If at First You Don’t Succeed Try, Try Again!

Over the past few weeks I’ve been going back and forth with my phone provider over some technical issues I’ve been having with the device. After some troubleshooting, we were able to conclude that the antenna has likely become loose, leading to the phone periodically not receiving service. Naturally, we’re outside of the 1-Year “Warranty” period that covers a defective device. I paid my insurance deductible and received a “refurbished” phone the following day. Unfortunately, this refurbished phone was unable to take pictures with the front-facing camera. I know what you’re thinking, how on Earth can I take selfies without a front-facing camera? So it was back to the phone provider to get another replacement, fortunately this time they sent a brand new device.

There’s nothing more frustrating than trying to get something to work right out of the box, only to experience issues. Whenever a customer is having an issue with a particular product, there’s a certain progression that we go through in order to assess the problem and determine the root cause. In some cases it is something simple, others it can be a few individual problems that are compounding each other. I recently assisted a customer that was having problems with his 110 Gallon Reversible Drum Vac System. He was having difficulty pumping water out of a container and into the 110 gallon drum. He stated that he just received the unit and was unable to get it to work.

This is a call that we get from time to time, and is generally remedied pretty quickly. Our first step is to check the air pressure at the inlet of the Reversible Drum Vac while it is operating. We recommend an inlet pressure of at least 80 PSIG for proper operation. By installing a pipe tee with a pressure gauge directly at the unit, we can not only verify the inlet pressure but also that the Reversible Drum Vac is being supplied with an adequate volume of compressed air. If the pressure on the gauge begins to decrease once the unit is in operation, we can conclude that the volume of compressed air to the Reversible Drum Vac is insufficient. This can be due to the use of restrictive quick disconnect fittings, improper line size, or a compressor that is undersized.

If the air supply is sufficient, we then inspect the system for vacuum leaks. If the drum does not have a complete seal, the system will not function. If there’s no vacuum leak and there is an adequate supply of compressed air, the Reversible Drum Vac likely needs to be cleaned. It took us a few tries to get there but through a little bit of trial and error, we were able to determine that this was exactly the case in this scenario. Even though the system was new, it had been supplied with compressed air that was not properly filtered. Some scale, rust and debris from the customer’s supply lines made its way into the body of the Reversible Drum Vac, impeding the flow of air. Here is a video that shows the cleaning procedure for the Reversible Drum Vac. Over time the Reversible Drum Vac can accumulate debris inside of the plenum chamber. Regular maintenance of the unit will ensure that it stays within specifications for when it’s needed most!

If you have an EXAIR product that’s not performing as well as it used to, give us a call. One of the Application Engineers will be able to walk you through the steps to ensure that you’re getting the most out of our products!

Taking My Job home With Me (I Wish!)

Last week, as Mother Nature was doing her typical dance between warm, almost Spring like days and then quickly reverting back to her Winter ways, the southwestern Ohio area was hit with a powerful storm. Luckily, my neighborhood area was spared the really strong winds and tornadic activity that nearby areas experienced.  We did however receive a decent amount of rainfall.

Every Spring when the ground is still slightly frozen, the first good rain always leads to some water  leakage into my basement.  The water comes in through the gaps between the floor and the walls and even seeps up through some of the floor cracks.  I have my theories as to why it only happens in the spring, but I’ll save that for another day.  As the blog title says, I wish I had taken home a Reversible Drum Vac with me.

EXAIR  manufactures the Reversible Drum Vac (RDV) System, which attaches quickly to to any 30, 55, or 110 gallon closed head drum. The Mini Reversible Drum Vac has the same great performance and comes complete with a 5 gallon drum.  Coupled with the Spill Recovery Kit, using the RDV to vacuum up the rain water would have been a short and simple process.  Using a mop, towels, fans and a dehumidifier took much longer and still did not get everything dry.

30, 55 and 110 Gallon Reversible Drum Vac Systems

 

The compressed air operated Reversible Drum Vac System is a high powered vacuum that can fill a 55 gallon drum in less than 2 minutes, and with a simple turn of the a knob, the same stainless steel pump quickly empties the drum.  With no electric motor to wear out, or impellers to clog, the RDV is designed to work in industrial environments.  An automatic safety shutoff valve prevents the system from over-filling.

EXAIR also manufactures systems made for cleaning up solids, such as machining chips and other debris.

To discuss your application and how the EXAIR Industrial Housekeeping Products can be a benefit at your facility, feel free to contact EXAIR and myself or one of our other Application Engineers can help you determine the best solution.

Daylight Savings Time = Spring Is Coming!

This coming Saturday, 3/12/17, the U.S. will observe Daylight Savings Time, commonly referred to as “spring forward and fall back” here in the eastern states. On the second Sunday in March at 2:00 AM, we “spring” our clocks forward 1 hour to 3:00 AM and this lasts through November when we then “fall” back from 2:00 AM to 1:00 AM. The goal of the practice is to provide more daylight through the evening hours of the spring and summer months.

alarm-clock

Don’t be “alarmed”, warmer temps are coming!

