Sometimes Plans Go Sideways – And Thatโ€™s Okay

I often write and share personal experiences here. Itโ€™s kind of funnyโ€”if you had asked me 15 years ago whether Iโ€™d be writing regularly, I would have said, โ€œAbsolutely not.โ€ That sentiment actually ties in well with todayโ€™s message.

Last night, I decided to tackle a maintenance issue on a 2014 Honda Pilot that’d been graciously loaned to us while we saved up for a newer vehicle for my wife. Her vanโ€™s transmission failed, and the cost to repair it just didnโ€™t make sense. The Pilot has had a persistent clunking noise whenever it hits a bump. Upon inspection, I found both sway bar links were completely shotโ€”the grease boots were torn, and the sway bar bushings were totally rotted. I had ordered the parts last winter with a few others, and I finally had time in my schedule to take care of them.

If youโ€™ve ever worked on sway bar links, you know they usually donโ€™t come off easily. Still, I kept a positive mindset and tried to remove the nuts holding the links in placeโ€”with zero success. So, out came the saw. I was able to cut the driver-side link out, and thatโ€™s when I shouldโ€™ve realized things wouldnโ€™t go smoothly.

My cut on the lower bolt was off and left too much of the stud. So, I grabbed another tool: the angle grinder. Iโ€™m not afraid to use the right toolโ€”or to get rough when needed. With the sway bar supported and my hearing protection on, I went to work. It wasnโ€™t a perfect job, but eventually I used a punch and hammer to knock out the remnants and moved on to the top mount. That one backed off halfway, then got cut at the threads and came right out. Thank goodness for sharp saw blades.

With the old link gone, I removed the deteriorated bushing and installed the new one without any trouble. Then came time to install the new sway bar link. These replacements were serviceable with grease fittingsโ€”a nice little upgrade for this older vehicleโ€”so I had a good feeling theyโ€™d be the last ones it would ever need.

Oddly, the two new links (bought at the same time) came with different styles of lock nuts. One was slightly smashed into an oblong shape. The top nut went on snugly, but just as I was torquing it down, the Allen key recess began to round out. Not a huge deal, since I didnโ€™t anticipate needing to take them apart again.

But the bottom stud and oblong retaining nut didnโ€™t go so well. Halfway on, the nut tightened up severely, and the hex recess rounded out. All I could think was, โ€œIt shouldnโ€™t be this hard.โ€ I used the small wrench that came with the new links, and it popped looseโ€”finally. Then I resorted to using vise grips on the flats.

Hereโ€™s where I made my mistake: I didnโ€™t slide the grease boot out of the way and kept going. Just as I reached the last thread, the pliers slipped and pinched the brand-new grease boot. I still finished the installationโ€”knowing Iโ€™d have to remove it again anywayโ€”and wanted to make sure nothing else was out of alignment. At the time, I felt defeated by a simple task. This really shouldn’t have been so difficult.

In the end, I ordered another new sway bar link. Itโ€™s on the way, and Iโ€™ll attempt round two in 3โ€“5 business days.

So, whatโ€™s the point of this story? Things donโ€™t always go as planned. Sometimes it’s because you miss something or donโ€™t trust your gut when something feels off. Other times, itโ€™s stubborn determination to force something that just isnโ€™t working. You can either dwell on it or take a breath, make a new plan, and keep pushing forward with the same energy.

Iโ€™ve seen this play out not just in car repairs, but in travel, my career, and life in general. When something doesn’t go right, it’s okay. Just adjust and move forward. Itโ€™s a mindset we bring to our work with customers at EXAIR.

Thatโ€™s why our 30-day guarantee matters so much. If a recommendation didnโ€™t work out, or testing pointed in one direction, but the results just werenโ€™t there, weโ€™ll help you rework the plan. Weโ€™ll back whatโ€™s already been done by covering any stock product with our 30-day guarantee and help chart a new path forward.

Weโ€™re not perfect, and we never claim to be. My plans donโ€™t always work out either. But a failure doesnโ€™t mean the endโ€”it just means itโ€™s time for a new plan of attack.

Big shout-out to my youngest daughter for snapping the photo of the passenger side and spraying down the rusted studs with Aero Kroil while I was at work, and she was enjoying summer break. It definitely pays to have your kids pitch in on these projects.

