Noise In The Workplace

Published on by Russ BowmanLeave a comment

The Center for Disease Control (CDC) estimates that 22 million workers are exposed to potentially dangerous levels of noise at work every year. That’s “only” about 15% of the total number of people who are employed in the United States, but if you’re one of them, you should absolutely know the risks, and how to protect yourself. Obviously, high noise levels can cause hearing loss, but do you know what else it causes?

  • Cardiovascular disease. Constant noise exposure causes stress, and stress triggers the release of hormones that increase your blood pressure, which can lead to ischemic heart disease, strokes, and arrhythmia.
  • Sleep disruption. Studies show chronic noise exposure during the day can cause difficulty falling asleep, shortened sleep cycles, and frequent wake-ups during the night. All this leads to chronic fatigue and a host of long-term health issues.
  • Immune system suppression. While the exact nature of the relationship is unclear, recent studies have indicated that noise can cause changes in our immune systems.
  • Cognitive impairment: Continued noise exposure causes memory impairment, attention deficits, and reduced concentration.
  • Mental health issues. Not only does continued noise exposure release hormones like cortisol & adrenaline (causing the chronic stress that’ll literally break your heart; see above), it directly influences anxiety, depression, and irritability.
Don’t let this happen to you.

So, how do we protect ourselves? If you said “ear plugs,” you’re not wrong…but did you know that hearing protection in the form of personnel protective equipment (PPE) is considered the LEAST effective method of mitigating noise exposure? The National Institute for Occupational Safety and Health (NIOSH, a sister agency of the Occupational Safety and Health Administration, or OSHA) developed a hierarchy of controls…a “good, better, best” framework, if you will, of methods to address workplace hazards:

Even though hearing protection (the PPE in this case) is least effective, the intent of the hierarchy graphic is not to dismiss it, but to categorize it as a last resort. If all else fails (or, more often, comes up short,) ear plugs are your – and your hearing’s – best friend.

If the source of the noise cannot be eliminated (and let’s face it, an awful lot of industrial processes are necessarily loud), the next best thing to do is to substitute a quieter method or device. That’s where EXAIR comes in: the design of our engineered Air Knives, Air Nozzles, and Air Amplifiers exploits certain principles of fluidics to mitigate the noise levels associated with the rapid depressurization of compressed air when it’s blown for cleaning, drying, cooling, etc. The key to this is entrainment:

EXAIR Intelligent Compressed Air Products such as (left to right) the Air Wipe, Super Air Knife, Super Air Nozzle, and Air Amplifier are engineered to entrain enormous amounts of air from the surrounding environment.

While this entrainment makes EXAIR products EXTREMELY efficient (the compressed air consumption ends up being a fraction of the total developed flow), it also creates a low velocity boundary layer around the primary high velocity & forceful airflow. This layer attenuates the sound level of that high velocity flow.

Compressed air use can be loud, wasteful, and dangerous, but it doesn’t have to be. If you’re looking for a quiet, safe, and efficient solution for your use of compressed air, give me a call.

Air Compressors: Rotary Type

Published on by John BallLeave a comment

What is an air compressor? In simple terms, it is a machine that increases fluid pressure.  It works by either changing the volume of air, positive displacement, or by changing the velocity of the air dynamics.  Many industries use air compressors to operate pneumatic equipment.  In this blog, I wish to cover the Rotary Compressor.

The Rotary Screw Compressor is a very common type of air compressor. This compressor uses dual rotors with meshing lobes that trap air while rotating. The rotation continues to push air toward a discharge port while decreasing the space the air takes up, thus increasing pressure. The rotary type of air compressor has five different sub-categories, reference image above.  This style of air compressor has some clear advantages and disadvantages:

Advantages:

  • Quiet Operations
  • Durability and Low Maintenance
  • High Efficiency
  • Continuous duty Cycle

Disadvantages:

  • High initial cost
  • Specialized maintenance

No matter the type of air compressor you use, they are very costly to operate.  To help you use them efficiently and safely, EXAIR offers a range of products that can clean, cool, blow, conserve, and convey.  This would include our Super Air Knives, Super Air Nozzles, Safety Air Guns, Cabinet Coolers, and much more.  If you want to save energy, increase safety, and cut costs no matter what size air compressor you have, you can contact an Application Engineer at EXAIR.  We will be happy to help.

Overview: Heavy Duty Dry Vac

Published on by jasonkirbyLeave a comment
EXAIR Reversible Drum Vac (left) and Heavy Duty Dry Vac (right) Two Industrial Vacuums – wet AND dry – for less than the purchase AND operating cost of a dual Venturi vacuum.

EXAIR produces a variety of industrial pneumatic drum vacuums designed to effectively manage spills and debris in diverse environments. These vacuums are characterized by their safety, quiet operation, and the absence of moving parts or electric motors, which enhances their longevity and reliability. With a proven track record of durability, the Industrial Housekeeping Products line includes systems tailored for both dry and wet materials, as well as a versatile option that accommodates both types. In this blog, I will focus on our Heavy Duty Dry Vac System.

A prevalent problem associated with dry materials is the premature failure of electrical motors due to dust accumulation. In many electrically powered vacuums, this dust can lead to the deterioration of motor bearings, often resulting in a loud screeching sound. In contrast, EXAIR’s Heavy Duty Dry Vac System features no moving parts, eliminating wear and maintenance needs, and operates solely on compressed air. It includes a static-resistant hose to prevent electric shocks when handling dry, dusty materials. Constructed from hardened alloy steel, the Heavy Duty Dry Vac offers exceptional abrasion resistance and generates a powerful vacuum of -60” H2O (-15 kPa) at 80 PSIG (5.5 bar), making it suitable for use with sandblasting materials, garnet, and steel shot. Additionally, its efficient and durable bag filter effectively contains dust within the drum while allowing air to escape.

We offer three drum sizes—30-gallon, 55-gallon, and 110-gallon—tailored to your specific application and material volume needs. Each drum is equipped with a Heavy Duty Vacuum that operates on just 68 SCFM (1,924 SLPM) of compressed air at 80 psig (5.5 bar). To suit various requirements, we provide different packages for each drum. The standard package includes essential components such as the drum lid with necessary hardware, a side latching lever lock, a shutoff valve, a filter bag, 10 feet of static-resistant vacuum hose, a hose hanger, 20 feet of compressed air hose, a pressure gauge, and an aluminum chip wand. For those seeking more features, the Deluxe package adds a drum dolly, heavy-duty aluminum tools, and a tool holder. Finally, the Premium package encompasses all items in the Deluxe package along with a steel drum.

If you have questions about our Heavy Duty Dry Vac, or anything regarding EXAIR and our products, please do not hesitate to reach out.
