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.

Safety should always be a serious concern within industrial environments. Walk through any production facility and you should see all kinds of steps taken to give a safe workplace to the operators, contractors, and other team members. Whether this is through a sign showing PPE required to enter an area, an emergency exit sign, a safe walkway, or machine guards. Safety has become a standard that should never be lowered and there is good reason for that.
EXAIR designs all of our products to be safe and they meet or exceed OSHA standards that are directed toward compressed air safety. The first is to ensure that an operator or maintenance worker will not be injured through air impinging their skin should they come into contact with an EXAIR product. This OSHA standard is 29 CFR1910.242(b) claiming that all point of use compressed air products must be regulated to have less than 30 psig of dead end pressure. This directive is critical for worker safety and the way many blowoffs skirt by is to cross drill holes in the end of the blowoff.
Cross drilled holes may satisfy the dead end pressure standard but it does not address OSHA’s next important compressed air standard about noise exposure, OSHA standard 29CFR1910.95(a). The allowable noise level standard combined with 30 psig dead end pressure will render many home made or retail nozzles near useless because few, if any, meet both standards. Again, EXAIR has engineered and designed our Super Air Nozzles to permit 80 psig inlet pressure and still meet or exceed both of these OSHA standards so that the work can still be done by the operators while remaining safe and retaining their hearing.
For a better explanation and demonstration of how our nozzles meet these standards please see the video below.
While I use nozzles and cross drilled pipes as examples within this blog these safety features are designed into every product that EXAIR offers. This is due to the fact that OSHA, NIOSH, and the CDC do not delineate between a blow gun, blow off within a machine, or even a Cabinet Cooler System. If the device is powered by compressed air then the two key OSHA standard are in effect due to the inherit dangers of compressed air.
I encourage you now to walk through your facility and try to listen or spot compressed air points of use within your facility. Then, I ask you to call, chat, e-mail, or tweet an Application Engineer here at EXAIR and let us help you determine the most efficient and safest product to get the work done.
Use of compressed air, or “the fourth utility” as it’s called, is widespread in many industries. How you use it in your business is important, for a couple of key considerations:
Compressed air isn’t free. Heck, it isn’t even cheap. According to a Tip Sheet on the U.S. Department of Energy’s website, some companies estimate the cost of generation at $0.18 – $0.30 per 1,000 cubic feet of air. A typical industrial air compressor will make 4-5 Standard Cubic Feet per Minute per horsepower. Let’s be generous and assume that our 100HP compressor puts out 500 SCFM and is fully loaded 85% of the time over two shifts per day, five days a week:
500 SCFM X $0.18/1,000 SCF X 60 min/hr X 16 hr/day X 5 days/week X 52 weeks/year =
$22,464.00 estimated annual compressed air cost
If you want to go jot down some numbers from your compressor’s nameplate and your last electric bill, you can accurately calculate your actual cost. Here’s the formula:
Taking our same 100HP compressor (105 bhp required,) fully loaded 85% of the time, and assuming the motor’s good (95% efficient):
(105 bhp X 0.746 X 4,160 hours X $0.08/kWh X 0.85 X 1.0)÷ 0.95 =
$23,324.20 actual annual compressed air cost
So, our estimate was within 4% of our actual…but the point is, $22,000 to $23,000 is a significant amount of money, which deserves to be spent as wisely as possible, and that means using your compressed air efficiently. Engineered solutions like EXAIR Intelligent Compressed Air Products can be a major part of this – look through our Case Studies; implementing our products have saved companies as much as 60% on their compressed air costs.
Health & Safety
Injuries and illnesses can be big expenses for business as well. Inefficient use of compressed air can be downright unsafe. Open ended blow offs present serious hazards, if dead-ended…the pressurized (energized) flow can break the skin and cause a deadly air embolism. Even some air nozzles that can’t be dead ended (see examples of cross-drilled nozzles on right) cause a different safety hazard, hearing loss due to noise exposure. This is another case where EXAIR can help. Not only are our Intelligent Compressed Air Products fully OSHA compliant in regard to dead end pressure, their efficient design also makes them much quieter than other devices.
Efficient use of compressed air can make a big difference in the workplace – not only to your financial bottom line, but to everyone’s safety, health, and livelihood. If you’d like to find out more about how EXAIR can help, give me a call.

EXAIR prides itself in offering products with high-performance and peak efficiency. All EXAIR products are manufactured to meet the strict requirements of a variety of different standards, ensuring that you receive a reliable, high quality product that WILL perform to the specifications we publish.
