Don’t BOO Safety

This week is one the favorite times of year of my son..… HALLOWEEN! The haul of candy aside, he loves getting to wear his new costume (this year it’s Jack Skellington from A Nightmare before Christmas), walking through the neighborhood to see all of the decorations,  and enjoying the other costumes.

Jack-Skellington-jack-skellington-21236750-312-306

We get a lot of traffic in our neighborhood, with 6 streets running parallel and it’s all flat. As a result of the high traffic, some of our neighbors treat this as a time to compete and go all out with the decorations. So not to be outdone, one of them has decided to set up a mini haunted maze in their backyard – complete with smoke machines, strobe lights, bales of hay, cobwebs, spiders, skeletons, headstones and even a working guillotine! The kids are going to enter from the side yard and once they work their way through the maze, they pull on the guillotine’s rope to reveal the (skull) bucket of candy! Pretty ingenious and WAY more work than I would have done, but I am sure it will be a huge hit!

As they were showing me their “invention”, I started to wonder how safe this was going to be and could only imagine that some parents are going to be like me, a little concerned. They assured me that everything was going to be fine, they had our Township office inspect the maze and were able to secure a permit. Since the Township is aware that the neighborhood draws a lot of visitors, they even agreed to have volunteer firefighters assist with the operation and provide a safe(r) attraction.

Safety should also be a primary concern when implementing compressed air applications in your workplace. By using open ended pipe or tubing, you are creating an unsafe work environment, risking serious injury due to high pressure and extended exposure to extreme noise levels. All of EXAIR’s Intelligent Compressed Air Products have been designed and engineered to meet or exceed OSHA Standard 1910.242(b) for 30 psi dead end pressure and OSHA Standard 29 CFR 1910.95(a) for allowable noise exposure.

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.

OSHA Standard 29 CFR 1910.95(a):

OSHA Noise Level

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.

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.

Why 5 PSIG Matters

Last week I pointed out the important locations for measuring your compressed air system pressure throughout your compressed air system.   One of the critical points to measure system pressure was before and after each filter.  This leads into another question that I receive every once in a while, “How do I tell when the filter needs to be changed?”  The answer to this is easy, when you see more than a 5 PSIG pressure drop across the filter.  This means that the element within the filter has become clogged with sediment or debris and is restricting the volume available to your downstream products.

This can lead to decreased performance, downtime, and even the possibility of passing contaminants through the filter to downstream point of use components.  In order to maintain an optimal performance when using EXAIR filter separators and oil removal filters, monitoring the compressed air pressure before and after the unit is ideal.

Replacement filter elements are readily available from stock, as well as complete rebuild kits for the filter units. Changing the filters out can be done fairly easily and we even offer a video of how to do it.

The life expectancy of a filter element on the compressed air is directly related to the quality of air and the frequency of use, meaning it can vary greatly.  If you tie a new filter onto the end of a compressed air drop that has not been used in years, you may get a surprise by the filter clogging rather quickly.   However, if you maintain your compressor and your piping system properly then the filters should last a long time. Generally we recommend checking your filters every 6 months.

If you have questions about where and why to filter your compressed air contact us.

Super Air Wipe Removes Unwanted Water In Application

Super Air Wipe

EXAIR’s Super Air Wipe removes water from a cooling bath on a plastic coated wire production line.

In an email sent to me from a Russian reseller I was asked for assistance with an Air Knife application, and whether we could make a circular knife to assist blow off of industrial oil.  Fortunately, we not only can, but we do and we have them in stock.  Our Super Air Wipe is a formidable product to assist with OD blow off of a variety of applications.

For example, one of our distributors is working with their client on a way to increase production line speed.  The application has a plastic coated line that passes through a dip tank after a certain stage in the production process.  After treatment and before the next stage which takes place in a closed-top container, the water on the surface of the plastic line needs to be removed.

To remove the water and allow for faster line speed (thereby allowing for greater throughput in the application) a Super Air Wipe is installed.  The Super Air Wipe can blow off the excess water, preventing/removing a process disturbance at the next stage in production.

All EXAIR products are designed to maximize the use of compressed air, and to solve problems in industrial applications.  If your application has a need for a compressed air based solution, contact an EXAIR Application Engineer.

How To Choose An Air Knife

The EXAIR Super Air Knife has a prominent place near the front of our catalog, and THIRTEEN pages of photos, application details, performance data & specifications. It’s the most efficient and quietest product of its kind on the market, and our most diverse product offering in terms of size range, operational adjustability, materials of construction, and accessories available. For almost any general industrial air blow off application, the EXAIR Super Air Knife is the superior choice in terms of air usage, sound level, and capability.

EXAIR Super Air Knives come in a wide range of lengths, for a wide range of possibilities.

EXAIR Super Air Knives come in a wide range of lengths, for a wide range of possibilities.

As tireless champions of the causes of reducing air consumption and noise, we’re always going to promote these benefits of the Super Air Knife. Still, a caller asked me the other day, “Well, why do you still make the others?”…meaning, of course, our Standard and Full Flow Air Knives. Why, indeed:

*Given the same air supply pressure, the Standard Air Knife generates the highest force of our three styles. The amount of force applied isn’t always a prime consideration…if you think about one of the more “textbook” applications for an Air Knife, it doesn’t take a great amount of force to blow off dust and light debris from a conveyor belt…certainly this is a case where efficiency factors in: the lower air consumption of a Super Air Knife can pay for the cost difference between it and a Standard Air Knife in as little as three months of operation.