For me personally, it means one less hour of sleep and now my 8 year old son tries to reason with me on why he can stay outside and play longer now on school nights. YAY! The time change also reminds us that Spring is almost here but really we can’t complain too much here in Cincinnati, OH as we have had a fairly mild winter to say the least. With the warmer temperatures coming and the extra hour of daylight, it’s time to start the proverbial “spring cleaning” around the house and yard. And trust me, with an active 8 year old and a soon-to-be 2 year old, I have more than enough maintenance items to keep myself busy.

Here at EXAIR, we understand the importance of keeping industrial areas clean and tidy to maintain steady production as well. Our full line of compressed air operated Industrial Housekeeping Products provide a fast, reliable and virtually maintenance free way to keep critical processes flowing smoothly. Take for example our Reversible and High Lift Reversible Drum Vacs, used to vacuum spent coolant or other liquids and deposit them to a standard closed head steel drum. Or our Chip Trapper or High Lift Chip Trapper, which filter out suspended solids in liquids and captures them in a reusable filter bag inside the drum. With the simple turn of a knob, all of these units can be “reversed” to a powerful pump, to empty the drum to another reservoir or collection device. For dry material handling we offer our Chip Vac system or for more abrasive dry material, like steel shot, the Heavy Duty Dry Vac. When it comes to dusty areas, we offer our Heavy Duty HEPA Vac, providing HEPA filtration or 99.97% at 0.3 micron. ALL of these products are available in 30, 55 or 110 gallon systems.

From now through May 31, 2017, by ordering one of the above systems, we’ll include a FREE Vac-u-Gun with your purchase. You will need to order using the special promo code.

Will an EXAIR Vacuum Work with This Material?

img_9239

Activated carbon pellets in need of vacuuming

At the heart of EXAIR’s dry vacuum systems are a modified design to our Line Vac air operated conveyors.  These units convert a compressed air supply into a powerful vacuum source with no moving parts and thus no components to wear out.  This, in turn, translates to an instantaneous vacuum supply that is both durable and maintenance free.

These aspects of our vacuum systems led a pharmaceutical research company in Macau to contact us about using a Heavy Duty Dry Vac in one of their applications.  The complete details of the application were proprietary, but information about the specific use was made available.

What this customer needed to do, was to vacuum activated carbon chips in batches of ~300kg (660 pounds) into a contained drum or bag.  The ultimate question in the application was whether an EXAIR Heavy Duty Dry Vac system can vacuum 300kg of activated carbon.  And, if it can, how long will it take?  To answer these questions we turned to a bit of data about the activated carbon, and the potential vacuuming rate of the Heavy Duty Dry Vac System.

Activated carbon has a bulk density of ~0.52 g/cm³ (~32.5 pounds/ft³), and the Heavy Duty Dry Vac can vacuum this type of material at a rate of ~30kg/min. or more (~66 pounds/min. or more).  This means that we’ll be able to vacuum the full 300kg of activated carbon in ~10 minutes!

But, where will it all go?

If we were to use a 55 gallon Heavy Duty Dry Vac, we could vacuum ~105 kg. (232 pounds) of this material before filling the drum.  But, if we use a 110 gallon system, we will double this capacity while keeping the performance and compressed air demand of the system exactly the same.

The multiple sizes of EXAIR vacuum systems provided a wide array of solution options in this application.  After discussing these options and receiving a request for distributor contact in China, we passed this customer over to our Chinese distributor.

Providing solutions for industrial applications is the forte of EXAIR Application Engineers.  It doesn’t matter if the application is here in the States, or overseas, we’re available for any questions our customers have.

If you’d like to discuss your application with an EXAIR Application Engineer we’re available by phone, email, or online chat.

Two Vacuums For The Price Of One

I recently noticed on my mortgage statement that I own more of my house than the bank does now. That made me feel good, and it also gave me pause for a moment of reflection on all the adventures I’ve had as a suburban American homeowner.  Good times…then, another adventure happened:

I’m in the middle of a major (to me) construction project in our house. Now, if you’ve ever worked with drywall, you know that anything you do to it creates dust….sometimes in great volume. No worries, though – I’ve got a real nice portable wet/dry vacuum that makes light work of drywall dust & scrap. So, when I’m done for the day, I leave the area as dust-free and tidy as it was before (“tidy” is relative…there are two teenagers and a dog in my house.)

For the record, the dog was more interested in the new hole in the wall than the teenagers.

For the record, the dog was more interested in the new hole in the wall than the teenagers.

Anyway, the adventure happened last Saturday morning, when the basement sump high level alarm went off. I had to get the water out of the sump, and fast, so I could find out what was wrong with my sump pump. No problem…I’ve got that real nice portable wet/dry vacuum, right? That was full of drywall debris. So, I hastily dumped it into the garage trash can (making another mess I had to clean up later) and removed the particulate filter so I could drain the sump. Which it did, like a champ. It was a stuck float on the sump pump, which I remedied quickly, and all was well with the world again. At least in my (and my bank’s) almost 1/4 acre of it.

