Memorial Day 2021

In the current time, Memorial Day for a lot of people is the start of summer, a day of barbecues, and outdoor recreation. Traditionally, Memorial Day is a day we take the time to pay tribute to the men and women of the armed forces who lost their lives serving our country.

Decoration Day, as it was first known, originated shortly after the Civil War and became an official federal holiday in 1971. Observing Memorial Day includes activities such as visiting cemeteries or memorials, holding family cookouts and walking in or observing parades.

Most of us will not attend any of the memorial services over the weekend.  I just hope we do not get wrapped up in the gala of an extended holiday weekend and forget those who made the supreme sacrifice.

Many of our cities and towns will have some Memorial Day ceremony. Some of the activities EXAIR employees will participate in include walking in a parade, distributing flowers on veteran gravesites with their 4H club and enjoying family and friends. We encourage you to find out what your community (or one near by) is doing and participate. At the very least, take a minute to think about those who fought for your opportunity to choose whatever you will do over this weekend.

Thank you to all of our lost defenders.

Sincerely,
The EXAIR Team

Heavy Duty Line Vac Solves Alumina Spillage Problem

Spilled alumina material which needs to be vacuumed and returned to the main hopper.

The image above shows spillage of small alumina particles at an aluminum manufacturing plant in South America.  This customer needed a method to vacuum the spilled material and return it to the main hopper.  The ideal solution needed to be compact, simple, and provide repeatable results.  All of these are key aspects of EXAIR Line Vacs, so we began discussing application variables to make a solution recommendation.

Whenever we consider Line Vac applications we always explore the following variables:

  •      Bulk density of the material
  •      Size of the material
  •      Conveyance height
  •      Conveyance distance
  •      Required conveyance rate
  •      Available compressed air supply

The spilled alumina in this application has a bulk density of 1.1 g/cm³ (~68.7 pounds/ft³) which needs to be conveyed to a height of 3.3m (~11ft.).  The conveyance rate is not mandated, but the alumina particles are rather small in diameter and the customer wanted to move as much material as possible in as little time as possible.  Compressed air is readily available at proper pressures and flows, so we were left to determine whether a Line Vac could be a viable solution.  Fortunately we’ve found success in transferring alumina with our Line Vacs in multiple applications before, so we were confident we could find a solution here as well.

The height of this application is 3308mm (~11ft.) – an easy conveyance height for an EXAIR Line Vac.

After exploring the specifics of this application we determined the best solution to be the 2” Heavy Duty Line Vac model 150200.  The 150200 Heavy Duty Line Vac can easily move the alumina to a height of 3.3m at an estimated conveyance rate of 11kg/minute (25 pounds/minute).  There are no moving parts to wear out, which means little to no maintenance and reliable performance each time the Line Vac is used.

Our local distributor assisted with product procurement and in-country technical support.  So even though this customer was in a different continent, we were able to quickly get them the assistance and products they needed to solve their problems.

Earth Day 2021

Happy Earth Day from EXAIR!

April 2021 marks the 51st anniversary of Earth Day and it will be observed both virtually and even in person in some locations throughout the world. For EXAIR, this year marks our 38th year helping compressed air users save compressed air energy and the electrical resources associated with generating compressed air. And the 37th year for improving our own efficiencies and processes in order to reduce waste. It is nice to begin to see a few events that have people gathering (safely, of course) to engage together for a positive cause. Over at Earthday.org you can find virtual and in person events to celebrate Earth in 2021. They present a global map for us to become aware of local clean up events, educational opportunities, conservation events and more. Check it out!

EXAIR remains committed to a minimal footprint and continues to focus on manufacturing our products with little impact and doing our part to help protect our environment. We are proud to manufacture efficient products and implement processes and programs throughout our facility to help use our resources wisely. We also recycle everything we possibly can – cardboard, paper, metal, wastewater, plastic. EXAIR also pays us to take some volunteer hours, some of us choose “green” events.

We manufacture and sell Intelligent Compressed Air Products that are specifically designed to reduce the use of compressed air throughout facilities.  On top of that, when you purchase an EXAIR product it will arrive in fully recyclable packaging and, in most cases, is made from a material that will be recyclable should it reach a point it is no longer useful.

Over the past years we continually look for improvement opportunities within our systems and processes. Recently we have…

  • Over the past year, EXAIR recycled 416 cubic yards of paper and cardboard.
  • Recycled 100% of our cardboard and mixed paper products. Of the waste we place into our trash dumpsters – 80% is recycled and 20% is sent to the landfill.
  • We recycle 100% of the metal scrap from our machining processes. The materials we recycle are aluminum, Type 303 and Type 316 stainless steel.  
  • Used our very own Chip Trapper Systems in our manufacturing areas to extend the water-soluble coolant life from 6 weeks per changeover to 6 months per changeover. Keeping our coolant clean allows us to minimize the total amount of wastewater we recycle each year.
  • Minimized our own compressed air use by 1 million cubic feet per year.
  • EXAIR continues to make improvements to the efficiency of our computers and computer servers which require fewer Kilowatt hours (KWH) per day.

EXAIR asks every customer if they accept digital invoices rather than requiring them to be printed and mailed.  We have been able to eliminate over 90% of all printed and mailed invoices. This helps to reduce our resources used as well as the amount of materials that are possibly turned into solid wastes at customer facilities. This also aids to reduces the gas and vehicles necessary to deliver all of these invoices by mail.

Adding to the efforts above, we continue to maintain RoHS compliance on all electronic products, as well as actively track our supply chains to ensure no Conflict Minerals are being sourced and used in our products.

If you have any questions on how we can help your facility reduce their volume of compressed air, contact us.

Thanks for reading the blog and enjoy your Earth Day!

How to Calculate SCFM (Volume) When Operating at Any Pressure

If you need to operate at a different pressure because you require less or more force or simply operate at a different line pressure, this formula will allow you to determine the volume of air being consumed by any device.

Volume Formula

Using the EXAIR 1100 Super Air Nozzle as our example:

1100

Lets first consider the volume of the 1100 Super Air Nozzle at a higher than published pressure.  As shown in the formula and calculations it is simply the ratio of gauge pressure + atmospheric divided by the published pressure + atmospheric and then multiply the dividend by the published volume.  So as we do the math we solve for 17.69 SCFM @ 105 PSIG from a device that was  shown consume 14 SCFM @ 80 PSIG.

higher

Now lets consider the volume at a lower than published pressure.  As shown it is simply the ratio of gauge pressure + atmospheric divided by the published pressure + atmospheric and then multiply the dividend by the published volume.  So as we do the math we solve for 11.04 SCFM @ 60 PSIG from a device that was shown to consume 14 SCFM @ 80 PSIG.

lower
