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.)

Another “Bucket And Ladder” Operation, Foiled By The Line Vac

Let me start by saying that EXAIR Corporation has nothing against buckets. Or ladders. We use them both here for a variety of tasks, and are very satisfied with them. But when they’re used together…that’s where we’re going to take exception. And we’re not the only ones.

I had the pleasure of speaking to an expert technician with a company that provides world class water recycling equipment & services. They use our Model 140200 2″ NPT Threaded Aluminum Line Vacs to move bentonite clay (an amazingly versatile purification & absorption media) from 50 lb bags into a hopper. It is then dispersed into a holding tank of oily water, where it removes the pollutants and impurities, allowing for clean recycling.  And, since they no longer have to carry it up a ladder and pour it in, it’s also safer and more efficient.

EXAIR Corporation is committed to being proactive about the way we impact the environment. Our Sustainability Plan details the way we do this in regards to our responsible consumption of resources, our conscientious waste recycling measures, and the comprehensive impact of our products…everything from materials & design, to their efficient usage, to packaging. So, when our products are used in  application geared toward like-minded goals, it’s a win-win-win. For EXAIR, our customers, and the environment.

This is one of many ways that EXAIR’s diverse line of compressed air products are not only making processes more efficient, but making the world a better place through dedication to being “clean and green.” If you’d like to know more, please give me a call.
