Air Nozzles Blowoff Guide Available For FREE

Are you looking for an engineered Air Nozzle to replace your existing unsafe open pipe? Maybe you are wanting to reduce the sound level in your facility or decrease your energy costs? EXAIR offers a large variety of Air Nozzles that are ALL OSHA compliant to meet or exceed OSHA Standard 1910.242(b), by eliminating any potential for dead-ending the air flow out of the nozzle and keeping the outlet pressure safe. The design of our Super Air Nozzles ejects the compressed  air behind a series of fins so there is always path for the air to escape, meaning they cannot be dead ended.

OSHA Noise Level

ALL of EXAIR’s Air Nozzles meet or exceed noise exposure levels.

In addition, our air nozzles meet the OSHA Standard 29 CFR – 1910.95(a) for allowable noise exposure levels. Excessive noise in the workplace can cause stress, lack of concentration leading to accidents and potential long term hearing loss (More OSHA Noise Induced Hearing Loss info here). EXAIR’s air nozzles entrain surrounding ambient air up to 25 times for every 1 part of compressed air, producing much less wind shear, reducing the output sound level, while also making our units more efficient, consuming less compressed air.

Where Did All The C Clamps Go?

Over the past week I visited a local company here in Cincinnati that utilized a decent number of flat plastic air nozzles on their production lines.   This style nozzle had been used for many years but were the reason their engineering department contacted EXAIR.   The nozzles they had in place were used in many different applications from ejecting bad parts, holding up box flaps, and even positioning product correctly on the production line.   Every nozzle was tied to a regulator somewhere on the machine and all of the regulators were tuned to different pressures.

The customer was experiencing, at certain points during the day, a pressure drop throughout the entire system that would cause packaging lines to shut down due to low air pressure faults. The customer called EXAIR because they determined the plastic nozzles were using too much compressed air and were also a constant maintenance problem. Primarily, they wanted to see if we had a solution to lower compressed air while still achieving the desired production results.

Being local we were able to visit the customer and after discussing the applications we set out through the manufacturing area to discover if we could offer solutions for the problematic areas. We got about 10′ away from a casing machine and I heard a loud hiss of compressed air.   This was even with my foam ear plugs in.  Once we reached the edge of the machine I was quickly able to trace the sound down to a plastic flat nozzle that had been mounted to the machine, broken and held back in place by a large C clamp like seen below.

As we went through the rest of this production line and the rest of the packaging facility, it was clear the customer had settled on using flat plastic nozzles throughout the plant. Generally we see this because the nozzles are cheap – when you forget to consider operating and maintenance costs. This was not the only broken nozzle being held in place by a clamp and it is also the not the only one that was using more compressed air than necessary.

After finishing the tour and performing some tests here in our lab I recommended that they utilize our 1″ Flat Super Air Nozzle with a .005″ thick shim installed.   By installing the 1″ Flat Super Air Nozzle they are going to be able to mount the metal nozzles with minimal modification to their existing setup as well as lower air consumption and noise level. The metal construction makes them more durable and long lasting in an industrial environment. These nozzles will not break when an operator bumps it and the maintenance department will be able to reclaim all the C clamps that are distributed throughout the facility.

Once we have final numbers on how many nozzles have been replaced and what pressures each nozzle is operated at we will provide the customer the air consumption savings as well as the noise level reduction that they are seeing throughout the plant.

EXAIR’s New Ion Air Cannon Static Eliminator

8192_iac_sideview2top (924x1024)

Model 8192 Ion Air Cannon


EXAIR Corporation has introduced a new design for our Ion Air Cannon. The new design is able to perform all of the same functions as our previous model with
the additional features that the product is even more rugged to withstand the rigors of industrial, everyday use in a variety of applications. The Ion Air Cannon performs on bench-top applications, can be mounted to a wall or ceiling, or placed in tight spaces within machinery to eliminate static. 

The New Ion Air Cannon, Model 8192 still has the UL component recognition for the US and Canada. It is also OSHA compliant for dead-end pressures in that it keeps the output pressure well below 30 PSIG when dead ended. Keeping our RoHS compliance was another important factor when putting together the new Ion Air Cannon design parameters. Beyond these compliances, the New Ion Air Cannon is also CE compliant to applicable European directives for safety as well as electromagnetic interference.

With the new design, we have integrated the grounding reference into the high voltage cable so there is now only one connection that must be made at the power supply for the high voltage signal as well as the return path for Earth ground. We have also changed the cable construction to be built using a PVC coated, stainless steel, armored cable to withstand many common hazards, thus protecting the internal conductors as well as providing electrical shielding to maintain CE compliance.

The modular, high voltage, cable assembly is also removable to allow for cleaning and replacement of the solid, stainless steel emitter point to insure problem free operation. The New Ion Air Cannon comes standard with a 5 ft. long, high voltage cable. However, other cable lengths up to 50 ft. are available by request for applications where mounting the Ion Air Cannon remotely from the power supply is necessary.

When powered by Model 7960, dual input voltage, Power Supply, the new, model 8192 Ion Air Cannon remains shockless to operators and incorporates over-current protection by means of an integrated fuse in the power supply as well as a shunting secondary to lower the voltage output to zero volts should the high voltage cable become damaged and cause a shorted condition.

The New Ion Air Cannon will make a substantial addition to any application requiring a flexible static eliminating solution to be mounted and operated by personnel working in packaging, finishing, plastic molding, pre-paint dust removal and many more applications.

Give the New Ion Air Cannon a try. You will be pleased with the fast static decay times and impressed with how easy it can remove static in your application.

Sometimes it can be too hot for a Robot

Robots are awesome for repetitive operations in harsh environments.

