The Human Side of Safety: Why EXAIR’s Certifications Are Your True Safety Net

Published on by Neal RakerLeave a comment

On a busy production floor, it’s easy to look at an agency certification—like OSHA, UL, or
CE—as just another piece of administrative paperwork. But at EXAIR, we see them differently. We see them as a promise made to the people who power your business every day.

For your operators, these certifications aren’t just labels; they represent certainty. Here is how our commitment to these standards changes the daily lives of your team.

Preserving the Sound of Life

Constant, high-pitched air noise isn’t just an annoyance; it’s a health hazard. Excessive noise leads to permanent hearing loss, chronic stress, and fatigue that can cause workplace accidents. By engineering our products to meet OSHA 1910.95(a) standards, we ensure your team can communicate clearly and go home without ringing in their ears. It’s about protecting their long-term health, not just hitting a decibel target.

Removing the Risk of “Dead-Ending”

The risk of an air embolism—where high-pressure air enters the bloodstream—is a terrifying reality in industrial environments. Our compliance with OSHA 29 CFR 1910.242(b) means we’ve engineered that danger out of the equation. Our nozzles feature safety relief paths that can never be blocked by a person’s skin while still operating the nozzles at a pressure level that can still deliver forceful blowing results. We believe that a simple cleaning task should never lead to a medical emergency.

Peace of Mind Through Global Compliance

Whether it’s ensuring our electrical products are UL Listed to protect your equipment or maintaining CE and RoHS compliance for our global partners, we handle the technical heavy lifting. This allows you to focus on your production goals, knowing your tools are ethically sourced, environmentally safe, and meet the highest global quality benchmarks.

Success Story Spotlight: Silencing the Shop Floor

One of our favorite examples of these standards in action involves a customer who was struggling with deafening noise levels.

The Human Challenge:
The facility was using open-ended blow-off guns that produced a staggering 104 dBA. For the operators, this meant constant discomfort, heavy ear protection, and high stress. Though the guns were “functional,” the environment they created was unsustainable.

The EXAIR Solution:
The facility replaced their old equipment with 355 EXAIR Soft Grip Safety Air Guns

The Transformation:

  • The Sound of Silence: Noise levels dropped to 82 dB – a perceived reduction of over 150% for the human ear.
  • Full Compliance: The shop floor immediately met OSHA allowable noise exposure standards, creating a vastly more comfortable environment.
  • A Financial Win: Along with the safety boost, the facility saved over $28,500 annually in compressed air costs.

The Outcome:
The operators finally had a workspace where they could focus and stay safe. It’s a perfect example of how choosing the right certified tool doesn’t just improve the bottom line – it improves the work lives of the people who matter most. And that’s what we are all about, solving technical problems with a set of solutions that keep operator safety, health and operational efficiency at the forefront of the process.

Revolutionize Your Internal Pipe Cleaning with EXAIR Back Blow Nozzles

Published on by Al WooffittLeave a comment

In industrial manufacturing, cleaning the inside of pipes, tubes, and blind holes has traditionally been a challenge. Standard forward-blowing nozzles often push debris deeper or create safety hazards by ejecting material out the far end. EXAIR solved this problem with their innovative Back Blow Air Nozzles, designed specifically to “wipe” internal surfaces clean by directing airflow backwards toward the operator.

How They Work

These nozzles utilize the Coanda effect to amplify compressed air, entraining surrounding ambient air to create a high-velocity 360-degree cone of air. Because the air is directed back toward the inlet, it pulls coolant, chips, and debris out of the opening rather than forcing them further in.

See the “Back Blow Magic” in Action

Watch this EXAIR video demonstration to see a Back Blow Nozzle clear debris from a plugged pipe in a single pass.

Common Applications

Manufacturers across various industries use these nozzles to improve efficiency and safety. Typical uses include:

  • Machined Part Cleaning: Removing coolant and metal chips from blind holes or internal threads.
  • Hydraulic Cylinder Repair: Cleaning honed bores ranging from 2″ to 16″ in diameter.
  • Tube & Pipe Manufacturing: Clearing debris from long lengths of pipe where forward blowing is impractical.
  • CNC Machining: Quickly cleaning out spindles between tool changes.
  • Electronics Recycling: Removing residual powder from spent toner cartridges.

