Understanding your ROI for EXAIR Products

I used to hold a purchasing/engineering role for a previous company and as part of that role I was required to understand all costs of a project. The value of knowing the return of your investment is obvious but the benefit of this knowledge enhanced communications with other team members and at times with your customer. So how can I understand the economic impact from purchasing and Intelligent Compressed Air product from EXAIR?

EXAIR makes an easier job of calculating your ROI when purchasing our product(s). Simply go to www.EXAIR.com and click on “Resources”, located on the top center of our homepage. You will see “Calculator Library” where you can see our “Air Savings Calculator“.

Calculating your ROI using this tool is simple, simply place your current consumption rate (SCFM), the cost of our product(s), the SCFM for our product(s) and your cost of compressed air per 1000 Cubic feet (if this is unknown, $0.25/1000 cubic feet is a reasonable number to use).

  1. Current Consumption (SCFM): This is the current air requirements for your current process.
  2. Cost of EXAIR Product(s): This is the expenditure of the EXAIR product(s) being purchased.
  3. EXAIR Product(s) consumption (SCFM): This can be found in our catalog, web site or by calling EXAIR and talking to an Application Engineer.
  4. Cost of Compressed Air: This can be determined at your facility or a good industry average is $0.25/1000.

The calculator will automatically calculate your return and show you the payback in number of days. EXAIR encourages the use of our website and/or calling our Application Engineers for additional information or education on air savings. We are customer friendly and always eager to help.

Take It All In – Just Filter It

The Nose – Only the Nose Knows

Take a nice deep breath as you read this. In through the nose. If you are like me right now, due to Fall allergies you’ll have a little bit of a restriction, hold it for just a second and then breathe out through the mouth. The body is an amazing thing, when we breathe in through our nose the body has some natural filtration built in that is also known as nose hair. While not the most attractive thing to most, it is important. The hairs in the nose help to filter out allergens and catch foreign debris.

Other items you interact with daily have similar air intake filtration. A car often has both an intake air filter and even an in-cabin air filter, these both protect various parts. The engine air filter is vital to prevent dust, debris and even excessive water from entering into the precision machined and assembled motor. The HVAC system in every business or home generally has an intake air filter in order to protect the coils and heater box.

There’s another system in most manufacturing facilities that should always have a filter on it, and that is the compressed air system. Properly maintaining and filtering the incoming ambient air feed before it is compressed starts the process of on the right foot to optimize performance and insure efficiency is maintained from the start of the entire process. These filters are like many others and can be part of a preventative maintenance program. The air compressor manufacturer will have a recommendation on frequency for the various types.

If these filters are left unchanged then the compressor begins to have restricted flow on the intake which then results in less air being pulled in or maybe the filter is removed and then the debris all gets pulled in and sent through to become foreign debris inside the compressor. Both of these will cause the compressor to wear or overheat and work harder to compress the air and send it into the storage tank. This results in premature maintenance needed on the compressors and or point of use devices.

Thus, always filter your incoming air. Whether for your air compressor, car engine, or house, start with a fresh intake and then keep it optimized from there. The payback will be longer lasting equipment that operates at a higher efficiency. And remember, breathe in through your nose.

If you would like to discuss your filtration setups, feel free to reach out to an Application Engineer.

Intelligent Compressed Air®: The Double-Acting Reciprocating Air Compressor

Evaluating all of the different types of compressors and which is right for you can seem like a daunting task. Today, I’d like to take some time to talk about the Double-Acting Reciprocating type of air compressor.

Double-Acting Reciprocating compressors are a subset of the larger family of positive displacement compressor types. In positive displacement compressors, air is drawn into a chamber where the volume is then mechanically reduced. The energy used to displace the air volume is converted to an increase in air pressure. Dynamic compressors operate a little differently. They utilize an increase in air velocity to create the change in pressure. Air is accelerated to a high velocity through an impeller. The kinetic energy of the air is converted to an increase in potential (pressure) energy.

The Double-Acting Reciprocating compressor is a close relative to the Single-Acting Reciprocating compressor. In these types of compressors, an “automotive-type” piston driven by a crankshaft provides the compression. In a Double-Acting Reciprocating compressor, air is compressed as the piston moves in each direction. Hence the name, “double-acting”. In a Single-Acting Reciprocating compressor, air is only compressed on each full revolution of the piston. This makes the Double-Acting Reciprocating compressor much more efficient than its brethren.

Double-Acting Reciprocating compressors are also available in much larger sizes. While Single-Acting compressors can be found up to 150HP, generally they’re much less common any larger than 25HP. Whereas a Double-Acting compressor is available from 10HP-1,000HP, making it a better choice for larger plants that require a significantly greater volume of compressed air. While they’re a bit more expensive due to the added mechanisms to produce the double-action compression, this cost is quickly offset by the increase in efficiency. At a performance of 15-16 kW/100 cfm, they’re 32% more efficient than a single-acting reciprocating compressor.

If you’re in the market for a new compressor and are struggling to determine the most suitable compressor, talk with your local compressor sales representative. Once you’re up an running, EXAIR has a wide-range of products that’ll make sure you’re using your compressed air safely and efficiently!
