Blowoff Made Easy With the Variblast Safety Air Gun

Published on by jasonkirbyLeave a comment

EXAIR’s VariBlast Safety Air Guns provide a significant advancement in handheld blow off technology by effectively addressing the hazardous “all-or-nothing” airflow characteristic of conventional air blow guns. This innovative series combines precise, adjustable force control with top-tier safety standards, ensuring operator protection while significantly reducing costly compressed air consumption. Top that off with the fact that these units are actually repairable, and you have a win all the way around!

In standard industrial environments, inexpensive handheld air guns are often disregarded, despite being a significant source of hidden expenses stemming from high air consumption, potential hearing risks, and serious safety violations. To address these issues, EXAIR has developed the VariBlast series, which offers an efficient and ergonomic solution that easily adjusts to various tasks.

The VariBlast series is distinguished by its innovative variable-flow trigger mechanism. In contrast to inexpensive blow off guns that release a continuous and uncontrolled stream of compressed air, the specialized valve within the VariBlast adapts responsively to the user’s input.

The ergonomic trigger, when squeezed, progressively opens the internal valve, enabling operators to gently displace fine dust particles with a soft airflow or exert up to a full pound of force to completely blow away heavier debris. This precise control mechanism helps to avoid excessive use of compressed air, thereby significantly reducing utility expenses for the facility.

To tackle everything from heavy manufacturing to delicate electronics assembly, EXAIR offers the VariBlast blow gun in two distinct variations:

Meets or Exceeds OSHA Requirements
  • VariBlast Compact Safety Air Guns are constructed from robust cast aluminum, ensuring their resilience in demanding industrial environments. These air guns are equipped with dual 1/4 NPT inlets, making them suitable for connection with overhead tool retractors or counter balancers, and they can be paired with any of EXAIR’s 1/8 NPT Super Air Nozzles for enhanced functionality.
  • The VariBlast Precision Safety Air Guns are specifically designed for meticulous and detailed tasks, featuring a lightweight construction made from high-impact thermoplastic. This model is equipped with EXAIR’s three smallest engineered nozzle profiles, which include the ultra-compact Atto, the mid-range Pico, and the fine-point Nano, allowing for versatile applications in precision work.

Safety is not an afterthought with EXAIR; it is baked right into the engineering. Every VariBlast blow gun model completely bypasses standard factory penalties by natively fulfilling two essential OSHA mandates:

OSHA StandardSafety RequirementHow VariBlast Complies
29 CFR 1910.242(b)Restricts dead-end static pressure greater than 30 PSI if a nozzle is blocked.Engineered Super Air Nozzles maximize air entrainment and cannot be accidentally blocked or dead-ended by an operator’s hand.
29 CFR 1910.95(a)Protects operators against continuous industrial noise exposure over 90 dBA.Advanced nozzle geometry drops operation sound levels between 58 and 82 dBA—well within safe, permissible daily, 8-hour exposure thresholds.

Compressed Air Safety Fundamentals

Published on by jasonkirbyLeave a comment

Safety in the workplace is of paramount importance, and it is widely recognized that annual safety training is a common practice among organizations. A fundamental message from these training sessions is that safety is a collective responsibility, not limited to a select few. At EXAIR, we prioritize safety in all aspects of our operations. Our product line, particularly our Safety Air Guns, exemplifies this commitment, as they are engineered with safety considerations at the forefront. This emphasis on safety is critical, especially given the potential health hazards associated with the improper use of compressed air.

In the United States, the Occupational Safety and Health Administration (OSHA) is responsible for enforcing regulations that promote safe and healthy working conditions. This agency possesses the power to levy significant fines for any infractions. Among the frequent violations related to compressed air are those concerning air guns and blow-off devices, specifically detailed in 29CFR 1910.242(b), which addresses dead-end pressure and chip shielding, as well as 29CFR 1910.95(a), which pertains to permissible noise exposure levels.

