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

Published on by Russ BowmanLeave a comment

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

Published on by Russ BowmanLeave a comment

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 95°F (35°C) 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 125°F to 200°F (52°C to 93°C).
  • 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 “ATmosphères 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.

Save Money With Engineered Products, Then Save More Money With Rebates

Published on by Russ BowmanLeave a comment

One morning last summer, I turned on the water in the shower and waited for it to warm up. And waited…and waited. It was clear something was wrong, so I checked the water heater to find it emptying its contents into the floor drain, through the bottom of the tank, which I found later had rusted away. Between my better-than-average plumbing skills, having a son home from college, and finding out I could keep about $800 in my pocket if I bought a new one and replaced it myself, I woke the boy up (which turned out to be one of the more difficult tasks in the process), drove to my friendly neighborhood home improvement center, and bought myself a new water heater, and we had hot water by the time my wife got home from work that afternoon. Considering the way it started, it turned out to be a pretty good day. Not only was it more efficient (and therefore cheaper to run) than the one I replaced, the water heater I bought also qualified for a rebate, which increased my savings on the project to almost $900. That was some FANTASTIC icing on an already pretty decent cake.

Rewards like this for being energy conscious have been routinely offered by utility companies for years now. One time, I got a box of LED light bulbs, enough weather stripping for TWO houses the size of mine, and water-conserving shower heads, for free, from my electric company as part of a home energy audit. That was a pretty good day too.

Many utility companies across the country have similar programs for residential customers, and commercial ones too. Duke Energy (my free light bulb folks), for example, has a program they call Smart$aver that offers rebates and other incentives to companies for making energy-efficient improvements. Equipment that qualifies for these incentives includes process pumping systems, insulation for injection molding machinery & pellet dryer ducts, low friction v-belts for rotating machinery, and compressed air equipment.

That last one is what I wanted to write about today. It includes improvements to the supply side:

  • Receiver tanks
  • Cycling air dryers
  • Zero-loss condensate drains
  • Compressed air system audits

And the demand side:

EXAIR can help you out with the ones on the demand side. Consider:

Ultrasonic Leak Detector: this handheld device allows you to quickly & easily find leaks in your compressed air system.

EXAIR Model 9207 Ultrasonic Leak Detector filters out audible sound waves and focuses on the ultrasonic sound generated when compressed air finds its way out of a loose fitting, crack, etc. The parabolic disc (left) lets you find the area of the leak(s) and the tube extension (right) directs you to the precise location.
The copper tube used to have a crimped end that was aimed at the part in the chuck. They simply cut it off and used a compression fitting to install the Super Air Nozzle.

Super Air Nozzles: not only will these products get you a rebate, they’ll cost less to operate and will ensure OSHA compliance with regard to your use of compressed air. And they’ll do it quieter, to boot.

Replacing open-ended blow offs with Super Air Nozzles is oftentimes quick and easy. Compression fittings can be used to install them directly onto the ends of existing copper tubing. Stay Set Hoses can replace modular hose, which is great for machine tool coolant delivery but often misapplied for air blowing.

And frankly, I think the engineered products just look better too.

The Duke Energy Smart$aver program is for their customers in North Carolina, South Carolina, Indiana, Ohio, and Kentucky. If that’s not you, though, North Carolina State University’s NC Clean Energy Technology Center has a comprehensive Database of State Incentives for Renewables & Efficiency – DSIRE – that’ll help you find what’s available in your area.

Compressed air isn’t free. Heck, it isn’t even cheap. If you want to find out how much you can save by optimizing your compressed air system in Six Steps, give me a call. And if you want to sweeten the deal with rebates and incentives, contact your local utility company.

Compressed Air Use in the Construction Industry

Published on by Russ BowmanLeave a comment

My drive to work involves passing through a growing neighborhood in the northeast suburbs of Cincinnati, Ohio. Over the past few weeks, I’ve seen a wooded lot get cleared & graded for construction of a new house. A week or so ago, heavy earth-moving equipment was digging the basement foundation…and adding to the traffic as huge dump trucks carried the dirt away. Fast-forward to this morning, when I saw that the 2×4 framing of the walls and the placement of the roof joists were almost complete. The backhoes and dump trucks on the lot have been replaced by a small fleet of carpenter’s work trucks, a ‘porta-potty’ (a real plus, considering the number of workers spending 8–10 hours a day on a site that was the utility equivalent of a primitive campsite)…and an air compressor.

Compressed air has been used in construction since ancient times, when manually operated bellows devices were used to stoke fires to increase the temperature inside furnaces that were used to make metal tools and building materials. The first large scale industrial use of compressed air on a construction project was the building of the Mt. Cenis tunnel in Switzerland. Tunnel construction began in 1857 and was expected to take at least 25 years, with some estimates projecting a timeline of over 70 years. However, technical innovations – like the development of pneumatic drills that replaced steam-operated machinery – allowed them to complete it in only 14 years.

In addition to the pneumatic nail guns and impact drivers being used at the new home site along my daily commute, compressed air has a number of other uses in the construction trades. It’s used for excavation, to power de-watering & sludge pumps, hoists, and even material conveyors. For example, a contractor that was building a large fence on sandy terrain used a Model 150200 2″ Heavy Duty Line Vac to remove sand from the hollow fence posts after using hammer drills (which are also air operated, so you know) to anchor them in place. Another user got a Model 151250 2-1/2 NPT Threaded Heavy Duty Line Vac to remove light dirt & sand from holes they dig to set posts in. Both power their Line Vacs with diesel-fueled 185 CFM tow-behind compressors.

Heavy Duty Line Vac: Hardened Alloy Construction and High Performance

EXAIR Air Knives are also used by construction companies. One of our customers bought a Model 110218 18″ Aluminum Super Air Knife Kit to blow an air curtain onto a conveyor to separate filter fabric out of recycled asphalt. Many lumber & building material manufacturers use them to blow off sawdust and loose debris from plywood, OSB board, roofing shingles, etc.

Top: 108″ Super Air Knife is supported & aimed via an array of Model 9060 Universal Air Knife Mounting Systems.
Bottom: Mounting Systems can be ‘overkill’ for some smaller applications, especially when the user is creative. Yes, that’s a door hinge. No, it wasn’t my idea, but I kind of wish it was.

Another customer uses a Model 6901 Spill Recovery Kit with their Model 6395 55 Gallon Premium High Lift Reversible Drum Vac System for cleaning up spills of hydraulic oil from their equipment at construction job sites. The ability to vacuum it up without dragging an electric cord from a shop vac through the puddles of oil is a real plus for them.

The EXAIR Reversible Drum Vac System converts a drum and dolly into a mobile pumping system.

And back to the Line Vacs, an electrical contractor uses a Model 6086 3″ Aluminum Line Vac to pull wire through stretches of underground conduit that are too long for standard fish tapes. They can pull the fish line through 120 feet of conduit in about 30 seconds. The Line Vac also removes any debris that might have accumulated inside the conduit between installation and wire pulling.

If you’re in the construction industry – or any industry, really – and would like to discuss a potential application for engineered compressed air products, give me a call.