Speaking of the different things you can use vacuums for, I had the pleasure of talking with a caller the other day about industrial vacuum applications. When they wash down a particular area of their facility, they end up with puddles of water, mixed with lots of solid debris, all over the floor. They were using electric wet/dry vacuums (like mine) but had a recent scare involving a damaged power cord on a wet floor. Luckily, someone saw it before anything bad happened, but it made them think about other options…like compressed air operated Industrial Vacuums.

They looked at some dual Venturi systems, which would indeed replicate the function of their electric vacs, but at a considerable rate of compressed air consumption…over 100 SCFM (over 25HP worth of typical industrial air compressor load.) Their compressed air system simply didn’t have the capacity for this. They already had an EXAIR Reversible Drum Vac, and had plenty of capacity to run it since it only requires 19 SCFM @80psig (about 5HP worth of compressor load,) but it wasn’t greatly effective at picking up the solid debris. That’s where the EXAIR Chip Vac comes in to our story…it uses only 40 SCFM @80psig (about 10HP worth of compressor load) to clean up the solid debris that doesn’t get sucked up with the puddles of water & sludge that the Reversible Drum Vac takes care of.

Reversible Drum Vac (left) and Chip Vac (right) – two EXAIR Industrial Vacuums for lower cost (purchase AND operation) than wet-dry combo air operated vacuums.

And…(back to the title of this blog)…a Reversible Drum Vac AND a Chip Vac STILL cost less to purchase than the dual Venturi system they were looking at. Lower purchase cost. Lower operating cost. Two independent systems. That’s a win-win-win.  If you have wet…dry…or wet & dry…messes to clean up, give me a call.

Reversible Drum Vac Services Ultrasonic Cleaner

The other day, I got a call from a customer who was frustrated with how long it took to change the solution out in their shop’s ultrasonic cleaners. Most folks are familiar with ultrasonic cleaners as the magic contraption that jewelry shops use to keep the gold and silver in their display cabinets all bright & shiny. My first thought was, this caller is NOT talking about those. Turns out, they come in MUCH larger sizes, and are used to clean a variety of industrial parts.

They were using a small submersible pump, but it was troublesome in that they could only use a 1/2″ hose (it was actually made for aquarium use,) and it took a long time to get 25-30 gallons out of their cleaners. Plus, there was always a little left in the bottom that had to be scooped out, because the centrifugal pump lost suction with about 1/2″ of liquid still standing in the bottom.

Since they were pumping it into one of the 30 gallon drums that they received the solution in, the EXAIR Model 6196-30 Reversible Drum Vac System (for 30 Gallon Drum) was an ideal choice. It used to take up to 15 minutes to empty the ultrasonic cleaner now takes about a minute, and they can get it all out, except for a small amount that has to be wiped up with a sponge.

Condiment Sauce Recovery Using The High Lift Reversible Drum Vac

Last week I worked with a food manufacturer who makes a line of specialty sauces, with consistencies similar to BBQ sauce or ketchup, who was looking to vacuum spills off their production floors. During production, they will sometimes experience an overfill during the bottling process, which results in the product spilling on the floor. Their current clean up method is to have an operator with a wash down hose, “thin” the sauce spills with water then direct it to a drain in the floor so it can be sent to the scrap tank. This was causing a few issues though, first, the drains have filter traps that were clogging regularly from not only the sauces but other particulate that may have been on the floor, causing environmental concerns for the plant. The other concern was the amount of water they were wasting to perform the clean up. My contact was the newly appointed maintenance manager and was tasked with trying to find a more reliable, economical way to remedy the situation. He was familiar with EXAIR as he had used some of our Line Vac Conveyors at his previous employer and knew we also carried a line of Industrial Vacuums but was unsure which product would be best suited for his needs so he reached out for assistance.

After discussing the details of the application, I recommended he use our High Lift Reversible Drum Vac System. The High Lift RDV is a liquid only vacuum that provides 180″ H20 vacuum and is able to handle thicker, more viscous fluids (up to 1400 cP) than our standard Reversible Drum Vac. With the ability to vacuum liquid up to 15′, the unit comes standard with a 20′ flexible vacuum hose and has no motors or moving parts to wear out. The system quickly installs to a standard closed head steel drum with available capacities of 30, 55 or 110 gallons. For spills, we offer our optional Model # 6901 Spill Recovery Kit which includes a 54″ ABS wand and 14″ double-blade squeegee that makes floor cleanup a breeze. After the material has been vacuumed, the unit can then be set to “empty” to pump the liquid back out to their waste tank so it can be carried away by their environmental recovery supplier.

The High Lift Reversible Drum Vac is able to pump thicker liquids from sumps or tanks up to 15 feet deep.