Safety is a top priority for most companies, EXAIR’s line of Intelligent Compressed Air Products meet or exceed the strict safety standards set forth by both OSHA and the European Union. EXAIR products comply with OSHA 29 CFR 1910.242(b), the standard implemented to ensure safe operation of compressed air blowoff devices, and the EU General Product Safety Directive (2001/95/EC).
Additionally, they comply with the noise limitation requirements set forth under 29 CFR 1910.95(a) and the EU Machinery Directive (2006/42/EC). From the Optimization product line, EXAIR’s Electronic Flow Control and the Electronic Temperature Control meet the low voltage standards of EU Low Voltage Directive (2006/95/EC). A CE label is placed on all products that comply with applicable directives.
UL, or Underwriters Laboratories, is a third-party safety and consulting organization that certifies products after thorough testing and evaluation. EXAIR’s Cabinet Coolers are UL Listed to US and Canadian safety standards. Static Eliminators are also UL Component Recognized. Within our line of Cabinet Coolers is the Hazardous Location Cabinet Cooler, bearing the Classified UL mark for use in classified areas.
In the assembly of electrical products there can be hazardous materials used during production. The Restriction of Hazardous Substances, also known as RoHS or (2002/95/EC), restricts the use of materials such as: lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (CrVI), polybrominated biphenyls (PBB), polybrominated diphenyl ethers (PBDE), and four different phthalates. The electrical portions of EXAIR’s Static Eliminators, Electronic Flow Control, Electronic Temperature Control, Digital Flowmeter, solenoid valves, and thermostats all comply with the amendment outlined in the European Commission decision L 214/65.
In addition to RoHS, EXAIR is also committed to providing products that are conflict mineral free. In support of Section 1502 of the Dodd-Frank Wall Street Reform and Consumer protection Act, EXAIR complies with the conflict minerals rule to curb illicit trade of tin, tantalum, tungsten and gold in the DRC region. Using the CMRT 4.20 template, we’re able to document our supply chain to ensure our materials are not being sourced from places that could finance conflict in the DRC and surrounding countries.
Finally, per Regulation (EC) No 1907/2006 Title I, Article 3, paragraph 3, the European Union enacted legislation requiring substances and chemicals imported into the EU to be registered to ensure a high level of protection for human health and the environment. Per Title II, Article 7, paragraph 1, articles must be registered when a substance is intended to be released during normal conditions of use that would exceed 1 metric ton per producer per year. Since EXAIR products do not contain substances that are intentionally released, registration is not required.
If you’re looking to maintain compliance in your industry, EXAIR products have you covered. If you have any questions about these standards of compliance feel free to reach out to us. Our team of Application Engineers have years of experience in industry are waiting to take your call.
If you have ever walked into a manufacturing facility and heard the hiss or even worse the banshee scream of compressed air being exhausted to ambient, whether it be from a cylinder discharge, a timed drain going off, or a bypass valve being activated, they all could be hushed with a muffler. A muffler for compressed air comes in several shapes and sizes. EXAIR offers four separate types from stock to help attenuate the noise disruption within your facility.
The OSHA standard for allowable noise exposure is 29 CFR-1910.95(a) and outlines the number of hours per day any individual can be exposed to a particular noise level. These noise levels are expressed in decibels (dbA).
The first type I would like to showcase are the Reclassifying Mufflers. These are ideal for cylinder exhausts or valves which commonly contain an oil mist within the air stream which can easily contaminate the surrounding area. The patented design of the removable element separates oil from the exhausted air so virtually no atomized oil is released into the environment. They also attenuate the exhaust noise level up to 35 decibels. The filter element helps the exhaust to meet the OSHA Standard 29 CFR 1910.1000, a worker’s cumulative exposure to oil mist must not exceed 5 mg/m³ by volume in any eight hour shift of a forty hour work week.
The chart below helps to properly size the Reclassifying Muffler for a pneumatic cylinder. One key to proper installation of these mufflers is they must be installed vertically in order to properly trap and drain the oil.
The next type of muffler to discuss are the Sintered Bronze Mufflers that are offered in ten different sizes. These are an excellent low cost solution which easily install into new or existing ports. Each size is designed to provide minimal back pressure and restriction for the individual port size. The quick pick chart below helps to easily select the correct size for attenuating the exhaust of a pneumatic cylinder. One key difference between these and the Reclassifying Mufflers is, these do not have to be oriented vertically as they do not collect the oil out of the exhaust air.
