O-Rings, Seals, Gaskets, Maintenace, Filtration – They All Matter

I’ve mentioned it before and I’ll say it again. You can’t teach experience. This was told to me by a mentor at a previous job and of course, younger me thought, “Yeah, yeah I know all I need to know.”  Well, younger me was an idiot and learned many things through experience. Sometimes I am still a slow learner and eventually, I remember those experiences and make decisions based on them. So what does this have to do with o-rings, seals, and gaskets?

I’m in the midst of a light construction project in my house and have reached a stage where some tools that I do not have would come in handy and make the job faster. Younger me would have justified purchasing a new one, experienced me understands a budget and reached out to my network of friends and a good friend said they had the tool I needed. This was a compressed air powered framing nail gun. Straight through nailing, no-problem, toe-nailing, no-problem, this thing won’t break a sweat and your arms will be stronger by the time you are done using it while your thumbs are screaming thank you for not smashing me a hundred times.

The Framing Nail Gun in question

This loan did come with two conditions, one was, he didn’t have any nails to give with it. This was not a problem as I wouldn’t expect a friend to give me free fasteners with a tool loan. The second is the one that concerned me, he said, it does leak a little air but it should still shoot just fine. After working in the compressed air industry for over a decade I have experienced this many times. At that point I knew if you could hear it, chances were it was a bad leak. Upon further inspection, there was a cylinder gasket and rubber spring that were in pieces.

Gasket pieces and dirty air can result in catastrophic failures.

Nothing that a trip to a local business couldn’t take care of.  A few new parts and discussion with their knowledgeable staff and I had the information needed to rebuild this nail gun to functioning status.

New vs. Old

Oddly enough, my experience and expertise with how the EXAIR products like the No-Drip Air Atomizing Liquid Spray Nozzles operate and how to rebuild them, provided a good foundation about how this tool worked. This repair ended up being very similar to the rebuild on a No-Drip Spray Nozzle.

This story is two-fold, filtration could have prevented a lot of the damage to this gun. This gun uses a good amount of air volume at an expedient pace so keeping it clean and clear of debris helps extend the lifetime of internal parts.  See my video on what happens without filtration below.

The second part is that maintaining and understanding processes to clean/rebuild are crucial to sustainable function of a machine. The cleaning process for this gun was fairly straightforward and using the correct lubricant for reassembly was another critical role. This culminated in a framing nail gun that can now be used to further my project and will more than likely live another decade before needing a rebuild again. That is if filtration and proper lubrication are followed.

Had I not obtained experiences throughout my career that helped me to understand how this tool functioned, the worth of a reliable network of vendors, and the necessity to complete tasks that take me out of my comfort zone I wouldn’t be in the place I am today. Because I have the experience and the network to ask for help it enables me to keep machines running that could have cost valuable production hours had this been a production environment.

EXAIR stocks rebuild kits, gaskets, shims, and parts for all of our product lines which may require a repair. For products which need to be cleaned in order to return back to new performance, we have the instructions or can do it for you here. From time to time they may need a repair or refurb in order to keep functioning at peak performance. If you want to build your trusted network or learn more about how to rebuild or clean EXAIR products, contact us.

EXAIR Cabinet Coolers Nominated for Product of the Year

We have just found out that four of our new problem solving products have been nominated for Plant Engineering’s Product of the Year (Please Vote for us HERE).  The first candidate I would like to showcase is in the Automation & Controls category.  The Electronic Temperature Control for Dual Cabinet Cooler Systems effectively turn the compressed air supply to the Cabinet Coolers on and off as needed to maintain a constant temperature inside of a hot enclosure. Using the air intermittently to maintain a specific temperature is the most efficient way to operate.

Please Vote!
Please Vote!

The ETC Dual Cabinet Cooler Systems work in conjunction with EXAIR’s UL listed Cabinet Cooler Systems which provide cooling for your electrical enclosures without the use of refrigerant based coolants or fans.   The Cabinet Cooler Systems utilize a compressed air driven Vortex Tube which uses compressed air. This cold compressed air is exhausted into the enclosure which results in a cool working environment for your electronics. Warm air from inside the enclosure is vented safely back out of the cabinet through built in exhausts and the compressed air is only utilized when the internal air temperature reaches the digitally set temperature on the ETC.

Another added benefit of the ETC on the Cabinet Cooler system is the real time readout of the internal air temperature of your enclosures.  This is on top of the push button set point which will give you a +/-2°F ambient temperature inside of your enclosure.

The ETC Dual Cabinet Cooler Systems are designed for larger heat loads ranging from 3,400 BTU/hr. to 5,600 BTU/hr.   The units are available in NEMA 12, NEMA 4, and NEMA 4X ratings.   This means whether you are in a fairly clean environment or a dirty, hot, muggy environment, EXAIR has you covered.

If you would like to discuss either the ETC or the Cabinet Cooler Systems, please contact an Application Engineer.   If you would like to vote for our products, please check out the Plant Engineering Product of the Year page here.

Line Vac Assists Pump Bottle Assembling

We have a customer in the packaging industry who packages liquid soap into bottles. Part of the process involves loading the push-pump dispenser into a capping machine to be assembled to the bottle after filling.

The problem was that the push-pumps came in cardboard boxes which had to be wheeled over to the machine and dumped into the hopper. This was rather difficult as the top of the hopper on the capping machine was over eight feet off the ground. So, the customer went looking for some sort of solution to suck the pumps up out of the box and into his hopper.

Fortunately, he found EXAIR Corporation and our Line Vac product. We discussed the rate at which he needed to convey the product, the distance and the dimensions of the parts. All was well suited for the 4” Aluminum Line Vac Model 6086. The customer tried a few different configurations with the Line Vac and his hose because manipulating a 4” hose around isn’t all that easy to do. So the customer came up with an ingenious little waist-high platform with the vacuum feed on one side into which the parts could be slid into and vacuumed up to the hopper.

The customer is going to evaluate the effectiveness for this method of loading. He was planning on a time savings of at least 10 minutes per box to fill the hopper. He is also banking on the fact that it is now a safer application because an operator no longer has to climb a ladder to fill the hopper.

Are you in the packaging industry? Do you have an odd-shaped product that you could use to move from point A to point B rather quickly?  Perhaps you have a hopper that needs to be filled? Give one of our Application Engineers a call today to discuss your application.
