Dual Cabinet Cooler Systems consist of two Cabinet Coolers and a model 4908 Dual Cabinet Cooler Hardware Kit. This hardware kit will connect the Cabinet Coolers together for a single compressed air supply port. This video shows you how to assemble the hardware kit to the Cabinet Coolers, and then illustrates installing the Dual Cabinet Cooler System on an enclosure.

I recently noticed on my mortgage statement that I own more of my house than the bank does now. That made me feel good, and it also gave me pause for a moment of reflection on all the adventures I’ve had as a suburban American homeowner. Good times…then, another adventure happened:
I’m in the middle of a major (to me) construction project in our house. Now, if you’ve ever worked with drywall, you know that anything you do to it creates dust….sometimes in great volume. No worries, though – I’ve got a real nice portable wet/dry vacuum that makes light work of drywall dust & scrap. So, when I’m done for the day, I leave the area as dust-free and tidy as it was before (“tidy” is relative…there are two teenagers and a dog in my house.)
Anyway, the adventure happened last Saturday morning, when the basement sump high level alarm went off. I had to get the water out of the sump, and fast, so I could find out what was wrong with my sump pump. No problem…I’ve got that real nice portable wet/dry vacuum, right? That was full of drywall debris. So, I hastily dumped it into the garage trash can (making another mess I had to clean up later) and removed the particulate filter so I could drain the sump. Which it did, like a champ. It was a stuck float on the sump pump, which I remedied quickly, and all was well with the world again. At least in my (and my bank’s) almost 1/4 acre of it.
Speaking of the different things you can use vacuums for, I had the pleasure of talking with a caller the other day about industrial vacuum applications. When they wash down a particular area of their facility, they end up with puddles of water, mixed with lots of solid debris, all over the floor. They were using electric wet/dry vacuums (like mine) but had a recent scare involving a damaged power cord on a wet floor. Luckily, someone saw it before anything bad happened, but it made them think about other options…like compressed air operated Industrial Vacuums.
They looked at some dual Venturi systems, which would indeed replicate the function of their electric vacs, but at a considerable rate of compressed air consumption…over 100 SCFM (over 25HP worth of typical industrial air compressor load.) Their compressed air system simply didn’t have the capacity for this. They already had an EXAIR Reversible Drum Vac, and had plenty of capacity to run it since it only requires 19 SCFM @80psig (about 5HP worth of compressor load,) but it wasn’t greatly effective at picking up the solid debris. That’s where the EXAIR Chip Vac comes in to our story…it uses only 40 SCFM @80psig (about 10HP worth of compressor load) to clean up the solid debris that doesn’t get sucked up with the puddles of water & sludge that the Reversible Drum Vac takes care of.
And…(back to the title of this blog)…a Reversible Drum Vac AND a Chip Vac STILL cost less to purchase than the dual Venturi system they were looking at. Lower purchase cost. Lower operating cost. Two independent systems. That’s a win-win-win. If you have wet…dry…or wet & dry…messes to clean up, give me a call.

Last week I worked with a gutter manufacturer who was looking for a way to spray a light coating of vanishing oil on the rollers of a forming machine. Roll forming is commonly used when needing to maintain a constant and consistent shape or feature across the length of the part. In this particular case, a sheet of aluminum, used as a cover for the gutter, is fed into the machine where it passes over a series of dyes that bends “ribs” and punches small holes into the part to keep leaves or debris from settling on top, while allowing the rainwater to pass through the holes and into the gutter.
They were needing to apply the oil to the rollers because they were starting to see some irregularities in hole size as well as some deformities to the shape of the ribs due to heat being generated during the forming process. The customer was interested in using some type of atomizing spray nozzle in the hopes that providing an atomized mist of liquid may provide for a faster evaporation of the oil so there wasn’t much residue left on the part before packaging.
After further discussing the details, they advised that they were going to have the oil in a container about 12″ below the machine but didn’t have a way to pressurize or pump the liquid to the nozzle. Once again, EXAIR has the perfect solution with our 1/4 NPT Siphon Fed Atomizing Nozzles. These nozzles are the ideal solution where pressurized liquid isn’t available as they use the compressed air to the draw the liquid into the nozzle, up to 36″ of suction height, and mix it internally to produce a mist of atomized liquid spray. For this particular application, the Model # SR1010SS was a good solution as it provides a low flow rate of only 0.8 GPH and a tight spray pattern to focus right at the rollers to avoid any waste or overspray.
EXAIR offers an extensive range of Atomizing Nozzles that can be used for light coating applications, like above, or for wider coverage areas or higher flow rates. For help selecting the best option to fit your needs, contact one of our application engineers for assistance.

Last week I wrote about the use of the Atomizing Nozzles to create a fog for wet room curing of concrete samples poured during road construction. This week, I had the opportunity to work with another customer about concrete, but this time it was regarding the the manufacturing process. Invariably, I always learn something new , and for this interaction, it was the term ‘clinkers.’
Concrete is a composite material composed of coarse aggregate bonded together with a fluid cement that hardens over time. The customer I was working with was a cement manufacturer. Cement production is basically a 2 step process – 1) clinker is produced from raw materials and 2) cement is produced from cement clinker.
To make the clinker (step one), several powder raw materials are fed into a rotary kiln. The kiln is heated to very high temperatures, and when the materials are mixed and heated, new compounds are formed and hydraulic hardening occurs resulting in the formation of the clinker.
My customer needed a way to clean off the residual dust left on the transport belts, after the clinkers were transported to storage silos. Due to the high temperatures in the area, we focused in on the EXAIR Type 303 Stainless Steel model of the Super Air Knife, as it can withstand temperatures up to 800°F. The customer went with (3) of the Super Air Knife Kits, which include the Shim Set, Auto Drain Filter Separator, and Pressure Regulator w/ Gauge, for easiest installation with maximum functionality.
The Super Air Knife is a tried and true product for cleaning, drying, cooling and general blowoff for conveyors. And with widths up to 108″ available, any size conveyor can be handled.
To make cement (step two), the clinker is ground into fine powder with other ingredients including gypsum (calcium sulphates) and possibly additional cementitious (such as blastfurnace slag, coal fly ash, natural pozzolanas, etc.) or inert materials (limestone). It is then stored or packaged and ready to be made into concrete.
To discuss your application and how an EXAIR Super Air Knife can benefit your process, feel free to contact EXAIR and myself or one of our other Application Engineers can help you determine the best solution.
