Super Air Nozzles and Stay Set Hoses to Replace Open Tubes

I recently worked with an company that performs energy audits and they were working with a food company to review and propose ways to reduce the energy consumption throughout the plant. One area where we were able to help was on an onion peeling machine, shown below:

Vegetable Peeler Wide
Onion Peeler With Screw Conveyor and Blow off Tubes

The area of machine in question used a screw conveyor and friction source to help loosen the peels and fifteen (15) 1/4″ O.D. open ended tubes, which were noisy and unsafe, to blow the peels completely off and away form the onion. The auditor was able to install an air flow meter on the system and found that the machine was consuming 220 SCFM of compressed air for this operation.

(15) Total, 1/4″ Tubes Used to Blow Air and Help Remove the Peels

We proposed to replace the tubes with a 6″ Stay Set Hose and the model 1103 Mini Super Air Nozzle.  Each model 1103 Mini Super Air Nozzle will consume just 10 SCFM of 80 PSIG compressed air. Attached to the 6″ Stay Set Hose, the nozzle can be placed exactly where needed and aimed appropriately. A strong blast of air rated at 0.56 lbs (9 ozs.), and ultra quiet at 71 dBA, the Mini Super Air Nozzle delivers the results needed.

The Stay Set Hose has “memory” and will not creep or bend, simply install the 1/4 NPT fitting into the compressed air supply side, an thread the 1/8 NPT Mini Super Air Nozzle into the other end and position as needed!

Fifteen (15) of the Mini Super Air Nozzles will pass 150 SCFM of compressed air compared to the current usage of 220 SCFM, resulting in a 70 SCFM drop, or a 31.8 % reduction.  At a typical cost of $0.25 per 1000 Cubic Feet of Compressed Air, the nozzles would save $1.05 per hour of operation. Rate of Return yields a full pay-off in just 43 days of operation (24 hours per day operation)!

If you are looking for ways to save on compressed air usage in your facility that is safe to operate and quiet to use, we will have a solution for you.

If you have questions about any of the 16 different EXAIR Intelligent Compressed Air® Product lines, feel free to contact EXAIR and myself or any of our Application Engineers can help you determine the best solution.

Small, Precise Blowoff at Your Fingertips

For many blowoff applications, stronger isn’t necessarily better.  For applications and processes where a light, but effective blast of air is needed for cleaning and drying, the VariBlast Compact Safety Air Gun with the Atto, Pico, or Nano nozzle fits the bill. The smallest of the EXAIR engineered Super Air Nozzle family, the Atto, Pico, and Nano have been designed to provide the smallest, most precise blowoff possible. The focused airflow pattern allows for very accurate control and placement of the air stream.  The nozzles are available in both Type 316 Stainless Steel and PEEK plastic (useful for harsh environments, and is non-marring)

VariBlast Model 1698SS, with Stainless Steel Nano Super Air Nozzle

The Atto, Pico, and Nano nozzles use very little compressed air and are extremely quiet, easily meeting OSHA Standard 29 CFR 1910.95(a) for Noise Exposure.  The design incorporates engineered solutions for safety and can be supplied with higher pressure compressed air and meet OSHA Standard 29 CFR 1910.242(b), relating to dead end pressure requirements.

The table below provides performance data, including the compressed air consumption, force, and sound level for the various configurations.

VariBlast With Small Nozzles

Note that the VariBlast air guns can be had with extensions from 6″ to 72″ and chip shields to meet the performance and safety needs of any application.

The Atto, Pico and Nano Nozzles can also be configured to work with the Soft Grip style of Safety Air Gun.  Consult an Application Engineer for assistance in choosing.

If you have any questions about the Atto, Pico, or Nano nozzles, the VariBlast Compact Safety Air Gun, or any EXAIR compressed air product, feel free to contact EXAIR and myself or one of our Application Engineers can help you determine the best solution.

EXAIR Flat Super Air Nozzles – Adjustable, Flexible and Powerful

As an Application Engineer here at EXAIR, we get calls from customers looking for an air knife, but shorter than our typical 3″ stocked size.  We can make an air knife to any length needed, but we will look at the 1″ and 2″ Flat Super Air Nozzles as a possible solution.

