The Case For The High Lift Reversible Drum Vac

If you need to fill -and empty – a drum with water, or water-like liquid quickly and easily, there’s really no quicker – or easier – way to do it than the EXAIR Reversible Drum Vac.  They’ve been around for decades, and are successfully used in a wide variety of applications.  The Reversible Drum Vac pulls a -96″H2O suction head on a 5, 30, 55, or 110 gallon drum, which makes it ideal for a number of typical Industrial Housekeeping or fluid handling applications.

EXAIR Reversible Drum Vac Systems come in a variety of sizes and configurations to meet the needs of most any application.

In cases where the liquid has a higher viscosity, or is below grade, the High Lift Reversible Drum Vac was developed with those exact situations in mind.  It generates a -180″H2O suction head, and comes with a 20ft vacuum hose.  Since its introduction, the High Lift Reversible Drum Vac has been successfully implemented in numerous uses where the extra suction head has been key:

  • A maker of bottled condiments (think barbecue sauce- or ketchup-like consistency) uses them to clean up accidents when bottles are overfilled, or a conveyor malfunction results in dispensing a bottle’s worth of condiment when there’s not a bottle under the nozzle.  The 20ft hose gives them the reach to service several production lines from one centrally located drum, and the two way pumping action allows them to easily pump the drum into their waste collection system.
  • A precast concrete company uses one for various cleanup applications.  The High Lift RDV‘s suction head is needed, in particular for their hydraulic oil leaks & spills.
  • A ferry operator uses one to clean out the engine room bilge.  They put the High Lift RDV on a deck above the engine room…the 20ft hose extends down to the bilge to pump it out, and when the drum is full, it reaches to the main deck so the drum can be emptied into their waste recycling company’s receptacle.
  • A construction company uses one to clean up the slurry created during concrete cutting operations.  The High Lift RDV is able to keep up with the slurry from even their largest saws, and the 20ft hose allows them to keep the drum conveniently out of the cutting area.
EXAIR High Lift Reversible Drum Vac Systems come in different configurations for 30, 55, or 110 gallon drums.

EXAIR Corporation has a variety of Industrial Vacuums to meet most any cleanup need.  They’re all compressed air operated, which means they have no electric motors to burn out, or moving parts to wear out.  If you’d like to find out more, give me a call.

Additional Benefits To The Adjustable E-Vac Vacuum Generators

The EXAIR Adjustable E-Vacs are available in 4 different sizes to fit whatever your pick and place, vacuum holding, degassing, or vacuum evacuation process may call for. These units have been used in a multitude of applications and the Adjustable factor makes them versatile enough to fit a production line with changing needs.

These are all examples of how an E-Vac pick-and-place system is just a solenoid valve away from automation.

The Adjustable E-Vacs have a few benefits that may go unnoticed if one is not keen to exactly how they are constructed and function. This sets them apart from many vacuum generators. When dealing with vacuum generator applications such as pick and place, having a part that is always the same is easiest. This is not always the case. Sometimes it is not just the dimensions of the part that changes, sometimes the material changes or even the surface finish of the part. This is where the ability to change from a porous to non-porous vacuum generator is extremely helpful. Generally this means the material of the parts getting picked up will allow air flow through them (paper, cardboard, wood) or not (plastic, glass). A porous vacuum generator will pull more flow through the part material to hold the vacuum, a non-porous vacuum generator will pull less flow and achieve higher vacuum levels.

To better understand the difference between porous and non-porous, we’ve written about that. Check out Tyler Daniel’s blog on the difference between the two here. The beauty of the Adjustable E-Vac is that it can easily convert from porous to non-porous with a simple adjustment. This is a great feature for a job shop that may change materials they are cutting or engraving on their machines and need to adapt in a moments notice for the job at hand. This could also reduce the number of vacuum generator variances a store room may need to keep on hand for a series of production lines and help to reduce the chance an incorrect model is installed on a machine due to fewer variants.

Adjustable E-Vac

Another benefit which can be helpful in a production environment that has an E-Vac picking up dirty or debris ridden material is that the Adjustable E-Vacs can be disassembled and cleaned. Picking steel sheets off a laser cutter in order to remove the scrap that has a volume of spatter / dust can cause an accumulation of debris on the internals of any vacuum generator. By unscrewing the plug from the body the Adjustable E-Vac can be easily cleaned and all passageways maintained at a level to offer continual performance.

No matter what, the adjustability coupled with minimum components and fastener free disassembly of the unit are two great features that can help minimize machine downtime, lower number of parts kept on hand for machines, and ensure optimal performance no matter what the requirement is for the vacuum generator. If you would like to discuss further, please contact us.

Vacuum Generators for Porous or Non-Porous Materials

EXAIR’s E-Vac Vacuum Generators are a simple solution for creating vacuum for a variety of different applications from: pick and place, clamping, chucking, lifting, surface mounting, and vacuum forming. Our In-Line E-Vacs are available in two different styles: porous or non-porous.

