More And More Award Winning Products From EXAIR

As you might expect, a LOT of things have changed at EXAIR Corporation since 1983. Most of our current senior management had yet to graduate high school, and a fair number of current employees had yet to BE BORN. According to our computer system (another BIG change since 1983), our first ten customers were here in southwest Ohio (#11 was in Michigan), and now, we sell direct across the US & Canada, and our worldwide distributor network offers representation on six continents. One thing that hasn’t changed, though, is our founder’s vision of manufacturing quiet, safe, & efficient compressed air products for process improvement in just about any industry that uses compressed air. And THAT, dear reader, continues to gain high profile attention. The photo above shows the seven awards that our products have recently won, which were announced in 2021 or early 2022. Here’s a rundown:

Plant Engineering 2020 Product of the Year (Fluid Handling) GOLD AWARD:

  • A medical device manufacturer has one in a Class 7 clean room for silicone parts cleanliness.
  • A nutritional supplements maker uses their Intellistat® to remove static charge & powder residue from the tops of plastic bags before sealing them. The excess/residual powder causes them not to seal correctly.

Machine Design 2021 Big Idea! (Electrical Components) BRONZE AWARD
Gen4® Static Eliminator Power Supply

All EXAIR Gen4 Static Eliminators use one of two Power Supplies – your choice of the 2-port Model 7960, or the 4-port Model 7961.

EXAIR Static Eliminators produce ionized air via a Corona discharge, which requires high voltage, low current electricity. The Gen4® Static Eliminator Products feature armored & shielded cables with an internal ground, for safety and reliability. The ground path is completed through the cable and the Power Supply port, eliminating the need for an external ground connection. Faults in external ground connections result in the majority of the problems with those devices, so the internal ground is a “Big Idea!” indeed. The Gen4® Static Eliminator Power Supplies are switchable for 115VAC or 230VAC voltages, and are offered in 2, or 4 outlet designs, which can power any 2, or 4 EXAIR Static Eliminator Products. Like most EXAIR Intelligent Compressed Air Products, they’re used for a wide range of applications, in a wide range of industries:

Pneumatics: Top 10 Advantages of EXAIR Compressed Air Products

Pneumatics is a branch of engineering that makes use of gas or compressed air. The word pneumatic is derived from the Greek words πνεῦμα pneuma and means wind breath. With 9 out of 10 industries utilizing compressed air products and processes, we could say that pneumatics are the “breath” of industry. OK, I may be stretching here, but it it does flow well…

At EXAIR, we pride ourselves on using compressed air intelligently. Nearly all of our products utilize compressed air and maximize it’s efficiency. Let’s take a deep breath and look at some of the reasons why “wind breath”, and more importantly why the EXAIR products are so advantageous in industry.

REASONS TO USE COMPRESSED AIR

PNEUMATICS

  1. There is an infinite supply of air on this planet to be compressed and used. I know this seems obvious but what other energy source has an infinite supply?
  2. There are very low maintenance costs with pneumatic tools. Our products have minimal to no moving parts. There is no motor to repair, no oil to change, no bearings or fans.
  3. Our products are engineered to be easily installed and can be adjusted for performance. Most of the time you simply mount the product and add air. A simple pressure regulator provides a huge bandwidth of adjustment to dial in the force and performance.
  4. Air is very easy to transport. With your current compressor system, you can easily run pipe to the point of use and supply the products with their power source.
  5. Compressed air is compact, and usually takes up less space to install a compressed air product.
  6. Our products and tools are extremely reliable. Due to the precision engineering and production, our products produce a repeatable result every time they are turned on.
  7. EXAIR products all comply with OSHA standards for sound (29 CFR 1910-242 (b)) as well as dead end pressure 29 CFR-1910.95(a)).
  8. Initial purchase as well as installation costs are typically considerably lower than non pneumatic options. When you add in the upkeep and maintenance, EXAIR products are almost always less expensive than alternative products.
  9. Using compressed air as your power supply typically facilitates a cleaner, dryer, safer work environment.
  10. At EXAIR, you have a team of application engineers at your fingertips that will help you choose the best product for your specific application. Feel free to call or email at anytime.

Compressed air Storage: Do you need a Receiver Tank?

Maintaining a “supply and demand” balance in the design & operation of compressed air systems often includes receiver tanks.

Just like in economics, we have to consider both sides – supply AND demand – to best maintain this balance.  Also like in economics, there are numerous factors…on both sides…but the two most critical factors are:

  • Compressor capacity control (supply side)
  • System storage (demand side)

I wrote a blog on “Air Compressor Motors and Controls, Working Together”, outlining the ‘supply side’ variables, today lets look at the system storage. Distribution piping makes up a certain amount of this, and another great blog from my colleague, Tyler Daniel – “Intelligent Compressed Air: Distribution Piping and Pressure Drop” – gets me off the hook for THAT part of the discussion today.

We can consider the air capacity of system piping to be fixed for the purposes of this discussion, so our “variable” will be the capacity of storage tanks. Let’s start with the reasons for the need for system storage: Strategically placed point-of-use air receivers provide stored energy for intermittent demands.  This enables the compressed air system to handle fluctuating loads, efficiently & reliably.  It also minimizes impact (e.g., sudden and often detrimental drops) on the system pressure.

Next, we’ll look at location. There are a couple of common options to consider:

  • The intermittent demand. Installing a receiver here will provide enough air for short duration, high consumption events, protecting the rest of the system from pressure excursions. Dedicating the receiver to this application will mean isolating it from the rest of the system with a check valve (so it only supplies the load in question) and a needle valve (so recharging the receiver itself, between the intermittent uses, doesn’t adversely affect total system pressure).
  • The critical load(s). Instead of using stored air for the intermittent load, you can also use it for the important loads you’re trying to protect. All sorts of machinery with pneumatic components can “crash” if a nearby intermittent demand starts up & “steals” their air. You’ll use a check valve (same as above), but using a needle valve to throttle the air flow that recharges the receiver risks “starving” the critical load. Don’t do that unless there’s a really good (and likely really specific) reason for it.

Finally, we’re going to do some math, so we know how big this receiver has to be. Here’s the equation we use to do that:

Let’s calculate the receiver size needed to supply an intermittent load of 400 SCFM (C) @80psig (P2), that’ll run for one minute (T). You can use data specific to your system to come up with a value for (Cap) but here I’m going to assume we want the receiver to be able to handle the whole thing, so Cap = 0. I’m also going to assume we’re at sea level, so Pa = 14.7psia and that our compressor’s discharge pressure (the pressure at which the receiver can be charged to) is 120psig (P1):

That’s an awfully big tank. Now, let’s calculate the receiver size needed to protect a critical load that uses 55 SCFM @60psig, and that due to the system design, we can count on 25 SCFM @120psig from the compressor:

This is a much more manageable size, in fact, our 60 Gallon Receiver Tank (Model 9500-60) would be ideal. It’s 20″ in diameter and just over 50″ tall, so it doesn’t take up a lot of floor space. It comes with a drain valve and connections for compressed air flow in & out, pressure gauge, relief valve, etc.

Step Five of our Six Steps To Optimizing Your Compressed Air System: Use intermediate storage near the point of use.

Now, the above example is a completely hypothetical situation, and I purposely chose exaggerated values to show that there can indeed be a clear “winner” in the choice between the two installation points. If you have a situation like this, and would like help in finding the solution that makes the most sense, give us a call.
