EXAIR manufactures three different sizes of Back Blow Air Nozzles to clean inside tubing, pipes, hoses, blind holes, and channels. The 360o rear airflow pattern can “wipe” the entire internal surface clean from coolant, chips,… More
Compressed air can be one of the more expensive utilities to use in a facility, but a compressed air system is full of simple opportunities to increase efficiency and minimize the cost. Much like how you can take multiple steps to save electricity at your house there a few simple steps you can take to save your compressed air. These steps include finding and repairing leaks, compressor maintenance, minimizing pressure at the point of use, and turning the compressed air off when not in use. Implementing these steps and using the right tools to achieve them can lead to significant dollar savings – in fact our website case studies, other blog articles and catalog are filled with example after example of air (and dollar) savings success! And let’s be honest here, who doesn’t like saving money.
First off is finding your leaks. Leaks are one of the major wastes of compressed air in a system that could happen. Leaks in a compressed air system can account for wasting 20-30% of a compressors output. These leaks can commonly be found in pipe joints, devices that use the compressed air, quick connect fittings, and storage tanks. All of this compounds to wasting air much like a leaky faucet wastes water – little by little it grows until it simply needs to be addressed. One of the ways to help find leaks in your system is EXAIR’s affordable Ultrasonic Leak Detector. This leak detector uses ultrasonic waves to detect where costly leaks can be found so that they can be patched or fixed.
Choose efficient end-use products. Engineered air knives, air amplifiers, air nozzles and safety air guns can dramatically outperform (use less air) than commercial air nozzles and in-house solutions such as drilled pipes, open air lines and other creative “fixes”. We have seen some very nice in-house solutions from customers who have put in some significant time and effort, but they all have one thing in common – they use more air than any of EXAIR’s engineered solutions.
Minimizing your pressure can also save you money by limiting the amount of compressed air that is being used. Pressure and volume go hand and hand, the higher the pressure the higher the volume of air and vice versa. By minimizing the pressure that you are using you are also minimizing the amount of air that is being used which means savings. Each CFM used can be associated with a certain price value so the less you use the more you save. You also cut down on the amount of work the compressor has to do and how often the compressor has to cycle. Pressure can be minimized using one of EXAIR’s Pressure Regulators to cut down on the amount of air being used.
Turn off the compressed air when it is not in use. Just like how you wouldn’t leave the faucet running or lights on in a room that is not being used, don’t leave your compressed air running (insert bad dad joke). Constantly using compressed air even when not in use will cause the compressor to cycle more often wasting money. Each CFM has a price to it so don’t waste CFM’s blowing it back into the air and doing nothing. This can simply be done by adding one of EXAIR’s ball valve or solenoid valves to turn off when you are done using it. Also, if you want to take it another step farther you can look at using one of EXAIR’s Electronic Flow Controllers (EFC). The EFC uses a photo eye attached to a timer that will open a solenoid valve for a set amount of time when it detects an object within 3’ of the photo eye. This will turn the air on only when your product is in the air path and turn it off during any spaces in between.
Compressor maintenance is another important step to minimizing the cost of compressed air. Neglected air compressors can cause a lot of issues ranging from expensive repairs to a decreases in efficiency. Wear and tear placed on the motor of an air compressor can cause the compressor to produce less compressed air (SCFM) at the same power consumption. This means you are paying the same amount of money and getting less out of it. Making sure that your compressor or any machine is always running at its optimal performance and should always be a priority for any facility.
There are many different ways to save on compressed air, these are just a few of them. Reducing air use will save money and reduce the demand on your compressor which in turn can prolong the life of your air compressor. If you have questions about how to save on compressed air or any of our engineered Intelligent Compressed Air® Products, feel free to contact EXAIR or any Application Engineer.
When I was working summers during school years I remember working in environments that were in unsatisfactory conditions. Since I was the the new kid and did not have seniority I had to take on the jobs that nobody wanted and therefore had the less than perfect working conditions. This company had a solvent welding process that at the time used Methyl Ethyl Ketone (MEK) as the bonding agent for ABS substrates. If only they knew about Air Amplifiers then! The solvent vapors on a hot humid Summer day would build up and I had to keep up with the quota while feeling a bit dizzy and disoriented! I couldn’t even run a fan as they were nervous blowing contaminants onto the substrates before going into the paint room. This is where a Super Air Amplifier could have helped.
Air Amplifiers are used for various reasons but in the story above could have been used for ventilation and keeping a safer work environment. Along with ventilating gasses/fumes these can be used for cooling hot parts, drying wet parts, cleaning machined parts, venting weld smoke, exhausting tank fumes, distributing heat within molds/ovens (circulation) and more! Super Air Amplifiers use the Coanda effect, a basic principle of fluidics, to create air motion. Using a small amount of compressed air as the source of power, the Super Air Amplifier then pulls in a large volume of surrounding air to produce high volume, high velocity outlet flows up to 25 times greater than the compressed air source.
Air Amplifiers have no moving parts making them virtually maintenance free to operate. No electricity is required. The flow, vacuum and velocity are easily controlled. Gross outlet flows can be adjusted by opening or closing the compressed air gap, which determines the amount of compressed air used. Supply air pressure can also be regulated to fine tune the outlet flow to meet application needs. Both vacuum and discharge ends of the air amplifier can be ducted, making them ideal for drawing fresh air from another location, or moving smoke and fumes away.
