EXAIR Efficiency Lab at Your Service

I couldn’t count the number of times we have written a blog about the EXAIR Efficiency Lab because its that cool, unlike the number of wins the Cincinnati Reds have right now. I can count that on two hand 10………10-26 as of writing this blog and I could go on and on about the pain but I will spare you the tears and write about how amazing the Efficiency lab is for any company that utilizes compressed air!

Is the Mascot signing something? Or hanging his head? We will never Know!

First – what is the EXAIR Efficiency Lab? Well several years ago EXAIR created a free program called the Efficiency Lab.  This program is to compare your current pneumatic blow-off device with an EXAIR engineered product.  The values we compare are air consumption, noise level and force. We generate a detailed report to send to you for review.  It is a free service that EXAIR provides for U.S. and Canadian companies to know more details about solutions you are currently using in your processes.

The EXAIR Efficiency Lab

Why do we offer this?  Air Compressors demand significant electrical power and compressed air is considered to be a fourth utility within plants and industries.  Many people do not realize the cost and safety concerns when using improper blow-off devices.  As an example, if you look at a single 1/8” open pipe for blowing compressed air, it can cost you over $2,000 a year to operate.  This will add to your overhead and cut profits.  Another reason to consider your blow-off device is that compressed air can be dangerous.  With that same 1/8” open pipe, it can violate OSHA standards for noise exposure and dead-end pressure.  In deciding your “vehicle” for blowing compressed air, cheap is not typically best option.  To put it in other terms, a cheap nozzle is like a cheap old car, it’s cheap because it gets 3 MPG with faulty brakes.

With our Efficiency Lab, a comparison it is quite simple to do.  An easy way is to call us and explain the details. These details can be data such as the inside diameter and length of a an open tube you are using, or the actual performance data of a cheap air nozzle you have chosen to use. Perhaps the easiest way to make the comparison is to let EXAIR do it – send in your blowoff product or a sample of the tube, nozzle, modified fitting, etc. We will then put them through our testing process. You can also fill out our Product Efficiency Survey on our website to give the conditions for testing. 

We will run the tests at the specified conditions or in a range of settings.  We will then return your pneumatic device back to you at our cost with a detailed report of the comparison.  Your information will be confidential, and we will not share it without your permission.  We will also provide a simple ROI – many customers like to use this report to show managers, executives, HSE, etc. on the improvements that EXAIR can provide including cost savings and safety.

How do we do the Efficiency Lab?  We use calibrated equipment and standardized procedures to test for noise levels, flow usage, and force measurements.  We will recommend an EXAIR engineered solution as a replacement to your current device to do the comparison.  With the analytical information, we can also figure the total amount of air savings, return on investment, payback period and safety improvements.

Don’t Swing and miss…. (Like the Reds)  You do not want to sacrifice safety, time, and money with a sub-standard product.  Let EXAIR solve this dilemma with our free service; the Efficiency Lab.  Take advantage of our expertise by using the Efficiency Lab service, we will provide you a detailed report with a comparison analysis to make a great choice.

EXAIR’s Efficiency Lab Shows How Much Compressed Air You Can Save

The EXAIR Efficiency Lab

EXAIR has been manufacturing compressed air products since 1983, and we created a culture of making high quality products that are safe, effective, and very efficient.  Since we stand by our products, we created a program called the Efficiency Lab.  This program is to compare your current pneumatic blow-off device with an EXAIR engineered product.  The values we compare are air consumption, noise level and force. We generate a detailed report to send to you for review.  It is a free service that EXAIR provides for U.S. and Canadian companies to know more details about solutions you are currently using in your processes.

Compressed Air and Pneumatic Systems

Compressed Air Pipe

Compressed air is used to operate pneumatic systems in a facility, and it can be segregated into three main sections; the supply side, the demand side, and the distribution system.  The supply side is the air compressor, after-cooler, dryer, and receiver tank that produce and treat the compressed air.  They are generally found in a compressor room.  The demand side is a collection of devices that will use the compressed air to do “work”.  These pneumatic components are generally scattered throughout the facility.  To connect the supply side to the demand side, a distribution system is required.  Distribution systems are pipes or tubes which carry compressed air from the air compressor to the pneumatic devices.  The three sections have to work together to make an effective and efficient system.

Compressed air is a clean utility that is used in many different ways, and it is much safer than electrical or hydraulic systems.  But most people think that compressed air is free, and it is most certainly not.  Because of the cost, compressed air is considered to be a fourth utility in manufacturing plants.  For an electrical motor to reduce a volume of air by compressing it, it takes roughly 1 horsepower (746 watts) to compress 4 cubic feet (113L) of air every minute to 125 PSI (8.5 bar).  With almost every manufacturing plant in the world utilizing air compressors larger than 1 horsepower, the amount of energy needed is extraordinary.

