Sound Power… When I hear that term all I can think of is the classic commercial Maxell®Sound made in 1983. I was only a year old when that commercial graced the presence of everyone’s TV. … More
EXAIR offers the model 9104 Digital Sound Level Meter. It is an easy to use instrument for measuring and monitoring the sound level pressures in and around equipment and other manufacturing processes.
Sound meters convert the movement of a thin membrane due to the pressure waves of sound into an electric signal that is processed and turned into a readable output, typically in dBA. The dBA scale is the weighted scale that most closely matches the human ear in terms of the sounds and frequencies that can be detected.
Noise induced hearing loss can be a significant problem for many workers in manufacturing and mining. To protect workers in the workplace from suffering hearing loss OSHA has set limits to the time of exposure based on the sound level. The information in the OSHA Standard 29 CFR – 1910.95(a) is summarized below.
The EXAIR Digital Sound Level Meter is an accurate and responsive instrument that measures the decibel level of the sound and displays the result on the large optionally back-lit LCD display. There is an “F/S” option to provide measurement in either ‘slow’ or ‘fast’ modes for stable or quickly varying noises. The ‘Max Hold’ function will capture and hold the maximum sound level, and update if a louder sound occurs.
Certification of accuracy and calibration traceable to NIST (National Institute of Standards and Technology) is included.
If you have questions about the Digital Sound Level Meter, or would like to talk about any of the quiet EXAIR Intelligent Compressed Air® Products, feel free to contact EXAIR and myself or one of our Application Engineers can help you determine the best solution.

EXAIR manufactures three different sizes of Back Blow Air Nozzles to clean inside tubing, pipes, hoses, and channels. The 360o rear airflow pattern can “wipe” the entire internal surface clean from coolant, chips, and debris. They are constructed of 316SS, making these nozzles robust and durable.
Our smallest Back Blow Nozzle is the Model 1004SS. It has a M4 X 0.5 male thread and can clean diameters ranging from ¼” (6.3mm) to 1” (25.4mm). Model 1006SS has a ¼” NPT air connection for cleaning inner diameters ranging from 7/8” (22mm) up to 4” (102mm). Our largest Back Blow Air Nozzle is the model 1008SS. It has a 1” NPT connection, and it can be used inside diameters ranging from 2” (51mm) to 16” (406mm).
Now, what can make these unique types of air nozzles even more useful? Attaching them to an EXAIR Safety Air Gun. In this blog, I will go through each of our Back Blow Safety Air Guns that EXAIR can offer from stock.
The unique feature that sets the VariBlast apart from other small air guns is the force variability. The valve is designed to control the opening to allow for a variable force with the same nozzle. The VariBlast is made from a durable cast aluminum construction for tough industrial use. It has a rugged ergonomic grip with a user-friendly trigger. The compressed air inlets are located in two different positions to select the best fit for your application.
With the model 1004SS Back Blow nozzle, the VariBlast Compact Back Blow Safety Air Gun is a small but powerful tool that can clean inside smaller pipes, tubes, and hoses. They come standard with extension tubes and a Chip Shield. The extension tubes range from 6” (152mm) to 36” (914mm) to extend deep inside cavities and openings. The Chip Shield is made from a durable polycarbonate material that will protect your operators during use.
The next air gun in this series is the Soft Grip Safety Air Gun. With an ergonomic soft handle and full-grip trigger, the Soft Grip Safety Air Gun can be used for hours without fatigue. EXAIR offers two types of Back Blow Nozzles with the Soft Grip; model 1004SS and model 1006SS.
As a “bigger cousin” to the VariBlast above, the Soft Grip Back Blow Safety Air Gun with the model 1004SS has extensions ranging from 6” (152mm) to 36” (914mm) as well as a Chip Shield. The Soft Grip with the model 1006SS Back Blow Nozzle has extensions that range from 6” (152mm) to 72” (1,829mm) in length with a Chip Shield. Both of these types of Soft Grip Back Blow Safety Air Guns are great products in allowing you to clean inside a greater variety of diameters and lengths.
For rough industrial environments, EXAIR offers the Heavy Duty Safety Air Guns. They come with a composite rubber grip and a wide curved trigger. It has a 3/8” NPT inlet for increased compressed air flow for those “tough” cleanings.
The Heavy Duty Back Blow Safety Air Gun comes standard with the model 1006SS Back Blow Nozzle, an extension pipe, and a Chip Shield. The extensions lengths can range from 6” (152mm) to 72” (1,829mm). If you need a tough air gun for rugged areas to clean inside pipes and tubes, the Heavy Duty Back Blow Safety Air Gun could be the best candidate for your application.
As our largest model, the Super Blast Back Blow Safety Air Gun has the strongest blowing force. They can clean large areas inside pipes, channels, and tubes ranging from 2” (51mm) to 16” (406mm) in diameter. It has a soft foam grip for easy handling and a spring-loaded manual valve that will turn off if dropped. The model 1008SS Back Blow Nozzle is mounted to an extension that is either 1 foot (0.3m), 3 feet (0.9m), or 6 feet (1.8m) in length. With a 1” NPT inlet, the Super Blast Back Blow Safety Air Gun will generate a strong blast of air for cleaning and removing troublesome material.

