Product Overview – High Lift Reversible Drum Vac

Are you needing to move a thick fluid, move liquid farther or higher? Do you have a below grade sump or pit you’re looking  to empty? Then EXAIR has the solution for you, enter the High Lift Reversible Drum Vac. Like the standard Reversible Drum Vac, the High Lift RDV is a compressed air operated, liquid only vacuum with no moving parts or motors that can fail,  like those in traditional electrically powered vacuums. What separates the High Lift RDV from the traditional version is the higher vacuum it achieves which allows you to lift liquids up to 15′, move liquids up to 20′ and handle fluids with viscosity as high as 1400 centipoise.

The High Lift Reversible Drum Vac is a high powered vacuum able to lift liquids up to 15′ and fill a 55 gallon drum in less than 85 seconds!

The High Lift Reversible Drum Vac features a two-way pump constructed of stainless steel and a built-in safety relieve valve to avoid over pressurizing or over-filling the drum. Air consumption is minimal, at 43 SCFM @ 80 PSIG, while maintaining a low noise level of only 83 dBA. In “empty” mode, the HLRDV achieves a flow rate of 30 gallons per minute (water) to quickly empty the drum.

Systems are available in 30, 55 and 110 gallon capacities in 3 different variations:

The Standard Systems include the High Lift Reversible Drum Vac, shutoff valve, 20′ vacuum hose, standpipe, 90° quick release elbow and aluminum chip wand.

Model # 6195, 6195-30 and 6195-110

Deluxe Systems include all of the items shown above in the “Standard” System and adds a drum dolly, ABS plastic spill recovery kit, (2) extension wands, crevice tool, skimmer tool and a magnetic tool holder.

Model # 6295, 6295-30

And Premium Systems include all of the items in “Deluxe” Systems and adds the drum with lock ring and lid, heavy duty aluminum tools and 20′ compressed air hose.

Model # 6395, 6395-30, 6935-110

Adjustable Spot Cooler Provides Needed Cooling In Sunglass Lens Manufacturing

A little while back, I worked with a large eyeglass manufacturer on a sunglass lens cooling application. In their setup, they were dry cutting film-coated lenses with a router and after the lenses are cut, they are passed through several different rinse cycles and inspected for scratches or other damage. They were seeing a high number of reject parts and determined that the heat being generated by the tooling, was causing the irregularities. In an effort to alleviate the condition, they used a section of open flexible tubing to blow compressed air at the bit, which helped a little, but they were still concerned with the amount of scrap material.

I recommended they use our Model # 3825 Adjustable Spot Cooler System in the process. The Adjustable Spot Cooler incorporates a Vortex Tube to provide a temperature drop from the incoming supply air temperature. Using the temperature control valve, the exhausting air temperature and flow can be adjusted to fit the application. The system includes a flexible hose to focus the cold air to the desired area until re-positioned. The system also features a magnetic base that allows for easy mounting. By incorporating the filter separator included in the system, they can remove any moisture and/or contaminants in the air supply, relieving any concern with contamination or damage to the part.

Model 3825 Adjustable Spot Cooler System

People of Interest: Daniel Bernoulli – 2/8/1700 to 3/17/1782

Daniel Bernoulli was born in Groningen, Netherlands on February 8, 1700  and was part of a large family heritage of famous mathematicians – His father Johann Bernoulli, one of the first founders of calculus, his uncle Jacob Bernoulli and his older brother Nicolous. When he was only 7 years old, Daniel began to take an interest in mathematics but his father convinced him that there was no financial gain to be had in mathematics and recommended he focus his studies in business instead. Reluctant at first, Daniel would take his father’s advice under the one condition, that his father would tutor him in calculus and his theories of kinetic energy.

At 13 years old, Daniel attended Basel University where he studied logic and philosophy completing his bachelor’s degree by the age of 15 and earning his master’s degree just 1 year later. Over the years, Daniel’s relationship with his father was strained as a result of him plagiarizing his father’s findings. Eventually, his father passed without reconciling with Daniel. At 24, Daniel became a Professor of Mathematics  at a University in Venice but resigned from the position just 9 years later in 1733.

His most recognized mathematical contribution, Bernoulli’s principle, came in 1938 while performing energy conservation experiments, and he published the results in his book entitled Hydrodynamica . He discovered that when fluid travels through a wide pipe into a smaller, more narrow pipe, the fluid begins to move  faster. He determined that the volume or amount of fluid moving through the pipe remains unchanged but will conform to the shape of the pipe or container as it flows. He concluded that the higher the pressure, the slower the flow of the liquid and the lower the pressure, the faster the liquid flow.

The same principle can be applied to air. As air moves around an obstruction or object, it follows the profile of the part and begins to speed up.

Take for example our Super Air Nozzles. The compressed air exits the nozzle through a series of jets which induces a low pressure around the profile of the nozzle, drawing in ambient air. This entrainment of air, up to 25 times or more, results in a high outlet flow at minimal compressed air consumption.

Super Air Nozzle air entrainment

Many of the products offered by EXAIR incorporate this science which can lead to a more efficient operation by lowering compressed air demand ultimately reducing operating costs.

