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.

Improved Safety Benefits Employees & the Company

“Safety is Everyone’s Responsibility” is a slogan that companies around the world have adopted.

A refinery that processes palm oil from palm seeds had pipes throughout their facility to transport the oil. They would periodically have to clean the 10” diameter pipes as part of a maintenance program.  To do this, they would use a rubber plunger-like device called a pig to move through the pipe lines.  When they opened the piping system to install the pig, palm oil would leak onto the floor.  In their safety protocol, they would place adsorbent barriers around the spills and use a wet/dry vacuum to pick up the waste oil.  They would discard the liquid in a vat for disposal.  The wet/dry vacuum was limited in size to only hold 5 gallons because the operators would have to lift the container to dump the oil in the vat.  If the oil spills exceeded 5 gallons, then they would have to make multiple trips.  They wanted to get a better system as time was of the essence when you have oil on the floor.

6296 Deluxe RDV System

In speaking about their operations, they were needing to improve on their process and safety. I recommended the model 6296 Deluxe Reversible Drum Vac System.  This system uses a two-way pump and siphon tube that mounts into a 55 gallon drum easily without any modifications.  The pump uses compressed air, not electricity, to quietly generate a vacuum to a level of 96” of water. It does not have any moving parts, no motor or bearings to wear out, so it is very reliable and maintenance free.  The deluxe system comes with our Spill Recovery Kit for complete liquid pickup, a drum dolly, vacuum hose, and tool accessories with a holder.  In replacing their current system with the EXAIR Reversible Drum Vac, they could now vacuum a larger volume of liquid during excessive spillage without stopping.  Once the waste oil was vacuumed and contained, they could then just push their drum to the disposal vat.  With a simple turn of the knob, the two-way pump changes from a vacuum system to dispensing the waste oil into the vat.  This removed the need to lift any containers which could cause back damage to the operator.

As stated in the OSHA website, “Businesses spend $170 billion a year on costs associated with occupational injuries and illnesses — expenditures that come straight out of company profits. But workplaces that establish safety and health management systems can reduce their injury and illness costs by 20 to 40 percent. In today’s business environment, these costs can be the difference between operating in the black and running in the red.” Safety is everyone’s responsibility, and in using EXAIR products, you can do your part like the refinery above.

Choosing the Right Dry Vacuum – Chip Vac or Heavy Duty Dry Vac

A common question we get from our customers is, ‘I need a dry vac, should I use the Chip Vac or Heavy Duty Dry Vac.’  This is very good question, and we will take the time to better understand the application in order to best answer that question.

Both the EXAIR Chip Vac and Heavy Duty Dry Vac are designed to turn an ordinary 5 (Chip Vac only,) 30, 55, or 110 gallon open top drum into a powerful, industrial duty vacuum cleaner. Both are powered by compressed air, and have no moving parts to wear out or break, whereas the typical electrically operated system has motors and impellers that clog and break down quickly.  The Chip Vac and Heavy Duty Dry Vac are also quiet, at half the sound level of electric versions.

The Chip Vac is designed specifically for vacuuming chips. It creates a powerful direct flow that is ideal for metal, wood, and plastic chips.  Because it has a filter bag, in can also handle the occasional dusty material, and keep the surrounding air clean.

If the operation machines different materials, the lid can be removed from one drum and moved to another, to keep the materials separate for easy recycling.

The Heavy Duty Dry Vac was engineered to vacuum more dry material in less time with less wear. The hardened alloy construction resists premature wear and the increased power makes difficult jobs and harsh environments more easily handled.

The 110 Gallon  Heavy Duty Dry Vac provides maximum capacity for spill clean up

The Heavy Duty Dry Vac is ideal for abrasive materials such as steel shot, garnet, metal chips and sand, and is also useful for general purpose applications such as vacuuming floors, machines, work stations and machinery/equipment.

Like the Chip Vac, the Heavy Duty Dry Vac drum lid fits any open top drum, and can be moved from one drum to another facilitating recycling efforts.

Below shows the powerful performance of the Heavy Duty Dry Vac when considering large, heavy material and the increased performance you could expect.

Need an Upgrade? EXAIR has options.

Occasionally we field calls from customers who are currently using an EXAIR product but are looking to “upgrade” to something that might provide just a little bit “extra”. Such was the case recently when I was working with a customer who was currently using our Reversible Drum Vac to clean out their coolant tanks on their milling machines. The RDV was working great in the application but in an effort to gain more floor space, they were now going to store their coolant drums on their mezzanine, located around 10′ above the machining area so they needed something with more power to lift the heavy liquid coolant up to the mezzanine. I promptly suggested our High Lift Reversible Drum Vac. The High Lift Reversible Drum Vac provides up to 15′ of vacuum lift and mounts through the same, 3/4″ NPT threaded hole in the drum lid as their current unit. By purchasing a new High Lift pump unit only, and a 20′ vacuum hose, this customer avoided purchasing a completely new system (they  or other unfamiliar product. They simply replaced the pump unit into the 3/4 NPT bung of the existing drum, and swapped out the hose to meet their existing needs of higher lift.

