New EXAIR Product Alert: Introducing the TurboBlast Safety Air Gun

 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 Turbo Blast 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 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.

Siphon Fed Air Atomizing Spray Nozzles

 

Siphon fed nozzles are a great alternative for spraying where no liquid pressure is available. EXAIR has 3 sizes from 1/8 NPT, 1/4 NPT and 1/2 NPT nozzles along with “No-Drip” nozzles in the same sizes. Siphon fed nozzles require no liquid pressure and can be used with gravity fed liquids or lift liquids from a siphon height as much as 36′ (91 cm). Siphon fed nozzles work best with thinner liquids up to 200 centipoise.

EXAIR Air Atomizing Nozzles are manufactured from 303 stainless steel for durability and corrosion resistance. The siphon fed nozzles can be easily implemented where a tank can be installed and lower the cost of the installation by not requiring a liquid pump, just point of use compressed air.

No Drip Siphon Fed Round Pattern Atomizing Nozzle

In addition to the sizes and no drip option the siphon fed nozzle comes in two spray patters. The round pattern offers more liquid pass through and can be used in cleaning, rinsing, cooling and coating applications.

2″ Super Air Amplifier Exhausts Welding Fumes

 EXAIR’s Super Air Amplifiers utilize a patented shim design to maintain critical positioning of component parts. This allows a precise amount of compressed air to be released at exact intervals toward the center of the Super Air Amplifier. This creates a constant, high velocity outlet flow across the entire cross-sectional area. Free, ambient air is entrained through the unit, resulting in high amplification ratios. The balanced outlet airflow minimizes wind shear to produce sound levels far lower than other similar air movers.

While most applications utilize the outlet flow of the Super Air Amplifier to blow off or cool a part or material, the ability of the Super Air Amplifier to entrain large amounts of ambient air can also be utilized to convey light materials or to draw in dust, smoke, or fumes from the surrounding environment.

Recently our principal worked with a customer on an application to install the Model 120022 Super Air Amplifier in welding booths. They did have a current fume extraction system in place, but due to the distance between the vent hoods and the operation some of the fumes were still not being captured. The suggestion was to install a 2” Model 120022 at each booth near the origin of the welding fumes. As the exhaust side of the Super Air Amplifiers come in sizes of ¾”, 1-1/4”, 2”, 4”, and 8” the exhaust flow can be ducted with standard size hose. The placed a 2” ID hose onto the exhaust of the Super Air Amplifier which allowed the fumes to be captured into the intake of the amplifier and be carried towards the vent hood.

This eliminated a safety issue for the operators and was much less expensive than redesigning the entire welding booths and current extraction system. With no moving parts to wear out, the Super Air Amplifier requires absolutely zero maintenance when supplied with clean, dry compressed air. After installing onto each of their welding booths, operators were pleased with the performance and we were able to eliminate the safety hazard for this facility.

Coanda effect

 What is Coanda effect?
The Coanda effect is the tendency of a fluid jet to stay attached to a convex surface. It is named after Romanian inventor Henri Coandă, who described it as "the tendency of a jet of fluid emerging from an orifice to follow an adjacent flat or curved surface and to entrain fluid from the surroundings so that a region of lower pressure develops.

Compressed air flows through an inlet (1) into the plenum chamber of the Super Air Knife. The flow is directed to a precise, slotted orifi ce. As the primary airflow exits the thin slotted nozzle (2), it follows a flat surface that directs the airflow in a perfectly straight line. This creates a uniform sheet of air across the entire length of the Super Air Knife. Velocity loss is minimized and force is maximized as the room air (3) is entrained into the primary airstream at a ratio of 40:1. The result is a well defined sheet of laminar airflow with hard-hitting force and minimal wind shear.

Henri-Marie Coanda (1885-1972) discovered the Coanda Effect in1930. He observed that a stream of air (fluid) emerging from a nozzle tends to follow a nearby curved surface, if the curvature of the surface or angle the surface makes with the stream is not too sharp. For example, if a stream of fluid is flowing along a solid surface which is curved slightly from the stream, the fluid will tend to follow the surface.
A number EXAIR products are designed to utilize the Coanda Effect and aid their performance. In some products, the Coanda Effect aids to create an amplification area where additional ambient air is drawn into the total airflow to increase total volume of air upon a target. This creates a more efficient and effective product. Also, since not as much compressed air is required, the noise levels decrease for products like EXAIR’s air knives, air nozzles, air jets and air amplifiers. EXAIR has been successful with positive impact for compressed air energy savings and noise reductions helping us meet or exceed OSHA Standard.

Engineered Air Nozzles and Jets – There is a Difference.

 EXAIR’s Engineered Air Nozzles and Air Jets provide a superior solution to minimize compressed air usage and reduce noise levels for compressed air blow-off operations.

