More Power? I DO Think So…

We occasionally get calls from folks who are looking for “more power” – and it always brings that classic 1990’s sitcom “Home Improvement’s” Tim “the Tool Man” Taylor to mind. Well, not so much Tim’s “more power” mantra, but the ubiquitous response from his long-suffering sidekick, Al Borland:

Al knows it.  George Foreman knows it. Lisa knows it.  Even Tim knows it, this time.

Sometimes, they’re looking for a product to replace what they’re currently using…something they’re not getting desirable results from. Other times, they have an EXAIR product in place, and it’s just not getting the job done.

Our first response is, of course, to make sure they’re getting a sufficient supply of air to their product, no matter whether it’s ours or not. If you’re familiar at all with our blogs, you know we write about this frequently:

3 Common Mistakes in Your Compressed Air System

Once we’ve made sure that the product is indeed receiving appropriate air supply, we can look at adding to the flow rate and force of the air stream. We’ve made it easy to do that with a variety of blow off products by designing them with a replaceable shim.

All of our Air Knife products (Super, Standard, and Full Flow) will ship with a 0.002” thick shim installed. These will perform superbly in a wide variety of general industrial blow off applications. If this doesn’t provide the force needed for your application, we carry Shim Sets for any Air Knife that will allow you to double, triple, or even quadruple the air flow for amplified thrust. Some common examples are stubborn debris in tight spaces (like the fins of a fin-and-tube heat exchanger) or removing oil from a corrugated surface.

From left to right: Super, Standard, and Full Flow Air Knives.

 

Like the Air Knives, our Air Wipes (Super and Standard) are built with 0.002” thick shims, which can be easily replaced for additional flow and force. Like when the Air Wipe is getting all the coolant off an extruded & machined part, but some stubborn, hair-like fibers need a little more “oomph” to remove.

 

Super (left) and Standard (right) Air Wipes come in sizes from 1/2" to 11".

Super (left) and Standard (right) Air Wipes come in sizes from 1/2″ to 11″.

Yes, those were real calls I took. Yes, they had sufficient air flow. Yes, the extra shims worked like a champ.

Similar to our Air Knife products, our Flat Super Air Nozzles also incorporate a replaceable shim. In fact, you have your choice of standard Models with a 0.015” thick shim installed, or High Power Models with a 0.025” thick shim. Shim Sets with a variety of thicknesses from 0.005” to 0.030” are available for either of these.

Our Super Air Amplifiers and High Velocity Air Jets incorporate patented shims that make for the highest amplification flows available, anywhere. These are available, from stock, in Shim Sets or individually.

High Velocity Air Jets and Super Air Amplifiers use patented shims for optimum performance and efficiency.

If you have an air blowing application that you’d like to get a little (or a lot) more out of, give us a call. Prepare for a discussion on proper air supply first (of course,) but we’ll be more than happy to help in any way that we can.

Super Ion Air Knife Solves Vinyl Printing Static Issue

I recently worked with a customer who was starting to get rejects in their vinyl printing press process. As the sheet enters the machine, the vacuum turns on to hold it in place as the printer head passes over. Due to static buildup, the sheet was getting wrinkles resulting in an unusable finished product so they called EXAIR looking for a solution.

I recommended using our 60” Super Ion Air Knife and mounting the unit on the side of the press, blowing the ionized air across the vacuum table. The Super Ion Air Knife provides a laminar sheet of ionized air across the entire length of the knife. By using a pressure regulator to adjust the supply pressure, the force and flow can be controlled to meet the demands of a specific application.

Available in one-piece lengths from 3″ to 108″.

This time of year, static electricity becomes a major issue with many industrial applications. We have recently written blogs entitled Hello Static and Winter Cold = Static Issues (just to name a few),  outlining some common causes and negative results.

If you are beginning to experience static issues in your plant, please contact us at 1-800-903-9247 to see how we can help.

EXAIR.com offers Numerous Engineering Tools

Today, I want to take the opportunity to highlight some features on EXAIR’s website. EXAIR provides a website for technical information on products, point of sale and research on compressed air topics in general. For instance, if you would like to know, How a Vortex Tube Works, the Droplet Size of our Atomizing Spray Nozzles, or a Blow Off Comparison between a compressed air powered air knife and blower system, follow the links above and navigate to the topic that interests you on our website.

 

Our Air Savings Calculator will show you total dollars saved and payback time.

Our Air Savings Calculator will show you total dollars saved and payback time.

Our knowledge base features the CAD Library, Case Study Library, and Application Database. The Air Data Library is invaluable to any engineer specifying a compressed air piping system. It also features a great article for calculating air consumption at various inlet pressure. One of my favorite features though is the Air Savings Calculator.

The Air Savings Calculator allows you to calculate the cost of compressed air for various devices.  The cost of compressed air for high usage device like open blow offs, drilled pipes and uncontrolled compressed air devices can add up quickly. With the air savings calculator, you can quickly find out how much those (8) 1/16″ inner diameter 18″ long open pipes are costing you per year ($2,016 if you are operating at 80 PSIG).

Some of the material that we make available to our visitors we request that you register on the site. The registration is a simple process to complete. Why would you want to take the time to give us you information? First, registering on EXAIR’s site gives access to our library of product applications for the last thirty years EXAIR has tracked how our products have been used to help our customers solve their industrial needs. Second, EXAIR members are granted access to CAD models in 2D and 3D of our products. The 3D models can easily import into AutoCAD Inventor®, Solidworks®, or PRO Engineer®. These models will allow you to easily import EXAIR products into your design to verify the fit and mounting in complex systems. Third, EXAIR Case Study library offers detailed analysis of economics, safety, and utility savings of using EXAIR products.

