We Lift Things Up and Put Them Down (Part 2): EXAIR’s E-Vac Vacuum Generators

A few months ago, I wrote here on the EXAIR Blog about my wife and I competing in our very first powerlifting competition. It’s a long and tiring process training for months for one single day, but to see all of your hard work payoff on the platform come competition day makes it all worth it. After competing on Saturday, we were both back in the gym the following Monday morning getting ready for the next one. Memorial Day weekend we participated in the Rivercity Barbell MAYhem meet in Northern Kentucky, another trophy for my wife, and another 2nd place medal for me. I’m beginning to see a trend here…. The entire day didn’t go the way I wanted it to, but I was pleased with a strong finish: a 500lb deadlift on my 3rd attempt to end the day. Exactly what I had in mind on the drive home in early January after our first meet.

After a full, long day of lifting stuff up and putting it back down, I was definitely ready to hit the bed right upon getting home. I could’ve saved myself quite a bit of energy and exhaustion by using one of EXAIR’s E-Vac Vacuum Generators. Although I’m fairly certain that would end in a quick disqualification…  

EXAIR’s E-Vacs are designed to take the difficult part out of lifting, placing, clamping, and mounting across a wide variety of parts and materials. EXAIR offers two primary styles of E-Vacs to serve your needs: In-Line E-Vacs & our Adjustable E-Vacs

The In-Line E-Vacs are a single stage, cylindrical units that are compact and easy to mount right at the point of use. They can be held in place by threading directly onto a compressed air line, or by the use of a mounting clip. We offer styles for use with porous materials, such as paper or cardboard, with vacuum levels up to 21” Hg and vacuum flows up to 18.5 SCFM. For non-porous materials, such as glass, we offer units with vacuum levels up to 27” Hg and with vacuum flows up to 15.8 SCFM.

Adjustable E-Vac

For applications that may have varying weights and sizes, we offer a line of Adjustable E-Vacs as well. With the simple loosening of a locknut and turning the exhaust, you can increase and decrease both the level of vacuum and the vacuum flow. This style is also an excellent choice for applications where large particulate may be present and can pass through the vacuum. We offer (4) different models with adjustable vacuum up to 25” Hg and vacuum flows up to 81 SCFM.

No matter what it is you’re trying to pick up, EXAIR has an E-Vac suited to the task. For help in sizing the appropriate vacuum generator for your application, feel free to give us a call. Hopefully by then I’ve figured out how to win one of these competitions, and I’m sure I’ll have a trophy case full of ‘em for my wife.

EXAIR’s Air Nozzles & Jets: The Engineered Alternative to Cheap or Homemade Blowoffs

If one of your goals is to reduce air consumption in your facility, look no further than EXAIR’s Engineered Air Nozzles & Jets. By upgrading your blowoff, cooling, and drying operations to use one of our Super Air Nozzles or Jets you can save as much as 80% of your compressed air usage when compared with an inefficient solution.

EXAIR’s engineered nozzles are designed to optimize your compressed air system by entraining ambient air along with the supplied air, providing maximum force on the target. Inefficient solutions are commonly used in the form of cheap, plastic nozzles and sometimes even worse, open pipes or tubes. An open copper pipe or tube, even if “flattened” as we’ll commonly see, wastes an excessive amount of compressed air. This wasted compressed air can create problems in the facility due to unnecessarily high energy costs and the pressure drop that can be experienced affecting other processes. In addition to simply using too much compressed air, an open pipe or tube will often produce sound levels in excess of 100 dBA. At these sound levels, according to OSHA, permanent hearing damage will occur in just 2 hours of exposure.

By simply replacing the open tubes/pipe or inefficient solutions with an EXAIR Super Air Nozzle, you can quickly reduce air consumption AND reduce the sound level. Sound level isn’t the only thing an OSHA inspector is going to be concerned about regarding an open pipe blowoff, in addition OSHA 1910.242(b) states that a compressed air nozzle used for blowoff or cleaning purposes cannot be dead-ended when using with pressures in excess of 30 psig. I don’t know if you’ve ever tried to use an air gun with 30 psig fed to it, but the effectiveness of it is dramatically reduced. This is why there needs to be a device installed that’ll prevent it from being dead-ended so that you can operate at a higher pressure.

