EXAIR FAQs: A Hidden Nugget of Information

The pneumatic industry is huge. Almost every manufacturing plant around the world uses compressed air in one way or another. EXAIR has manufactured Intelligent Compressed Air Products since 1983, and in that time we have gathered much information. We sorted this data and placed it in our Knowledge Base section for all to see. Now, if you have a compressed air system in your plant, EXAIR probably has information about usage, optimization, and application details where we were able to solve or improve the settings with cost savings, efficiency, and safety. In this blog, I will cover one section of the Knowledge Base categories; FAQs.

FAQ Page

FAQs, or Frequently Asked Questions, is a library of inquiries that our customers have asked in the past. We compiled this collection that end-users, resellers, OEMs and distributors asked; and, we placed them in one area to be found quickly and easily. The FAQ library is located under Knowledge Base (reference photo above). We separated the FAQs by product groups to find more information like maximum temperatures, pressures, viscosities, etc. This in-depth assortment of information can help to swiftly answer some obscure questions that may be important for your application.

RDV How It Works

As an example, I recently received a call from a customer requesting information about the Reversible Drum Vac. This product is a two-way pump that uses compressed air to transfer liquid in and out of steel drums. They do not have any motors to wear or electricity to work; so, they are very reliably and long-lasting. This pneumatic pump works wonderful for transferring coolants. But this customer wanted to know if it can transfer hydraulic fluids; and if so, how fast. I was able to direct them to our FAQ library. We found that it can pump 10 gallons/minute or 38 liters/minute of hydraulic fluid. They also noticed that the Reversible Drum Vac can pump even more viscous fluids, like 15W40 motor oil. It opened their eyes on the capabilities of the Reversible Drum Vac for other applications in their facility.

Of course, Application Engineers at EXAIR are always available to answer questions about our products or about your applications. But if EXAIR is closed and you want to buy right away, the FAQ section could be a great place to find that “nugget” for a quick answer.

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.)

Identifying Reversible Drum Vac or High Lift Reversible Drum Vac

This summer we rolled out a new High Lift Reversible Drum Vac. Today, I received a phone call trying to figure out what Drum Vac the customer had. This led me to write a blog, “How can you tell the difference between a Reversible Drum Vac and a High Lift Reversible Drum Vac?”

The first identifier on the High Lift Reversible Drum Vac is the blue and black label attached to the muffler (pictured below), the label on our standard Reversible Drum Vac is silver and blue.

High Lift Reversible Drum Vac Label

As time goes on the label may disappear from these rugged units after years of use. Our engineering team has had some forethought in this area, and we created a physical difference in the units that will not be removed, edited, or worn away. To confirm the identity of your Reversible Drum Vac, unscrew the body of the Reversible Drum Vac from muffler.

The High Lift Reversible Drum Vac will have a groove machined into the plug of the body. The Standard Reversible Drum Vac will be a smooth finish.

The High Lift Reversible Drum Vac doubles the lift of a Standard Reversible Drum Vac, which makes it great for any below grade liquid cleaning operations. The additional vacuum strength of the High Lift Reversible Drum Vac can be used to move viscous materials. Sludge, vegetable oil, and heavy motor oil can now be lifted from a coolant sump or trap at heights up to 15′ vertically. On top of this extra lifting capacity it features the same benefits as the Reversible Drum Vac. With no moving parts to wear out and no electricity required, it can operate safely and effectively for years.