Venturi Effect in Use

The Venturi effect describes the phenomenon where a fluid, such as air or water, accelerates as it passes through a constricted section, resulting in a decrease in pressure. This occurs because the fluid is drawn into the narrower area, and the increase in velocity leads to a corresponding drop in pressure. The effect is named after Giovanni Battista Venturi, who first articulated this principle in 1797.

A perfect example of the Venturi Effect can be found in our Air Amplifiers. Compressed air enters through the air inlet and flows into an annular chamber, where it is accelerated through a small ring nozzle. This high-velocity primary airstream follows the Coanda effect, guiding it toward the outlet. As a result, a low-pressure zone forms at the center, drawing in a significant volume of surrounding air into the primary flow. The mixture of the primary airstream and the surrounding air is then expelled from the Air Amplifier at a high volume and velocity.

The Venturi Effect is represented in amplification ratios. A ratio represents the relationship between two quantities, indicating how many times one value is contained within another. In the case of the Super Air Knife, this ratio illustrates the volume of ambient air that is drawn in alongside the primary flow of compressed air. With an impressive amplification ratio of 40:1, the Super Air Knife incorporates 40 parts of ambient air for every single part of compressed air, making it one of the most efficient air-operated knives available. This addition of mass enhances the device’s ability to deliver a powerful force, enabling it to perform more effectively in various applications.

The Venturi effect is integral to various EXAIR products designed for cooling, drying, and cleaning, alongside our vacuum generators. If your facility has a process that could benefit from an Intelligent Compressed Air solution, please reach out to us. We would be pleased to discuss your specific application and develop a solution that not only lowers your compressed air expenses but also enhances worker safety.

Using EXAIR Products for “The Old One-Two Punch”

In boxing, there are five basic punches, and they’re commonly called out by numbers so that trainers can instruct boxers rapidly during the development of fundamentals. It’s also useful for them in real live bouts, where overly complicated plans can lead to defeat….former heavyweight champion Mike Tyson famously said, “everyone has a plan until they get punched in the mouth.” Those five basic punches are:

  • #1: The jab. Just like it sounds, this is a punch thrown directly forward with the lead hand. In many combinations, it’s the first punch thrown (that’s why it’s #1).
  • #2: The cross. This is a more powerful punch thrown with the back, or dominant, hand, and gets its power from the torque & rotation of the boxer’s body, when thrown correctly.
  • #3: The lead hook. This is an even more powerful punch than the cross. Its power comes not only from rotating the torso (like the cross) but also by pivoting on the lead foot to get the hip & shoulder involved. Because of the unbalanced and relatively unguarded position it leaves the boxer in, it’s riskier than a jab or cross, and oftentimes reserved for situations where the boxer sees an opportunity to score a knockout blow. If that plan doesn’t work, Mike Tyson’s famous quote above may very well come to fruition.
  • #4: The right uppercut. This is another devastating punch, thrown by the boxer’s dominant hand (assuming they’re right-handed) in an upward motion to contact the opponent’s head or body. If it connects to the chin or solar plexus, there’s a good chance the opponent will end up on the mat. It has to be thrown while the boxer is in close with the opponent, which gives the opponent the option to deal a devastating blow as well.
  • #5: The left uppercut. Same as above, but thrown with the boxer’s lead, or less dominant hand (again, assuming they’re right-handed.)

Because it generally leaves the boxer in a better defense position, the “one-two” combination is by far one of the most used moves in the ring. The term has even found its way into the popular vernacular, meaning two things that happen in rapid succession that lead to the desired outcome.

For the purposes of today’s blog (as the title suggests), I’m going to use it to describe an application where a customer uses two EXAIR products: a Model 1006SS Back Blow Air Nozzle, and a Model 6082 1″ Aluminum Line Vac in conjunction with each other.

This particular customer uses the Back Blow Air Nozzle to blow out the injector bore of an engine cylinder head assembly.

EXAIR manufactures three sizes of Back Blow Nozzles: our Model 1008SS Atto Back Blow Air Nozzle (left) is 0.2″ in diameter and can be used in 1/4″ to 1″ inside diameter holes, channels, etc. Model 11006SS 1/4 NPT Back Blow Air Nozzle (center) is good for 7/8″ to 4″ inside diameters, and Model 1008SS 1 NPT Back Blow Air Nozzle (right) is used for 2″ to 16″ inside diameters.

