Two Specialized Air Guns for Static Removal

EXAIR manufactures a range of Static Eliminator products that are all efficient, effective, and easy to use…none more so than the Gen4 Ion Air Gun. Consider:

  • It’s “plug and play,” all the way.  Connect the cable to the Power Supply, and hook it up to your compressed air system, and you’re ready to go.
  • It’s efficient and quiet.  The high velocity jet entrains an enormous amount of air from the surrounding environment, where it’s ionized and ready to eliminate static charge quickly and effectively.
  • Instant static dissipation, at your fingertips (literally) – squeeze the trigger to blow ionized air, anywhere you want (well, within the reach of the 10 foot cable, anyway.)
  • This is our rugged, industrial use model which can be seen in assembly, packaging, painting/coating and plastics processes.
Model 8493 Gen4 Ion Air Gun Kit comes with everything you need, right out of the box. Just add compressed air.

Again, the Gen4 Ion Air Gun is just one of our Static Eliminator products.  Another handheld Static eliminator is our Intellistat Ion Air Gun, this product is more geared towards clean room type applications.

EXAIRs’ Intellistat Ion Air Gun has earned a Class 5 Cleanroom Rating making it ideal for static elimination in cleanrooms for sensitive processes. There are manufacturing processes that require certain cleanliness standards for operation in such as scientific research, solar panel manufacturing or biotechnology industries. This means that any tool or material you use in this process has to meet a certain standard. EXAIR’s Intellistat was engineered to do just that.

EXAIR Intellistat Ion Air Gun

The Intellistat Ion Air Gun is a patented handheld air gun for static elimination in sterile environments and clean rooms. This lightweight tool provides rapid static decay with a simple squeeze of a short-throw trigger reducing 5,000 volts to 500 in under second. Furthering the Intellistat’s utility, it has now been awarded the ISO 14644-1 Class 5 rating for clean rooms and controlled environments making it the perfect tool for electronics manufacturing, testing facilities and laboratories.

The Intellistat is the ideal solution for static elimination in your sensitive processes. Learn more about the Intellistat as well as the rest of EXAIR’s large line of static elimination products at www.EXAIR.com or by contacting any of our Application Engineers.

Understanding Air Entrainment or Amplification Ratios and Air Knives

Super Air Knife has 40:1 Amplification Ratio, entrainment is illustrated as the curved blue arrows.

EXAIR’s Super Air Knife is the top performer among our engineered air knives and it dramatically reduces compressed air usage and noise when compared to other blow-off systems. The Super Air Knife delivers a uniform sheet of laminar airflow across the entire length of the air knife. Even at high pressure of 80 PSIG (5.5 BAR), the sound level is surprisingly quiet at 69 dBA for most applications.

One feature of the Super Air Knife is its Amplification Ratio, or the ratio of ambient air to compressed air within the forceful blast of air from the Super Air Knife. The design of the Super Air Knife entrains ambient air at an amplification ratio of 40:1 (ambient air to compressed air). Entrainment is defined in the simplest of terms as: to draw in and transport (something, such as solid particles or gas) by the flow of a fluid. The Super Air Knife design produces two low pressure areas where surrounding air is pulled into the primary compressed air stream and is delivered to your target. EXAIR’s Intelligent Compressed Air® products use the principle of entrainment to give you more air volume than just the compressed air being introduced from your air compressor.  This will maximize the force value for your application with the minimum amount of compressed air. Any pipe, manifold, or fitting can be modified to blow compressed air, however, these homemade blow offs will be very noisy and perform poorly when it comes to air entrainment, or amplification ratios. In contrast EXAIR’s intelligent compressed air solutions are engineered to be very quiet and use conservative amount’s of compressed air while maximizing the output volume through entrainment. 

Furthermore, the table below demonstrates the differences between blow-off systems and the efficiency of EXAIR’s Super Air Knife. You can see that the Super Air Knife outperforms all or most other options when comparing purchase price, sound level, maintenance, horsepower required and electrical costs.