In this instance, a manufacturing plant was using a robot arm to remove parts from a molding machine. They were having issues with the electronics overheating.  They decided to do a thermal imaging scan, and they found that the heat was coming from their treatment furnace.  As you can tell with the image below, the high temperature (light orange color) was radiating onto the robot enclosure.  The temperature at the cover was at 60.6 deg. C (141 deg. F).  This was too hot for proper operations.  So, they contacted us to see if we could suggest a product to help keep their robot cool.

Thermal Image Temp = 60.6 deg C (141 deg. F)

Temp = 60.6 deg C (141 deg. F)

In reviewing the elevated ambient temperature and the dimensions of the enclosure, I determined that our HT4215 High Temperature Cabinet Cooler would work great in this application. Our HT Cabinet Coolers are designed to handle ambient temperatures from 52 to 93 deg. C (125 – 200 deg. F).  They can be mounted easily onto the enclosure, and the internal profile is small as not to contact any of the components inside.  The Cold Air Distribution Kit (included with this model) can maneuver the cool air to the hotter areas and to the more sensitive electronics.

Once it was installed, the robot was functioning without issues or shut downs. If you have issues in a harsh environments, please do not hesitate to contact one of our Application Engineers at 800-903-9247.  We may have something that can keep your operation running smoothly.

EXAIR E-Vacs For Pick-And-Place Applications

Over the last two weeks I’ve trained a number of our distributors on EXAIR products.  We’ve discussed the benefits of engineered compressed air products, the way these products can impact a company’s bottom line, and how they work.

One of the topics which is sure to produce good conversation is our vacuum generator product line, the E-Vacs.  Using a compressed air powered venturi to produce vacuum, the E-Vac is attractive for a number of applications because the vacuum flow is instantaneous.  This means we can produce vacuum only when and where it is needed rather than keeping a vacuum pump in continuous operation.

Power supplies to be lifted with EXAIR E-Vacs

This instantaneous nature of the E-Vac was recently attractive to an end user in need of a better method to handle electronic power supplies used in their computer production process.  They wanted the lifting and placement of the power supplies to be semi-automated, with an operator turning the lifting system on and off.

This type of application is perfect for an E-Vac.  In order to determine the best solution, for this or any E-Vac application, we have to first determine the following:

  1. Is the material/item to be lifted porous or non-porous?
    1. Porous materials will have leakage through the material itself, or through inconsistencies in the material surface. Items such as cardboard, fabrics, or a golf ball are considered porous.
    2. Non-porous materials will not have leakage through the material. Items such as smooth glass and flat plastics are considered non-porous.
  2. What is the weight of the item to be lifted?
  3. How will the item be lifted?
    1. Will the vacuum cups mount to the top of the workpiece to the side? This will determine if the suction cups will be in a horizontal or vertical plane when lifting the product.

Dimensions of the workpieces

Using this information we can determine the proper safety factor to apply (2 for horizontal orientation of the vacuum cups, 4 for vertical orientation), and the potential vacuum cups to be used.  Then, based on size of the workpiece and space constraints we can select the proper vacuum cups.  And finally, using charts on file with the EXAIR Application Engineering department, we can select the correct E-Vac or E-Vacs for the application.

If you have a pick-and-place need in your facility, contact an EXAIR Application Engineer.  We’ll be happy to help choose the right components for your setup.

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:

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.

Selecting An EXAIR Air Knife

Many times we receive a  call from a customer looking for an Air Knife but they are unsure which design is the best to suit their needs. With 3 options to choose from, the Super Air Knife, Standard Air Knife and Full-Flow, it can seem like a somewhat daunting task so lets take a look at some of the key differences between the units. We keep all of these models in stock and can ship same day on orders we receive by 3 pm.

Super Air Knife

EXAIR Super Air Knife

Let’s start with our most popular choice, the Super Air Knife. The Super Air Knife is our most efficient unit, using a 40:1 amplification rate of entrained surrounding air to compressed air, it consumes only 2.9 SCFM per inch @ 80 PSIG while maintaining a low sound level of 69 dbA. This unit produces a laminar airflow across the entire length of the knife and there are air inlets on each end, as well as on the bottom. We offer lengths from 3″ up to 108″ in aluminum, 303ss, or 316ss. Additionally we offer lengths up to 54″ in PVDF (Polyvinylidene Flouride) for applications requiring superior chemical resistance, like those associated to acids, solvents or aggressive chemicals. There are 1/4-20 tapped holes on the bottom of the knife which can be used for mounting. We recommend the Super Air Knife most often because it uses the least amount of compressed air and has the most even airflow from end to end.

Std Air Knife

Standard Air Knife

Secondly we offer our Standard Air Knife which provides a 30:1 amplification rate, consuming slightly more compressed air at 3.4 SCFM per inch @ 80 PSIG. These units are louder at 83 dBA and feature air inlets on each end. Lengths available from 3″ up to 48″ in aluminum or 303ss construction.  The airflow length is 1″ smaller than the length of the knife (1/2″ of no flow on each end), for example a 12″ Standard Air Knife has a 13″ physical length with a 12″ airflow length. This is the first knife we ever manufactured and is a solid choice with good performance.

Full-Flow

Full-Flow Air Knife

Lastly, the Full-Flow Air Knife. Again providing a 30:1 ratio of entrained ambient air to compressed air, has the smallest dimensional footprint. Air consumption is slightly less than the Standard Air Knife at 3.1 SCFM per inch @ 80 PSIG with an airflow length equal to the length of the knife. We offer lengths from 3″ up to 36″, again in aluminum and 303ss and the air inlets are on the back of these units. The Full Flow Air Knife fills the need for customers with limited mounting space and who cannot fit a Super Air Knife into the desired location.

Hopefully this information will help in making the best decision to fit your needs. Of course if you still need additional support, please don’t hesitate to contact one of our Application Engineers for assistance.