Let’s determine the energy cost to operate an air compressor by Equation 1:

Equation 1:

Cost = hp * 0.746 * hours * rate / (motor efficiency)

where:

Cost – US$

hp – horsepower of motor

0.746 – conversion KW/hp

hours – running time

rate – cost for electricity, US$/KWh

motor efficiency – average for an electric motor is 95%.

As an example, a manufacturing plant operates a 100 HP air compressor in their facility.  The cycle time for the air compressor is roughly 60%.  To calculate the hours of running time per year, I used 250 days/year at 16 hours/day.  So operating hours equal 250 * 16 * 0.60 = 2,400 hours per year.  The electrical rate for this facility is $0.10/KWh. With these factors, the annual cost to run the air compressor can be calculated by Equation 1:

Cost = 100hp * 0.746 KW/hp * 2,400hr * $0.10/KWh / 0.95 = $18,846 per year in electrical costs.

Filters and Regulator

If we look at the point-of-use or demand side, the compressed air is generally conditioned to be used to run and control the pneumatic system.  The basic units include filters, regulators, and lubricators.  The filters are used to remove any oil, water, vapor, and pipe scale to keep your pneumatic system clean.  They fall into different types and categories depending on the cleanliness level required.

Filter Separators are more of a coarse filtration which will capture liquid water, oil, and particulate.  The Oil Removal Filters are more of a fine filtration which can capture particles down to 0.03 micron.  They are also designed to “coalesce” the small liquid particles into larger droplets for gravity removal.  One other group is for removing oil vapor and smell.  This type of filter uses activated charcoal to adsorb the vapor for food and pharmaceutical industries.  Filters should be placed upstream of regulators.

Pressure Regulators change the pressure downstream for safety and control.  Pneumatic devices need both flow and pressure to work correctly.  The lubricator, which is placed after the Regulator, helps to add clean oil in a compressed air line.  Air tools, cylinders, and valves use the oil to keep seals from wearing with dynamic functions.  Once the compressed air is “ready” for use, then it is ready to do many applications.

For EXAIR, we manufacture products that use the compressed air safely, efficiently, and effectively.  EXAIR likes to use the 5-C’s; Coat, Clean, Cool, Convey and Conserve.  We have products that can do each part with 16 different product lines.  EXAIR has been manufacturing Intelligent Compressed Air Products since 1983.  Compressed air is an expensive system to operate pneumatic systems; but, with EXAIR products, you can save yourself much money.  If you need alternative ways to decrease electrical cost, improve safety, and increase productivity when using compressed air, an Application Engineer at EXAIR will be happy to help you.

EXAIR’s Efficiency Lab: A Service Providing ROI

EXAIR’s Free Efficiency Lab

Have you ever stood at a dealership wondering what car to buy?  You have a variety of things to consider like safety, gas mileage, quality and price.  But what if the dealership had a professional race car driver to test each car for you and give you a detailed report about each one?  That would definitely help you to make a better choice.  At EXAIR, we are that professional driver when it comes to compressed air products.

EXAIR has been manufacturing compressed air products since 1983, and we created a culture of making high quality products that are safe, effective, and very efficient.  Since we stand by our products, we created a program called the Efficiency Lab.  This program is to compare your current pneumatic blow-off device with an EXAIR engineered product.  We generate a detailed report to send to you for review.  It is a free service that EXAIR provides for U.S. and Canadian companies to “test drive” your current pneumatic blow-off items.

Why do we offer this?  Air Compressors use a lot of electrical power and are considered to be a fourth utility within plants and industries.  Many people do not realize the cost and safety concerns when using improper blow-off devices.  As an example, if you look at a single 1/8” open pipe for blowing compressed air, it can cost you over $2,000 a year to operate.  This will add to your overhead and cut profits.  Another reason to consider your blow-off device is that compressed air can be dangerous.  With that same 1/8” open pipe, it can violate OSHA standards in noise exposure and dead-end pressure.  In deciding your “vehicle” for blowing compressed air, cheap is not the best option.  In reference to my analogy above, it would be like buying a car that gets 3 MPG with faulty brakes.

With our Efficiency Lab, it is quite simple to do.  For starters, you can go to our Product Efficiency Survey on our website to give the conditions for testing.  If you wish for a side by side analysis, you can place your pneumatic device in a box and send it to EXAIR.  We will run the tests at the specified conditions or in a range of settings.  We will then return your pneumatic device back to you at our cost with a detailed report of the comparison.  Your information will be confidential, and we will not share it without your permission.  Many customers like to use this report to show managers, executives, HSE, etc. on the improvements that EXAIR can provide in cost savings and safety.
