Vacuum Generator System Selection – EXAIR E-Vacs

Published on by exaircorpLeave a comment

E-Vac Vacuum Generators are a highly efficient, versatile compressed air vacuum pump. Their versatility allows them to be adapted to many applications such as pick and place, clamping or vacuum forming. They’ve also been used in more unique applications like wood veneer pressing and basketball deflation.

EXAIR manufactures (3) types of E-Vacs – Low vacuum generators for porous materials, like cardboard, generating up to 21″ Hg with vacuum flows as high as 18.5 SCFM. Our high vacuum generators, designed for use with non-porous materials like glass or steel sheets, produce vacuum levels up to 27″ Hg and up to 15.8 SCFM of vacuum flow. The adjustable generators provide flexible vacuum performance, up to 25″ Hg and 81 SCFM,  which can be easily adapted to meet the application.

EXAIR E-Vacs provide instantaneous vacuum response, and are engineered for high efficiency to minimize air consumption.

 

When making a selection, there are a few key areas you want to consider:

Is the material porous or non-porous?

  • This will allow you to select the proper type of vacuum generator to fit the application and the type of vacuum cup best suited for the process.

 

What is the weight of the part and how will it be lifted?

  • If the part is being lifted where the vacuum cups will be positioned horizontally, like on top of a sheet of glass, you want to use a safety factor of 2 times the actual weight of the part. In processes requiring the cups be positioned vertically on the part, such as picking up a sheet of plywood and hanging it on an overhead conveyor, a safety factor of 4 would be used.

 

How many Vacuum Cups do I need?

  • Consider the quantity and placement to evenly distribute the weight for safely moving the material.
  • Depending on the maximum vacuum the generator produce, how much weight can each cup lift?
  • Make the cup selection per the following chart

 

Once you have selected the type and number of cups needed, you can then begin to look at which additional accessories items you might need.

  • Filters – supplying clean, dry air is key for maintaining optimal performance. An automatic drain filter  can be used to remove any water or contaminants in the supply line. If there is oil present, consider using an Oil Removal Filter.
  • Mufflers – help to reduce the noise level without restricting the airflow. We offer 2 different styles – Standard and Straight Through. Standards mufflers are a good choice where the supply air is clean and dry. These mufflers can only be used with the porous and non-porous generators. The Straight Through mufflers reduces sound levels by up to 26 dBA and are the better choice in processes where dirt or particulate may be present.
  • Tubing and Fittings – polyurethane tubing is available in 10′ sections up to 50′ for processes requiring the vacuum cups be placed in a location that wouldn’t allow for direct mounting to the NPT vacuum port on the generator or where multiple cups are needed. You want to keep the length of tubing as short as possible though for effective pickup and release time.
  • Check Valve – will maintain vacuum on the load if the supply pressure were to drop or be lost during operation.

I Love It When They Show The Math

Published on by Russ BowmanLeave a comment

In every math or science class I ever took – from high school Algebra I, to CHEM101 in college, or a variety of classified material courses in Naval Nuclear Power School – it was always good form to show your work. And by “good form” I mean “necessary to avoid an F.” I’ve found, through helping my teenage sons with their homework (whether they want me to or not, but that’s another story,) the same rules apply today. And rightly so.

My oldest is slightly (at least) more interested in athletics than academics. Sunday night, as I was going to bed, I saw him in the living room. His face was not obstructed by his cell phone and he didn’t have his headphones on, so I saw a rare opportunity for a real-time conversation. He was watching game 7 of the NBA Championship, and it was near enough to the end of the game that I figured I could watch it with him and not sacrifice too much desperately needed sleep.

If you watched the series, you saw some phenomenal play by both the Cleveland Cavaliers and the Golden State Warriors. If you saw the end of game 7, you saw “the block” – Cleveland’s LeBron James came out of NOWHERE to rob Andre Iguodala of a quick two points on a breakaway lay-up. During the obligatory replays, I kept thinking that what James had done might border on the physically impossible. Then, ESPN’s “Sport Science” reel put into perspective just how close to that border he came:

Now, we don’t have anyone who can chase down a professional athlete and jump 12 feet in the air to take a basketball away from him, but we DO have a staff of engineers who can test air blow off products and “do the math” on how much better a fit to your application an EXAIR Intelligent Compressed Air Product would be. Our Efficiency Lab service is free and tests your current product to provide you a report comparing air savings, noise reduction, force values and a simple return on investment.

In our defense, I believe we are MUCH better at this than LeBron James or Steph Curry would be.

Do you want to find out how much quieter and efficient an EXAIR Intelligent Compressed Air Product might be than what you’re using now?  Give me a call…you can try one of our products in your facility, or we’ll test one of yours in ours.

Tourney Time!

Published on by exaircorpLeave a comment

This week begins my favorite time of year – college basketball madness!

Basketball hoop
It’s Awesome baby, with a capital A!