Like an air knife, the Flat Nozzles provide a wedge shaped pattern of air that maintains the width of the nozzle, to create a concentrated, powerful air flow.  Thus, a 1″ Flat Super Air Nozzle has air stream 1″ wide, and the 2″ Flat Super Air Nozzle has one 2″ wide.

The Flat Super Air Nozzles are available in zinc aluminum alloy or type 316 stainless steel construction, to meet environmental conditions of the process.  Both the 1″ and 2″ nozzles contain a changeable, patented shim that maintains the critical air gap, which allows the release of a precise amount of air through the thin slot, across a flat surface. The result is a wide, forceful stream of high velocity, laminar airflow, with minimal air consumption and noise.

1″ and 2″ Flat Nozzles, in Zinc aluminum Alloy and Type 316 Stainless Steel

Shims are available in thicknesses of 0.005″, 0.010″, 0.015″, 0.020″, 0.025″, and 0.030″.  Shim Sets with either 2 or 3 shims are available for both sizes to allow for adjustment of the performance to best meet the application need.

Flat Super Air Nozzles – Quiet and Forceful and Adjustable

The 2″ Flat Super Air Nozzle is a very powerful yet quiet engineered nozzle.  Operation at 80 PSIG of compressed air pressure yields a strong 1.38 lb. of force, at only 77 dBA of sound level.  Compare this with many of the plastic flat nozzles that blow air through a series of holes, with sound levels ranging form 78-83 dBA, not to mention some might violate the OSHA dead ended pressure standard and results in fines being levied.

The patented technology utilizes a changeable shim to generate the high flow of air in a smooth and laminar flow, to keep noise down and power and strength up. With (6) stainless steel shim thicknesses available, the 2″ Flat Super Air Nozzle offers a very flexible package that can be set and tuned to meet exacting performance criteria, while using the minimum amount of compressed air, and at the quietest possible sound levels.

2 Inch Flat
2″ Flat Super Air Nozzle

The model 1122 is offered in a zinc aluminum alloy body and cap, and the 1122SS is constructed from type 316 stainless steel.  All shims are stainless steel. The shim thickness for the 1122/1122SS is 0.015″ thick.

Also available, for extra blowing force, are the HP1125 and HP1125SS.  The nozzles utilize the same zinc aluminum alloy or stainless steel body and cap and have the 0.025″ shim installed – and deliver 2.2 lbs of force, while only increasing sound levels to 83 dBA.

Shim sets for any of the 2″ Flat Super Air Nozzles are available.  The 1132SS shim set includes shims of thickness of 0.005″, 0.10″, and 0.020″.  For higher force levels, the HP1132SS shim set includes the 0.020″ and 0.030″ shims.

Shims are available, from 0.005″ up to 0.030″ for maximum versatility and performance tuning

As you can see- for a versatile, forceful and quiet engineered air nozzle, it is hard to beat the EXAIR 2″ Flat Super Air Nozzle.  If a 1″ wide nozzle better suits your needs, the same flexibility and power can be found in the 1″ Flat Super Air Nozzle as well.  Check it out as well.

Coast to Coast and Beyond

Recently, I was working with  a customer looking for a Premium Reversible Drum Vac and wanted it shipped to the Northwest Territories of Canada –  which we could do!  It got me to thinking, what are the farthest US state and territory locations EXAIR has shipped to in the North, South, West and East directions.  I ‘scoured’ the records and came up with these.

Furthest North- We have shipped to Prudhoe Bay, Alaska.  Most recently, believe it or not, we shipped a NEMA 4X Cabinet Cooler to an Oil and Natural Gas Exploration Company.  Goes to show that even the coldest environments still have the need to provide cool, clean, dry air to cool and protect electronics in electrical enclosures.

Furthest South – We have shipped to the US Territory of Puerto Rico, city of Santa Isabel.  An Aerospace company needed a strong, laminar blast of air and utilized a 6″ Stainless Steel Air Knife.  An Air Knife offers a quiet, efficient way to clean, dry or cool parts, webs, or conveyors.

Furthest West- We have shipped to the US Territory of Guam.  The local University ordered a model 1111-4 Super Air Nozzle Cluster, for a good strong blast of air flow for a cleaning operation.  The model 1111-4 delivers 3.2 lbs of force, at just 82 dBA of sound. A safe and efficient nozzle for blowoff operations.