The regulation 29CFR 1910.242(b) addresses the use of hand-held tools, particularly emphasizing that blow-off devices must not operate at pressures exceeding 30 PSIG when there is a risk of compressed air becoming dead-ended. In situations where there is no escape route for the air, it poses a serious risk of penetrating the skin and causing an air embolism. A potential remedy is to drill a hole to create an alternative escape route. However, this solution may introduce additional safety hazards, which will be discussed later. EXAIR’s air nozzles are engineered with fins that facilitate safe air escape, thereby preventing skin blockage. Consequently, users can operate the EXAIR Super Air Nozzles at pressures exceeding 30 PSIG with confidence.

The regulation 29CFR 1910.95(a) specifies the permissible sound levels for safe human exposure, emphasizing that extended exposure to elevated noise can result in irreversible hearing loss. However, the cross-drilled nozzle falls short in this regard, as it generates significant noise due to turbulent airflow, despite being suitable for dead-end pressure applications. In contrast, EXAIR’s nozzles are engineered to incorporate ambient air, resulting in a significantly quieter laminar flow. For example, the Model 1210 Safety Air Gun, equipped with the Model 1100 Nozzle, operates at a sound level of only 74dBA, which is comfortably below the noise exposure threshold for an eight-hour work shift.

The Value of Precision

Why EXAIR Delivers More Than “Cheap” Alternatives Ever Can

The Overlooked Opportunity in Compressed Air Efficiency

In the compressed air industry, most efficiency initiatives focus on the production side of the system. Significant resources are invested in improving compressor efficiency, upgrading controls, managing pressure drops, and recovering heat. At the same time, leak detection and repair programs have rightly gained momentum as a powerful way to eliminate waste.

These efforts are essential—and they should absolutely continue.

However, there is a third major opportunity for efficiency that is frequently overlooked:
the products used at the point of use.

In many facilities, compressed air is consumed by open pipes, improvised blow-offs, improperly sized nozzles, or low-cost devices that were never engineered for efficiency. Some compressed air advisors focus exclusively on eliminating compressed air applications entirely. While that approach has its place, it ignores an important reality:

Compressed air is an extremely valuable, flexible, and effective utility when it is used correctly.

The real opportunity is not just to produce compressed air more efficiently or stop leaks—it is to use compressed air more intelligently where it actually does the work.

This is where engineered compressed air products come into play.

Manufacturers like EXAIR demonstrate that compressed air does not have to be inherently wasteful. Through precision engineering, optimized air entrainment, and application‑specific design, EXAIR products dramatically reduce air consumption while improving performance, safety, and reliability.

The result is a smarter compressed air strategy—one that recognizes that efficient point‑of‑use products are just as important as efficient compressors and proactive leak management.

Precision That Pays You Back

When evaluating compressed air products, it’s easy to focus on purchase price alone. But in real-world industrial environments, the actual cost isn’t what you pay upfront, it’s what you pay to operate, maintain, and replace that product over time.

That’s where EXAIR stands apart.

EXAIR products are engineered to deliver measurable energy savings, safer operation, and long-term reliability, helping customers lower operating costs while improving productivity and compliance.

Save Energy. Reduce Operating Costs.

Compressed air is one of the most expensive utilities in any plant. Even small inefficiencies at the point of use can result in thousands of dollars in wasted electricity each year.

What makes EXAIR different:
EXAIR air nozzles and air amplifiers are precision‑engineered to maximize air entrainment while minimizing compressed air consumption. Compared to open pipes or low‑cost alternatives with crude internal geometry, EXAIR products can typically reduce air usage by 30–50%.

What this means for the customer:

  • Lower energy costs
  • Reduced compressor run time and maintenance
  • Fast, measurable ROI—often in months

A nozzle that costs less today may silently waste far more tomorrow.

Built‑In Safety. Built‑In Compliance.

Safety is not optional—and non‑compliant compressed air devices introduce risk for both employees and the organization.

What makes EXAIR different:
EXAIR products are engineered to meet OSHA requirements for noise levels and dead‑end pressure, reducing the risk of injury and eliminating compliance concerns that often accompany low‑cost imports.

What this means for our customers:

  • Lower workplace risk
  • Easier EHS audits
  • Confidence that safety has been designed into the solution—not added later

With EXAIR, safety is part of the product, not a compromise.

Reliability That Protects Uptime

Downtime is expensive. Failures caused by clogging, worn components, or inconsistent manufacturing often show up at the worst possible moment.

