Let’s Keep Things Clean: Advantages of the Flat Super Air Nozzle

Published on by John BallLeave a comment
Flat Super Air Nozzles have replaceable shims to vary performance.

A panel manufacturer was having some issues with black contamination affecting the powder coat paint.  They were using an overhead chain conveyor that would move the panels from the paint booth to the oven for curing.  At the end, the panel would be offloaded to a conveyor belt to move into storage for later assembly.  They were having quality issues with black specs that showed up on the gray paint.  They found out it was coming from the links from the overhead chain conveyor.  They contacted EXAIR to see if we had a solution for them. 

We reviewed the specifics of what was occurring in their application so I could understand better the nature of the problem. After evaluating a couple of options, I recommended two pieces of our model 1122, 2” Flat Super Air Nozzles.  This nozzle blows a 2” wide airstream with a powerful force to cover the width and depth of the chain links.  They were able to cut the flashing for the guard around the chain conveyor to blow the air.  One was located on the side of the conveyor, and the other was placed at the top of the conveyor.  The 2” Flat Super Air Nozzles were installed and oriented at a point along the travel, where there weren’t any panels on the hook supports.  This ensured that the debris was removed before the painting process began.  The issue was that debris mixed with the powder paint during application and then baked into the finish. The panels then had to be reworked or scrapped.  Once they installed the EXAIR Flat Nozzles, the quality improved immensely as they were able to remove the loose debris before raw panels were added to the conveyor.

To expand more on the EXAIR Flat Super Air Nozzles, they have a wide range of uses.  Their unique design utilizes a patented shim for improved efficiency, safety, and force range.   EXAIR has an easy way to change the shim to better suit different applications.  You can increase or decrease the force of the nozzle by just removing two screws and changing the thickness of the shim inside.  EXAIR offers a Shim Set to allow for adjustment to a range of forces to meet your needs and without overusing the compressed air.  Many times our Flat Nozzles are compared to plastic flat nozzles. Those nozzles do not have this capacity. They also tend to break when installed within harsh, abrasive or otherwise rough, industrial processes. 

If you have a “dirty” process, and you wish to blow it away in a safe and effective manner, EXAIR will have a nozzle for you.  We offer a variety of sizes, materials, and designs to best fit your application.  You can speak with an Application Engineer if you need more details.  The company above was glad that they did.

EXAIR’s Super Air Nozzles

Published on by Jordan T ShouseLeave a comment

Have you ever walked into a manufacturing facility during lunch, and it sounds like you’ve walked onto a plane full of snakes…? That’s a common issue across every sector of manufacturing. Compressed air is used for blowing off, cooling and cleaning everywhere you look. Below are the six steps to optimize your compressed air system. But today, let’s jump to step number 3 and see how upgrading those blow-offs with an engineered Safety Air Nozzle can help add to your bottom line.

If you’ve been tasked with reducing operating costs in your plant, upgrading your blow offs to EXAIR’s Engineered Air Nozzles & Jets might be just the ticket. When replacing a homemade or inefficient solution, EXAIR’s Super Air Nozzles can save you as much as 80% of your compressed air usage.

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 and pipe 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 used at 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 prevent the nozzle openings from being completely blocked off. Using an OSHA-compliant compressed air nozzle for all points where a blow off 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.

If you think a few Engineered Safety air nozzles will help add to your bottom line, give us a call. We have a full team of application engineers ready and willing to get you a solution to make your facility safer and save money!

Mag Bases and Stay Set Hoses

Published on by jasonkirbyLeave a comment

When selecting a blowoff solution, the direction of the airflow is crucial and is typically determined through experimentation. Once you identify the optimal angle for your engineered compressed air nozzle, it is essential to ensure its stability. This is where our Stay Set Hoses and Magnetic Bases prove invaluable, providing the necessary support to maintain the desired position.

Our Stay Set Hoses feature a memory function that prevents them from creeping or drooping unless physically adjusted, making them ideal for directing airflow precisely where needed. To ensure their longevity, it is important to adjust them correctly. Available in lengths ranging from 6 inches (15 cm) to 36 inches (91 cm), these hoses come with threaded connections, either with 1/4-inch NPT male threads on both ends or a combination of 1/8-inch NPT female and 1/4-inch NPT male threads. Constructed from reinforced synthetic rubber, they can handle a maximum pressure of 250 PSIG and operate effectively in temperatures of up to 158°F (70°C).

Mag Bases come with one or two outlets. Stay Set Hoses come in lengths from 6″ to 36″.

Our Mag Bases are designed for quick attachment to any solid steel surface, providing a robust pulling force of 100lb (45.5kg) to securely hold your blowoff device in place, whether positioned horizontally or vertically. They offer the convenience of easy relocation when adjustments are necessary. Available in three configurations—1-outlet, 2-outlet, and a 1-outlet swivel—these bases feature a 1/4 turn shut-off valve for straightforward control, ensuring efficient use of compressed air by preventing waste when not in use.

 If you would like to investigate these products further or have questions about Mag Bases and Stay Set Hoses, or anything regarding EXAIR and our products, please do not hesitate to reach out. We would love to hear from you!

VariBlast Safety Air Gun Overview

Published on by Russ BowmanLeave a comment

After mowing the lawn, I always blow the driveway & sidewalk off with a leaf blower. Then, before pulling the riding lawn mower back into the garage, I blow off the deck with the leaf blower too, and it always looks like it does a great job. The other day, though, I had to replace the drive belts, so I removed the deck and found an awful lot of grass trimmings had accumulated in the inner recesses. No matter how much air my leaf blower moves (and it moves a LOT), I would have needed a much more focused flow to get into some of those tight spaces.

Situations like this are EXACTLY what EXAIR Safety Air Guns – especially the VariBlast Precision and Compact models – are made for. Consider:

  • Tight, focused flow – the VariBlast Precision Safety Air Guns can be fitted with our three smallest, most focused Super Air Nozzles – Atto, Pico, and Nano:
Not only do they create the most focused airflow patterns, these Super Air Nozzles are also small enough to fit in pretty tight quarters themselves.
  • Hard-hitting force – VariBlast Compact Safety Air Guns can also be fitted with the Atto, Pico, or Nano Super Air Nozzles for the tightest airflow patterns, as well as several others if higher flow & force are required.
For more aggressive applications, VariBlast Compact Safety Air Guns with 1″ High Power Flat Super Air Nozzles can apply up to 1 pound of force.
  • Extended reach – the VariBlast Precision Safety Air Guns are available with 12″ and 20″ 316SS extensions, and the VariBlast Compact Safety Air Guns can come with straight rigid aluminum extensions up to 72″ long.
  • Chip Shields – regardless of whether you need extensions for extra reach, these can all be supplied with Chip Shields. These are especially useful (and are included as standard) on the VariBlast Compact Safety Air Guns with Back Blow Air Nozzles.
Atto Back Blow Air Nozzles can blow out recesses or holes as small as 1/4″ in diameter.
  • Operator control – this is the key feature of the VariBlast models. Most handheld airguns have spool valve-type triggers that are really just on/off operation. They can offer some crude amount of throttling, but the variable pull trigger of the VariBlast Safety Air Gun provides precise control, and they’re ergonomic to boot. Here’s a short video that shows just how precise the control is with a VariBlast Precision Safety Air Gun.

Compressed air isn’t cheap, and if you use cheap, non-engineered blow-offs, you’re going to pay WAY more to operate them than you have to. If you want to find out how the VariBlast Precision or Compact Safety Air Guns – or any EXAIR Intelligent Compressed Air Products – can help you get the most out of your compressed air system, give me a call.
