Calibration – Keep Your Meters True

EXAIR offers meters to measure the level of physical parameters such as sound and static. Each meter has sensitive electrical circuitry and a periodic calibration is recommended to ensure the meter readings are tried and true.

The model 9104 Digital Sound Level Meter is an easy to use instrument that measures and monitors the sound level pressure in a wide variety of industrial environments. The source of loud noises can be quickly identified so that corrective measures can be taken to keep sound levels at or below OSHA maximum allowable exposure limits.

The sound meter comes from the factory with an NIST (National Institute of Standards and Technology) certificate of accuracy and calibration.  As a good practice, EXAIR recommends a yearly calibration of the instrument, and we offer a service that calibrates the unit to the same NIST standards and provide a written report of the calibration.

The model 7905 Static Meter allows easy one-hand static measurements.  It is useful in both locating sources of high static charge and checking the reduction of static after treatment with an EXAIR Static Elimination product.  The unit is sensitive and responsive, and indicates the the surface polarity of objects up to +/- 20 kV when measured from 1″ away.

It is also recommended that the Static Meter be calibrated on a yearly basis.  EXAIR offers (3) levels of calibration service.  The first two provide calibration in accordance with MIL Standards using accepted procedures and standards traceable to NIST.  The third calibration service conforms to the same Mil Standard, as well as ISO/IEC standards.

Annual calibration service of your EXAIR Digital Sound and Static Meter, along with proper care and storage, will keep your meter performing tried and true for many years, providing accurate and useful measurements.

To initiate a calibration service, give us a call and an Application Engineer will issue an Returned Good number, and provide instructions on how to ship the meter to EXAIR.

If you have questions regarding calibration services for your meters or would like to talk about any EXAIR Intelligent Compressed Air® Product, feel free to contact EXAIR and myself or one of our Application Engineers can help you determine the best solution.

EXAIR Accessories – We’ve Got you Covered

When you work with us here at EXAIR, we strive to have all the ancillary items that you might need to make your installation a success, without having to find components at the last minute or perhaps using the wrong sized components. Each specific product line such as Super Air Knives or Line Vac air operated conveyors have specific accessories such as mounting brackets or plumbing kits which EXAIR has made to simplify the installation of those particular products. We also carry generalized accessories which work across all of the product lines so you do not have to use multiple vendors or purchase orders.

Silencing Mufflers – Per OSHA Standard 1910.95(a), a worker must not be exposed to sounds levels above 90 dBA for any eight hour shift of a 40 hour work week.  EXAIR offers several types of mufflers including – Reclassifying, Sintered Bronze, Straight-Through and Heavy Duty.  For reducing the noise associated with an EXAIR E-Vac Generator, Vortex Tube, Cabinet Cooler System, or the exhaust air from cylinders, valves and other air powered equipment, we’ve got a muffler that will help to keep the noise level at an acceptable level.

Mufflers

Solenoid and Manual Valves – The easiest way to reduce compressed air usage and save on operating expense is to turn off the compressed air to a device when it isn’t needed. EXAIR carries a wide assortment of solenoid valves, with offerings in the NEMA 4/4X classification, and supply voltages of 24VDC, 120VAC, and 240VAC.  We also have manual ball valves from 1/4 NPT to 1-1/4 NPT and a foot operated valve, with 1/4 NPT connections.

Valves

Swivel Fittings, Stay Set Hoses and Magnetic Bases – To provide a great degree of flexibility for positioning an EXAIR Super Air Nozzle, Air Jets or Air Amplifiers, EXAIR offers several items.  The Swivel Fittings have 25 degree of movement from the center axis, providing a total of 50 degree of adjustability.  The position is locked in place and holds until adjustment is needed. For applications where frequent re-positioning of the air device is required, the Stay Set Hoses are ideal.  Simply mount the hose close to the application, bend it to the shape preferred, and because the hose has “memory”, it will not creep or bend.  Lastly, the Magnetic Bases are another option for flexible, movable installations.  The base has a on/off valve, and a powerful magnet to hold in any vertical or horizontal mounting arrangement.

Hoses – EXAIR can provide hoses for your application.  For the Line Vac air operated conveyor applications, we offer conveyance hose – a durable, clear reinforced PVC hose, in diameters of 3/8″ to 3″ ID, and lengths up to 50′. On the compressed air side, we can provide 12′ Coiled Hoses with 1/8, 1/4, and 3/8 NPT connections, and also 3/8″ and 1/2″ ID hose in lengths to 50′.

Hoses

Filter Separators, Oil Removal Filters and Pressure Regulators – Perhaps the most important accessories for use on a compressed air device are filters and regulators. Filtering the compressed air of dirt, debris, moisture and oil will help to prevent build up inside the EXAIR products, leading to longer service life, and less time spent cleaning, while providing optimum performance. Regulating the air pressure allows for tuning of the performance, using the proper amount of compressed air to obtain satisfactory results.

Compressed Air Filtration – Particulate, Coalescing, and Adsorption Types

Compressed air systems will contain contaminants that can lead to issues and increased costs through contamination of product, damage to the air operated devices, and air line clogging and restriction. Proper air preparation is critical to optimizing performance throughout the plant operations.

