Adjustable Vacuum Levels for Different Materials from These Vacuum Generators

When determining a single vacuum generator that will fit a variety of demands, whether it be varying weights, surface finishes or materials, the Adjustable E-Vacs can make quick work of the task at hand. This minimizes the number of parts needed for a variable product line. It also means each application can be adjustable as well. So why would this be needed?

Let’s look at a custom woodworking shop. They could be lifting slabs of lumber that may be rough cut, maybe they are lifting a smooth epoxy river slab, or even sheet of MDF. Each one of these materials will require some adjustment on the vacuum end. The reason being the surface finish and porosity of each material is considerably different.

MDF, expanded out as Medium Density Fiberboard is a common material for woodworkers to use. This material looks and feels smooth and fairly solid. The trick is, it is actually a porous material. You can hook a vacuum hose to one side of it and hold a piece of notebook paper to the other side because the vacuum flow will be pulling through the MDF. This presents a problem when trying to use vacuum to pick and place the board. You will need a higher vacuum flow in order to compensate for the leakage of air when pulling a vacuum. An epoxy coated slab on the other hand, is generally a smooth surface that is non-porous and will require less vacuum flow.

Adjustable E-Vac: How it works

The greatest benefit to the Adjustable E-Vac is being able to easily adapt to meet the needs for both of these materials with a tool-free adjustment. A great example of this is in the video below.

If you would like to discuss which of the Adjustable E-Vacs is right for your variable application, reach out an Application Engineer today. We can all help you determine which of the 4 Adjustable E-Vacs will best fit your application and even help you understand what kind of adjustments will need to be made.

INDIANA: Energy Rebates and EXAIR Save You Money On Top of Compressed Air Savings

The energy rebates described below are available throughout the country, not just Indiana – but here is the latest example.

Here in Cincinnati we border two states, our bypass loop actually goes through both of them, Kentucky and Indiana. Indiana is a state that most may fly over or if you are going anywhere it may be to go to Indianapolis, myself, I have a few ties to the state elsewhere, from racing motorcycles at Putnam Park west of Indy, my niece attending the prestigious Rose-Hulman Institute of Technology, to my previous career where I installed CNC machines in various parts of the state. While many may think the state is a giant wind power farm, there is a great deal of industry and manufacturing throughout the state including pharmaceutical and medical devices, mining, and transportation. The leading energy provider for the state, Duke Energy, also supports these manufacturers with programs to incentivize (through rebates) products which increase efficiency.

We’ve mentioned energy rebates previously and I have recently had the chance to help a customer with their energy rebate. More often than not, these rebates are an after thought, I hope that after reading this we can help you to check with your local service provider to see if they offer a similar process – they are available throughout the country from MANY electricity providers. The process for this customer was based off purchasing a single Soft Grip Safety Air Gun with Stainless Steel Mini Super Air Nozzle. The rebate was focused on the engineered air nozzle. For a 1/8″ NPT nozzle, it must consume 10 SCFM or less at 80 psig inlet pressure. For a 1/4″ NPT nozzle, they have to consume 17 SCFM or less at 80 psig. The fact the nozzle was assembled onto a Soft Grip Safety Air Gun enabled the customer to apply for a rebate for the full cost of the whole air gun.

EXAIR Model 1299SS – Soft Grip Safety Air Gun w/ Stainless Steel Mini Super Air Nozzle

The value of the rebate for Indiana where Duke is the energy supplier is $40.00 USD per engineered nozzle installed. The rebate is capped at 75 percent of the project cost in Indiana. The current cost of the 1299SS is $134.00, which enables this customer to the full $40.00 for each Safety Air Gun with Mini Super Air Nozzle they install. This is one of the simplest prescriptive rebates in the Duke Energy program. The main focus here is to conserve compressed air which ultimately puts more energy available to the rest of the grid. The engineered nozzle prescriptive rebate is just one way that Duke Energy customers in the state of Indiana can save.

If you are in the state of Indiana (OR ANYWHERE ELSE IN THE USA) and would like to discuss whether the Safety Air Guns or any point of use compressed air application in your facility can be improved, contact an Application Engineer. The truth is we all love saving a customer their resources, whether it be compressed air, electricity, liquid, or good old-fashioned cash.

EXAIR Products Qualify for Energy Rebates

The use of compressed air can be found in almost any industry and is often referred to as a “fourth utility” next to water, gas and electric. The generation of compressed air accounts for approximately 1/3 of all energy costs in an industrial facility, in many cases, it’s the largest energy user in an industrial plant. With an average cost of $ 0.25 per every 1,000 SCF used, compressed air can be expensive to produce so it is very important to use this utility as efficiently as possible.

Many utility companies recognize the benefit of using engineered products to reduce compressed air usage, like the ones manufactured by EXAIR, and offers rebate incentives for making a switch. Duke Energy, who supplies power to sections of North Carolina, South Carolina, Ohio, Kentucky, Indiana and Florida offers several “Smart $aver Rebates” that focus around the generation and use of compressed air. (State and Location Dependent)

Duke Energy’s Smart Saver Program

However the best place to look at your states available programs is the DSIRE database. DSIRE is the most comprehensive source of information on incentives and policies that support renewable energy and energy efficiency in the United States. Established in 1995, DSIRE is operated by the N.C. Clean Energy Technology Center at N.C. State University. Follow the link above to read about the history of DSIRE, the partners on the project, and the research staff that maintains the policy and incentive data in DSIRE.

