EXAIR Safety Air Gun Promotion is Here!

Published on by Al WooffittLeave a comment

Through the months of August and September, EXAIR is running our Safety Air Gun Promotion. End-users throughout the United States and Canada will receive a free Model 1126, 1″ Flat Super Air Nozzle when they purchase a Safety Air Gun direct through us. This includes our VariBlast Precision, VariBlast Compact, Soft Grip, Heavy Duty, and TurboBlast Safety Air Guns.

For in depth information about our line of Safety Air Guns and this promotion, head on over to EXAIR.com to learn more. But for a brief summary of our Safety Air Guns, stick around in this blog!

All of our Safety Air Guns are durable and comfortable to use. Every model is designed to use an engineered Air Nozzle that will entrain large volumes of air, enabling them to be quiet and efficient. This allows them to be OSHA compliant to OSHA standard 1910.242 (b); the airflow cannot be blocked or dead ended.

Our VariBlast Precision Safety Air Gun is extremely lightweight and the most comfortable to operate during long periods of extended use. It features a variable trigger valve which produces varying force levels depending on how much the trigger is activated. The small diameter nozzle and extension will fit into tight spaces while providing a strong blowing force.

The VariBlast Compact Safety Air Gun is a uniquely powerful gun which produces variable force depending on trigger activation. This cast aluminum gun is equipped with any of our 1/8 NPT engineered air nozzles. The VariBlast Compact Safety Air Gun is small, comfortable and powerful while remaining light and ergonomic. It has two inlets for flexible air supply options and a large loop at the top for hanging when not in use.

The Soft Grip Safety Air Gun has a durable cast aluminum body suitable for rugged industrial use. The large trigger makes for easy operation and a convenient hook at the top allows the gun to be easily stored. Chip Shields for worker safety and extensions for hard to reach areas are available, up to 72” long.

The Heavy Duty style of safety air gun is powerful with a durable aluminum cast body and ergonomic composite rubber grip, best suited for rugged industrial environments. Hours of fatigue-free operation are possible. The 3/8 NPT inlet also allows for greater compressed air flow, resulting in higher force and flow than other air guns.

Features & benefits of the new TurboBlast Safety Air Gun

Finally, our TurboBlast Safety Air Gun is designed for extended use without fatigue during the most demanding applications, which require a huge amount of force to solve. These air guns produce up to 23 pounds of force onto a target! The rugged cast aluminum handle is covered with a soft, durable elastomer grip. The low profile trigger button will disengage if released. 3′ and 6′ extensions are available.

If you would like to take advantage of this promotion, or if you would like to discuss any other point-of-use compressed air application, give us a call!

Mag Bases and Stay Set Hoses

Published on by Al WooffittLeave a comment

When considering your blowoff solution, the angle at which you direct the airflow is very important. This is often found through testing and trying. Once you have found the sweet spot for your engineered, compressed air nozzle, you want to be sure that it won’t move. This is where our Stay Set Hoses and Mag Bases come in.

Flexible and durable, EXAIR Stay Set Hoses come in lengths from 6″ to 36″.


Our Stay Set Hoses have a memory function, so they won’t creep or droop until you physically move them. They are perfect for directing the air flow in a particular direction, or at a specific target. Just be sure you are adjusting them properly to keep them operating for years to come. The Stay Set Hoses come in lengths from 6″ (15cm) to 36″ (91cm), and they have threaded connections with either 1/4″ NPT male on both ends or with a 1/8″ NPT female X 1/4″ NPT male thread. The hoses are made from reinforced synthetic rubber and have a maximum pressure rating of 250 PSIG, and can withstand temperatures of up to 158°F (70°C).

Our Mag Bases can quickly be mounted to any solid steel surface. With 100lb (45.5kg) of pulling force, they will keep your blowoff device firmly in place, whether mounted horizontally, or vertically. They can also be easily moved when a different position is needed. With three different options; a 1-outlet, 2-outlet and a 1-outlet swivel. The 1/4 turn shut off valve allows for easy control to ensure you’re not wasting compressed air when it’s not needed.

If you have a blowoff application that you would like to discuss, don’t hesitate to give us a call. We’d love to discuss the best solution for you!

