I recently had the pleasure of talking with a caller from a consulting firm that specializes in improved ergonomics. They work with clients on everything from preventing carpal tunnel syndrome through the use of things like gel-filled mouse pads for office personnel, to preventing injuries in the workplace due to repetitive strain, heavy lifting, and other physically demanding tasks. They called about an operation where workers used buckets to move 150 pounds of dense pellets from a large container into a smaller vessel for weight load testing. After the test, they move the pellets back into the container, where they stay until the next test is to be run. Then they do it again.
This, of course, was a great fit for a 2″ Heavy Duty Line Vac and a 10ft length of Conveyance Hose. They simply move the suction & discharge hoses from, and to, the storage container & test vessel. Risk of injury is greatly reduced, as the whole Line Vac conveyance system is less than half the weight of one bucket of the material.
This is just the latest success story in the long history of EXAIR Air Operated Conveyors. They’re on the shelf in a range of sizes and materials of construction to meet most any need. If you don’t see what you’re looking for, though, call me and we can discuss your needs.

For over 34 years, EXAIR has been the industry leader in providing Intelligent Compressed Air Products to the industrial marketplace. While much of our focus is to ensure our products are engineered to provide optimal performance, we are also dedicated to manufacturing products that meet a wide range of standards and directives to promote safety in relation to plant personnel.
For instance, all of our compressed air operated products meet or exceed OSHA Standards 29 CFR 1910.242(b), requiring that the outlet pressure of an open pipe, nozzle, air gun, etc., when used for cleaning purposes, must remain below 30 PSI when dead-ended against the skin, as well as Standard 29 CFR 1910.95(a) as a way to protect workers from job related injuries related to dangerous sound levels of 90 dBA and higher.
Many of our products are also CE Compliant, meeting the mandatory requirements for products intended to be sold in the European Economic Area or “EEA”. For example our Electronic Flow Control and Electronic Temperature Control (ETC) meet the EU (European Union) Low Voltage Directive 2006/95/EC.
EXAIR electrically powered devices, like our Static Eliminators and Digital Flowmeters for example, comply with the “Restriction of Hazardous Substances” or RoHS Directive 2011/65/EU, including the amendment outlined in the European Commission decision L 214/65.
We are also committed to providing material that supports the conflict mineral free rule to help aid in the relief of illegal trade of exotic materials, like tungsten, gold, tin and tantalum in the DRC region. Using the CMRT 4.20 template, we document our supply resources to ensure we provide conflict free products, as outlined in Section 1502 of the Dodd-Frank Wall Street Reform and Consumer Protection Act.
Lastly, the European Union introduced the REACH program – Registration, Evaluation, Authorization and Restriction of Chemicals, as a method to register chemical substances being imported into the EU to protect people and the environment, per Regulation (EC) No 1907/2006 Title I, Article 3. Also noted in the program, Title II, Article 7, they state that any product with a substance intended to be released under normal operating conditions, must be registered for quantities totaling more than 1 metric ton per year. Since EXAIR products do not intentionally release or contain any such substances, registration to meet the program is not required.
If you have any questions about any of these Standards or Directives or about which EXAIR products comply, please feel free to contact an application engineer for assistance. We’d be happy to help!
Just getting back in the swing of things after being on vacation last week. My family, along with my mother, went on a 7 day Eastern Caribbean cruise which included 3 days at sea and 3 days at different ports. Our port stops included the Bahamas, San Juan Puerto Rico and the island of St. Maarten. My wife and I have cruised several times and have already visited these islands, but with this cruise being our son’s and my mother’s first, we thought we would try to experience some different things.
Our last port was St. Maarten, where “we” (my wife and mother) planned our day of shopping and having an authentic lunch at a local restaurant. With the shopping portion of the day complete, we started asking locals for a good place to have lunch. We met a local who ran his own taxi company and recommended we have lunch at Maho Beach but it was going to be a 20 minute taxi ride. When we arrived, for some reason the area seemed somewhat familiar and then it hit me…. I’ve seen this place on TV! Their airport sits right on the edge of the island and arriving and departing planes basically fly right over your head while sitting at the restaurant/bar or swimming at the beach.
People line up along the road and fence line and wait for the next plane (the restaurant/bar has arrival and departure screens and will yell out when a large commercial jetliner is approaching), making it a very crowded area. Due to the potential jet blast coming from the engines there are safety signs posted that people ignore. I did ask one of the restaurant/bar managers if safety is such a concern, then why do they allow people to line up and he said “all they can do is warn people, if they want to subject themselves to injury, then that’s on them”. I don’t want to see anyone getting hurt, but I must admit, it is a little humorous to see people get blown all over the beach. Needless to say, we stood a good distance away.