Air Nozzles and Jets – when compared to commonly used open copper tubes, open pipes, and commercially available air nozzles the compressed air savings can be as high as 80%. With less compressed air, sound levels are greatly reduced.  A 10 dBA noise level reduction is typical.  All EXAIR Air Nozzles and Jets meet OSHA guidelines for dead end pressure and sound level exposure requirements.

EXAIR Nozzles are designed and manufactured to take advantage of the Coanda (wall attachment of a high velocity fluid) effect which can amplify the airflow up to 25 times. The compressed air exits through the small holes on the nozzle which entrains the surrounding air. The effect from this is a high volume, high velocity blast using less compressed air.  EXAIR manufactures many sizes and styles of air nozzles from the smallest, but quite powerful Atto Super Air Nozzles to our largest 1-1/4 NPT Super Air Nozzle.  We also offer Flat Super Air Nozzles, and the Back Blow style nozzle for cleaning out tubes, pipes, channels or holes from 1/4″ to 16″ in diameter.

All of our Air Nozzles are engineered to meet or exceed OSHA Standard 1910.24(b) for 30 PSIG dead end pressure, they cannot be dead-ended as there is always a route for the air to escape so the outlet pressure will never reach 30 PSIG. In addition, our products are going to meet the OSHA Standard CFR 29 – 1910.95(a) for allowable noise exposure levels.

EXAIR Air Jets also utilize the Coanda effect to produce air motion in their surroundings.  A small amount of compressed air (1) is throttled through an internal ring nozzle above sonic velocity.  A vacuum is produced, pulling in large volumes of surrounding, or ‘free’ air, through an around the jet (2).  The exit flow is the combination of the two air sources (3).

 Exair manufactures Air Jets in two types, High Velocity, and Adjustable with materials of construction of brass and Type 303 Stainless Steel.  The High Velocity Air Jet uses a changeable shim to set the gap, controlling the force and flow of the air.  The Adjustable does not use a shim, and has a micrometer gap indicator and locking ring to allow for varying force and flow performance.

If you would like to discuss blow off, noise levels, dead end pressure or any of Exair intelligent compressed air usage solutions, Please contact us.

Custom Vortex Tubes by EXAIR

 EXAIR’s Vortex Tubes are a low-cost, reliable, and maintenance-free solution to a variety of industrial spot cooling problems. With just an ordinary supply of compressed air, the Vortex Tube produces two streams of air: one hot and one cold. This is achieved without any moving parts or refrigerants!!

The Vortex Tube is capable of achieving a temperature drop/rise from your compressed air supply ranging from -50°F to +260°F (-46°C to +127°C). Flow rates range from 1-150 SCFM (28-4,248 SLPM) and refrigeration of up to 10,200 Btu/hr. With all Vortex Tubes constructed of stainless steel, they’re resistant to corrosion and oxidation ensuring you years of reliable, maintenance-free operation.

In addition to providing a range of different Vortex Tubes available to ship same-day from stock, EXAIR also has a few options available for cases where a stock Vortex Tube may not be the right solution. The standard Vortex Tube is suitable for use in environments with ambient temperatures up to 125°F (52°C) due to the plastic generator and Buna o-rings. For more extreme environments and ambient temperatures up to 200°F (93°C), we install a brass generator and replace the Buna o-rings with Viton seals.

All standard Vortex Tubes are adjustable. A small valve is located at the hot air exhaust end of the tube. Using a flat-tipped screwdriver, you can adjust the amount of air that is permitted to exhaust from the hot end. As more air is allowed to escape, the temperature at the cold end of the tube drops even further. The volume of air at the cold end as the temperature drops will also decrease. The percentage of air exhausting from the cold end relative to the total air consumption is referred to as the cold fraction percentage. Lower cold fractions will produce lower temperatures, but there won’t be as much volume. Finding the proper setting for your Vortex Tube can take some adjusting.

As we all know, if there’s a knob to turn, button to press, or adjustment that can be made an operator is inevitably going to tinker with it. Day shift will blame the night shift, night shift blames the day shift, and it can present a problem when the Vortex Tube has been specifically tested and set to achieve the desired cold fraction. If you know the cold fraction you need, but would prefer to prevent it from being able to be adjusted, EXAIR can install a precisely drilled hot plug to set the cold fraction percentage to your specifications and eliminate any potential for it to be changed.

If you’d still prefer to keep the adjustability, but don’t have the capabilities to measure and set it yourself, we can also set any Vortex Tube to the desired cold fraction with the adjustable valve and send it to you ready to be installed. We’ll provide you with a special model number so you can rest assured that any time you need another it’ll come set to your specification.

If you have a unique application and would like more information on getting a special Vortex Tube, contact an Application Engineer today.
