New EasySwitch Vac Simplifies the Process of Vacuuming Wet and Dry Materials

 EXAIR’s new EasySwitch® Wet-Dry Vac simplifies the filter change process when switching from vacuuming a dry material to a liquid or vice versa. Utilizing minimal compressed air, the EasySwitch is a powerful pneumatic vacuum that is ideal for any application - wet, dry, light and heavy.

The fast and tool-less conversion to vacuuming liquids is done by releasing one latch, removing the filter element and securing the latch. Simply reinstall the filter into the lid assembly for dry materials. The EasySwitch is designed to handle the toughest of industrial cleanup jobs with ease. It rests upon any 55 gallon drum. With EXAIR’s patent pending design, the EasySwitch vacuum uses a standard or HEPA certified filter when vacuuming dry material.

The EasySwitch vacuum creates a powerful vacuum (at a quiet 79 decibels) without the need for electricity. Because the vacuum generator has no moving parts and uses no electricity, there is little concern for failed parts, motor failure or working with liquids associated with electric industrial vacuums. The CE compliant EasySwitch is just the latest addition to EXAIR’s large selection of Industrial Housekeeping products, including the Reversible Drum Vac, High Lift Reversible Drum Vac, Chip Trapper, High Lift Chip Trapper, Chip Vac, Heavy Duty Dry Vac and Heavy Duty HEPA Vac.

EXAIR Super Air Amplifiers: Saving Air, Saving Lives!

A customer developing a method of delivering air to trapped miners during a multi-man mine rescue mission. The federal government mandates that in the event of an explosion, miners must have a safe place to retreat for a minimum of 96 hours. This system will provide them with a supply of air during that period of time. In the initial stages, they had tried using some old venturis left over from a previous project. While this did work, they weren’t as effective or efficient as they needed. Through a little bit of research, they found EXAIR.

Instead of using compressed air as the source, they’re using cryogenic liquid air. That air passes through a series of cold plates and heat exchangers and gets to the Super Air Amplifier at about 70°F. This air is then carried into the chamber, giving the miners a source of clean air.

EXAIR Super Air Amplifiers utilize a patented shim design that allows the unit to entrain ambient air at a rate of up to 25:1 from the compressed air supply. This balanced outlet airflow minimizes wind shear, producing sound levels that are typically three times quieter than other air movers. The Super Air Amplifiers are supplied with a .003” slotted air gap and can be adjusted by replacing the shim with a thicker .006” or .009” shim.

Do you have a cooling or drying application that could benefit from a Super Air Amplifier? Contact an Application Engineer today to find out how Vivek Engineers can help you to save compressed air in your application!

Benefits and Options for Safety Air Guns

 

Throughout industrial environments, there are often manual cleaning or blow-off applications that are performed with compressed air. These operations vary in frequency, intensity, and how critical to the operation they may be.

When it comes to OSHA standards and comfort of operators, many of the solutions found in manufacturing do not meet the standards and are dangerous to operators.

This is where EXAIR steps in and focuses on the end application while coupling a high performing engineered solution with an ergonomic and safe handheld safety air gun. In other words, EXAIR safety air guns are safe, easy to use, and typically reduce compressed air consumption. Currently, we offer four types of handheld safety air guns.

The VariBlast Compact Safety Air Gun:

This is my personal favorite in our current lineup of safety air guns.  The compact size fits comfortably in the hands of operators. The multi-finger trigger with patented VariBlast function is easily controlled for extended periods of time. The VariBlast Compact Safety Air Gun also has two compressed air inlets. This gives the ability to plumb compressed air into the bottom 1/4″ FNPT port or the top 1/4″ FNPT which a safe way to run air hoses for virtually any work station. The 1/8″ NPT outlet permits enough airflow to operate up to our High Power 1″ Flat Super Air Nozzle all the way down to our Atto Super Air Nozzle.  The patented design also delivers variable flow from any of the nozzles attached to operate anywhere from a gentle breeze up to a forceful blast.

The VariBlast Compact Safety Air Gun can also be coupled with an extension up to 72″ lengths as well as the Chip Shield to meet or exceed OSHA standards for compressed air cleaning.