The Process is pretty easy! Visit https://www.dsireusa.org/ and type in your Zip Code!

After you get your results, search some key words, Like “Industrial” “Energy” “Commercial” “Energy Efficiency” “Compressed air”

Here you can see the two Programs that came up for 46077, you can then click the program name and it will take you a information page with the programs website and information!

Here at EXAIR, much of our focus is to improve the overall efficiency of industrial compressed air operating processes and point of use compressed air operated products. If you’d like to contact one of our application engineers, we can help recommend the proper engineered solution to not only save on your compressed air usage but also assist with possible energy rebates available in your area.

Adjustable Air Amplifiers: Versatile, Rugged, and EFFICIENT!

Adjustability is a key feature for several EXAIR Intelligent Compressed Air Products… for example our Adjustable Air Amplifiers.  The ‘adjustable’ part has to do with setting the air flow volume and force:

Just loosen the locking ring, and you can thread the plug out of, or in to, the body to increase, or decrease the flow and force of the developed flow.  There’s a hole in the plug (opposite the “EXAIR.com” stamp) so you can use a spanner wrench (another adjustable tool!) to thread the plug in or out.

You can get an amazing range of flow from a little twist*:

These are the performance values for a Model 6042 2″ Aluminum Adjustable Air Amplifier with a compressed air supply pressure of 80psig. Regulating the pressure can give you even lower…or higher…flows.                                              *0.002″ to 0.010″ is about 1/4 turn of the plug.

A gap of about 0.010″ is about the max for 80psig supply pressure.  Above that, the air flow overwhelms the Coanda profile, creating a turbulent ‘storm’ in the throat, hampering the efficiency and effectiveness. The proper “adjustment” for that is to select the next larger Air Amplifier!

While the range of air flow is certainly impressive, their versatility is another major factor in their selection.  I reviewed our Application Database (registration required) for real-life details on Adjustable Air Amplifiers “in the field” and found a litany of other benefits that made them better suited to particular installations than a Super Air Amplifier:

  • A customer who builds automated equipment incorporates the Model 6031 1-1/4″ SS Adjustable Air Amplifier to blow open bags with a puff of air as they move into position on an automated filling machine. They use it because it’s available in stainless steel construction, and it’s still compact & lightweight.
  • A mattress manufacturer uses Model 6043 3″ Aluminum Adjustable Air Amplifiers to cool mattress springs.  They’re lightweight, the perfect size to match the springs’ profile, and they can “dial them out” for high heat removal before putting springs on a rubber conveyor.
  • A tier 1 automotive supplier has Model 6234 4″ SS Adjustable Air Amplifier Kits installed on their robotic paint line to blow off moisture from parts to prevent water spotting between the wash cycle and the oven.  They use them because the stainless steel construction holds up to high heat due to the proximity to the ovens.
  • A food plant uses Model 6031 1-1/4″ SS Adjustable Air Amplifiers to improve the drying time of 3,000 liter mixers that must be washed between batches of different products.  The stainless steel construction holds up to the rigors of the frequent washdown in this area.
  • A bedding manufacturer replaced a regenerative blower with a Model 6041 1-1/4″ Aluminum Adjustable Air Amplifier for trim removal on stitched fabric at bedding manufacturer.  The blower was prone to failure from lint & dust; the Air Amplifier, with no moving parts, is not.  It’s also compact, lightweight, and virtually maintenance free.
  • A light bulb manufacturer installed Model 6030 3/4″ SS Adjustable Air Amplifiers on the ends of open pipes that were used to cool mercury lamp wicks.  This reduced noise levels significantly while providing the same cooling rate, and the stainless steel construction holds up to the heat of the operation.

Because of the simplicity of their design, Adjustable Air Amplifiers are also extremely adaptable to custom applications.  We’ve added threads or flanges to the inlets and outlets of several different sizes, to accommodate ease of mounting & installation:

Among other custom Air Amplifiers, we’ve put (left to right) threads on the outlet, ANSI flanges on the inlet/outlet, Sanitary flanges on the inlet/outlet, and Sanitary on the inlet/ANSI on the outlet. How are you installing your Air Amplifier?

Adjustable Air Amplifiers are available in both aluminum and 303SS construction, to meet most any environmental requirements…except extreme high heat.  In those cases, the Model 121021 High Temperature Air Amplifier is rated to 700°F (374°C) – significantly higher than the Aluminum – 275°F (135°C) or the Stainless Steel – 400°F (204°C).  They’re commonly used to circulate hot air inside furnaces, ovens, refractories, etc.

A Model 121021 1-1/4″ High Temp Air Amplifier directs hot air to a rotational mold cavity for uniform wall thickness of the plastic part.

Adjustability.  Versatility.  Durability.  If you’d like to know more about the Adjustable Air Amplifier, or any of EXAIR’s Intelligent Compressed Air Products, give me a call.
