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.

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.

Stay Set Hoses & Magnetic Bases – Precise Positioning for your Blowoff Application!

sshapp2

Once you’ve selected an engineered compressed air nozzle for your blowoff application, you’ll likely need a solution to mount and position it as well. In some applications you may be able to simply replace the old solution with a similar thread, but if the installation is a bit more complex, or if it is a new installation entirely, you’ll need a means to do so. Here’s where EXAIR’s Stay Set Hoses and Magnetic Bases come into play.

sshfam2

EXAIR’s Stay Set Hoses are available from 6”-36” in length with ¼ NPT male threads on each end, or a ¼ NPT male on one end and 1/8 NPT female on the other. The Stay Set Hoses are rigid and allow you to maintain precise positioning of the blow off nozzle. The hoses have “memory” and will not creep or bend. They’re easily repositioned as well, making them an ideal solution for applications that may require moving them around due to varying parts.

Stay Set Hoses can also be installed on any Soft Grip Safety Air Gun. Simply adding a suffix to the end of the any of the Soft Grip Air Gun model numbers will come with the Stay Set Hose installed. For example, the gun below is a Model 1230-36SSH. A Model 1230 Safety Air Gun, with a 36” Stay Set Hose installed. Having a Stay Set Hose on your air gun can allow you to reach into tight or awkward places that a traditional air gun won’t permit.

Model 1230-36SSH

In addition to the Stay Set Hoses, EXAIR also has Magnetic Bases available as well. The powerful magnet permits both horizontal and vertical mounting. A manual valve is also included that will allow you to vary the force and flow. Magnetic bases are available with one or two outlets and can be combined with any of our nozzles and Stay Set Hoses to create your own customized blowoff system.

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.

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).

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.

Many Ways to $ave on Compressed Air Costs

Using compressed air in the plant is common for many types of processes.  Typical uses are drying, cooling, cleaning and conveying. Compressed air does have a cost to consider, and there are many ways to keep the usage and the costs as low as possible.  The first step is to use an EXAIR Intelligent Compressed Air Product, which has been engineered to provide the most performance while using the least amount of compressed air. The next step is to control the use of the air, to only have it on when needed.

EXAIR offers the EFC – Electronic Flow Control.  It offers the most comprehensive method to maximize the efficiency of compressed air usage.  It combines a photoelectric sensor with a timing control that operates a solenoid valve to turn on and off the air as required. With 8 different program types, an on/off mode that works with any process can be programmed ensuring that the minimum amount of compressed air is used.  You can use the online EFC Savings Calculator to see how quickly the savings add up!

EFC – Electronic Flow Control

Another method would be to use a solenoid valve with some other method of control. Depending on the process, the solenoid could be energized via a machine control output, or as simple as an electrical push button station. EXAIR offers solenoid valves in a variety of flow rates (from 40 to 350 SCFM) and voltages (24 VDC, 120 VAC and 240 VAC) to match the air flow requirements of the products we provide, while integrating into the facility and available supply voltages.

For control of the Cabinet Cooler Systems, the ETC – Electronic Temperature Control, uses a thermocouple to measure cabinet temperature and cycle the system on and off to maintain a precise cabinet temperature, and provides a digital readout of the internal temperatures and on the fly adjustment.  Also available is the Thermostat Control models, which utilize an adjustable bimetallic thermostat to control the solenoid valve, also cycling the unit on and off as needed to maintain a set cabinet temperature.

ETC CC
ETC – Electronic Temperature Control

There are several manual methods that can be used to control the compressed air.  A simple valve can be used to turn the air off when not needed, whether at the end of the work day, at break time, or whenever the air isn’t required.  We offer several options, from a foot controlled valve, to a magnetic base with on/off valve, to a simple quarter turn ball valve.

Atomizing Nozzle Helps Defeat Odor

A customer was faced with a problem. She worked at a local garbage dump. People would bring their garbage every week to dispose. Her responsibility was to keep track of the local patrons. On the warm days, the smell was at its peak. They supplied her with a limited amount of fragrance sanitizer to help with the smell, but depending on the amount of warm days and the amount of refuse, she was sometimes in the “stink”. She saw our advertisement about how EXAIR can save fluids and money with our atomizing nozzles. She purchased our SR1010SS nozzle. It is our siphon fed round pattern style nozzle. With a small air compressor, she was able to spray a small mist of fragrance. She could even adjust the amount with the liquid adjustment stem for those warm days.   Thus, she was able to save the company money by conserving the fragrance and have enough good smell around her to keep her nose happy.

Atomizing Nozzle
Atomizing Nozzle

EXAIR offers a large line of atomizing nozzles. We use them in washing, rinsing, coating, cooling, quenching, humidification, and dust control. If you are able to pressurize the liquid, you can use the internal and external mix nozzles. In applying a mist instead of a spray, you will be able to save material. To even help more in the savings, we also offer the No Drip Atomizing Nozzle. This product is great if you are starting and stopping a process. As soon as the pressure is released, a seal is applied to keep the material in the atomizing nozzle.

If you want to apply liquid using compressed air, EXAIR could have the product for you. With a little ingenuity and help from your application engineer, we could turn waste into wonder.

Dead End Pressure

With all the warm weather and outdoor activities around the house the past few weeks I had somewhat forgotten about a nice wasp nest that had been constructed in between the front door to our house and my bedroom window.  This also happens to be right in the corner of two walls and in the deepest portion of the landscaping.   Like I said though, I had forgotten about it for a few weeks which gave the inhabitants enough time to double the size of the nest.

20140616_205441

With that being said, I didn’t want to use wasp or bee spray because it means I would have to get close to the nest and I have a strong belief that all of those products just make them really angry and don’t bring death right away.  I wanted the nest to have a quick death because then I don’t have to run around my yard, screaming, because I have a wasp chasing me after destroying their home.

I cam up with several methods to get rid of the nest.

1.) Brake Cleaner – Very effective, however the nest was also right above our air conditioning condenser so that was out.

2.) Small controlled burn – In my experience it is never small nor controlled.   Plus it was way to close to the dry roofline.

3.) 3,000 psi of water in a jet stream from the pressure washer.  WINNER!!!!

20140616_205457

So I set out to the front of the house with the pressure washer and hose in tow.  Get everything setup and notice that there is one sentry wasp sitting right at the entrance.  So I simply got the nozzle of the gun with pin point spray as close as I could and as soon as the wasp started to move I shot the entire nest off the house.   Then I proceeded to shoot it back and forth in the landscaping until I saw no survivors.

That was 3,000 psi of water that tore through a nest and rid my house of a pest.  This made me think of just how little pressure the human skin can take.  OSHA standard CFR 1910.242(b) guards against a mere 30 PSIG. Higher pressure air, when blocked up against our skin, has the potential to push air into our bloodstream and cause air embolism – a serious threat to our health. Too many commercial air nozzles and guns, open pipes and homemade blow off violate this OSHA standard and pose a threat to personnel.

EXAIR engineered air nozzles and products have been designed to eliminate the possibility of being dead-ended (blocked). This is why all of EXAIR’s products meet or exceed the OSHA standard 1910.242(b) for 30 psi dead-end pressure.  None of our products can be dead ended and cause bodily harm when used properly.  These engineered features also reduce noise levels and minimize air consumption. So if you are concerned with any of your compressed air applications, and just how safe they are, contact us.