The Soft Grip Safety Air Gun:

                     

This safety air gun is the next step up in size and options as far as force and flow of compressed air go. The four-finger trigger and integrated hook design make this safety air gun ideal for industrial environments where a little more force is needed from the air to blowoff products.  The Soft Grip Safety Air Gun offers a 1/4″ NPT female thread inlet on the bottom and is available with up to an 1106 1/2″ Large Super Air Nozzle on the discharge.  This will deliver up to 60 SCFM of compressed air and provide 3.3 lbs of force from 12″ away.  The Soft Grip Safety Air Guns are also available with up to a 72″ extension and a chip shield.

Heavy Duty Safety Air Guns:

                   

The Heavy Duty Safety Air Gun is even more robust than the Soft Grip Safety Air Gun and showcases a 3/8″ NPT female inlet to provide enough airflow to operate up to our model 1106 Large Super Air Nozzle as well to provide 60 SCFM  of airflow and provide 3.3 lbs of force.  Extensions are available in lengths up to 72″ with the addition of the chip shield.

1" Flat Stainless Steel Super Air Nozzles Blow Rinse Water From Pharmaceutical Equipment

The customer was using a competitor's nozzles to dry two drums of a pharmaceutical spheronizer machine after cleaning the drum with water, but the nozzles were not able to dry the surfaces inside the machine. We replaced the competition's nozzles with Model 1126SS 1" Stainless Steel Flat Super Air Nozzles, mounted at a 10 degree angle to the outside of the drum. This created a vortex of air that was able to dry the drums in 30 seconds.

Model 1126 and 1126SS 1" Flat Super Air Nozzles

EXAIR’s 1" Flat Super Air Nozzles are highly efficient, unique flat air nozzles. Their patented design uses a special shim to maintain the critical position of the component parts. A precise amount of air is released through the thin slot, across a flat surface. The result is a wide, forceful stream of high velocity, laminar airflow with minimal air consumption and noise.

Cooling With Compressed Air: Air Knife vs. Vortex Tube Products

One of the popular applications for the EXAIR Super Air Knife is cooling. When mounted so that the air flow sweeps across the surface of a product, the laminar nature of the air flow works to maximize the contact time with the surface, which also maximizes the heat transfer…which means better product cooling than, say the turbulent air flow from a fan or blower.

Still, it’s common for us to get questions about how to provide even faster cooling.  Well, the two main variables in heat transfer are the time the air is in contact with the product, and the difference in temperature between the product surface and the air.

We’ve already touched on “time in contact”…sweeping the laminar flow across the surface at as low of an angle as you can, against the direction of travel, is ideal.  Combine that with the extraordinarily high air flow due to the entrainment level of the Super Air Knife, and you get an awful lot of air in contact with the surface, for a (relatively) long time.

The difference in temperature, though, is a little trickier to deal with.  Because the developed flow from the Super Air Knife is mostly entrained ambient temperature air from the surrounding environment, you’re at the mercy of that ambient temperature.  One of the most common question – of the common questions about faster cooling – is, can you feed a Super Air Knife with cold air from a Vortex Tube?  The answer is no, for two big reasons:

• The Vortex Tube’s cold flow can’t be back pressured, which would happen if you fed it through the plenum of a Super Air Knife and tried to make it come out the 0.002″ gap.
• Even if it did work, the entrained air which, remember, makes up most of the flow, is still room temperature…meaning the total developed flow is a lot closer to room temperature than however cold the air you fed the Super Air Knife would be.

If the surface area to be blown on, to effect the desired cooling, is suitably sized, a Vortex Tube can be installed at a low angle to sweep its flow across.  The cold air flow from a Vortex Tube can also be distributed to more than one point, to cover more surface area.  That’s exactly what we do with our Dual Point Hose Kits for our Adjustable Spot Coolers, Mini Coolers, and Cold Gun Aircoolant Systems:

In fact, both the Single and Dual Point Hose Kits have a variety of tips they can be fitted with for tighter, or broader, flow patterns:

In some cases, multiple Vortex Tube products can be used, and, in other situations, the cold air can be directed through a manifold of some sort:
