Compressed Air Use in the Construction Industry

EXAIR uses many different methods to connect with our customers.  We have our website, social media, blogs, publications etc. We like to share solutions for some of the most common pneumatic problems in the industry.  EXAIR generated a large collection of application information where EXAIR products have solved problems and improved processes.  We organized them by Application and by Industry.  In this blog, I will show you how to use the Application database; specifically, for the Construction Industry.

Compressed Air Systems are considered to be a fourth utility within industries because they use a large amount of energy.  Whether it is an air compressor using fuel for portable units or electricity, it is important to use the compressed air as efficiently as possible.  This would apply to the construction industry.  From blowing off sheets of lumber to cleaning sites with an EXAIR Industrial Vacuum to cooling hot melt on window frames, EXAIR has a library of different processes in which we already accomplished these improvements.  We like to use the expression, “Why re-invent the wheel” at EXAIR.  If you are in the construction industry, it would benefit you to take a peek at the implementations where we already improved, made safe, and saved money.

Here is how you can find this library.  First, you will have to sign into EXAIR.  Click here: Log In.  Once you fill in the proper information, you can then retrieve a great amount of resources about EXAIR products that we manufacture.   The Application Database is under the Knowledge Base tab.  (Reference photo below).

At the Application Search Library, we have over one thousand applications that we reference.  In the left selection pane, we organized then in alphabetical order under two categories, Applications and Industry.   (Reference photo below).

Scroll down in the selection pane until you come to the sub-category: Industry.  Under this Sub-category, you will find three selections that are related to this blog: Construction; Construction and Mining Equipment; and Construction, Lumber.  You will find many applications that EXAIR has already improved and documented.

Why is this important?  If you are a plant manager or owner, the value of the Application Database can improve your current processes with pre-qualified results.  Within the construction industry, simple solutions can be found to address those “nagging” issues that you encounter every day.  For crisis situations and shutdowns, EXAIR categorized these applications in a way to reference quickly and easily.  And since EXAIR has a high volume of stocked items, we can get the product to you very fast; minimizing downtime.

In today’s market, companies are always looking for ways to cut cost, increase productivity, and improve safety.  EXAIR can offer engineered products to do exactly that.  With the “been there and done that” solutions already described in the Application Database; you can have confidence in finding a way in solving pneumatic issues.  If you do not sign up at www.EXAIR.com and take advantage of these offerings, you will be missing out on a great tool in optimizing your compressed air system.

Porous and Non-Porous E-Vac Vacuum Generators

Getting a vacuum from compressed air seems a bit like magic, but it works and it works well. EXAIR’s E-Vac® Vacuum Generators are compressed air powered, single stage vacuum generators. They are a low cost way to create vacuum for pick and place, clamping, lifting, chucking, vacuum forming and other applications.

The Low Vacuum Generators are ideal for ‘porous’ types of applications.  When we say ‘porous’ we are describing those processes where a lighter vacuum level combined with higher vacuum flows are needed. A good example of this is lifting a cardboard box. The cardboard is not air tight, and when you place a vacuum on it, air is able to be pulled through the cardboard. To maintain the vacuum level, the air needs to be able to be pulled through the cardboard and exhausted as fast as it is being pulled through in order to maintain the vacuum level. This requires higher vacuum flow and the design of the Low Vacuum Generator allows for the development of a good vacuum level and a high rate of vacuum flow.

The High Vacuum Generator is ideal for ‘non-porous’ type of applications. ‘Non-porous’ are those processes where the material is air tight, and no or very little air can pass through. Material such as glass, ceramic, and steel are ‘non-porous’. Because little or no air passes through, the need for high vacuum flow is not as important, and the highest of vacuum level can be achieved. A perfect vacuum is 29.92 in-Hg, and the High Vacuum Generator is designed to reach vacuum levels of 27 in-Hg, or a 90% vacuum level.

Both the Low Vacuum and High Vacuum Generators come in 7 different sizes, ranging from light to very strong vacuum capabilities, to match any application. Special Kits are  available as a way to experiment with an assortment of vacuum cups to determine the best configuration.

The EXAIR Chip Trapper™ System Extends Machine Coolant Life

Have you realized that you spend too much time cleaning out your CNC machine?  Do you find that It is messy and backbreaking work?  Do you spend too much money replacing the coolant in your system?  If you answer yes to any of these, EXAIR has a product for you; the Chip Trapper System.

EXAIR created this product to reduce the down time and extend the life of your coolant.  This device will save you money and time with productivity, coolant, and repairs.  In this blog, I will go over some of the features and benefits with the Chip Trapper Systems.

EXAIR offers two types, the Chip Trapper and the High Lift Chip Trapper.  They are designed to move fluid into the drum to be filtered, and to allow the clean fluid to be placed back into the sump.  The Chip Trapper works great for quick coolant cleaning at the floor level.  The High Lift Chip Trapper is ideal for cleaning viscous fluids as well as for reservoirs below the floor level.