Furthest East- We have shipped to Eastport, Maine.  The customer in Eastport ordered a Line Vac and a section of Conveyance Hose.  The Line Vac is a great tool for conveying large volumes of material over long distances, through a standard hose or tube.  The compact design features large throat diameters for maximum throughput capability.

 

It was interesting to look back and see all the places that EXAIR has shipped.  We have customers from all over the globe. If you are outside the of 50 US States and Canada, we have a dedicated team of International Application Engineers that will work with you to select the best EXAIR product for your process and application, and direct you to your local International Distributor.

Engineered Air Nozzles and Jets Outperform – Save Air, Increase Safety, Save Money

EXAIR’s Engineered Air Nozzles and Air Jets provide a simple solution to lower compressed air usage and reduce noise levels for compressed air blowoff operations.

Why Air Nozzles and Jets – When compared to commonly used open copper tubes or pipes, compressed air savings can be as high as 80%. And with less compressed air, sound levels are greatly reduced.  A 10 dBA noise level reduction is typical.  All EXAIR Air Nozzles and Jets meet the Occupational Safety and Health Administration (OSHA) maximum dead end pressure and sound level exposure requirements. They also carry the CE mark.

nozzlescascade2016cat29_559
The largest selection of engineered Air Nozzle sizes and materials are only available form EXAIR 

EXAIR Nozzles are engineered to take advantage of the Coanda effect to amplify the airflow up to 25 times or more. Compressed air is ejected through the small orifices and surrounding air is entrained into the main stream. The resulting air stream is a high volume, high velocity blast of air at minimal consumption.  EXAIR manufactures many styles, from the very small, but powerful Atto Super Air Nozzles, to the largest 1-1/4 NPT Super Air Nozzle.  Also offered are 1″ and 2″ wide Flat Super Air Nozzles, and the Back Blow style for cleaning out tubes, pipes, channels or holes from 1/4″ to 16″ in diameter.
EXAIR Air Jets utilize the Coanda effect (wall attachment of a high velocity fluid) to produce air motion in their surroundings.  A small amount of compressed air (1) is throttled through an internal ring nozzle above sonic velocity.  A vacuum is produced, pulling in large volumes of surrounding, or ‘free’ air, through an around the jet (2).  The exit flow is the combination of the two air sources (3).

air-jet
How an Air Jet Works

EXAIR manufactures Air Jets in two types, High Velocity, and Adjustable with materials of construction of brass and Type 303 Stainless Steel.  The High Velocity Air Jet uses a changeable shim to set the gap, controlling the force and flow of the air.  The Adjustable does not use a shim, and has a micrometer gap indicator and locking ring to allow for varying force and flow performance.

Out With the Old and In With the New

Oh really!!  Being in my senior years I’ve been around long enough to see things come full circle. What is being touted today as new is merely something recycled from the past with a new coat of paint.  I have a closet full of ties: wide ones, thin ones, stripped ones, paisley prints, stripes, and colors of all sorts. I don’t throw them away because over time they come back into style.

When we were kids, Mom reused jelly jars for juice glasses. Grandma recycled flour sacks into pillow cases. Anything headed for the dump Dad stripped of its nuts and bolts and saved them in recycled baby food jars. As we outgrew our clothes, we recycled them down to our smaller siblings.

Then there came the era of “planned obsolescence“.  The idea was not to make products designed to last, but they should be made cheaply and simply discarded and replaced. This would create jobs and stimulate a robust economy. So we became a wasteful, consuming, throwaway society.

Today we have come full circle. Catch phrases such as sustainability, recycle, and conserve are the rage. Oh really! That’s what we used to do. So is this really new or simply recycled from the past with a new coat of paint?

EXAIR does not subscribe to planned obsolescence. For 27 years we have built our products to last and back it up with a 5 year built to last warranty. Nozzles, jets, and air knives have been around forever. So their basic concept is not new. What is new is what EXAIR has done to design them to conserve compressed air, operate at low sound levels, and be compliant to OSHA directives without sacrificing performance.

If you need help in retrofitting your inefficient nozzles or have an application that requires the use of compressed air call one of our application engineers at 1-800-903-9247
