Mufflers to Protect Manufacturing Workers Hearing

Mufflers

Many manufacturing plants have a strong focus on safety for their workers.  One major safety concern that is overlooked is noise.   OSHA, Occupational Safety and Health Administration, has a directive that defines the noise exposure over time; 29CFR 1910.95(a).   For an eight-hour day, the maximum noise level is 90 dBA.  Hearing loss is irreversible, but it can be preventable.  The CDC, Center for Disease Control, and NIOSH, National Institute for Occupational Safety and Health, report that “approximately 18% of all manufacturing workers have hearing difficulty”1

EXAIR manufactures engineered products to reduce noise levels in the work environment.  We offer Super Air Nozzles and Safety Air Guns for blow-off applications and pneumatic mufflers for discharge exhaust.  In this blog, I will cover the different types of EXAIR Mufflers that we offer.   

  1. Reclassifying Mufflers are designed to have two functions. They can cut noise levels by 35 dB and remove oil mist from the exhaust air.  Cylinders and valves that exhaust pressurized air may have oil in the line to keep the seals from sticking.  When exhausted, it can create a fine mist which is dangerous for operators.  The Reclassifying Mufflers can reduce the loud noise as well as collect any contamination from the exhaust air.
  2. Sintered Bronze Mufflers are simple in design, cost effective, and easy to install. They have a minimal back pressure to not restrict operations of the pneumatic device.  They come in sizes from #10-32 thread to 1-1/2” NPT.  For a quick and simple way to reduce noise, the Sintered Bronze Mufflers are in stock for fast delivery.
  3. Straight-Through Mufflers offer a way to reduce noise levels without worrying about clogging. They have an aluminum shell lined with sound absorbing foam, and they can reduce the noise level by 20 dB.  EXAIR offers them with ports of ¼” NPT, 3/8” NPT, and ¾” NPT.  One side has a female thread while the opposite side will have a male thread.  This can allow you to connect other items like hose kits to reduce noise.
  4. Heavy Duty Mufflers are used within aggressive environments.  They have an outer aluminum shell with an internal stainless-steel screen.  They protect components like valves and cylinders from contamination entering into the part.  And, the Heavy Duty Muffler can keep contaminant like rust from being ejected at high speed into the work area. They have a typical noise reduction of 14 dB.

Here is a test for you.  If you go and stand in your plant, you can probably hear loud noises coming from your compressed air system.  EXAIR has an engineered product to solve most of them.  On the Hierarchy of Controls for NIOSH, Personal Protection Equipment, PPE, is the least effective.  A better control would be to isolate your operators from the hazard with an engineered product.  EXAIR can offer that solution for many of your blow-offs and pneumatic discharges to reduce noise levels.  This would include; and not limited to; Super Air Nozzles, Safety Air Guns, Super Air Knives, and Mufflers.  If you wish to discuss further the safety improvements that EXAIR can provide, you can contact an Application Engineer.  We will be happy to help.

Air Nozzles and Air Jets: An Overview

One of the simplest solutions to lower your air consumption and noise level when it comes to compressed air is to switch your open tubes or pipes and liquid nozzles which are being used for air applications to an engineered compressed air nozzle. EXAIR’s Engineered Air Nozzles and Jets provide a simple solution for a wide variety blow off and compressed air applications and can solve a multitude of process problems efficiently. These applications can include simple blow offs, cooling, part ejection, and much more.

Super Air Nozzles:
Super Air Nozzles are one of the more versatile of all of EXAIR’s Engineered Air Nozzles. They come in many different sizes from a tiny size of M4 threads and 13 millimeters long to the largest with  1-1/4 NPT threads which has a 2″ hex and is almost 5″ long. These are usually used for standard blow off applications that replace open pipes to reduce your air consumption and noise. The force values vary from 2 ounces to 23 pounds of force. 

Another variation of the Super Air Nozzles is the Flat Super Air Nozzles; these nozzles create a small flat curtain of air at a high force to provide a wider blow off area for smaller NPT sized nozzles. The 1” and 2” Flat Super Air Nozzle also have replaceable shims that allow you to adjust the force coming out of the nozzle by increasing the amount of air that is used.