During a recent visit with our distributor in Lima, Peru I had the pleasure of visiting a beverage manufacturing facility to discuss EXAIR’s Cabinet Coolers. They have several panels throughout the facility with A/C units installed. A lack of adherence to scheduled maintenance was causing the filters to clog and restrict the cooling power of the A/C unit. Due to staffing issues, their maintenance department was very thin and regular maintenance items were getting missed.
When the filters would clog, the panels would overheat and stop production. Their solution was to open the panel up and blow fans on them, forcing even more dust into the enclosure. In their search for an alternative solution, they came across EXAIR’s Cabinet Cooler Systems and reached out to our distributor. The A/C unit that was installed on the panel had a capacity of 800W (2,728 Btu/hr). EXAIR offers a 2,800 Btu/hr system from stock that matched up perfectly for them.
They installed a Model 4340-24VDC Nema 12 Cabinet Cooler System with 24VDC thermostat control and removed the A/C system. With no moving parts and no refrigerants, there’s absolutely no maintenance required. Just set it and forget it! The Cabinet Cooler has kept the electronics inside at 95°F, preventing any potential for heat related shut downs. Since all Cabinet Coolers must be installed onto a sealed enclosure, there is no need for filters on the enclosure to prevent dirty ambient air from entering. They’re now working to replace each of the A/C units in the facility with an EXAIR Cabinet Cooler.
EXAIR manufactures Cabinet Coolers for any industrial environment. Cabinet Coolers maintain Nema 4, Nema 4X, and Nema 12 integrity on the enclosure and are also UL Listed and CE Compliant. For applications that may be in a classified area, the Hazardous Location Cabinet Cooler has been approved by UL for use in Class 1 Div 1 – Groups A, B, C, and D; Class II Div 1 – Groups E, F, and G; and in Class III areas. Cooling capacities as high as 5,600 Btu/hr can be achieved with one of our Dual Cabinet Cooler Systems.
Stop wasting precious time maintaining you’re A/C systems, or dealing with heat related shutdowns and get a Cabinet Cooler on order today. Fill out the sizing guide online, and one of our Application Engineers will be in touch to provide you with the most suitable model for your application. Act fast, the current Cabinet Cooler promotion expires at the end of August!
As compressed air technology advanced through the 20th Century, its uses multiplied. Pneumatic cylinders became common for rolling and forming presses. The convenience and portability of powerful pneumatic hand held tools spread in assembly and manufacturing facilities. Along the way, operators also found that an open-ended compressed air line could be used for quick and easy blow off in a number of applications. There were, however, some pretty risky safety issues associated with this.
In December of 1970, the Occupational Safety & Health Act became the law of the land, and in 1971, the Occupational Safety & Health Administration (OSHA) was created. Among the many hazards in workplaces they targeted was compressed air use for cleaning. The primary concerns were:
- An open ended blow off could inadvertently be dead ended onto a person’s body, and if the pressure were high enough, it could break the skin and cause a deadly condition called an air embolism. So they limited the outlet pressure to 30psi.
- Blowing something off with air can (and usually does) result in airborne particulate traveling at a high velocity that can imbed in your skin or in your eye. So they mandated the use of proper chip guarding, protective clothing, and eye protection.
This is where the history of the safety air gun begins. Through the 1970’s & 1980’s, engineers rolled out product after product conforming with these new safety standards, sometimes looking for economy, sometimes efficiency…and occasionally, both.
It’s not hard to make a blow off nozzle that complies with OSHA’s dead end pressure requirement; you just need to provide a path for the air to escape in case the nozzle end is blocked. Cross drilled nozzles (shown at right) are simple, cheap, and OSHA compliant, but they’re also loud & inefficient.
EXAIR’s Super Air Nozzles not only protect against injury from dead ended high pressure air, their engineered design also makes them quiet, and efficient. They are commonly installed on the Soft Grip Safety Air Gun. Along with our Chip Shields (shown at right) and your personal protective equipment, you get OSHA compliance, AND lower air consumption & noise levels.
With the Soft Grip Safety Air Gun, you also get a diverse range of options to suit the specific needs of numerous applications:
- Our Model 1210 Soft Grip Safety Air Gun is fitted with our Model 1100 Super Air Nozzle, and is ideal for most typical industrial & commercial blow off tasks. If your needs call for it, though, it also comes with nozzles as small as our Atto Super Air Nozzle (2.5 SCFM; 2.0oz of force) or as large as our Model 1106 High Power Super Air Nozzle (60 SCFM; 3.3 lbs of force.)
- We can provide most Soft Grip Safety Air Guns with Rigid Extensions or Stay Set Hoses, for additional reach and/or aiming of the air flow.
- The Soft Grip Super Air Scraper uses a scraping blade in conjunction with our 2″ Flat Super Air Nozzle to remove stubborn debris like caulk, paint, stickers, gaskets, etc., from flat surfaces.
