Maintenance Free And Proud Of It

Caller: Do you sell rebuild kits?
Me: Yes, but…why?

This is a WAY oversimplified summary of the start of a popular conversation that an EXAIR Application Engineer might have with a caller looking to restore a particular product to proper operation. Truth is, most of our products have no moving parts, and if you supply them with clean, dry air, they’ll run maintenance free, darn near indefinitely. We’ve documented this in specific cases regarding a Reversible Drum Vac from 1999, a Vortex Tube from 1987, and a Cold Gun from 1985.

Product & year of manufacture, from top left: Reversible Drum Vac (1999,) Cold Gun (1985,) Vortex Tube (1987.) All still performing within factory specifications.

Caller: So…DO you sell rebuild kits?
Me: Yes, but…only when necessary.

It’s important to note that none of the products mentioned above needed any parts replaced to return to service. Sometimes, a good cleaning is all that’s required. We can help you with a video tutorial if you want to know how to restore a Reversible Drum Vac, an Air Knife, or an Atomizing Spray Nozzle, for instance.  And we’re making new videos all the time for product maintenance, operation, tips & tricks, etc.

Caller (again): So…you DO sell rebuild kits?
Me: Yes, of course!  I mean, who wouldn’t sell rebuild kits for their products?

Take our Safety Air Guns, for example. We offer Service Kits, if the trigger and/or internal valve of a Soft Grip or Heavy Duty Safety Air Gun starts to wear or leak, it’s super easy to replace. We’ve also got replacement springs for the “fail shut” feature of the ball valve of a Super Blast Safety Air Gun. Just about anything else that could be wrong with a Safety Air Gun’s performance can be addressed by cleaning the nozzle.

We also recently added Rebuild Kits for our Atomizing Spray Nozzles to inventory. These contain all of the seals (and moving parts, for the No-Drip models) to restore an EXAIR Spray Nozzle to rated performance.

Keep your EXAIR Atomizing Spray Nozzle (left) in perfect working order with a simple & inexpensive Rebuilt Kit (right of the nozzle.) Contact an Application Engineer to select the one for your product.

For other products, we can also provide replacement gaskets & seals for the Reversible Drum Vac & Chip Trapper products, O-rings for the Line Vacs, Chip Vacs, and Heavy Duty Dry Vacs, new elements for Filter Separators & Oil Removal Filters…just to name a few.

Bottom line: if your EXAIR product isn’t performing the way it used to, give me a call.  It will be my pleasure to help you get it working like new, so that you can continue to get the most out of it.

Step by Step Guide – Choosing Atomizing Spray Nozzles

EB1040SS

Atomizing spray nozzles atomize fluids to create a fine spray in a variety of patterns for a variety of uses. They are commonly used to mark products, paint or coat, cool, reduce dust, lubricate and clean parts.

With the numerous types of Atomizing Nozzles sold by EXAIR, it can be challenging to shift through all the information. We can help you to narrow down the field to quickly find the correct Atomizing Nozzle for your application.  In a summary, here are the basic questions that need to be answered:

1.) Are you using a pressurized liquid feed?

2.) What is the viscosity of the fluid?

3.) What is the liquid feed rate in gallons per hour (gph) or liters per hour (lph).

4.)  Should I use the No-Drip option?

EXAIR’s flow chart with easy-to-follow steps will walk you through the decision tree and land you at the best Atomizing Spray Nozzle for your application. In answering these simple questions, this chart will guide you to the correct page in our current catalog to get additional information and specifications.    Click on Link below to determine the best nozzle for you.

Video Blog: Air Entrainment Of An Air Amplifier

The following is a short video explaining how EXAIR’s Super Air Amplifiers work. It also shows the high volume of surrounding air that is pulled into the outlet flow with a very small amount of compressed air required. As yo will see, this high volume of ambient air produces a dramatic effect on the Air Amplifier’s  outlet flow. Super Air Amplifiers are very efficient, quiet and safe and can be used to vent fumes, circulate air, cool, clean and blow off surfaces.

Air Knives – What Are They Good For?

