A Closer Look At The EXAIR Reversible Drum Vac Systems

Amidst the multitude of products that EXAIR offers, we have a full line of Industrial Housekeeping Products, our pneumatic vacuums.  Within this product line is the Reversible Drum Vac System. This system is a product that I personally encountered fresh out of college in my first job within the metal cutting industry. I would actually carry a standpipe, 10′ hose, chip wand, and reversible drum vac in a job box to every machine tool show as well as some larger machine repair jobs I was responsible for.

EXAIR’s model 6196 – Reversible Drum Vac System

At the time, I didn’t know it was an EXAIR product as it had been around for years before me and had seen better days, had been used thoroughly and all I knew was that I could empty a sump faster than anyone else that I saw anywhere in the shows or even the large sump evacuation systems some of these shops had that almost had to be towed around with a forklift.  This was a marvel to me as I had honestly been showed one time how to use it from another team member and I was able to grasp all the knowledge needed to operate (Not because I am a genius or anything, it’s just that simple). The few things I was not aware of is what the other options for the Reversible Drum Vac Systems were. All I knew is what I had when I worked at that company and didn’t know what kind of possibilities there were to expand our capabilities, so hopefully, this will help you see all the options.

While EXAIR currently offers four different types of liquid vacuums, they are all based on the Reversible Drum Vac or the High Lift Reversible Drum Vac. The Reversible Drum Vac itself is available in four capacities of drums and several options for each. The three capacities available are 5, 30, 55 or 110 gallon.

The 5 gallon is perfect for bench-top machines or small tests that are taking less than five gallons of liquid.  The system can still pull up to 96″ of H2O and discharges at an even faster rate than it vacuums which is 30 GPM.  The system includes the container, lid, 10′ vacuum/discharge hose, aluminum chip wand, Reversible Drum Vac, standpipe, quick connect,  spill recovery kit, and several other ancillary attachments to make any liquid reclamation job easy and quick. The Deluxe Mini Reversible Drum Vac system adds on a drum dolly which makes this an easy to transport compact and efficient liquid spill/recovery system.

 

 

The 30, 55, and 110-gallon capacity systems are available in a basic, deluxe, and premium system. The Basic includes the standpipe for a given size, 10′ vacuum/discharge hose, quick connect, aluminum chip wand, and Reversible Drum Vac.  The Deluxe System adds a spill recovery kit, drum dolly, magnetic tool holder, and other ancillary plastic tools. The premium adds the appropriate drum with a tight sealing lid, latch/bolt ring, 20′ compressed air hose w/ quick disconnects,  as well as upgrades plastic tools to cast aluminum tools.

If you would like to discuss which of these systems is going to fit your needs and give you the ability to fill a drum ta 30 GPM and empty it even faster, please contact me.

When To Use The High Lift Reversible Drum Vac vs. The Reversible Drum Vac

One of my favorite TV shows growing up was Home Improvement with Tim Allen. One of the most memorable parts of the show was when Tim’s character would always state that when doing a job you need … MORE POWER!!!

In real life and within a production environment this is not always true. More often than not more power equals waste and inefficient use of the resources at hand. I know, I sound a lot like Tim Allen’s counterpart in the show, Al Borland. Well, the truth is, Al was usually right.  Here at EXAIR, we offer two different types of Reversible Drum Vac, the standard unit and the High Lift RDV.

The Reversible Drum Vac System converts a drum and dolly into a mobile pumping system.

The standard RDV will pull up to 96″ of water column when in suction mode. This is ideal for water-soluble coolants or other water-based rinses. The unit is paired with a 10′ vacuum/discharge hose to ensure optimal performance. The RDV will fill a 55-gallon drum with water in 90 seconds or less when operated at 80 psig inlet pressure. It will then empty the same drum even faster by discharging liquid at up to 166″ of water column displacement. To do both of these operations, fill or empty the drum the RDV will utilize 19 SCFM of compressed air. This is easily supplied within most industrial applications where that amount of compressed air usage can be overlooked.

EXAIR’s High Lift RDV makes cleaning out pits up to 15′ deep easy and fast.

If Binford manufactured a compressed air liquid vacuum, it would be the High Lift Reversible Drum Vac. This is the, “More Power” version of the RDV and can pull up to 180″ of water column when in vacuum mode. This can pull water-soluble coolants up to 15 feet below grade for those large machining centers that sit over the top of a coolant pit or those large footprint machines where a 20′ hose is needed to reach into and around the parts of the machine to where the coolant or liquid is housed. Another application would be for oil-based coolants or other petroleum-based oils/higher viscosity fluids. This will still discharge liquids at 166″ of water column when in positive displacement. The unit will outperform its predecessor and that comes with higher utilization of compressed air. While operating at 80 psig inlet pressure the unit will consume 43 SCFM of compressed air. This volume of air is still easily located within most industrial environments and is still less than the amount demanded by competitive units that do not offer the reversible feature of the High Lift Reversible Drum Vacs.

When it boils down to it, the High Lift Reversible Drum Vac will perform every task of the standard Reversible Drum Vac and will perform the vacuum portion of those tasks all faster due to the higher level of vacuum. When this higher level of vacuum isn’t needed, when the sump is at ground level and the coolant or liquid is around the viscosity of 50 weight motor oil or thinner then the standard RDV will work ideal for the application and would be the most efficient method to get the job done. When the liquid is higher viscosity or below ground level trying to pull it up out of a pit then the High Lift Reversible Drum Vac is the ideal tool to get the job done. Again, Al Borland had it right, more power is not always needed, sometimes it is better to keep it efficient.

If you would like to discuss your liquid vacuum application or any point of use compressed air application, please contact us. (Heck, I’ll even talk about Home Improvement if you are a fan too.)

Line Vac Brings Additional Solution To Alumina Spill Recovery

Mobile spill recovery unit

In my last blog post I wrote about vacuuming alumina dust in an aluminum manufacturing plant in South America.  In that application we were returning spilled alumina to the original hopper so that processing could continue.

This same customer has an additional application to vacuum spilled material, but the new need is to assist mobile spill recovery vehicles (shown above) in vacuuming spills of varying volume. These mobile vehicles are effective for most of the spillage demands they can access, but there are times where additional vacuum is needed, such as when the spill location is beyond the hose length of the system.  In those scenarios additional vacuum hose can be added, but line losses render the performance too low to produce real results.  With this in mind, the end user looked for a point-of-use vacuum boosting solution, and thought about again using an EXAIR Line Vac.

Considering the potential use of a Line Vac, we approached this in the same way as any other pneumatic conveying application, gathering the required information to allow a proper model number selection.  As with the previous application we confirmed the following:

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

The spills in this facility are comprised of alumina dust with a bulk density of 1.1g/cm³ (68.7 pounds/ft³).  From the floor to the maximum height of the vehicle is a distance of 3.25m (~11ft), and conveying distances were in a range of 3-10 meters (10-30 feet).  The customer had no required conveyance rate, only a requirement to boost vacuuming capacity when needed.

With this information confirmed we were able to make a model number recommendation, the 2″ Heavy Duty Line Vac model 150200.  Adding the 150200 Heavy Duty Line Vac to this mobile spill recovery unit brings additional vacuum flow and conveyance of the alumina through a high velocity airstream, making mobile spill recovery efforts more effective.

If you’re in need of a pneumatic conveying solution, contact an EXAIR Application Engineer (1-800-903-9247).  We’ll be happy to help.

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.