Like many of us around the country, my fan loyalty resides with a relatively small, local college that has seen a lot of program growth in recent years – Xavier University. For example, during the 2003-2004 season, the team was ranked preseason top 11 in the country but stumbled along the way and found themselves at 10-8 with a pivotal game against their in state, conference rival. They ended up losing the game and the players held a “team only” meeting afterwards so the seniors could, let’s just say, “focus” the team on their goals. Whatever was said in that locker room worked, as the team went on to finish the regular season with a 9-1 record and win 4 conference tourney games in 4 days (first team to ever tackle this feat) to capture the automatic bid to the national field of 64, where they eventually lost by only 3 points in their first ever Elite 8, to a certain team from Durham, NC. (It was the REFS fault and no I’m not bitter LOL).

In 2008 the team was facing a similar challenge as they had lost several close games and were now again faced with needing to win 4 games in 4 days to get the automatic conference title bid. They went on to secure the bid and were able to reach the Elite 8 again for the 2nd time in 4 years but their run ended with a loss to the #1 seed in the region. The school has now joined a larger conference which is great for national notoriety and recruiting but also brings a higher level in competition, either boosting or damaging their tournament resume.

This year has followed suit to previous years as the team didn’t perform up to expectations and spent much of the latter part of the regular season on the proverbial “bubble”. After each win or loss, the prognosticators would move them from a “lock” to the “bubble”, or even more confusing, “still has work to do” category. All that mattered was just win and let the rest take care of itself. The team did just that as they went on to make the finals of the conference tournament but were easily handled by the first place team and eventually lost.

The selection committee has rewarded their conference affiliation along with conference tournament success and ranked them as a 6 seed for this years national championship tournament (a little high in my opinion but I’ll take it!) playing the winner of one of the play-in games.

Who knows what tournament success or failure lies ahead but that is what makes this time of year so awesome. Even when my team loses, there is always a local team, an underdog or the year’s “Cinderella” that grasps the country’s attention and makes it hard to root against them. Since we are in Cincinnati, many of our folks live in Kentucky and the Wildcats prove their wide reach among many of our Ohio based people as well. It makes the office banter and challenges and trash talk more interesting when pitting the hopes of a small “bubble” team up against a behemoth like Kentucky. We would be remiss not to mention the other behemoth with a huge fan base in this neck of the woods, Ohio State. We cannot forget our loyal base of University of Cincinnati Bearcats, who have provided us with some stellar employees, though not much of a basketball team this year (I’m a Xavier fan, remember?). And with the late breaking news from last night’s winning Dayton Flyer team, we have some solid regional representation in the tourney year.

Wow, now that I think about it, we’ll be lucky to survive the next few weeks without a bit of office bloodshed. At the very least, a small skirmish is certain to happen ;-).

Here at EXAIR we have a great team too! From the production team all the way up to management, we understand that we need to remain focused on our main goal – to satisfy YOU, our customer! We are always striving to get better by developing new products, testing existing products or maintaining near perfect (99.9%) on-time shipments.

To put our team to work for you, give us a call!

And to all who may be distracted throughout these next four days – Good luck to your team as well!

The E-Vac and The Basketball

Published on by Russ Bowman

crosstown classic

This Saturday is a big day for college basketball around here: the University of Cincinnati Bearcats will play the Xavier University Musketeers in their 81st matchup, in what is known as the Crosstown Classic. ESPN basketball analyst Jay Bilas once said “Cincinnati and Xavier have created a rivalry that is unparalleled when it comes to outright passion and civic division.” It’s so big, in fact, that the local TV station broadcasting the game in 1990 was one of the few stations in the country showing something other than the State of the Union address. THAT’S big.

I had the pleasure of assisting a caller with a big problem involving basketballs (and other inflatable sports balls) recently. They do custom printing on these sports balls, which need to be inflated to do the printing, but must be DEflated before shipping…this is especially important when there are a BUNCH of them…like when a vendor at, say, an event like the Crosstown Classic might be selling promotional basketballs with the Official Logo on them.

Anyway, they had rigged up a standard electric powered shop vacuum through a series of adapters to get to the needle that’s used to inflate/deflate the ball, but it took a while, didn’t fully the deflate the ball, and the electric motor burned up on them. Since a big part of their operation was inflating balls, they had compressed air available, and were interested in seeing if an E-Vac Vacuum Generator would work.

We supplied them with a Model 800008M In-Line Low Vacuum Generator E-Vac – these generate more vacuum flow than the High Vacuum models, and, since only needed to evacuate the air, this was ideal. They were able to easily adapt from the 800008M’s 3/8” NPT vacuum port to their needle, and it even made for a very convenient, quiet, hand-held operation.

I won’t be attending the Big Game this weekend – EXAIR’s family Christmas party is that day – but my support goes where my tuition money went: GO BEARCATS!