Daniel Bernoulli and His Effect on EXAIR Products

Published on by Al WooffittLeave a comment

Daniel Bernoulli was born on February 8, 1700, in Groningen in the Netherlands. He is the son of Mathematician Johann Bernoulli, who was an early developer of Calculus. Daniel took an interest in mathematics when he was just 7 years old. Although his father tried to dissuade him from focusing on mathematics due to the limited financial gain, Johann did tutor his son in calculus and theories of kinetic energy.

Daniel continued to show promise, attending Basel University at the age of 13, where he studied logic and philosophy. By the time he was 15 years old, he had completed his bachelor’s degree, and earned his master’s degree a year later. At the age of 23, he moved to Venice, Italy to learn medicine, but he couldn’t get away from mathematics, becoming a professor of a university in Venice a year later.

In 1738, Bernoulli published the book Hydrodynamica, where he first explained what we know as Bernoulli’s Principle. This is of particular interest to us at EXAIR, as many of our products operate off of this principle. It states that an increase in the speed of a fluid occurs simultaneously with a decrease in pressure. This is derived from the conservation of energy, where an increase in kinetic energy (speed) requires a corresponding reduction in potential energy (pressure).

When compressed air exits the precise slotted nozzle of our Super Air Knife, this induces a low pressure area, which speeds up and draws in ambient air. This air entrainment (at a ratio of 40:1) is what makes our Super Air Knives so efficient. This same effect can be witnessed with our Super Air Amplifiers, Super Air Nozzles, Super Air Wipes, as well as many other products.

The high speed of the air exiting the (left to right) the Air Wipe, Super Air Knife, Super Air Nozzle, and Air Amplifier creates a low pressure (just like Daniel Bernoulli said) that causes entrainment of an enormous amount of air from the surrounding environment.  This maximizes flow while minimizing consumption of your compressed air.

If you would like to discuss your application, and how the Bernoulli Principle may be beneficial, feel free to give us a call!

Compressed Air Safety Do’s and Don’t’s

Published on by Al WooffittLeave a comment

DO take compressed air safety seriously. We are all familiar with the importance of safety. Almost every company has some form of annual safety training. One of the common themes of these kinds of training is that it is not just some people’s responsibility, but that it is everyone’s responsibility. Here at EXAIR we take safety seriously. All of our products are engineered with safety in mind – we even have a line of products with ‘safety’ in the name – Safety Air Guns. This is very important, as working with compressed air can present some health risks if not used properly.

OSHA, the Occupational Safety and Health Administration, is an organization here in the United States that enforces governmental directives for safe and healthy working environments. They can also enforce these directives with heavy fines for violations.  With compressed air, the two most common violations are air guns and blowoff devices are described in 29CFR 1910.242(b) for dead-end pressure/chip shielding and 29CFR 1910.95(a) for maximum allowable noise exposure.

The first regulation – 29CFR 1910.242(b) – references the use of hand-held tools. DON’T use a blowoff device at more than 30psig if the compressed air can be dead-ended. If the compressed air has no other path to escape, it can penetrate the skin, causing an air embolism. A common and simple solution is to cross-drill a hole to allow an alternate path. This could create other safety issues, as we will discuss later. EXAIR’s nozzles are designed with fins which allow the air to escape and not be blocked by your skin.  So, you can safely use the EXAIR Super Air Nozzles above 30psig.

The second regulation – 29CFR 1910.95(a) – references the maximum allowable sounds level an individual should be exposed to. DON’T allow an operator to be exposed to excessive sound levels for too long. This is where the cross-drilled nozzle falls short. Although safe from dead-end pressure, the sound produced by the turbulent airflow is very loud. The engineered design of EXAIR’s nozzles entrain the surrounding air into a laminar flow, which is much quieter. Our Model 1210 Safety Air Gun (which uses our Model 1100 Nozzle) only has a sounds level of 74dBA, which is comfortably under the noise exposure limit for 8 hours.

If you want to take compressed air safety seriously, then DO use EXAIR’s line of safe, quiet and efficient Safety Air Guns and Air Nozzles. If you would like to discuss this, or any of your other compressed air application needs, then give me a call!
