Products Built to Last and Maintenance Free

As an avid outdoors man, I have learned a lot about myself during these days of quarantine and social distancing; mainly I don’t quarantine very well. With all the climbing gyms closed, traveling strongly discouraged, and social distancing in place my  lifestyle has been brought to a grinding halt much like many of us. opening up, which will be good for all of us. 

So, in place I have taken upon myself to learn a new hobby that I can do solo and safely. In the past weeks I have spent learning about mountain biking and all that comes with it. This includes the maintenance required to work on a bike, specifically the front derailleur which controls the front major gear changes (and gets damaged if crashed). Realigning the front derailleur is one of the hardest fixes that one can do on a bike as it has three different adjustments that need to be made at the same time. Thus, I embarked on a week long project of learning how to make the adjustment and man was it frustrating.

Performing tricky maintenance can be one of the most frustrating and stress inducing things when all you really want is for something to work without any hassle. Whether its hours just trying to figure out what the issue is or actually fixing it, let’s be honest, it never goes as planned. The same can be said for maintenance on things such as compressors, cars, and production equipment. Here at EXAIR we strive to eliminate this frustration and hair pulling maintenance and replace it with maintenance free products.

EXAIR’s lines of compressed air products such as our Vortex Tubes, Super Air Amplifiers, and Super Air Knives have no moving parts. No moving parts means no wear down parts and no wear down parts means little to no maintenance. Besides the occasional air filter element change out or something getting lodged inside the product EXAIR’s compressed air products will run almost indefinitely as long as they are supplied with a source of compressed air, typically run through a standard 5 micron filter separator. 

Although you cannot really prevent dirt from collecting in a filter separator (that is, in fact what they are meant to do) you can prevent dirt, dust, and debris from getting into your products by using one of EXAIR’s Filter Separators. Filter Separators remove water condensate, dirt, dust, and debris from your compressed air line before it enters your compressed air product. This prevents the particles from disrupting small air outlets or lodging in the small pathways inside our compressed air products and keeps the product running like new.

All in all, maintenance is not fun to have to deal with and can be costly at times. By using EXAIR’s engineered compressed air products you can eliminate at least one thing to worry about on your list of maintenance that needs to be performed. With a little bit of preventive measures you can keep our products running like new for years and years.

If you have any questions or want more information on any EXAIR’s of our products, give us a call, we have a team of application engineers ready to answer your questions and recommend a solution for your applications.

Compressor Maintenance: Steps to Minimize Wear

While I was still in college, I worked in a meat processing plant as a Project Engineer in the maintenance department. During my time in the maintenance department I learned the importance of proper maintenance on machines. A meat processing plant is one of the most taxing environments on machines as they will have to survive in extreme cold temperatures to extreme hot temperatures; they are also put through deep sanitation wash downs multiple times a day sometimes for periods of over an hour. The plant really put into perspective the importance of preventative maintenance of machines. This includes utilities such as a boiler and of course your air compressor.

Industrial Air Compressors
Neglected air compressors can cause a lot of issues ranging from expensive repairs to a decrease in efficiency. Wear and tear placed on the motor of an air compressor can cause the compressor to produce less compressed air (SCFM) at the same power consumption. This means you are paying the same amount of money for less compressed air.

A primary focus to prevent an increased amount of wear on your compressor motor is to seal up compressed air leaks. Leaks can cause the compressor to cycle more often and/or refill receiver tanks on a more frequent basis, causing the motor to run more often. With the motor having to run more often to keep the air present, it will wear down faster. Using EXAIR’s Ultra Sonic Leak detector, leaks can be found in the pipes so that they can be sealed up.

Another important maintenance is to make sure that the compressor gets cleaned. As the motor runs excess heat is generated; the heat generated then needs to be dissipated which is done by exhausting air through vents. If these vents become dirty or blocked and the air cannot escape then the temperature of the motor and winding resistance will increase; this in turn will shorten the life of the motor and increase the energy consumption. Using one of EXAIR’s Super Air Nozzles is a sure way to keep your compressor vents clean and dust free in a quiet and efficient manner.

There are many other items that require maintenance over time such as keeping belts in good condition and the drain traps clean. Good maintenance on any item whether it’s a production machine or  air compressor keeps it running a peak performance helping you save money and headaches in the long run.

Gen4 Static Eliminators: Cleaning as a Preventative Maintenance

The Gen4 Static Eliminators have been successful for EXAIR because of our robust design and great performance. They are rugged enough to be used in many industrial areas. EXAIR manufactures two styles; with and without compressed air assistance. For both types, preventative maintenance is still required to keep the Gen4 product line functioning optimally. In this blog, I will describe how to clean the points for years of hassle-free operations.

There are two common ways that an anti-static product will start to drift; contamination buildup and emitter point degradation. The degree of buildup is dependent on the environment. To create an ion, we have to apply a high voltage to a fine point. The high voltage is supplied by our Gen4 Power Supplies which generate 5,000 volts from a selectable 115Vac or 230Vac input. As the high voltage is pushed into a fine point; the energy creates a corona field.

