nozzle complies with the OSHA directive as well, but typically exceeds OSHA noise exposure standards and wastes compressed air. EXAIR’s engineered nozzles are designed to reduce the noise level below OSHA standards and use compressed air efficiently. This can greatly lower the energy cost of running your compressed air system.

EXAIR Model 1210-6-CS is shown.  This model meets or exceeds OSHA Standard 1910.242(a)

Secondly, in the interpretation OSHA requires effective chip guarding to further protect operating personnel. EXAIR offers Chip Shields which can fit all of our Safety Air Guns as well as many other blow guns. This Chip Shields feature a durable polycarbonate material to deflect and stop blowing chips from being directed toward the operator. This chip shield can help meet the requirements for OSHA 1910.242(b), but each company needs to carefully identify any operators that may be in the path of blown debris when using compressed air to clean.

If you would like to discuss your current blow off devices and see what model EXAIR offers to help you meet and exceed OSHA safety standards, please contact us.

Swivel This Or Swivel That

Untitled
The Nano Super Air Nozzle is available with an M6 x 0.75 thread OR a 1/8 NPT thread.

I recently took a call from a customer who was looking for a Nano Super Air Nozzle with a swivel and NPT threads.  We have two versions of this (see above) thanks to our plethora of options.  We offer a newer Mini Swivel Fitting that will allow the M6 thread of the Nano Super Air Nozzle to go straight into the swivel joint and it gives you a 1/8″ MNPT on the opposite side.  This still permits the 25° from center range of motion as the standard swivels do but, with a smaller footprint,  is able to get into tighter spaces.

The other option is to utilize a model 1110SS-NPT which is a Nano Super Air Nozzle w/ 1/8″ NPT adapter, then add a 1/8″ NPT Swivel fitting which is a model 9052.  This option is a little bulkier, but if you needed some extra length on the nozzle side to get closer to the target area then it would be helpful.   This unit also offers the 25° from center range of motion and still gives a 1/8″ MNPT thread to plug into your system.

1110SS-NPTW - Nano Super Air Nozzle w/ NPT Adapter and 1/8" NPT Swivel Fitting
1110SS-NPTW – Nano Super Air Nozzle w/ NPT Adapter and 1/8″ NPT Swivel Fitting

As you can see in the picture above, the Mini Swivel fitting with Nano Super Air Nozzle is a more compact option, but does not reach as far as the standard 1/8″ swivel with NPT Nano Super Air Nozzle.  No matter the case, we have them both in stock and ready to ship same day on orders received by 3 PM EST that are shipping within the states.

Chances are if you have a need for a compressed air blow off, we will have more than one way to get the job done.   Our goal is to sell you the best engineered solution that will get the job done and make your life easier.  If you would like to discuss any of your applications, please contact us.