Need to Cool Tooling but Limited On Compressed Air? Consider the Mini Cooler

I recently had a chat conversation with a customer who was looking to cool the tooling on his CNC router, mill and lathe in his small machine shop. During the machining process, as the tooling would begin to heat up, it would warp the bit, causing irregularities in the finished product. In some cases the tooling was getting so hot, it would actually break, creating a safety concern.

He had reviewed some of our cooling products and was thinking of using our Cold Gun in the application but was concerned with the air demand. The Cold Gun consumes 15 SCFM @ 100 PSIG and provides a 50°F temperature drop (from supply temperature) with 1,000 Btu/hr. of cooling capacity. The problem was that his compressor only produces a little over 9 SCFM. I explained that the existing compressor would in fact be undersized as it doesn’t produce enough volume to keep up with the demand of the Cold Gun.

Model 3808 Mini Cooler System with Single Point Hose Kit, includes swivel magnetic base and filter separator to remove moisture and particulate from the air supply.

Due to the limited amount of compressed air available, our Mini Cooler System, Model # 3808, would be the better solution. The Mini Cooler also provides a 50°F temperature drop with a little less cooling power, 550 Btu/hr., but this system only requires 8 SCFM @ 100 PSIG, falling within the existing compressor’s output capacity. The Mini Cooler also includes a magnetic base as well as flexible tubing to direct the cold air to the desired location, making it easy to move from machine to machine.

The Mini Cooler is the ideal solution for small tool or part cooling, with minimal air consumption.

If you are considering an EXAIR product for an application or have additional questions about performance, contact an application engineer for assistance in making the best selection.

More Efficient Compressed Air Use Could Lead To Energy Rebates

The use of compressed air can be found in almost any industry and is often referred to as a “fourth utility” next to water, gas and electric. The generation of compressed air accounts for approximately 1/3 of all energy costs in an industrial facility, in many cases, it’s the largest energy user in an industrial plant. With an average cost of $ 0.25 per every 1,000 SCF used, compressed air can be expensive to produce so it is very important to use this utility as efficiently as possible.

Utility companies recognize the benefit of using engineered products to reduce compressed air usage, like the ones manufactured by EXAIR, and offers rebate incentives for making a switch. Our local utility provider here in Cincinnati, Duke Energy, offers a $ 20 incentive for each replacement engineered nozzle.

 

Our Model # 1100SS 1/4″ FNPT and Model # 1101SS 1/4″ MNPT Super Air Nozzles

In their specification, the nozzle must meet a certain volumetric flow rate (SCFM) at 80 PSIG operating pressure for a given pipe size. For example, when looking at a 1/4″ nozzle, the flow rate must be less than or equal to 17 SCFM when operated at 80 PSIG. Our most popular nozzles for “general” blowoff applications would be our Model # 1100 (1/4″ FNPT) or our Model # 1101 (1/4″ MNPT) Super Air Nozzles. These nozzles require 14 SCFM @ 80 PSIG so this would be the ideal solution to reduce the air demand and take advantage of the rebate.

Here at EXAIR, much of our focus is to improve the overall efficiency of industrial compressed air operating processes and point of use compressed air operated products. If you’d like to contact one of our application engineers, we can help recommend the proper engineered solution to not only save on your compressed air usage but also assist with possible energy rebates available in your area.

Increase Safety and Gain OSHA Compliance By Using An Engineered Solution

In 1972, the US Department of Labor’s Occupation Safety & Health Administration (OSHA) established Standard 29 CFR 1910.242(b) to reduce the outlet pressure to less than 30 psi, of an open pipe, nozzle, air gun, etc. when being used for cleaning. The intent of this directive was to prevent injury to operators. They determined that 30 psi was the pressure in which the skin could be broken if the device were dead-ended against the operator’s body, causing an injury known as an air embolism…the dead-ended force of the air, under pressure, breaks the skin and introduces air flow inside the body. This is a VERY dangerous condition which can quickly lead to serious injury, possible stroke or ultimately death.

While OSHA doesn’t recommend any type or manufacturer of device, they do provide two methods you can follow to gain compliance.

The first would be to reduce the operating pressure below 30 PSI, as shown in the below line drawing.  This, of course, limits the strength and usefulness of the exhausting air flow before it reaches the nozzle and before it is used upon the application.

 

The other method indicates using a nozzle which includes a pressure reducer or a relief device which will reduce the air pressure to less than 30 psi if the nozzle is dead ended. All of EXAIR‘s products are engineered to meet or exceed this Standard. In the case of our Super Air Nozzles, the air exits through a series of jets, recessed behind an array of fins, so the outlet holes cannot be blocked directly, any potential obstruction of the outlet air holes results in the air having an alternative route to avoid injury to operators and personnel. This allows the full pressure (the highest energy) to reach the nozzle and the application

Open air lines and homemade blow offs violate OSHA standard 1910.242(b) because of harmful dead end pressures. If you would like to discuss how EXAIR products can help you gain OSHA compliance to increase personnel safety and avoid costly fines, please give me a call, I’d be happy to help.