It is rare that a week goes by without a unique application of an EXAIR product…

This week I was speaking with a DJ who wished to use an air knife to create a blast of air that would add emphasis to the musical experience had by his fans. He wanted a small burst of air that would last less than a second, but would add an additional element to an already very complicated setup. My initial reaction was that no DJ I have ever seen would possibly be able to supply an air compressor big enough to feed the air knives, but over the course of our conversation, I found out that the DJ travels with 2 semi trucks of equipment, so he had some space.

Another topic that came up in our conversation was how air knives were generally used. I have been asked this in a number of ways: What are they designed to do? Where do they work best? or What are they for?

I never have a succinct answer… The air knives create a flat laminar sheet of air in various sizes from 3″ up to 108″. This laminar sheet of air can be used to move, open, float, or separate. It can be used to clean, dry, or cool. I try to categorize these applications as best I can when speaking to customers, but then you talk to a DJ, and he wants an air knife to make a crowd cheer. I never thought that would be an application for an air knife. Knowing this, how do you convey all the air knife can do in a succinct answer?

Well, I can’t, so please be patient when you ask me the same question and I run through applications from cleaning surfaces to entertaining DJ crowds.

Here is a rundown of air knife applications. In case you don’t believe me.

Move: Air Knives are used around to world to move product from a conveyor to another location.

Open: Air Knives uniform air flow is perfect for opening bags or other packaging on a packaging machine.

Float: If you need to bridge a gap between two conveyors, the air knife has done this for products from pizza dough to sheets of veneer.

Clean: Blowing products off after removing them from a CNC machine is an easy air knife application.

Dry: One of my tastiest applications was to use an air knife to blow water from a potato chip after washing, but before frying.

Cool: Extrusion, molds, and baked goods have all been cooled with an air knife.

Just because it isn’t on this list though, doesn’t mean it is not possible.  This is why we will stand behind our stock product with our 30 day guarantee.   So if you want to try an EXAIR Air Knife in your application, give us a call.

EXAIR Safety Air Guns Quickly Remove Years Of Debris From Large Building’s Ceiling

The air gun is a quintessential tool found in a variety of settings. Machinists will use them to blow chips, debris, and coolant from parts as they’re being finished. They’re commonly used for final cleanup before an item is packaged…nobody wants to open up a brand new product and find dust, dirt, or dried-up coolant spots on it. They can make a quick job of cleaning off a work bench…if you intend to sweep the floor afterwards, that is. In fact, larger air guns can even be used to “sweep” the floor.

I recently had the pleasure of assisting a user who was going completely the other way…from the floor, that is. His company had been contracted by the new owners of a rather large show facility to “rehab” the building. Before they could do anything, though, he needed to clean years and years (and years, he said) of dust, sediment, cobwebs, and other various debris, from the open rafters overhead. All 42,000 square feet of overhead. And, because of their schedule for getting the facility ready for upcoming shows, it needed to be done quickly.

After discussing the application and comparing the capabilities of our various Safety Air Gun offerings to the available compressed air supply, I recommended, and they purchased, two Model 1360-48 Heavy Duty Safety Air Guns, fitted with Model 1106 High Force Super Air Nozzles. These made short work of a big part of the job, allowing them to move quickly on to the rest of the building restoration.

If you’ve got a cleanup job…big or small…perhaps an EXAIR Safety Air Gun is the solution. We’ve got them ranging from the Model 1408SS Precision Safety Air Gun, fitted with our 1108SS Atto Super Air Nozzle (2.5 SCFM; 2.0 ounces of force,) to the Model 1218-6 Super Blast Safety Air Gun, which uses our largest High Force Super Air Nozzle, the 1120 (460 SCFM, 23 pounds of force,) and 29 models in between. We can provide them with accessories such as Chip Shields, Stay Set Hoses, Rigid Pipe Extensions, and Compressed Air Hoses, as needed. Give me a call to find out which one is right for you.

Here are just 2 of our 53 distinct models of Safety Air Guns.  I bet we've got the one you're looking for.

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.
