Save Compressed Air with the EXAIR Electronic Flow Control

The best way to save compressed air is to simply turn it off when it’s not being used. This might seem pretty simple, but there may be processes in your facility where this couldn’t be achieved by just turning a valve. In applications where product is traveling along a conveyor, and must be dried, cooled, or blown off, there is likely some spacing in between the parts. It isn’t necessary to keep the blowoff running constantly if there’s periods of intermittent spacing. To help reduce the overall load on the air compressor, implementing a solution to shut the air off in between each part can have a dramatic impact. EXAIR’s Electronic Flow Control, or EFC, is designed to improve efficiency by reducing overall compressed air usage. It utilizes a photoelectric sensor that detects when the part is present. When it’s not, it triggers a solenoid valve to close and shut off the compressed air supply.

EXAIR EFC

One way to use the Electronic Flow Control would be for Turning a Atomizing Spray nozzle on to coat your product.  For example see the photo below where you could use the EFC to sense the pants coming down the line. Then turn the air supply on to spray a bleach solution to get the weathered look you are after. Once the pants pass the EFC will turn the nozzle off, replacing a manual operation awhile saving compressed air and your liquid solution!

Another use would be to tell when a hopper that is being filled by a Line Vac is empty or over filled.  You can adjust the sensor and the control module to sense that the hopper is empty and it will turn the compressed air on to the Line Vac to then feed the hopper.  Then set the timer module so it will run for the length of time it takes to fill the hopper.  The other way would be to place the sensor at the top of the hopper and have it sense when the pile of media has reached the full level.

The EFC models available from stock can accommodate flows up to 350 SCFM. For applications requiring more compressed air, EFCs with dual solenoids are also available. If you have an application in one or more of your processes where intermittent compressed air use could help save you money, give us a call. We’d be happy to take a look at the application and help determine just how quickly the EFC could start paying YOU

Know How Much Money You Can Save with EXAIR’s Efficiency Lab

 
Free testing. Verifiable data. EXAIR Efficiency Lab.

When it comes to buying new gear for any kind of outdoor hobby the research almost becomes a full-time job to decided what to get. When I’m hanging 200 ft. in the air off of a single rope, I want to make sure that my harness, rope, and all my other gear is top notch and not going to fail me as my literal life is hanging on the line. Sometimes it would be nice to have a professional climber standing there telling you all of the pros and cons, what they like and dislike about it, and weather it’s worth the buy. Outdoor gear is expensive and climbing equipment is no exception, in an ever-changing world of innovation new things are coming out every week and is just to hard for one person to keep up with.

Similarly, EXAIR has multiple product lines, many new products, and countless applications for our products. That is where our Application Engineers come in; as experts on our products and their applications we can provide in-depth knowledge on the various uses and expected outcomes. 

EXAIR’s Products in action

EXAIR has been making compressed air products since 1983, and have since created a culture of making high quality, safe, and efficient compressed air products. With this in mind we started the Efficiency Lab program for people to take advantage to test your current pneumatic blow-off device and compare it to an EXAIR Intelligent Compressed Air product. We will generate a detailed report on our findings and send it to you for your review. This free service provided to U.S. and Canadian companies allows people to test and look into possible upgrades and cost savings.

During my time as a project and process engineer at Valeo and Tyson I wish I had known about this service.  The Efficiency Lab allows you to look at what your current process is, whether it is an open-ended pipe or some other nozzle and have EXAIR compare it to an EXAIR product for free. Its like getting a free inspection of all your gear and having an expert help you find the best replacement if needed.

You may be wondering why we offer this service; it’s simple, compressed air can be expensive and we want to save you money. Not only are open ended pipes unsafe and can violate OSHA Standards on both dead-end pressure and noise level, but they also use a lot of compressed air. To operate an 1/8” open pipe you are looking at over $2000 a year for just one pipe; there isn’t a single plant that is just going to use one pipe. That is a lot of money that can add up over time, which could easily be saved by changing out what you are using.