Any contamination near or around that point can collect on its tip. The more contamination in the surrounding area, the faster the buildup will occur. Once the point gets coated, the ion production begins to decrease. Before this happens, the points should be cleaned with a soft-bristled brush as a preventative maintenance. Make sure that the power is turned off to the power supply and please do not use any liquid or cleaners on the points.

The second way is caused when the ionizing tips start to lose its sharpness caused by the cycle rate of ion production. Like a wick in a candle, a bit of material is lost over time. To mitigate this, our resistor-based line has replaceable ion points. This feature makes a cost-effective way to keep the points sharp, and the Static Eliminators like new. The video below shows how to clean and replace the ion points.

For any analysis with the Static Eliminators, EXAIR offers a model 7905 Static Meter. The Static Meter can help to find problem areas for best placement for the Gen4 Static Eliminators. It can also help to diagnose any static issues when cleaning is required and to help decide a preventative maintenance schedule. Whether is it a single point or multiple point product, the video above will help you to keep your machines running smoothly.

“An ounce of prevention is worth a pound of cure.”   With a maintenance schedule and a soft-bristled brush, you can protect your equipment from many issues with static. This would include machines jamming, difficult alignments, collection of debris, and hazardous shocks. EXAIR has a large line of Gen4 Static Eliminators to remove these static nuisances, and with the cleaning instructions above, you will have years of effective static removal. If static is affecting your operation, you can contact an Application Engineer at EXAIR to help select the correct solution.

Compressed Air Efficiency – How It Benefits Business

It is estimated that typically plants can waste up to 30 percent of their generated compressed air and that cost is substantial.  Considering the average cost to generate compressed air here in the Midwest is .25 cents per 1,000 Standard Cubic Feet, that translates into .075 cents for every .25 cents spent!  Compounded with the fact that energy costs have doubled in the last five years, it couldn’t be a better time to make your air compressor system more efficient.

The following steps will help you save air and in turn save money.

  1. Measure the air consumption to find sources that use a lot of compressed air.

Knowing where you stand with your compressed air demand is important to be able to quantify the savings once you begin to implement a compressed air optimization program. Placing a value upon your compressed air consumption will also allow you to place a value on its costs and the savings you will reap once you start to reduce your consumption. (EXAIR’s Digital Flow Meter)

  1. Find and fix the leaks in your compressed air system.

Not fixing your compressed air system leaks can cause your system pressure to fluctuate and affect your equipment negatively. It may cause you to run a larger compressor than necessary for your compressed air needs and raise your total costs. Or it could cause your cycle and run times to increase which leads to increased maintenance to the entire system. (EXAIR’s Ultrasonic Leak Detector)

  1. Upgrade your blow off, cooling and drying operations using engineered compressed air products.

Your ordinary nozzle with a through hole and a cross drilled hole can be an easy choice based upon price, but if you do not consider the operating cost you do not really know how much it is costing you. An Engineered Air Nozzle will pay for itself and lower operating costs quickly. Engineered Air Nozzles are the future of compressed air efficiency and are made to replace ordinary nozzles, homemade nozzles and open line blow offs. Engineered Nozzles reduce air consumption and noise levels; ordinary nozzles cannot compete. Engineered Nozzles maintain safety features and can qualify for an energy savings rebate from a local utility; ordinary nozzles fall short. Open blow off or homemade blow off applications typically violate OSHA safety standards; Engineered Nozzles do not.  (EXAIR’s Air Nozzles)

  1. Turn off the compressed air when it is not in use.

Automated solutions add solenoid valves and run them from your machine controls. If the machine is off, or the conveyor has stopped – close the solenoid valve and save the air.  And blow off applications can benefit from any space in between parts by turning the air off during the gaps with the aid of a sensor and solenoid. (EXAIR’s automated  Electronic Flow Control)

 

  1. Use intermediate storage of compressed air near the point of use.

Also known as secondary receivers, intermediate air storage is especially effective when a system has shifting demands or large volume use in a specific area. Intermediate storage is the buffer between a large demand event and the output of your compressor. The buffer created by intermediate storage (secondary receiver) prevents pressure fluctuations which may impact other end use operations and affect your end product quality. (EXAIR’s Receiver Tanks)

  1. Control the air pressure at the point of use to minimize air consumption.

This is a very simple and easy process, all it requires is a pressure regulator. Installing a pressure regulator at all of your point of use applications will allow you to lower the pressure of these applications to the lowest pressure possible for success. Lowering the pressure of the application also lowers the air consumption. And it naturally follows that lower air consumption equals energy savings. (EXAIR’s Pressure Regulators)

By increasing your awareness of the health of your air compressor system and implementing a PM program you can significantly reduce your costs from wasted energy and avoid costly down time from an out of service air compressor.

If you would like to discuss improving your compressed air efficiency or any of EXAIR’s engineered solutions, I would enjoy hearing from you…give me a call.