Because there are different types of contaminants, including solid particles, liquid water, and vapors of water and oil, there are different methods of filtration, each best suited for maximum efficiency in contaminant removal.

Particulate Filters – The compressed air flows from outside to inside of the filter element. The compressed air first passes through a baffle arrangement which causes centrifugal separation of the largest particles and liquid drops (but not liquid vapors), and then the air passes through the filter element.  The filter element is usually a sintered material such as bronze.  The filter elements are inexpensive and easy to replace. Filtration down to 40-5 micron is possible.

Particulate Type Filter with Sintered Bronze Element

Coalescing Filters – This type operates differently from the particulate type.  The compressed air flows from inside to outside through a coalescing media. The very fine water and oil aerosols come into contact with fibers in the filter media, and as they collect, they coalesce (combine) to form larger droplets towards the outside of the filter element. When the droplet size is enough the drops fall off and collect at the bottom of the filter housing.  The filter element is typically made up of some type glass fibers.  The coalescing filter elements are also relatively inexpensive and easy to replace. Filtration down to 0.01 micron at 99.999% efficiency is possible.

9005

Coalescing Type Filter with Borosilicate Glass Fiber Element

Adsorption Filters – In this type of filtration, activated carbon is typically used, and the finest oil vapors, hydrocarbon residues, and odors can be be removed.  The mechanism of filtration is that the molecules of the gas or liquid adhere to the surface of the activated carbon.  This is usually the final stage of filtration, and is only required for certain applications where the product would be affected such as blow molding or food processing.

When you work with us in selecting an EXAIR product, such as a Super Air Knife, Super Air Amplifier, or Vortex Tube, your application engineer can recommend the appropriate type of filtration needed to keep the EXAIR product operating at maximum efficiency with minimal disruption due to contaminant build up and unnecessary cleaning.

What Makes Things Easier Than An EXAIR Static Eliminator? Another EXAIR Static Eliminator!

A contract manufacturer, servicing the medical and biotechnology markets, is a long time user of our Ion Air Guns. They’ve had great success with them in keeping their products free from static & dust for years. These are mainly small, hand-held parts, so, when they need to get them clean and static-free during assembly and packaging, EXAIR’s Ion Air Gun is ideal, because it, too, is small and hand-held.

A new process, though, involves the operator needing both hands for assembly. This would mean picking up the Ion Air Gun, blowing off the part, putting it down, and then using both hands to complete the operation. They thought there had to be a better way. And they were right!

The Model 8910 Instant Static Elimination Station offers hands-free control of ionized air flow – a foot pedal turns an Ion Air Jet (whose performance is identical to the Ion Air Gun) on and off with…well, the press of a foot. The Magnetic Base and Stay Set Hose make it easy to install, and even easier to position.

Hand held convenience of the Ion Air Gun (easy) or no-hands convenience of the Ion Air Jet Station (easier.) Your call.

Hand held convenience of the Ion Air Gun (easy) or no-hands convenience of the Ion Air Jet Station (easier.) Your call.

For an even more automated approach, they are considering an EFC Electronic Flow Control. They’re ready to go, right out of the box…the photoelectric sensor will open and close a solenoid valve (installed in the compressed air supply line) based on the setting of the programmable timer unit. With a simple wave of the part in front of the sensor, the operator could activate a preset blow of a few seconds, which would be easy to determine, even easier to set, and…easiest of all…reliably repeat all day long. They’re going to try out the foot pedal first, and that’s just fine by me.  Perhaps there’s such as thing as “too easy,” but man, I hope not.

Even if you’re already using EXAIR products to make things easy, you can call me to see how much easier it might get.

“(Stay) Set It And Forget It”

The Stay Set Hose is a popular, and practical, accessory for use with many of our blow-off products. Thread one end onto a compressed air supply connection, thread a Super Air Nozzle (or maybe even a small Air Amplifier or short Air Knife) onto the other end, and you’ve got an easily repositionable blow off…which will reliably hold its position.

That last part was of considerable importance to a caller I had the pleasure of assisting recently. Some of the CNC machines in their shop were fitted with flexible plastic tubing (commonly used for coolant & cutting fluid,) supplied with compressed air to blow off chips & debris from the tooling as the parts were being machined. They use our Super Air Knives in other blow off processes (where they used to use costly & loud open blow off devices,) and wanted to see if engineered products might reduce their compressed air consumption & noise levels in the machine shop too. (spoiler alert: Yes, they can.)

Thing is, they really needed the flexibility of the modular hose, but it’s not rated for the pressure supply required for a Super Air Nozzle. This is what makes our engineered products so efficient; they use the Coanda effect to amplify the compressed airflow..and they use the supply pressure to do that. So they can’t install a Super Air Nozzle on what they have now.

Enter the Stay Set Hoses: They’ll bend to direct the nozzles’ air flow right where you need it, and they’ll keep it there until you bend it again. Which (back to what’s most important to this caller) is exactly what they needed. With our efficient & quiet Super Air Nozzles, they’re saving compressed air and improving the conditions of their work environment. With the Stay Set Hoses, they’re able to quickly & easily rig the air flow before running a job, knowing they won’t have to worry about it until the job’s done.

EXAIR Stay Set Hoses hold their position as long as you need them to. All day, every day.