The material that you’ll be picking up will dictate which model is most suitable for your application. For porous materials such as paper or cardboard, we offer the low vacuum level, high vacuum flow vacuum generators. With vacuum levels up to 21” Hg and vacuum flows up to 18.5 SCSFM, this style generates more vacuum flow to overcome porosity and leakage. They can also be used to lift or hold delicate materials and prevent any warping, marring, dimpling, or disfiguring of the surface due to excessive vacuum.

Non-porous materials such as glass, steel sheet, and plastic are much more rigid and do not allow any of the vacuum flow to pass through the material. For these materials, EXAIR offers high vacuum units with vacuum levels of up to 27” Hg with vacuum flows up to 15.8 SCFM. These vacuum generators offer maximum holding capacity for heavy materials. Sizes are available with compressed air requirements as little as 2.3 SCFM at 80 PSIG and up to 30.8 SCFM for the largest and heaviest materials.

In addition to the vacuum generators themselves, EXAIR offers a variety of different accessories to help you build a complete system. To minimize the sound level and ensure you’re adhering to OSHA 1910.95, we have Standard Mufflers as well a Straight Through Mufflers. The Straight Through Mufflers offer the best level of sound reduction, up to 26 dBA!!

With no moving parts to wear out, EXAIR’s E-Vacs are virtually maintenance free when supplied with clean, dry compressed air. To maintain proper operation of your E-Vac, installation of an Automatic Drain Filter will remove any particulate and moisture from the air supply. In addition, oil removal filters are also available if your compressed air supply contains any oil as is common in many compressed air systems.

For pick and place or lifting applications, vacuum cups will be necessary. With a wide variety of different vacuum cups available: Small Round, Large Round, Oval, and Bellows, we can accommodate nearly any size or shape material. For heavier materials, round cups with cleats provide rigidity and ensure that the load remains stable. For applications on textured or uneven surfaces, Bellows style cups have convolutions that allow for the cup to quickly decompress when it touches the surface of an uneven part or material.

With all of the different options making a selection can seem like a daunting task. If you’re struggling to determine the most suitable E-Vac and Accessories for your application, give an Application Engineer a call today!

We Lift Things Up and Put Them Down: EXAIR’s E-Vac Vacuum Generators

Myself, my wife, and our coach/father-in-law

2020 certainly had its ups and downs. During a tumultuous year there wasn’t a whole lot of positivity to be found, but it wasn’t all “doom and gloom”. In the midst of the worldwide shutdown, my wife and I both took some of the extra time we had to focus on ourselves. Getting antsy with all of the time sitting at home, we decided to embark on a new fitness journey that would really push us to our limit. What started as just focusing on improving our health, quickly became a new passion. Just this past weekend we both competed in our first powerlifting meet. It was great to validate all of our hard work we’ve put in. My wife brought home the 1st place trophy for her weight class while I took 2nd in mine. I’m sure I’ll never live that down… All in all it was a great way to kick off the new year.

Here at EXAIR, we offer a whole line of products designed specifically to lift stuff up and put it down. EXAIR’s In-Line and Adjustable E-Vacs are a powerful compressed air powered vacuum generator. They’re a low-cost way to create a vacuum for a variety of different applications: pick and place, clamping, chucking, lifting, surface mounting, and vacuum forming are just some of the possibilities. Both the In-Line and Adjustable E-Vacs are available in a variety of different sizes and flows and can accommodate a wide range of applications.

In addition to the vacuum generators themselves, EXAIR offers a variety of different accessories to help you build a complete system. To minimize the sound level and ensure you’re adhering to OSHA 1910.95, we have Standard Mufflers as well a Straight Through Mufflers. The Straight Through Mufflers offer the best level of sound reduction, up to 26 dBA!!

For heavier materials, round cups with cleats provide rigidity and ensure that the load remains stable. For applications on textured or uneven surfaces, Bellows style cups have convolutions that allow for the cup to quickly decompress when it touches the surface of an uneven part or material.

The vacuum port of the E-Vac has an NPT thread, vacuum cups can be installed directly in this inlet. For applications where the vacuum cup(s) are remotely located, we offer polyurethane vacuum tubing as well as a variety of different fittings to connect them. Both 1/4” and 3/8” O.D. sizes are available in 10’ lengths up to 50’. Simply indicate the model number of the tubing and add the length with a “-“ at the suffix. In addition to fittings and tubing, vacuum check valves are also available. These can be beneficial if there is potential for fluctuations in the compressed air pressure or supply. In the event that there is a significant drop in pressure or loss of compressed air supply, the check valve will ensure that the load remains stable.

With all of the different options making a selection can seem like a daunting task. If you’re struggling to determine the most suitable E-Vac and Accessories for your application, give an Application Engineer a call today!