The use of EXAIR’s Super Air knife not only save air consumption but you can notice the lower decibel rating which meets or exceeds OSHA Standard 29 CFR-1910.95(a) for maximum allowable noise exposure. If you have questions or need help with EXAIR’s Super Air Knife or any of our Intelligent Compressed Air Products please contact us and let us help you.

EXAIR Corporation Puts The “Safety” In Safety Air Guns

One of the most dangerous things you can do is depressurize a line full of a pressurized gas. If the charge pressure is high enough, it’s going to come roaring out, with tremendous force and velocity. Anything in its path is subject to that force & velocity. Objects small enough to become entrained in its flow can become hazardous projectiles. The noise it creates can be literally deafening. If the point of discharge is accidentally jammed against your body, the pressure can get through your skin. As if that wasn’t scary enough, the gas then has a free path inside your body…they call that an embolism, and it can kill you.

Why on earth would anyone want to do that on purpose? Well, it happens every day, in factories, businesses, and homes all over the world, when people operate compressed air operated blow off devices. Of course, there are numerous factors that can drastically reduce the risk of injury associated with compressed air blow off devices.

One of these is mandated by the government. The Occupational Safety and Health Administration (OSHA) regulates the outlet pressure of any compressed air device used in industry for cleaning purposes. Keeping the outlet pressure low mitigates the risk of puncturing the skin. There are various methods of compliance with this regulation:

  • Regulate the supply pressure to less than 30psig. This absolutely complies, but it severely hampers your ability to get much done, as the air flow will be too weak to blow off anything but lightweight debris, from a smooth, dry surface, with the device pretty much right up on top of it.
  • Use a device that provides a relief path for the air flow if it was to become blocked or obstructed. EXAIR engineered Air Nozzles are designed to do this…you can supply them with higher pressures but they provide a relief path for the air, meaning they can’t be blocked or dead-ended.
Regardless of the compressed air supply pressure, the design of EXAIR Super Air Nozzles prevents a dangerous pressure from developing at the outlet.

The same regulation – OSHA 1910.242(b) – also addresses the airborne projectile problem by mandating the use of appropriate chip guarding. There are a number of ways to do this as well…chief among these is personnel protective equipment (PPE). At a minimum, you absolutely, positively should be wearing safety glasses with side shields whenever you have a blow off device in your hand (and so should anyone working near you, for that matter). If an operator is blowing off small, sharp shards, an OSHA inspector is probably going to get grumpy if they’re not wearing a full face shield, long sleeves, and maybe even a durable apron. Alternately, the blow off device could also be fitted with guarding as well…something like the Chip Shields that are available for most EXAIR Safety Air Guns. These polycarbonate dish-shaped shields fit on a rigid extension between the Safety Air Gun and the Super Air Nozzle, and can be positioned at an optimal distance to keep solid debris and liquid being blown off away from the operator.

Chip Shields are available for most EXAIR Safety Air Guns (left to right): VariBlast Precision & Compact, Soft Grip, and Heavy Duty Safety Air Guns…
…and others. These are just a few examples of blow off devices that can be successfully fitted with an EXAIR Chip Shield.

Another OSHA Standard – 1910.95(a) is there to protect operators against that literally deafening roar associated with unregulated discharge of compressed air. While cross-drilled nozzles (most easily seen in the lower left hand image above) provide a relief path to keep the outlet pressure at a safe level if they’re dead-ended, they’re still for all intents & purposes, an open-ended blow off…and quite loud. EXAIR Super Air Nozzles reduce the sound level of their air flow by design…the entrained air (which makes them so efficient) also forms a lower velocity barrier layer in the flow, which makes them extraordinarily quiet. In fact, all EXAIR Super Air Nozzles except our largest High Force models comply with OSHA limits for 8 hour noise exposure limits. Most callers that we talk to about applications for those are in areas where hearing protection is mandated anyway…if you need more than 4 pounds of blowing force, you’re probably wearing ear plugs already.

If you use compressed air for cleaning, drying, blow off, etc., you really need to do it safely, and in compliance with published & established safety standards. OSHA WILL fine you otherwise, and, even worse, someone could get hurt. EXAIR Corporation is devoted to helping you get the most out of your compressed air usage, and safe use is key to that. If you have any questions about it, give me a call.