In all seriousness, safety should be a primary concern. Is your plant currently practicing safety when dealing with compressed air? Open pipes, tubes or drilled pipe can consume large amounts of compressed air, and exceed the pressure and noise level thresholds outlined by OSHA. And we are all aware that personnel don’t always abide by the safety rules – much like ignoring a safety sign.
At EXAIR, our customer’s safety is of utmost importance. All of our intelligent compressed air products meet or exceed the OSHA standard 1910.242(b) for safety. This means that you can still operate the devices at 80 psig while not having to worry about an operator injuring themselves with the compressed air. This is not just for one product line, but ALL of the compressed air products that we manufacture.
By implementing the EXAIR engineered solutions into your facility you can effectively lower the noise level cause by unsafe compressed air blow offs and possibly eliminate the need for hearing protection all together. In my experience any time an operator doesn’t need to wear hearing protection or you can make their surrounding environment a little quieter, they tend to be a little happier which, always leads to better production. Again, many resources back this up, loud noise can also create physical and psychological stress.
These are just two of the standards that EXAIR will never take a vacation on. Every product that EXAIR designs must be safe for operator operations, whether that be through pressure output or through the noise level it creates.
Last week, I received an email from a satisfied customer, after he had already purchased our product. Come to find out this customer had not spoken to an application engineer during the planning stage to make their purchase. With our excellent resources listed at EXAIR.com, the customer was able to fulfill his application without even speaking to us. After his initial email of thanks, he also shared with me some details of his application that I want to share with you today.
The customer works as a machinist at a large aircraft part manufacturer. The parts require a very tight tolerance. A sample of each part needed to be gauged and measured in an automatic thread gauging machine or a coordinate-measuring machine (CMM). Their machining process required a water based flood coolant, so each part would be coated in water based coolant and chips, which needed to be remove before gauging. Before visiting EXAIR’s site, the company used a variety of homemade and commercial blow offs, as safety air gun tips. Here is a photo of (20) of the (25) nozzles the customer was using.
As you can see, the nozzles vary in design purpose, flow and safety. Most of the nozzles feature a cross drilled hole or a secondary escape path, but not all of the nozzles do. Any nozzle without a secondary relief port violates OSHA standard CFR 1910.242(b), so replacing some of the nozzles increased the safety in the plant. Secondly, these nozzles are wasteful in their use of compressed air because some were designed as liquid nozzles and have large exit holes. A hole that is 1/8″ in diameter at the nozzle outlet can consume up to 21.4 SCFM of compressed air at 80 PSIG. For comparison, the model 1103 Mini Super Air Nozzle with a 1/8″ NPT inlet will flow 10 SCFM at 80 PSIG, which would be a 53% compressed air savings. In 24 running hours, the 1103 nozzle will save 16,416 Standard Cubic Feet, which the plant spent $4.10 for a standard industrial compressor to produce (The standard for compressed air cost is $0.25 per 1,000 SCF). Replacing just one 1/8″ drilled hole with 1103 Mini Super Air Nozzle saves the aircraft company $1,026 over 250 working days running 24 hours a day.
Neither of these were the real reason that the customer emailed to thank us though. He was actually an office employee just entering the work force. Starting in June until after the company finally acquiesced to his request to buy a better, quieter nozzle near the end of July, he had left work needing an aspirin to relieve the headache he acquired due to the noise from these other nozzles. The nozzles the machining center had been using would create noise levels between 88-100 dBA at 80 PSIG of inlet pressure. For reference OSHA mandates that employees are required to wear hearing protection, if they are exposed to noise levels over 90 dBA over an 8 hour work day. The employees doing the machining wear hearing protection, but the employees in the office were still exposed and affected by the noise level. This is just one anecdotal example, but everyday more and more research shows that noise exposure has a negative effect on our health and productivity in the workplace. If you are interested in more information here are some links to a number of studies/research – please read this, here or this.
Anyway, that’s enough of my soapbox. The company purchased 25 of EXAIR’s 1103 Mini Super Air Nozzles and utilizing the same guns they were currently using saw between a 10-15 dBA decrease in noise levels near the work stations. Here is a photo of one of their setups with the model 1103 installed on one of their current air guns.
We know that every time they squeeze that air gun trigger they will be using less compressed air than before, and we know they are now in compliance with OSHA. But the best benefit for EXAIR is we know that the engineer took the time to email us to thank us for taking away his headache everyday. That’s enough for me.