The Efficiency Lab is quite simple to use. The simplest way is to contact us (my info below) and we can exchange the information needed to get your product into EXAIR. Once received, we will proceed. We will then calibrate the equipment and standardized procedures to test for noise level, air consumption, and force generated. Based off of this information we will recommend a similar product. Don’t be afraid, let us take care of the hard part of choosing which product is best for your application. If you cannot send any product in, use our  Product Efficiency Survey to provide as many details as possible. 

If you have any questions about compressed air systems or want more information on any of EXAIR’s products, give us a call, we have a team of Application Engineers ready to answer your questions and recommend a solution for your applications.

Engineered Air Nozzles Keep Your Operations Safe

If you are looking for a way to save money and make your blow off applications safer, look no further than EXAIR’s Engineered Air Nozzles & Jets. By upgrading your blowoff, cooling, and drying operations to use one of our Super Air Nozzles or Jets you can save as much as 80% of your compressed air usage when compared with an inefficient solution. Plus you can remove open ended pipes and other unsafe blow offs that OSHA will fine you for.

An open copper pipe or tube, even if “flattened” as we commonly see, wastes an excessive amount of compressed air. This wasted compressed air can create problems in the facility due to unnecessarily high energy costs, maintaining system pressure that can affect other processes and excessive noise exposure for personnel. An open pipe or tube will often produce sound levels in excess of 100 dBA. At these sound levels, according to OSHA, permanent hearing damage will occur in just 2 hours of exposure.

By simply replacing the open tubes and pipe with an EXAIR Super Air Nozzle, you can quickly reduce air consumption AND reduce the sound level. Sound level isn’t the only thing an OSHA inspector is going to be concerned about regarding an open pipe blowoff, in addition OSHA 1910.242(b) states that a compressed air nozzle used for blowoff or cleaning purposes cannot be dead-ended when using with pressures in excess of 30 psig. I don’t know if you’ve ever tried to use an air gun with 30 psig fed to it, but the effectiveness of it is dramatically reduced. This is why there needs to be a device installed that’ll prevent it from being dead-ended so that you can operate at a higher pressure.

EXAIR’s Super Air Nozzles are designed for maximum performance and safety. The engineered features keep EXAIR nozzles running quietly, and cannot be dead-ended. Using an OSHA compliant compressed air nozzle for all points where a blowoff operation is being performed should be a priority. Each individual OSHA infraction will result in a fine if you’re surprised with an OSHA inspection. Inspections are typically unannounced, so it’s important to take a look around your shop and make sure you’re using approved products.

You’ll find all of the tools you need in the EXAIR catalog. Click here if you’d like a hard copy sent directly to you! Or, get in touch with us today to find out how you can get saving with an Intelligent Compressed Air Product.

EXAIR’s Return on Investment For One Engineered Air Nozzle is Amazing!

Return on Investment (ROI) is a measure of the gain (preferably) or loss generated relative to the amount of money that was invested.  ROI is typically expressed as a percentage and is generally used for financial decisions, examining the profitability of a company, or comparing different investments.  It can also be used to evaluate a project or process improvement to decide whether spending money on a project makes sense.  The formula is shown below-

ROI
ROI Calculation
  • A negative ROI says the project would result in an overall loss of money
  • An ROI at zero is neither a loss or gain scenario
  • A positive ROI is a beneficial result, and the larger the value the greater the gain
1100group
Our catalog publishes most products’ performance and specification data for a compressed air supply pressure of 80psig.

Example – installing a Super Air Nozzles (14 SCFM compressed air consumption) in place of 1/4″ open pipe (33 SCFM of air consumption consumption) .  Using the Cost Savings Calculator on the EXAIR website, model 1100 nozzle will save $1,710 in energy costs. The model 1100 nozzle costs $42, assuming a $5 compression fitting and $45 in labor to install, the result is a Cost of Investment of $92.00. The ROI calculation for Year one is-

ROI2

ROI = 1,759% – a very large and positive value.  Payback time is only 13 working days!

If you have questions regarding ROI and need help in determining the gain and cost from invest values for a project that includes an EXAIR Intelligent Compressed Air® Product, feel free to contact EXAIR and myself or one of our Application Engineers can help you determine the best solution.