Thing is, they don’t want the debris flying all over the place. We considered a Chip Shield on the 1/4″ pipe extension that the Back Blow Air Nozzle was threaded onto, but since they insert it vertically from above, that could allow for debris to fall back down onto the assembly, and possibly right back into the injector bore, or one of the other openings on top. Instead, they opted for a Line Vac to vacuum the debris away as the Back Blow Air Nozzle blew it out of the hole.

While Line Vacs are primarily used to convey bulk material from one place to another (left), or to remove scrap trim (center), they’re also well suited for this application. Compressed air (1) enters the annular plenum (2) and is ejected at a high velocity through a ring of jets (3). This draws a vacuum on the inlet (4), creating a conveyance flow of air to carry whatever’s entrained in that flow through the outlet (5).

Engineered compressed air products have a multitude of advantages in applications like this. They’re durable & reliable. They have no moving parts to wear, or electrical components to burn out. They can operate continuously if needed, or they can be cycled on & off rapidly with no ill effects. If you’d like to find out how EXAIR Intelligent Compressed Air Products can help your operation, give me a call.

New Press Release: Aluminum ATEX Cabinet Cooler Systems

EXAIR Cabinet Cooler Systems have been providing durable and reliable heat protection for electrical & electronic panels for decades. With no moving parts to wear or electrical components to burn out, as long as you supply them with clean, moisture-free compressed air, they’ll operate darn near indefinitely, maintenance free.

From right to left: Small NEMA 12, Large NEMA 12, Large NEMA 4X

Among the options we’ve offered with our Cabinet Cooler Systems are:

  • Three levels of NEMA integrity to suit the environment it’ll be installed in:
    • NEMA 12 (dust tight, oil tight, indoor duty)-for general industrial environments where no liquids or corrosives are present.
    • NEMA 4 (dust-tight, oil-tight, splash-resistant, indoor/outdoor duty)-for wash down areas, outdoor installations, etc. Basically, anywhere the panel could get wet.
    • NEMA 4X (dust-tight, oil-tight, splash-resistant, corrosion-resistant, indoor/outdoor duty)-for NEMA 4 environments where the panel is also exposed to corrosive elements. These are also popular (and oftentimes specified) in food and pharmaceutical uses. We offer them in either 303SS or 316SS.
  • Thermostat Control:
    • Our standard offering is a bimetallic probe thermostat, preset to 95ยฐF (35ยฐC) that gets wired in to the ‘hot’ lead of the Solenoid Valve, which gets plumbed to the compressed air supply line. We have 120VAC, 240VAC, and 24VDC Solenoid Valves.
    • ETC Electronic Temperature Control is a digital system with an LED readout for continuous display of the panel’s internal temperature, and the ability to change the temperature setpoint via push button control. ETC systems come in 120VAC and 240VAC configurations.
  • High Temperature Cabinet Cooler Systems. These are rated for use at ambient temperatures from 125ยฐF to 200ยฐF (52ยฐC to 93ยฐC).
  • Non-Hazardous Purge (NHP) Systems. These are Thermostat controlled, but they provide a slight positive pressure in the enclosure even when the Solenoid Valve is closed. They’re particularly well-suited for dirty environments where contamination could enter through small holes, conduits, etc. that cannot be positively sealed.

Over the last few years, we’ve also offered the NEMA 4 & 4X Cabinet Cooler Systems for UL Classified areas. Our HazLoc Cabinet Cooler Systems are rated for Class I Div 1, Class II Div 1, and Class III areas, and they meet the safety standards published by UL in the United States and Canada.

Our latest offering for hazardous locations is our ATEX Cabinet Cooler Systems. ATEX (an initialization of the French term “ATmosphรจres EXplosives” (explosive atmospheres) refers to a directive by the European Union aimed at safety in such environments. This month’s EXAIR Press Release details our Aluminum ATEX Cabinet Cooler Systems:


NEMA 4 ATEX Cabinet Cooler System safely cools a panel in a Zone 2 (explosive vapor) area of a battery plant.