What is the USB Data Logger for Digital Flow Meters? How Can It Help Me?

USB Data Logger

The USB data logger works with all of EXAIR’s Digital Flow Meters and provides valuable feedback for optimizing your compressed air system.

EXAIR’s Model 9147 USB Data Logger has become one of the most valuable tools that we sell to help customers get a “view” of their compressed air usage over time. One of the important tenets we promote at EXAIR is energy savings by prudent use of compressed air through our engineered solutions (Air Knife, Air Nozzles, Air Amplifier, etc.). But how does a person in charge of such systems really “know” whether they are helping or hurting their compressed air system?

The first step is to have an appropriate flow meter which can give an indication of how much air volume is being used. EXAIR’s line of Digital Flow Meters are perfect for getting to that point with instant and direct readings that don’t need to be calculated any further. What you see on the meter is the flow in either SCFM or m3/hr calibrations.

The second step is to attach the USB Data Logger to the Digital Flow Meter so that readings can be kept over time. It is like setting up a security camera for your compressed air system. Nothing gets by without being recorded.

The USB Data Logger can be connected to just about any type of monitoring system that has a 4 – 20 mA output to which the 2-wire harness can be installed. A quick and easy initialization to choose the unit of measure, to select the frequency of measurement and some optional alarms is all that is necessary. The software package is included with the USB Data Logger and is convenient to run on a typical desktop or laptop computer. You simply, set it and forget it (at least until you want to do some reporting).

The reporting is how the USB Data Logger can help you as the person concerned with monitoring the compressed air use in your facility. Once the defined monitoring period of time has passed, the USB Data Logger can be removed from its socket, stopped from recording and the data is then downloaded into a suitable format that can be imported into EXCEL or other spreadsheet program for creating charts to analyze what is happening, when it is happening and how much compressed air is being used. In the analysis, you can compare the flow data and times with certain problems in a production line that might cause low pressure condition which shuts machinery down. You might also be able to determine where additional, point of use compressed air storage might be needed close to certain processes.

Ultimately, the USB Data Logger allows you to “see” your compressed air system in a way that allows you to sleuth out problems seen that might have no other explanation. It can also help you to justify your air savings when you apply the other air saving compressed air products that EXAIR produces by monitoring a base line for “before” performance and “after” performance. After all, it if is important to your organization, it should be measured. And compressed air is certainly a utility that should be measured.

Ordering Off The Menu, Revisited

I wrote a while back about ordering off the menu, in regard to technical data on EXAIR products. I’d like to share another example of how we can help, if you don’t find just what you’re looking for in our catalog.

I recently had the pleasure of helping a new Line Vac customer – a machinery builder – who needed a combination of properties of two different products: the stainless steel construction of the 2” NPT Threaded Line Vac, but the performance of the 2” Heavy Duty Threaded Line Vac. The Installation & Operation Guide actually gives you instructions on drilling out the generator holes for increased air flow & performance, but they didn’t want to disassemble, modify, and reassemble the units if they didn’t have to. Which was fine with us – we were able to perform these modifications in assembly, and ship them, surprisingly quickly (surprising to our “new” customer anyway…) and they were quite pleased with the results. So much so, that the modified Line Vac is now standard equipment on this new machine.

Which of these Line Vacs has higher performance?  We can't be sure without checking the generator!

Which of these Line Vacs has higher performance? We can’t be sure without checking the generator!

We get a fair number of calls about products or applications that don’t EXACTLY fit the parameters, specifications, and performance ratings of our catalog products. Some of them simply won’t work…and we’ll tell you. Other times, though, we’re able to put our Design, Production, and Application Engineering skills to the task, and hit one out of the ballpark. And we’re set up to do it better than anyone else.

If you’d like to discuss a compressed air products application that’s a little (or a lot) “off the menu,” give us a call.

Full-Flow Air Knife Assists With Flour Recovery

I took a call from a customer who was looking for a way to recover residual corn flour on their chain and paddle, drag conveyor. As the paddles moved down the line, they would start accumulating flour which was leading to uneven batch runs and waste. After reviewing the application with the customer, they determined they were only needing to blow off the width of the paddles, so I recommend using our 18” stainless steel Full-Flow Air Knife.

The Full-Flow Air Knife provides a 30:1 amplification rate (entrained air to compressed air), to produce a high velocity curtain of air that travels the entire length of the knife. With a small profile of only 1” H x 1.25” W, the unit is the ideal choice where mounting space is limited. It is available in a 303SS material which was suitable for this wash-down application.

Full-Flow

The Full Flow Air Knife is available in aluminum or stainless steel construction, up to 36″ stocked lengths.

 

Due to the concern regarding dust, I recommended operating the unit at a gentle 20 PSIG, lowering the velocity to 3,000 FPM and reducing the air consumption to only 1.1 SCFM per inch. A simple pressure regulator is capable of adjusting the volume and velocity of output airflow in order to “fine tune” our knives per application. This would allow for the needed blowoff, as well as reduce the potential of the unwanted dust.

If you have a similar application or would like to discuss your process, please don’t hesitate to give us a call at 1-800-903-9247.