If the process air needs to be directed or plumbed away from the operator then the Straight Through Mufflers are the ideal selection as they offer an NPT threaded inlet and exhaust. They are available in three standard NPT sizes from stock. These mufflers can be installed in any orientation and work well with our Vortex Tubes to help pass the cold air through while lowering the operating sound level of the tube. The average noise reduction of the Straight-Through Mufflers is 20 dB. This can easily reduce the noise level of an operation to below the OSHA standard requiring hearing protection for operators in the area.
The final option for mufflers from EXAIR are the Heavy Duty Mufflers. These are available in two sizes from stock and are constructed of corrosion-resistant aluminum with a stainless steel internal screen. These can be installed in any orientation and are ideal for protecting exhaust ports from contaminants that may clog or damage the device they are attached to. The typical noise reduction from installation is 14 dB with these mufflers.

To summarize, EXAIR offers a multitude of options when it comes to lowering sound levels in operation areas that are caused by exhausted compressed air. Each of the mufflers discussed above are shipped same day from stock to meet your immediate need. If you are unsure of which muffler to use for your application, feel free to contact an Application Engineer.
Throughout my years here at EXAIR as well as my years in the metal cutting industry, one of the most common quick fixes I see in production environments for compressed air blowoffs in a process is an open copper pipe that is contorted into a position, pinched at the end, and more often than not kinked from repositioning. I call this a quick fix because it does blow air, more often than not it will get production up and running, but it does not meet or exceed OSHA standards for safety and is an inefficient use of compressed air. [OSHA Standards 29 CFR 1910.242(b) and 29 CFR 1910.95(a)]
The first engineered solution I could offer to prevent any costly OSHA fines and to lower the ambient noise level caused by these blowoffs is to implement an EXAIR Engineered Air Nozzle. We offer a wide variety of nozzles ranging from a 4mm thread up to a 1-1/4″ NPT thread. With this wide range comes a wide variety of forces and flows as well.
Today, I would like to focus on the common sizes of copper blowoffs which are 1/8″ and 1/4″. To simply adapt a nozzle to copper line a compression fitting can be easily sourced, often from EXAIR, and convert the copper tubing in place to an NPT threaded outlet for easy installation of an EXAIR nozzle. More often than not a compression fitting is how the copper tubing is tied into the machine’s compressed air system.
We have a total of 37 engineered air nozzles from stock that will easily fit a compression fitting which goes to a 1/8″ NPT or 1/4″ NPT thread. Several of these are also adjustable through a gap adjustment or a patented shim adjustment to vary the force and flow out of the nozzle from a forceful blast to a gentle breeze in order to me your application needs. What if you want to eliminate the copper line and compressions fittings?
EXAIR offers a replacement option for the ever-common copper tube that is more robust and does not require a tool to be properly repositioned. We currently offer twenty-four different models of our Stay Set Hoses that can be easily connected to any of the nozzles mentioned above. The lengths that are available are 6″ (152mm), 12″ (305mm), 18″ (457mm), 24″ (610mm), 30″ (762mm) and 36″ (914mm).
These lengths are available with two separate connection options. 1/4″ MNPT x 1/4″ MNPT or 1/4″ MNPT x 1/8″ FNPT. The Stay Set Hoses can easily be bent by hand into position for a precise placement of the air pattern from the engineered nozzle attached to it. This permits operators a tool free adjustment for fast and reliable location to keep production up and running. They can also be paired with Magnetic Bases.
EXAIR Magnetic Bases are available in single outlet or dual outlet configurations. Both include a 100 lb. pull magnet that will hold tight to any ferrous metal surface for secure mounting, as well as a quick 1/4 turn miniature valve on each outlet. This permits independent customization of the force our of each output for the dual outlet mag base. Each magnetic base offers a 1/4″ FNPT inlet port and outlet port. We offer these with any of combination of the Stay Set Hoses mentioned above as well as any of the Super Air Nozzles mentioned above.
The Super Air Nozzles, Stay Set Hoses, and Magnetic Bases can be easily combined before they ship to your facility to make a complete blowoff station that is easily installed and adjusted to fit any of the needs your process may have for a point of use blowoff. If you want help determining how much compressed air you would save by replacing the open pipe blowoffs with an engineered solution like a Stay Set Magnetic Base Blowoff System please contact myself or any Application Engineer here at EXAIR.