Key Product Features

  • Material: Manufactured from durable Type 316 Stainless Steel for superior corrosion and wear resistance.
  • Size Range: Available in three sizes—M4, 1/4 NPT, and 1 NPT—covering internal diameters from 1/4″ to 16″.
  • Safety & Compliance: Meets OSHA standards for noise and dead-end pressure.
  • Configurations: Can be mounted on VariBlast, Soft Grip, or Heavy Duty Safety Air Guns with extensions up to 72″ and optional chip shields for operator protection.

Supporting The Next Generation of Engineers

Published on by Brian FarnoLeave a comment

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.

Understanding OSHA and Compressed Air Safety: A Guide for Modern Facilities

Published on by Al WooffittLeave a comment

Maintaining a safe workplace isn’t just a legal requirement—it’s the backbone of a productive and healthy business. One of the most common yet overlooked hazards in industrial environments is the improper use of compressed air. In this blog, we’ll break down what OSHA is, the specific risks of compressed air, and how EXAIR products can help you stay compliant while improving efficiency.

What is OSHA?

The Occupational Safety and Health Administration (OSHA) is a federal agency within the U.S. Department of Labor, established by the OSH Act of 1970. Its mission is to ensure safe and healthful working conditions by setting and enforcing standards and providing training, outreach, and assistance.

Under OSHA, employers have a fundamental responsibility to provide a workplace free from recognized hazards—a requirement known as the General Duty Clause.

Compressed Air: The Hidden Hazards

Compressed air is a powerful energy source, but it carries significant risks if not managed correctly. OSHA focuses on two primary safety standards regarding its use:

  • Dead-End Pressure (29 CFR 1910.242(b)): Compressed air used for cleaning must be reduced to less than 30 psi (pounds per square inch) if the nozzle is “dead-ended” or blocked. Higher pressures can cause air to enter the bloodstream (air embolism), leading to serious injury or even death.
  • Noise Exposure (29 CFR 1910.95(a)): High-velocity air can be incredibly loud. OSHA sets strict permissible noise exposure limits for workers during an 8-hour shift to prevent permanent hearing loss.
  • Chip Guarding: OSHA also requires “effective chip guarding” and personal protective equipment (PPE) to protect workers from flying debris when using compressed air for cleaning.

How EXAIR Products Ensure Compliance

Many facilities struggle to balance the need for high-force air with these safety regulations. EXAIR specializes in “Intelligent Compressed Air” products designed to meet or exceed OSHA standards without sacrificing performance.

1. Safety Air Guns

EXAIR Safety Air Guns are engineered to be safe even when used with air supplies at 80–120 psi. They feature specialized nozzles that cannot be dead-ended, ensuring the static pressure remains below 30 psi:

Model 1210 Soft Grip Safety Air is fitted with an EXAIR Super Air Nozzle. We can also supply it with a Rigid Extension and Chip Shield (right).

Model 1210 Soft Grip Safety Air Gun with Model 1100T Air Nozzle, operating at just 74 dBA—well below OSHA’s 8-hour limit. Featuring an ergonomic design, this Air Gun can be fitted with zinc-aluminum, stainless steel, or PEEK plastic nozzles.

2. Engineered Air Nozzles

Instead of using open-ended pipes (which are loud, wasteful, and unsafe), EXAIR’s Super Air Nozzles use a small amount of compressed air to entrain large volumes of surrounding air. This creates a quiet, high-velocity laminar flow.

EXAIR Super Air Nozzle entrainment
  • Safety Feature: Fins on the nozzle allow air to escape if the tip is pressed against a surface, preventing dangerous pressure buildup.

3. Chip Shields and Extensions

To meet the “chip guarding” requirement, EXAIR offers polycarbonate chip shields that can be added to any safety air gun (look for the -CS suffix on models like the 1240-CS). Extension pipes are also available to allow cleaning of hard-to-reach areas while keeping the operator at a safe distance.

Final Thoughts

OSHA inspections are often unannounced. By replacing unsafe, loud, and inefficient blow off tools with EXAIR Intelligent Compressed Air products, you not only protect your workers from injury and hearing loss but also avoid costly fines and reduce your facility’s energy consumption.