The Standard Air Knife has the highest force, for when it's needed.

Of course, if you’re blowing stubborn debris out of tight spaces, like gummy, greasy dirt that’s accumulating in the recesses of a finned tube heat exchanger, that extra force can make all the difference. No; the Standard Air Knife isn’t as efficient or quiet as the Super Air Knife, but it’s still a far cry better than a drilled pipe.

*While the Super Air Knife is pretty compact – you only need a few square inches of profile area to successfully mount it – the Full Flow Air Knife is even smaller, requiring not much more than one square inch of profile for mounting. With ports on the rear face (instead of the ends & bottom for the Super Air Knife,) they can fit in very tight quarters.

Low profile and lightweight, the Full Flow Air Knives are a great fit for tight quarters.

Low profile and lightweight, the Full Flow Air Knives are a great fit for tight quarters.

The Full Flow Air Knife is also the lightest weight for a given length. A 36” Aluminum Super Air Knife, for instance, weighs about 8lbs. The 36” Aluminum Full Flow Air Knife weighs less than 4lbs. Most of the time, 8lbs is a very manageable amount of mass to support, but there are situations where every ounce matters, and if yours is one of them, you’re looking at the Full Flow Air Knife all the way.

*The biggest (in the most literal sense) factor in Air Knife selection is, well…size. We make the Standard Air Knives in lengths to 48”, and the Full Flow Air Knives come as long as 36”. The Super Air Knives, however, are stocked in lengths from 3” to 108”, and can be coupled together for as long of an uninterrupted, steady, laminar air flow as you need.

At the end of the day, a majority of blow off applications can be handled just fine with any of our Air Knives. If you’d like to discuss your application and see which one is best for you, give us a call.

Air Conveyor Improves Candy Bar Recovery

This week I worked with a candy company who was looking to improve their overflow product recovery. When their bulk bagging machine is inoperable, the wrapped candy bars are sent to an overflow container where they are manually scooped out by an operator. This process was causing damage to the bars and wrappers, as well as presenting an ergonomic hazard to the employee, so they called EXAIR for a solution.

I recommended using our Line Vac Air Operated Conveyor. The Line Vac  connects to hose or pipe to create an inline conveyor and is able to move large amounts of material over long distances, requires no electricity, has no moving parts, and provides maintenance free operation, making it the ideal choice for this application.

After discussing the details with the customer, they were concerned that the candy bars and wrappers, getting picked up by the airflow and transported through the hose, might continue to be damaged. I advised that by using a pressure regulator they could control the vacuum/conveying rate by increasing or decreasing the supply pressure, but their concern remained. I then offered to perform a conveyance test at our facility, if they were willing to send product. The customer agreed and was kind enough to send some of the candy, with some extra bags inside for the staff here at EXAIR. (Which is pretty awesome! I mean, FREE candy? Who doesn’t love that?!)

With a wide range of sizes and materials of construction, we've got your solution.  Call us.

Available in 11 sizes and different materials to meet many application requirements. Line Vacs have smooth ends for connecting hose with a clamp or threaded ends to connect with standard pipe sizes.

Our set up included our 3″ Line Vac with a 10′ section of 3” conveyance hose on the vacuum side and a horizontal conveyance run of approximately 35′, with a 13′ vertical run into a soft sided hopper. We were successful in conveying approximately 9.9 lbs. per minute, when operating at 80 PSIG, with no broken candy bars and no damage to the wrappers. We also determined that 40 PSIG inlet pressure was the lowest they could run the operation, if they were okay with a lower convey rate.

We provided the results to the customer and included a short video of our testing. Intrigued by the results, they are now looking in to other possible applications throughout their facility.

To discuss your Line Vac application, please do not hesitate to contact us for assistance.

Heavy Duty Line Vac for Blasting Media Recovery

hdlv

Many times we will get the call from customers who are in the media blasting industry. Media blasting is used in many cases to clean or strip debris, residue, paint or other contamination from the surface of a variety of parts. This cleaning process is generally used to prepare a surface to receive further preparations or perhaps even a coat of primer or paint.

The media blasting process works very well. The only downside is that once the media is spent through the nozzle, it bounces off the part and lands on the ground or any other horizontal surface in the blasting room. So, clean-up after a session of blasting can become a real headache for the operators. Generally, they will want to recover the media for re-use as it can be quite expensive to purchase.

That’s where EXAIR comes in with our Heavy Duty Line Vac product. The Heavy Duty Line Vac has exceptionally high suction capability to move even the densest of blasting media back up into the supply hopper so it can be run through the system over and over. The highly abrasion resistant material of the Heavy Duty Line Vac has been tested with aggressive media such as ground glass and ground garnet and has a proven record of tolerance for moving such material without excessive wear. Other materials of construction like aluminum, stainless steel or hard anodized coatings will wear and degrade – the hardened alloy of the Heavy Duty Line Vac is the best choice for abrasive materials. 

Normally, customers in this industry will opt for the 1-1/2” or 2” model of our Heavy Duty Line Vac for their post blasting clean-up processes. It really takes a task that is true drudgery and turns it into a simple task. It takes the pain away for sure.

If you are in the blasting industry and have similar issues, we invite you to contact us and ask about the Heavy Duty Line Vac range of products. You will be glad you did.