EXAIR’s Super Air Nozzles are designed with fins that serve two purposes. They help to entrain ambient air from the environment, allowing us to maximize the force and flow from the nozzle but keeping the compressed air consumption minimal. In addition, these fins are what prevents the nozzle openings from being completely blocked off. Using an OSHA compliant compressed air nozzle for all points where a blowoff operation is being performed should be a priority. Each individual infraction will result in a fine if you’re unfortunate enough to be the victim of an unannounced OSHA inspection.

EXAIR carries a wide range of sizes and materials of nozzles, so you should have no trouble identifying one suitable for your application. Each is in stock and available to ship same day with an order placed by 2:00 ET. If the savings in compressed air alone isn’t enough incentive, some energy providers offer rebate programs for the implementation of an engineered compressed air nozzle. If you need help selecting the best nozzle for your process, give us a call. An Application Engineer is ready and waiting to help analyze your process and recommend the best option.

EXAIR’s Flat Nozzles Can Be Customized for Your Application

EXAIR’s Flat Super Air Nozzles provide a 1” or 2” wide airstream with hard-hitting force. All of EXAIR’s Flat Super Nozzles adhere to OSHA Standard 29 CFR 1910.242(b) for dead-end pressure, providing a safe and efficient method of delivering a strong blast of air.

The flow and force from the Flat Super Air Nozzle is adjustable by regulating the pressure supplied to it as well as by installing different thicknesses of shims. Thicker shims provide more force and flow, while a thinner shim will reduce the force and flow as well as the overall air consumption. This makes the Flat Super Air Nozzle and ideal solution for applications that may require variable force for different applications. Changing out the shim is fast and easy, check out this brief demonstration from one of my colleagues:

The nozzles are also available in your very own Blowoff System that can be customized to fit the exact application. You have the ability to put together the best combination of nozzle, Stay Set Hose, and Magnetic Base to suit your needs. Available with either a single or dual Magnetic Base and any of our Stay Set Hoses, there’s many different possibilities. To begin:

  1. Select the Air Nozzle you’ll need.

EXAMPLE: HP1125SS 2” High Power Stainless Steel Super Air Nozzle

  1. Then select the length of Stay Set Hose. They’re available in lengths ranging from 6”-36”.

EXAMPLE: An HP1125SS with a 24” Stay Set Hose would be an HP1125SS-9224.

  1. Finally, you have the option to also select a Magnetic Base if necessary. These are available with either a one outlet Magnetic Base, or Two Outlet which would include (2) separate nozzles. For a single outlet, change the second digit of the “added on” dash number to a “3”. For a two outlet, change that number to a “4”.

 EXAMPLE: An HP1125SS with 24” Stay Set Hose and Dual Magnetic Base is a Model HP1125SS-9424.

EXAIR’s Cabinet Coolers: No Maintenance, Simple Installation, Many Years of Trouble Free Operation!

I recently had the pleasure of working with a customer that was looking to expand their production capacity. They were duplicating an existing line due to an increase in demand and needed another Cabinet Cooler. The previous unit, HT4325-24VDC, had been installed over 20 years ago and was still functioning without any issues. This was long before he had started working with the company and they were unable to locate any order history with EXAIR to determine the appropriate model size to order so they quickly uninstalled it to help identify which model they had been relying on all these years.

HT4325 Cabinet Cooler – over 20 years old!!!

They installed the cooler and auto-drain filter that comes with the kit. The only maintenance they’ve had to complete for the system is periodically changing the filter element. The Cabinet Cooler has no moving parts to wear out and requires little to no maintenance so long as it is supplied with clean, condensate free compressed air.

Utilizing Vortex Tube technology, the Cabinet Cooler produces cold air from an ordinary supply of compressed air. This cold air keeps the enclosure free of debris and moisture and is easily installed in minutes through a standard electrical knockout. Here is a short video that shows just how simple it really is. The Cabinet Cooler Systems are available with Nema 12 (IP54) ratings and are also available in Aluminum, 303 Stainless Steel, and 316 Stainless Steel construction for Nema 4/4X (IP66) rated enclosures. For systems that are not able to be mounted on top of the cabinet, we also have Side Mount Kits available in Aluminum, 303 Stainless, and 316 Stainless.

These systems are available with cooling capacities of anywhere from 275-5,600 Btu/hr. To make things much easier for you, we offer a Cabinet Cooler Sizing Guide that will allow us to recommend the most suitable model for your cabinet. With a few quick measurements, we’ll be able to determine the exact heat load that we’ll need to dissipate and offer you a quick and easy solution. If you experienced heat related issues on electrical panels last year, contact an Application Engineer today and we’ll see to it that this summer your cabinets remain cool!