The High Lift Reversible Drum Vac is designed to fit 30, 55 and 110 gallon, closed head steel drums.

This is just one example how EXAIR continues to offer new products to meet increasing customer demands. In fact, several other products have also been recently expanded or developed to demonstrate this commitment. Here is a short list showcasing some of our newer offerings.

The Chip Trapper System which filters suspended solids in liquid and traps them in a reusable filter bag inside the drum, is also offered in a High Lift version as well, providing the extra vacuum (180″ water column) discussed above, for elevated tanks or below grade sumps.

Maintenance Free And Proud Of It

Caller: Do you sell rebuild kits?
Me: Yes, but…why?

This is a WAY oversimplified summary of the start of a popular conversation that an EXAIR Application Engineer might have with a caller looking to restore a particular product to proper operation. Truth is, most of our products have no moving parts, and if you supply them with clean, dry air, they’ll run maintenance free, darn near indefinitely. We’ve documented this in specific cases regarding a Reversible Drum Vac from 1999, a Vortex Tube from 1987, and a Cold Gun from 1985.

Product & year of manufacture, from top left: Reversible Drum Vac (1999,) Cold Gun (1985,) Vortex Tube (1987.) All still performing within factory specifications.

Caller: So…DO you sell rebuild kits?
Me: Yes, but…only when necessary.

It’s important to note that none of the products mentioned above needed any parts replaced to return to service. Sometimes, a good cleaning is all that’s required. We can help you with a video tutorial if you want to know how to restore a Reversible Drum Vac, an Air Knife, or an Atomizing Spray Nozzle, for instance.  And we’re making new videos all the time for product maintenance, operation, tips & tricks, etc.

Caller (again): So…you DO sell rebuild kits?
Me: Yes, of course!  I mean, who wouldn’t sell rebuild kits for their products?

Take our Safety Air Guns, for example. We offer Service Kits, if the trigger and/or internal valve of a Soft Grip or Heavy Duty Safety Air Gun starts to wear or leak, it’s super easy to replace. We’ve also got replacement springs for the “fail shut” feature of the ball valve of a Super Blast Safety Air Gun. Just about anything else that could be wrong with a Safety Air Gun’s performance can be addressed by cleaning the nozzle.

We also recently added Rebuild Kits for our Atomizing Spray Nozzles to inventory. These contain all of the seals (and moving parts, for the No-Drip models) to restore an EXAIR Spray Nozzle to rated performance.

Keep your EXAIR Atomizing Spray Nozzle (left) in perfect working order with a simple & inexpensive Rebuilt Kit (right of the nozzle.) Contact an Application Engineer to select the one for your product.

For other products, we can also provide replacement gaskets & seals for the Reversible Drum Vac & Chip Trapper products, O-rings for the Line Vacs, Chip Vacs, and Heavy Duty Dry Vacs, new elements for Filter Separators & Oil Removal Filters…just to name a few.

Bottom line: if your EXAIR product isn’t performing the way it used to, give me a call.  It will be my pleasure to help you get it working like new, so that you can continue to get the most out of it.

EXAIR Chip Vac Removes Swarf and Keeps the Machining Center Running

The word of the day is “swarf”. Swarf is fine chips or filings of stone, metal or other material produced by a machining operation.

A company had four automatic profile cutting machines to cut aluminum stock.  They contacted me for help to improve their operation.  Each machine had a cleated belt conveyor to remove the swarf (or chips) from the cutting process.  Because the swarf was small in size, the chips could get around the edge of the belt and affect the conveying system.  Two of the four conveyors failed, and they wanted to find a better option to remove the swarf and keep the machines running.  They sent me a photo of the type and size of the swarf that was thwarting their conveying system.

EXAIR receives many calls about applications similar to this. I suggested the model 6193 Chip Vac System.  This assembly will fit onto a standard open-top 55 gallon drum which has a much smaller footprint than the conveying system.  The 0.1 micron filter allows for the air to escape and keep the fine particles inside the drum.  For this customer, once the drum was filled with aluminum chips, it was easy to rotate in an empty drum, sending the full drum of material to recycling.  The vacuum generator has no moving parts which makes it quiet, maintenance free, and long lasting.  It also creates a high vacuum level which was very useful when they attached it near the chip collection area.  The Chip Vac System was easy to install and it was very beneficial in keeping the machining area clean and running.

If you find that your chip conveying system is affecting your operations, you should contact an Application Engineer at EXAIR to see if we have a better and more reliable solution to remove your swarf.