Both types use a pneumatic two-way pump to move the fluid.  They come in three different drum sizes, 30 Gallon (114L), 55 Gallon (208L), and 110 Gallon (418L). So, you can clean large sump tanks with only one cycle through the cleaning system.  They come standard with a 5-micron bag filter that can hold over 5 gallons of material.

EXAIR can also offer filter bags in 5 other micron ranges from 1 micron up to 200 micron.  And if you are not sure on the other filtration ranges, EXAIR offers a filter sample pack, model 901060-SP, that includes one of each type.

Chip Trapper Cut Away

The Chip Trapper System includes the drum, the two-way pneumatic pump, a drum dolly, a directional flow valve, 10 feet (3m) of vacuum hose, 20 feet (6m) of compressed air hose, a chip wand, a shut off valve, and two additional filter bags.  All you need to do is to attach the Chip Trapper System to a filtered compressed air source.

The High Lift Chip Trapper offers a more powerful pneumatic pump which can fill a 55 gallon (208L) drum in 85 second from 15 feet (4.5m) below.  And, instead of the 10 feet (3m) vacuum hose, it will come with a  20 feet (6m) vacuum hose.

The unique features with the Chip trappers are the abilities to clean the CNC sump very quickly and with less mess.  Also, by using compressed air to pump the coolant in and out of the drum, it will aerate the coolant.  This will reduce bacteria growth and extend the life of the coolant. Thus, saving you money with those more expensive coolants.

Another benefit is that the pneumatic pump does not have any moving parts to wear out.  So, it will last you a long time without worrying about motor failures or loud noises.

You can watch the video of the operation here:

A list of some benefits that you will see if you purchase the Chip Trapper System is as follows:

  • The number of complete coolant change-outs are reduced.
  • The speed to get the CNC machines back operational to make parts.
  • Reduce the number of barrels of coolant concentrate per year.
  • Bacterial growth dramatically reduced as the Chip Trapper aerates the coolant.
  • Filter bags will remove the chip fines and some tramp oils keeping the coolant fresh.
  • Quiet and long lasting
  • A complete system that is easy to use.

As an added note, some CNC machines come with a spindle coolant feature.  This new technology helps in the need to increase speeds and feed rates.  The coolant is pumped to the top of the machine and fed directly through the spindle.  This type of spindle uses a rotary union which allows the coolant to the spindle as it spins at a high rate of speed.  The rotary unions are very expensive and costly to replace.

These spindles are very susceptible to dirty coolant.  If a seal within the rotary union begins to leak inside the machine, you will not be able to diagnose the problem until they have a machine failure.  The Chip Trapper with help eliminate this chance and keep your machine from an extreme expensive breakdown.

When your machine is not operating, your productivity is lost.  The EXAIR Chip Trapper Systems can be that product for you to get you back up and running is a short period of time, extend your coolant life, and keep the area clean and safe.  A win-win proposition in saving money and time.

For U.S. and Canadian customers, EXAIR offers a 30-day unconditional guarantee to try.  And, for a limited time.  an end-user will get a free EXAIR Vac-u-Gun, a $112.00 value, with any purchase of a Chip Trapper or High Lift Chip Trapper.

Vacuum Generator Accessories

In my last blog, I went over How to Choose/Build an E-Vac system, and you can read about that here–  The E-Vac’s are a compressed air powered, single stage vacuum generator, providing a low cost solution for creating a vacuum for many applications. Today, we will look at the many accessories that are available to complete a vacuum system best suited to your vacuum application.

For pick and place operations and hold down or clamping processes, we offer an array of Vacuum Cups. Available from stock are small and large Round, Oval, and Bellows styles. Round cups are best suited for smooth, flat surfaces.  Oval cups provide the most vacuum due to the larger surface area, making them ideal for lifting heavy loads. The Bellows style is best suited for textured or uneven surfaces, where the folds provide a collapsible area that allows the cup to compress and seal to the uneven surface.

For vacuum processes where personnel are nearby, there are two (2) types of mufflers available to reduce the sound level to comply with the limits OSHA Standard 29 CFR – 1910.95(a) has established. The EXAIR E-Vac Mufflers are designed so that the E-Vac exhaust is not impeded, so that the highest and fastest vacuum response is achieved. The Standard Muffler (for use with In-Line E-Vacs only) has a closed end and is best suited for vacuum draws that are free from dust and debris.  The Straight Through Muffler is open all the way through and is recommended for those vacuum draws where there will be dirt and debris, since it will not plug up. The Straight Through style offers the best sound level reduction, up to 26 dBA.

The vacuum port of the E-Vacs has an NPT threaded connection and with a suitable connector, a vacuum cup can be closely installed, minimizing the system air volume. When vacuum cups are to be remotely mounted, Push-In Connector Type Fittings of assorted styles are available along with the polyurethane tubing to make the installation and vacuum plumbing a cinch.

And finally, to get the best performance and maintenance free operation from your E-Vac, always use a source of clean, dry compressed air. We can help you do that with a wide array of Automatic Drain Filter Separators and Oil Removal Filters sized to pair up with the various E-Vac’s. Also available are Pressure Regulators, Vacuum Gauges, Manual Shut Off Valves, Solenoid Valves, and Compressed Air Hose.
