“Free” Ambient Air Entrainment w/ EXAIR’s Super Air Amplifiers

When working with a cooling application, many customers will immediately look to the Vortex Tube and Spot Cooling product lines. While this may be the best solution for some applications, cold air is not always the best method that we have available for cooling. EXAIR’s Super Air Amplifiers are very effective at reducing the temperature of a part without requiring cold air. The Super Air Amplifiers get their name due to their ability to entrain ambient air and “amplify” the supplied compressed air. You’ll often see us referring to the air amplification ratios achieved with our products. This is a ratio of the supplied compressed air relative to the entrained “free” air that comes from the ambient environment.

Due to their ability to entrain large amounts of ambient air, we can move a high volume of air across the surface of the part and quickly lower the temperature. I like to compare this to blowing on a hot cup of coffee just as it’s been brewed. The temperature of the air coming from your mouth is around 98.6°F, the same as your body temperature. Coffee can be as hot as 185°F when fresh. Due to the temperature differential between your breath and the hot coffee, we’re able to achieve a reasonable amount of cooling just by simply blowing across the surface. Typically, when the target temperature of the part or material needs to be around ambient temperature or higher; the best solution for cooling is going to be a Super Air Amplifier.

EXAIR’s Super Air Amplifiers achieve air amplification ratios ranging from 12:1 on our smallest units and up to 25:1 for our 4” and 8” models. EXAIR’s Super Air Amplifiers utilize a patented shim design to maintain critical positioning of component parts. This allows a precise amount of compressed air to be released at exact intervals toward the center of the Super Air Amplifier. This creates a constant, high velocity outlet flow across the entire cross-sectional area. Free, ambient air is entrained through the unit, resulting in high amplification ratios. The balanced outlet airflow minimizes wind shear to produce sound levels far lower than other similar air movers.

Super Air Amplifiers are supplied with a .003” thick shim that is ideal for most applications. Flow and force can be increased by replacing the shim with a thicker .006” or .009” shim. The flow of air is also controlled by adjusting the input pressure supplied to the amplifier. Higher pressures increase both the force and flow, while lower pressures decrease both force and flow. All Super Air Amplifiers are available in kits that come with a shim set as well as a suitably sized pressure regulator and auto-drain filter.

EXAIR has a solution for you if you need to move A LOT of air. Reach out to an Application Engineer today if you have an application that you believe could be served with a low-cost, simple solution!

EXAIR High Lift Reversible Drum Vac™ System: Overview

EXAIR High Lift Reversible Drum Vac Systems

Not all liquid vacuums are the same.  Have you seen motor burnouts, loud noises, single directional flow, and potential electrical hazards?  EXAIR manufactures a pneumatic venturi pump to remove all those issues; the High Lift Reversible Drum Vac System.  It does not have any moving parts to wear; a two-way action to fill or expel liquid from standard drums; and is quiet.  They only use compressed air to generate a powerful vacuum to lift liquid into a drum; and with a simple twist of the knob, it will push the liquid out.  And by using compressed air, no electricity is required, making it safe to use.  They work great for fluid transfers or liquid spills, and the High Lift Reversible Drum Vac can fill a 55-gallon (208L) drum in 85 seconds from 15 feet of lift.  And with the powerful vacuum pressure, it can move thick liquid with viscosity up to 1400 cps through 20 feet (6m) of hose.  How can this product be useful for you?  If you work with liquids in a cistern, underground tanks, higher viscous fluids, or pits; EXAIR has a product for you; the High Lift Reversible Drum Vac System.  They are reliable and simple to use; and it is why it was awarded the 2015 Product of the Year by Plant Engineering.  In this blog, I will go over the specifications and packages that EXAIR offers.

The High Lift Reversible Drum Vac has stainless steel construction for corrosion resistance.  It comes with a built-in safety relief valve to avoid over pressurizing and an internal float to stop any over-filling of the drum.  The air consumption is 43 SCFM (1,218 SLPM) at 80 PSIG (5.5 Bar), and it has a quiet noise level of only 83 dBA.  Systems are available in 30-, 55- and 110-gallon capacities (114L, 208L, and 418L respectively) in different packages.

