New EXAIR Product Alert: Introducing the TurboBlast Safety Air Gun

Published on by Russ BowmanLeave a comment

For almost 40 years now, EXAIR Corporation has been devoted to a singular goal of providing quiet, safe, and efficient compressed air products for industry. In that time, our product offering has grown considerably…and it’s just taken another leap. I offer for your consideration, dear reader, the TurboBlast Safety Air Gun:

Five different Nozzles, three different extension lengths, optional gate valves give a great deal of flexibility in our newest product line offering.

Starting at the “business end”, these use our tried-and-true High Force Super Air Nozzles. With up to 23 pounds (10.43 Kg) of applied force, these are among the hardest hitting compressed air products on the market. That’s almost 28 times the force of our standard Super Air Nozzle, and is ideal for large area cleanup, slag or flash removal, blowing off stubborn debris & liquid, etc. To protect the engineered Air Nozzle and ensure long life, we’ve included a replaceable protective guard, preventing damage from incidental contact in the aggressive applications these are aimed at. Five different Super Air Nozzles are offered:

  • 3/4 NPT (Zinc Aluminum or 316 Stainless Steel)
    • Consumes 91 SCFM @80psig
    • Applies 4.5 lbs of force @12″ from target
    • 23″ wide pattern @48″ from target
  • 1 NPT (Zinc Aluminum or 316SS)
    • Consumes 135 SCFM @80psig
    • Applies 6.6 lbs of force @12″ from target
    • 24.5″ wide pattern @48″ from target
  • Model 1116 1 NPT (Zinc Aluminum only)
    • Consumes 188 SCFM @80psig
    • Applies 9.4 lbs of force @12″ from target
    • 26″ wide pattern @48″ from target
  • Model 1118 1 NPT (Zinc Aluminum only)
    • Consumes 300 SCFM @80psig
    • Applies 15 lbs of force @12″ from target
    • 28″ wide pattern @48″ from target
  • Model 1120 1 NPT (Zinc Aluminum only)
    • Consumes 460 SCFM @80psig
    • Applies 23 lbs of force @12″ from target
    • 30″ wide pattern @48″ from target

They all come, standard, with a 1ft extension. If additional reach is desired, they can also be fitted with 3ft or 6ft rigid pipe extensions. They all have a soft, ergonomic grip, ensuring comfort during extended periods of use.

An optional Gate Valve allows for “on the fly” control of air flow & force. A simple turn of the collar adjusts the flow for a range of variable performance, as dictated by the needs of the application, much like the handheld control offered by our VariBlast Precision and Compact Safety Air Guns.

The optional Gate Valve allows the operator to precisely control the flow – and force – generated by the TurboBlast (left), similar to the adjustability offered by the VariBlast Precision (center) and Compact (right) Safety Air Guns.

The handle itself is one of the most innovative features:

  • Rugged cast aluminum construction, with an over-molded soft, yet rugged elastomer grip is physically durable, and offers superior resistance to UV rays and chemical corrosion.
  • Low profile trigger button for instant & precise control of the air flow. It’s spring operated for “Dead Man Valve” style protection, if dropped or let go of.
  • 1 NPT air inlet for easy & quick connection to a standard industrial air hose.

They are all compliant with OSHA Standard 1910.242(b) with regard to use of compressed air for cleaning purposes, and…they’re on the shelf, right now! We’re pretty excited about this newest addition to our product line. If you’d like to find out more, give me a call.

Minimizing Hazards using the CDC’s Hierarchy of Controls

Published on by EricKuhnash@EXAIR.comLeave a comment
CDc Hierarchy of Controls

The management and effective control to reducing or eliminating workplace hazards can be frustrating. Controlling the exposure(s) to occupational hazards is the fundamental method of protecting employees. The CDC published a useful guide called “Hierarchy of Controls” detailing 5 types of control methods as a means to implement effective control solutions.

The idea behind this hierarchy is that the control methods at the top of graphic are potentially more effective and protective than those at the bottom. Following this hierarchy normally leads to the implementation of inherently safer systems, where the risk of illness or injury has been substantially reduced.

Elimination and substitution, while most effective at reducing workplace hazards, also tend to be the most difficult to implement in an existing process. If the process is still in a development stage, elimination and substitution of hazards may be inexpensive and simple to implement. For an existing process, major changes in equipment and procedures may be required to eliminate a hazard.

With 23 lbs of hard hitting force, this 1-1/4 NPT Super Air Nozzle is perfect for the most extreme blow off and cleaning jobs.

EXAIR can help your company follow the Hierarchy of Controls, to eliminate or reduce the hazards of compressed air usage. Many EXAIR products, including Super Air Knives and Air Amplifiers are simple to use for the substitution level of the hierarchy. The simplest substitution may be any of the EXAIR Air Nozzles and Jets, which have been designed to meet OSHA standards. All are safe to be supplied with higher pressure compressed air and meet OSHA standards 29 CFR 1910.242(b) and 29 CFR-1910.95(a).

Of course, when designing new systems, keep these products in mind and begin to design safer and more efficient compressed air demand elements of your machines and processes.

If you have questions or want to talk to an EXAIR Application Engineer please contact us to discuss how our products will be beneficial to your work environment safety.

Fundamental Modes of Heat Transfer

Published on by Brian FarnoLeave a comment

Generally I like to write about cool stuff. Whether it is a new product like our TurboBlast Safety Air Gun, an application that really helped cool down a process for a customer, or even something cool I have done like a GORUCK event or training. Well, today is not one of those days, today we are going to talk about the opposite of cool … HEAT and more importantly the methods it is transferred.

1 – Energy Transfer – Heat

The process of how heat is generated all starts with a conversion of energy. Whether it is friction, or converting energy to light, or even converting energy to a different voltage through something like a transformer. No matter how it is generated, heat will begin to transfer. On the molecular level, atoms are storing the energy which will cause electrons to enter into an excited state and rapidly switch between shells. When the electron returns back to a lower shell (closer to the nucleus) energy is released; the energy released is then absorbed by atoms at a lower energy state and will continue until the thermal energy is equal between the two objects. Heat has four fundamental modes of transferring energy from surface to surface and they are as follows:

Conduction
Conduction can also be referred to as diffusion and is the transfer of energy between two objects that have made physical contact. When the two objects come into contact with each other thermal energy will flow from the object with the higher temp to the object with the lower temp. A good example of this is placing ice in a glass of water. The temperature is much lower than the room temperature therefore the thermal energy will flow from the water to the ice.

Radiation
Radiation is the transfer of thermal energy through empty space and does require a material between the two objects. Going back to the how thermal energy is released from atoms; when the electron returns to a lower energy shell the energy is released in the form of light ranging from infrared light to UV light. Energy in the form of light can then be absorbed by an object in the form of heat. Everyone experiences radiation transfer every day when you walk outside; the light from the sun’s radiation is what keeps this planet habitable.

Convection
Convection is the transfer of thermal energy between an object and a fluid in motion. The faster the fluid moves the faster heat is transferred. This relies on the specific heat property of a molecule in order to determine the rate at which heat will be transferred. The low the specific heat of a molecule the faster and more volume of the fluid will need to move in order to get full affect of convection. Convection is used in modern ovens in order to get a more even heat through out the food while cooking.

Advection
Advection is the physical transport of a fluid from point A to point B, which includes all internal thermal energy stored inside. Advection can be seen as one of the simpler ways of heat transfer.

No matter how the heat is transferred to an object, if it needs to be cooled there is a good chance that one of our Application Engineers has approached a similar issue and can help. To discuss, contact us and we will walk through the best method to eliminate the heat you need to.