What makes EXAIR different:
Many EXAIR products—including Vortex Tubes and Air Knives—are designed with no moving parts. No bearings to fail. No internal mechanisms to wear out. Just consistent, repeatable performance.

What this means for the customer:

  • Maximum uptime
  • Minimal maintenance
  • Long service life, even in harsh environments

Install it once. Depend on it for years.

More Than a Product—An Engineering Partner

Low-cost compressed air products often come with little more than a tracking number. When performance issues arise, the support ends at delivery.

What makes EXAIR different:
Every EXAIR solution is supported by experienced Application Engineers who help ensure the product is properly selected, sized, and applied.

What this means for our customers:

  • Faster implementation
  • Optimized performance
  • Reduced trial‑and‑error costs

You are not just buying a compressed air product, you are gaining our expertise in solving the very problems that plague manufacturing processes.

The EXAIR Value Proposition

When customers choose EXAIR, they gain:

  • Lower energy consumption
  • Improved safety and compliance
  • Proven durability and reliability
  • Expert application support

All of this delivers the lowest total cost of ownership—not just the lowest purchase price.

Before choosing a cheaper alternative, the real question is:

  • What is the cost of wasted compressed air over time?
  • What is the cost of downtime?
  • What is the risk of non‑compliant equipment?

EXAIR is precision engineering that pays for itself.

Supporting The Next Generation of Engineers

A while back, I was lucky enough to spearhead a donation from EXAIR to The University of Cincinnati’s 1819 Innovation Hub Makerspace. For the past several years, we have been sponsoring the UC Combat Robotics club, which uses the Makerspace to build its bots and learn more about the applications of its course of study. This facility is open to all students who attend the university. The course of study does not matter; the desire to learn appropriate usage of equipment and a determination to create are all that is needed.

The space puts every student through training for safety and manufacturing processes, if needed, and then the students can operate on their own. The staff in the space are often students themselves, or they are people with years of industry experience to share with the students utilizing the space. This 12,000 square-foot makerspace and fab lab is home to a variety of equipment that can all be seen on their equipment listing here. You can go in and learn how to use anything from a sewing machine or soldering iron, all the way up to a 4-axis CNC machine. If you just have an idea and desire to learn, the staff will even train you on how to make the idea come to life and do it all safely in a semi-controlled environment.

When we saw the need for safe, efficient use of compressed air in this space, EXAIR stepped in to help. We outfitted every air drop in the facility and every machine with an EXAIR VariBlast Precision Safety Air Gun w/ Chip Shield and Nano Super Air Nozzle. This will help keep all the operators safe by eliminating the risk of exceeding 30 psig dead-end pressure and also reducing the operating noise level to below the OSHA standard of 85 dBA, all the way down to 75 dBA. By keeping the entire facility uniform, they are also able to make purchasing new units easier when they are needed.

We also helped them assemble their new EXAIR Chip Trapper System to help recycle the coolant from their CNC machines and help them extend the life of their cutting fluid by being able to remove all the debris from their sumps, reducing the surface area on which bacteria can grow.

On top of both of these, we helped them to see how easy a Cold Gun is to mount onto the side of virtually any machine in their shop, even the industrial sewing machine, and showed them just how beneficial it can be. There was actually a group of students using one of the stationary belt sanders, and we were able to connect the Cold Gun to the closest air drop, use the magnet to hold it onto the housing of the sander, and position the single-point cold outlet to the contact point to keep the sandpaper and material cooler to prevent loading up of the sandpaper.

These were just a couple of the products we were able to share with them in order to help outfit their space with safe and efficient compressed air products. I’ve condensed the entire event down into a 50-second clip if you would like to watch. I feel like we need some classic Benny Hill music in the background.

I think the best part of this experience for me was the discussion that evolved as we unpacked all the items. We had already had lots of chatter back and forth around what their system is capable of and also what they plan to do with the EXAIR products. Then, as we are unpacking and discussing the capabilities, more applications started to come up. I have a feeling this is just part of what happens in this space. Ideas are born, then brought into fruition, all within these walls.

Special thanks to Benjamin Jones and his team for letting us be part of training the future leaders in the industry.