Back Blow Air Nozzles:
Back Blow Air Nozzles are designed in a way that blows that makes it easy to blow out the inside of pipes. The Back Blow Air Nozzles have holes around the outside diameter pointed back that creates a cone of air around the air inlet port. This makes it easy to dislodge clogs in pipes that you don’t want going back into the machine and for blowing out liquid and debris from the inside. They are also commonly used with EXAIR’s Chip Shield as to prevent any particles from flying back and hitting the user. Back Blow Air Nozzles come in three sizes: M4, ¼”, and 1” and can be used on inside diameters ranging from ¼” to 16”.

Super Air Nozzle Clusters:
Super Air Nozzle Clusters use a number of the ¼” Super Air Nozzles to create one nozzle that has a wider cone and larger force. Clusters are usually used in wide area blow off but can also be used for part cooling and part reject as they do supply a wider area of force. Super Air Nozzle Clusters are sized by the number of nozzles in the cluster; the three sizes that we offer are 4-nozzle cluster (3/8” NPT inlet), 7-nozzle cluster (1/2” NPT inlet), and the 12-nozzle cluster (1” NPT inlet).

Air Jets:
Air Jets amplify the total volume of air into a high velocity stream of air. This makes it very useful for blowing off/drying applications and cooling applications due to the higher volume of air flowing through the unit. Air Jets come in two variations which are the High Velocity Air Jet and the Adjustable Air Jets. The High Velocity Air Jet uses a 0.015” shim that allows the air to escape the unit at a high velocity laminar flow to entrain the surrounding ambient air; this can be adjusted down using the shim kit which includes a 0.006” and 0.009” shims. The Adjustable Air Jet allows the user to easily adjust the air gap using the micrometer gap indicator.

50 Years of Earth Day – Happy Earth Day!

Today marks the 50th anniversary of Earth Day and it will be observed in over 190 countries. For EXAIR, this year marks our 37th year helping compressed air users save compressed air energy and electrical resources. And the 37th year for improving our own efficiencies and processes in order to reduce waste. Because your volunteer opportunities may not be available this year, Earthday.org has gone digital for 2020 and is providing ways to participate via your computer.

EXAIR remains committed to a minimal footprint and continues to focus on manufacturing our products with little impact and doing our part to help protect our planet. We are proud to manufacture efficient products, implement processes and programs throughout our facility to help use our resources wisely and recycle everything we possibly can.

We manufacture and sell Intelligent Compressed Air Products that are specifically designed to reduce the use of compressed air throughout facilities.  On top of that, when you purchase an EXAIR product it will arrive in fully recyclable packaging and, in most cases, is made from a material that will be recyclable should it reach a point it is no longer useful.

Over the past years we continually look for improvement opportunities within our systems and processes. Recently we have…

  • Over the past year, EXAIR recycled 1300 yards of paper and cardboard.
  • Recycled 100% of our cardboard and mixed paper products. Of the waste we place into our trash dumpsters – 80% is recycled and 20% is sent to the landfill.
  • Recycled 100% of the metal scrap from our machining processes. Improvements in these processes has reduced scrap rates, which equates to 5.5 tons of recycled metal.
  • Used our very own Chip Trapper Systems in our manufacturing areas to extend the water-soluble coolant life from 6 weeks per changeover to 6 months per changeover. Keeping our coolant clean allows us to minimize the total amount of wastewater we recycle each year.
  • Further reduced our wastewater for reclamation by another 25% compared to last year.
  • Minimized our own compressed air use by 1 million cubic feet per year
  • Made improvements to the efficiency of our computers and computer servers which require fewer Kilowatt hours (KWH) per day

Another waste reducing factor that has proven to work out well for EXAIR is asking every customer if they accept digital invoices rather than requiring them to be printed and mailed.  We have been able to eliminate over 91% of all printed and mailed invoices. This helps to reduce our resources used as well as the amount of materials that are possibly turned into solid wastes at customer facilities. This also prevents the gas and vehicles necessary to deliver all of these invoices by mail.

Adding to the efforts above, we continue to maintain RoHS compliance on all electronic products, as well as actively track our supply chains to ensure no Conflict Minerals are being sourced and used in our products.

If you have any questions on how we can help your facility reduce their volume of compressed air or why we continue to reduce our wastes and increase our recycling efforts, contact us.

Happy Earth Day from EXAIR!
