EXAIR Reversible Drum Vac Fills A 55 Gallon Drum in 90 Seconds Flat, And Empties It Just As Fast

There are a few ways to get the liquid out of a drum:

  • You can use a pump.  Some pumps are even made to mount straight onto the lid of the drum.
  • You can siphon the liquid out, if you can get the drum higher than where you want to put the liquid.  And if you have the time.
  • You can turn the drum over.  I used to do field service in chemical plants…some of them had drum handlers on fork trucks that could pick up and tilt the drum to pour the liquid out.  Some of them pushed the drum over and simply let the liquid spill into a pit or below-grade sump.

But pumps break down.  Siphoning is finicky and slow.  I’m loath to knock the skills of the fork truck operator that can pour out a drum like a sommelier pours a fine wine.  And I’ll never forget the first time I saw an operator half-roll/half-dance a drum to the edge of that pit and let the liquid dump as he dropped it precisely where he wanted it…however, even in the context of the inner recesses of a chemical plant, it was simple, but inelegant.

EXAIR has an engineered solution that preserves the simplicity, though: the Reversible Drum Vac.  Thread the standpipe into the bung connection and the RDV itself into the vent, and that drum is now a two-way pumping system, able to be emptied via a 10 foot long Vacuum Hose in as little as a minute and a half.  Turn the knob on the RDV to switch modes, and you can fill that same drum just as fast.

With a simple turn of the knob, the Reversible Drum Vac can fill or empty a 55 gallon drum in 90 seconds!

 

 

 

 

 

 

The EXAIR Reversible Drum Vac Systems come with a variety of configurations and options:

  • Made to fit an existing 30, 55, or 110 closed top steel drum in good condition.
  • Mini Reversible Drum Vac System comes with a 5 gallon drum.
  • Deluxe Systems add a Drum Dolly and a set of tools.
  • Premium Systems add a drum (30, 55, or 110 gallon,) an upgrade to Heavy Duty Aluminum Tools, and a 20ft compressed air supply hose with shutoff valve and pressure gauge.
  • High Lift Reversible Drum Vacs generate a suction head of 180″H2O for maximum lift.  They’re also specified for higher viscosity liquids.

Below is a great video that showcases just how easy it is to from installing the Reversible Drum Vac to using the Reversible Drum Vac and just how fast the RDV operates.

If you’re looking for a fluid handling solution for liquids in drums, give me a call and we’ll talk about which Reversible Drum Vac System is right for you.

Siphon Fed Atomizing Nozzles Selection

If you follow along with our blog, you will notice that we have recently published a few entries relating to our Atomizing Nozzles. Today, I would like to continue this trend and focus on our Siphon Fed Atomizing Nozzles.

When recommending an Atomizing Nozzle for a particular process, we try to obtain as much “general” information as possible about the application, such as:

  • What type of spray pattern do you need?
  • How wide of an area needs to be covered?
  • What kind of flow rate needs to be achieved?
  • Is the liquid source pressurized?
  • What is the viscosity of the liquid?

While all of this information is going to help simplify the selection process, when we get a reply that the liquid isn’t pressurized, the choice becomes a little less complicated.

Our Siphon Fed Atomizing Nozzles are the preferred solution in applications where a pressurized liquid source isn’t available. With a steady supply of compressed air, these nozzles are able to draw the liquid into the nozzle with suction heights up to 36″ for our 1/8″ NPT and 1/4″ NPT nozzles, and up to 24″ for our larger 1/2″ NPT Models. They can also be gravity fed as well.

1/8″, 1/4″ and 1/2″ FNPT Sizes Available

These nozzles mix the fluid internally and are capable of handling viscosity up to 200 centipoise. Depending on the size of the nozzle and supply air pressure, flow rates can range from 0.4 GPH up to 60 GPH with either a round or flat fan spray pattern. There is also an adjusting valve for more or less liquid flow as needed to fit the demand of the application.

We also offer these nozzles with our patented No Drip feature which positively stops the liquid flow when the supply air pressure drops below 30 PSIG, eliminating the need for any additional valves or supply lines.

1/2″ NPT No Drip Model # SR6010SS

If you have an application requiring a fine mist of atomized liquid, give me a call at 800-903-9247.

A Lot Can Happen In Five Years

Five years ago, I wrote a blog about my (then) 11 year old son’s first-ever week away from home at Boy Scout Summer Camp. He’s departing again this weekend, but his troop has decided to venture “out of Council” this year, to Camp Howard W. Wall…it’s on the south coast of the island of St. Croix, in the US Virgin Islands.

They met last week to cover the final (and finer) details of international travel, flight schedules, logistics, etc., and activities…Camp Friedlander has a “blob:”

But Camp Wall has an OCEAN:

Just to put the distance into perspective...
Just to put the distance into perspective…

I’ve been thinking a LOT about the changes I’ve seen in the wide-eyed kid I dropped off at a camp that I drive past twice a day, and the smirking teenager that I’m driving to the airport on Sunday morning. And those changes are providing perspective on not only how fast those five years have passed, but how much can happen in that span.

In 2011, I was a wide-eyed “Dread Newbie” at EXAIR.  One of my very first meetings with the rest of the gang was to be trained on our brand new Atomizing Spray Nozzles…we only had three styles to choose from, but two of them came in four distinct models, and one came in FIVE. They were ALL Internal Mix, because hey, who doesn’t like the maximum range of adjustability that comes with being able to vary your flow rate and spray pattern size by adjusting liquid AND air supply pressures?

OK; it turns out that was just the beginning…within the year, our Engineering Department had developed:

External Mix – three styles, thirteen distinct models, to allow for independent adjustment of flow rate (by liquid pressure) and spray pattern (by air pressure.)

Siphon Fed – two styles, seven distinct models, that could be siphon OR gravity fed, for situations where it’s not practical to pressurize the liquid supply.

And, four years after that, looking back, it seems like THAT was just the beginning…we now have:

*Two sizes – the original 1/4 NPT and the new(er) 1/2 NPT.
*Sixteen styles – each available with our No-Drip option (so technically I guess we have thirty-two)
*Forty-five distinct models – we’ve got a flow rate/spray pattern combination for just about any application

And, like the rest of our catalog products, they’re all in stock, ready to ship today, on time, like we do 99.97% of the time…that’s actually one thing that HASN’T changed in the 17 years that we’ve been keeping track.

If you’d like to talk about Spray Nozzles…or any EXAIR products (old or new,) give me a call.

No Drip Atomizing Nozzle Improves Deep Drawn Metal Process

The other day, I had the pleasure of helping a caller select an Atomizing Spray Nozzle for a particular application. They needed to apply a thin, quick drying coat of vanishing oil to the inside diameter of a round, deep drawn metal part. They were currently flooding the ID with it, and the part had to sit overnight to dry.

Since it was a cylindrical hole, it sounded like an ideal application for a Round Pattern nozzle, and, since they didn’t have an easy way to pressurize the oil source, we selected a Model SR2040SS No-Drip Siphon Fed Round Pattern Atomizing Spray Nozzle. By adjusting the siphon height and air pressure applied, they were able to quickly achieve the desired flow pattern and coating thickness.

Now, they’re able to take the part directly to the next step in their fabrication process, without the overnight drying cycle.