EXAIR carries a variety of sizes and styles and will even custom make Air Amplifiers for your every need. If you have questions about Air Amplifiers and want to talk to any of of many Application Engineers please contact us by calling 800.903.9247 or visit our website at www.EXAIR.com.
EXAIR offers 5 different styles of Safety Air Guns with a large variety of Safety Air Nozzles; VariBlast Precision, VariBlast Compact, Soft Grip, Heavy Duty and Super Blast. They range from small precise blowing up to large surface cleaning. First, the EXAIR Safety Air Guns are designed to meet OSHA standards for dead-end pressure and noise level. Second, the engineered nozzles improve efficiency of compressed air use; saving you money. In this blog, I will cover our largest air guns; the Super Blast Safety Air Guns.
The Super Blast Safety Air Guns are ideal for wide area blow-offs and far distances. They feature a comfortable foam grip and an auto shut-off trigger. The trigger valve has a spring that will turn off the airflow if the gun is dropped, to prevent backlash or the hose flailing around dangerously. Aluminum extensions are available in 36″ (0.9 meters) or 72″ (1.83 meters) lengths for hard-to-reach areas. These units use our larger Super Air Nozzles and Super Air Nozzle Clusters, providing forces levels from 3.2 lbs. (1.45 Kg) up to 23 lbs. (10.43 Kg). Depending on which nozzle is fitted on the assembly, air inlets can range from 3/8 FNPT up to 1-1/4 FNPT.
EXAIR offers two styles of nozzles in the Super Blast family; a Super Air Nozzle Cluster and a single Super Air Nozzle. Both are designed to entrain ambient air at a ratio near 25:1. That means for every 1 part of compressed air, the nozzle will bring in 25 parts of free ambient air. This will reduce the amount of compressed air required. The ambient air will add mass to give it a hard-hitting force. The Super Air Nozzle Cluster has an aluminum body with multiple Zinc-Aluminum Safety Air Nozzles nested. We offer a cluster with 4 nozzles, 7 nozzles, and 12 nozzles. The air pattern is wide to help remove debris quickly. The air blow guns with a single Super Air Nozzle are great for a more focused force at longer distances. EXAIR offers five different nozzle sizes to create the largest force within our Safety Air Guns at 23 lbs. (10.43Kg) at 80 PSIG (5.5 bar). Some applications would include cleaning large CNC tables, dump trucks, walls, ceilings, and sheets of materials.
For U.S. and Canadian customers, EXAIR will be giving away a 1” Flat Super Air Nozzle with a purchase of a VariBlast Precision, VariBlast Compact, Soft Grip, Heavy Duty, and Super Blast Safety Air Gun. EXAIR will send a model 1126 nozzle, a $50.00 complimentary gift, with a qualified purchase online until September 30th, 2021. EXAIR also offers a 30-day unconditional guarantee on our cataloged items to try. You can see for yourself on how effective these compressed air guns can be. If you need help to match the best Safety Air Gun to your application, an Application Engineer will be happy to assist you.
EXAIR’s Sanitary Flange Line Vac is the ideal solution for customers looking to convey bulk materials in food & pharmaceutical applications (among others). Operating in the same manner as EXAIR’s smooth and NPT threaded Line Vacs, the Sanitary Flange Line Vac is available in (4) common flange sizes: 1-1/2”, 2”, 2-1/2”, and 3”. All of EXAIR’s Sanitary Flange Line Vacs are constructed of Type 316 Stainless Steel for superior corrosion resistance.
There are different styles of flanges in industry. The Sanitary Flange Line Vac has been designed according to the flange standard outlined in ISO 2852. This standard was prepared by Technical Committee ISO/TC 5, Ferrous metal pipes and metallic fittings, Sub-Committee SC 1, Steel tubes. This is the second edition that replaces the first edition (ISO 2852:1974). The standard specifies the dimensions, tolerances, surface roughness, materials, assembling, and the hygienic requirements for the flange. These styles of flange are intended to be used with stainless steel tubes, specified in ISO 2037. ISO 2852 is considered an international standard, defining the connections used for non-permanent food-grade piping systems used within the pharmaceutical, food processing, dairy and agricultural industries.
In these industries, it’s required for the components to be thoroughly cleaned and sanitized. Using this type of connector, components within the piping system can be easily removed, sanitized, and then reassembled. A lipped flange with a grooved indentation is on each end of the pipe or Line Vac. A sealing gasket is then placed in between each section of pipe. A raised groove on either end allows it to seat onto the mating end of each flange. A clamp is then placed on the outside, forcing the sections together and compressing the gasket, creating an air-tight seal.
If your processes currently utilize sanitary flange piping, EXAIR’s Sanitary Flange Line Vac is the ideal solution to help you convey bulk materials from one point to another quickly, safely, and efficiently. If you have interest to test one out in your process, EXAIR offers an Unconditional 30 Day Guarantee on all stock items. They’re on the shelf now available to ship same day with an order placed by 2:00 ET!