30, 55 and 110 Gallon High Lift Reversible Drum Vac Systems

The Standard system will include the two-way pump assembly, shutoff valve, 20′ (6m) vacuum hose, a 90° quick release elbow, a standpipe, and an aluminum chip wand.  The standpipe is cut to length for the properly-sized drum (the drum is not included in this option).  The standpipe extends inside the drum to remove as much liquid as possible when emptying the drum. 

With a simple turn of the knob, the High Lift Reversible Drum Vac can fill or empty a 55 gallon drum

The Deluxe system will include all of the items shown above in the Standard system and adds a drum dolly, ABS spill recovery kit, (2) extension wands, crevice tool, skimmer tool and a magnetic tool holder.

The Premium system will include all of the items in the Standard System and adds the drum with lock ring and lid, drum dolly, ABS spill recovery kit, (2) different lengths aluminum crevice tools, skimmer tool, a magnetic tool holder and a 20′ (6m) compressed air hose.

Like I mentioned above, not all liquid vacuums are the same.  The EXAIR High Lift Reversible Drum Vac System is maintenance-free for long-lasting use in industrial environments.  We offer a 30-day unconditional guarantee for U.S. and Canadian customers if you wish to try them out.  And from now until May 31, 2022; EXAIR is having a promotion.  With a purchase of one of our Industrial Housekeeping Products, you will receive a Vac-u-Gun with a vacuum bag, a $133.00 value, with qualified purchases.   If you have any questions about the High Lift Reversible Drum Vac System or any of our other Industrial Housekeeping Products, you can contact an Application Engineer at EXAIR.  We will be happy to help you.

EXAIR’s Vac-U-Gun is THE Ideal Maintenance-Free Handheld Vacuum for Operators

Do you have workstations that require periodic cleaning and are tired of replacing electric vacuums? EXAIR’s Vac-U-Gun is a simple to use low-cost solution to a wide variety of industrial housekeeping issues. It’s constructed of a durable die-cast material and has no moving parts that’ll ever wear out or need to be maintained. Currently, EXAIR is running a promotion on the Industrial Housekeeping Products that includes a FREE Vac-U-Gun with any purchase of an Industrial Housekeeping Vacuum System.

In addition to being easy to use, the Vac-U-Gun is also more efficient than ordinary blow guns. By injecting a small amount of compressed air through directed nozzles, a vacuum is then produced on one end and a high output flow on the other. The amplified outlet flow through the Vac-U-Gun is 12 times the compressed air consumption of the gun.

The Vac-U-Gun is capable of both vacuuming material, as well as being operated as a blow gun. In vacuum mode, the work surfaces can be easily cleaned by vacuuming the debris away rather than blowing it off of the surface. Rather than simply moving the material around the shop floor, it can be contained and transferred to a waste receptacle using the 10’ vacuum hose, or straight into the filter bag.

Switching from vacuum mode to blow mode can be achieved in just a matter of seconds. To change the Vac-U-Gun from vacuum to blow mode, simply remove the threaded cap and change the orientation of the generator inside. Since the Vac-U-Gun has a large 1-1/4” diameter air outlet, it covers much more surface area in less time compared to traditional air guns. This can help to reduce the time needed for a variety of different blowing, cooling, or drying applications. Due to the nature in which the Vac-U-Gun entrains ambient air, it allows for more force and flow through the gun at a minimal compressed air consumption.

vac u gun kits

The Vac-U-Gun system is available by itself, or in one of three different kits. It can be used with or without the 10’ (3m) vacuum hose or the filter bag. Various vacuum accessories are included in the kits to accommodate a variety of different materials and applications. If you’re looking for a versatile gun that can help boost productivity in a number of applications within your facility, look no further than the Vac-U-Gun.