- Cleaning out the inside diameters of tube, pipe, channel, blind holes, etc., has never been easier than the Soft Grip Back Blow Safety Air Guns. You can get it with the 1004SS (1/4″ to 1″ diameters; 6″ to 36″ extensions) or the 1006SS (7/8″ to 4″ diameters; 6″ to 72″ extensions) Back Blow Nozzles.
If you’re looking for a hand held blow off device, your choices are many. If you’re looking for a quiet, efficient, safe, and versatile one, your choice is easy: the EXAIR Soft Grip Safety Air Gun. Call me and we’ll figure out which one you need.
It is estimated that typically plants can waste up to 30 percent of their generated compressed air and that cost is substantial. Considering the average cost to generate compressed air here in the Midwest is .25 cents per 1,000 Standard Cubic Feet, that translates into .075 cents for every .25 cents spent! Compounded with the fact that energy costs have doubled in the last five years, it couldn’t be a better time to make your air compressor system more efficient.
The following steps will help you save air and in turn save money.
- Measure the air consumption to find sources that use a lot of compressed air.
Knowing where you stand with your compressed air demand is important to be able to quantify the savings once you begin to implement a compressed air optimization program. Placing a value upon your compressed air consumption will also allow you to place a value on its costs and the savings you will reap once you start to reduce your consumption. (EXAIR’s Digital Flow Meter)
- Find and fix the leaks in your compressed air system.
Not fixing your compressed air system leaks can cause your system pressure to fluctuate and affect your equipment negatively. It may cause you to run a larger compressor than necessary for your compressed air needs and raise your total costs. Or it could cause your cycle and run times to increase which leads to increased maintenance to the entire system. (EXAIR’s Ultrasonic Leak Detector)
- Upgrade your blow off, cooling and drying operations using engineered compressed air products.
Your ordinary nozzle with a through hole and a cross drilled hole can be an easy choice based upon price, but if you do not consider the operating cost you do not really know how much it is costing you. An Engineered Air Nozzle will pay for itself and lower operating costs quickly. Engineered Air Nozzles are the future of compressed air efficiency and are made to replace ordinary nozzles, homemade nozzles and open line blow offs. Engineered Nozzles reduce air consumption and noise levels; ordinary nozzles cannot compete. Engineered Nozzles maintain safety features and can qualify for an energy savings rebate from a local utility; ordinary nozzles fall short. Open blow off or homemade blow off applications typically violate OSHA safety standards; Engineered Nozzles do not. (EXAIR’s Air Nozzles)
- Turn off the compressed air when it is not in use.
Automated solutions add solenoid valves and run them from your machine controls. If the machine is off, or the conveyor has stopped – close the solenoid valve and save the air. And blow off applications can benefit from any space in between parts by turning the air off during the gaps with the aid of a sensor and solenoid. (EXAIR’s automated Electronic Flow Control)
- Use intermediate storage of compressed air near the point of use.
Also known as secondary receivers, intermediate air storage is especially effective when a system has shifting demands or large volume use in a specific area. Intermediate storage is the buffer between a large demand event and the output of your compressor. The buffer created by intermediate storage (secondary receiver) prevents pressure fluctuations which may impact other end use operations and affect your end product quality. (EXAIR’s Receiver Tanks)
- Control the air pressure at the point of use to minimize air consumption.
This is a very simple and easy process, all it requires is a pressure regulator. Installing a pressure regulator at all of your point of use applications will allow you to lower the pressure of these applications to the lowest pressure possible for success. Lowering the pressure of the application also lowers the air consumption. And it naturally follows that lower air consumption equals energy savings. (EXAIR’s Pressure Regulators)
By increasing your awareness of the health of your air compressor system and implementing a PM program you can significantly reduce your costs from wasted energy and avoid costly down time from an out of service air compressor.
EXAIR offers several types of Safety Air Guns. Today, we will showcase the Heavy Duty Safety Air Gun. There are hundreds of combinations that can be configured using the Heavy Duty Safety Air Gun, extensions, chip shield, and our engineered air nozzles.
The gun has a number of benefits starting with the metal 3/8″ NPT inlet which permits air flows high enough to operate our model 1106 – 1/2″ Super Air Nozzle. With the 1106 Super Air Nozzle on the gun it will provide 3.3 lbs of force to provide ample cleaning, clearing, or cooling air for the tough industrial jobs.
Secondly, the gun offers an over molded grip that is ergonomic and rugged to handle the industrial environments that maintains its grip even when doused in coolants.
Third, the gun offers a cast 4 finger blade style trigger that permits ergonomic easy trigger pull that can be easily used throughout a work shift. In the event the trigger becomes damaged it can also be easily replaced with stock parts direct from EXAIR.
Fourth, we easily offer any of the Heavy Duty Safety Air Gun combinations with extensions up to 72″ in length and with or without the Chip Shield option.
Lastly, as mentioned in first point, the gun and extensions can be combined with any of the EXAIR Super Air Nozzles up to 1/2″ NPT inlet. Whether you need a small precision puff of air from the Atto Super Air Nozzle, the forcefull blast of the 1106 1/2″ Large Super Air Nozzle, or anywhere in between, there is an engineered nozzle for it and we can couple them with the Heavy Duty Safety Air Gun.
