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 Leads the Way with Standards and Certifications

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!

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.

Super Ion Air Knives Remove Dust from Plastic Panels

20160426_134447

Conveyor line with static dust problem

One of our distributors reached out to me this week about a static elimination application in Russia.  The end user has the setup shown above, and they are in need of a means to remove dust from the plastic panels on the conveyor.  These panels have a static charge causing ambient dust to adhere to their surfaces.

The main questions for this application were whether we could provide a solution capable of creating a static eliminating blow off for the entire width of the conveyor (approx. 54”), and whether the dust particles can be removed from the working area after removal from the plastic panels.

In order to answer the first question we first had to select a solution, and the Super Ion Air Knife is a near-perfect fit.  We can provide Super Ion Air Knives in any length up to 108”, with a stock length 54” unit available on the shelf.  This was a straightforward recommendation to remove the static from these plastic sheets – install one 111054 54” Super Ion Air Knife on the top and bottom sides of this conveyor to remove the static and blow off the dust.  But, the second question will require a more specialized solution.

When static causes dust to adhere to a surface, removal of the static charge allows the dust to fall off or be blown away, so we were confident that we can remove the static and dust.  But, we then need to vacuum these dust particles away – something we could achieve with a series of Super Air Amplifiers or Line Vacs – which will require some sort of specialized hood.  Fortunately for us, this application already has a vacuum control system with a hood (you can see this in the right side of the photo with a large plastic air duct running to the top and bottom hoods on this conveyor line).

So, problem solved!  We recommended the two Super Ion Air Knives are installed with the airflow aimed at a 45° angle of attack, opposite the direction of travel, and with the airflow aimed into these vacuum hoods.

If you have a similar application or static problem in your facility, give us a call, we’ll be happy to help.

What’s an EXAIR?

Sometimes taking customer’s phone calls remind me of an Abbott and Costello bit (but I have to be Costello). Conversations can feel a bit like twenty questions. Instead of opening with mineral, vegetable, or animal, customers call in wanting more information on an “EXAIR”.  For our brand manager and marketing department, it is a clear sign that what they are doing is working, but to me can be a bit confusing.

Before you start thinking I don’t know my product, please remember an “EXAIR” can be quite few things. We make the broadest variety of problem solving end-use compressed air products for industry which equates to many possibilities of what an “EXAIR” may be. Is it an Air Nozzle, an Air Knife, an Air Wipe, an Air Amplifier, an Atomizing Spray Nozzle, a Safety Air Gun, a Static Eliminator, a Vacuum Generator, a Line Vac, an Industrial Vacuum, a Vortex Tube, a Cold Gun, or a Cabinet Cooler?   Unfortunately, with no moving parts to wear out, our products sometimes will outlast their labels, so the customers don’t have anymore information. Then, I have to ask what the product does.

So I ask the customer, “does the EXAIR blow off, vacuum, clean, dry, cool, convey, evacuate, coat, divert, dust, float, open, lift, purge, or spray?”

And then I wait for the customer’s detailed and eloquent response…”It works”, they sometimes say. But most of the time they respond with all of the details or enough to determine what product they have. In, in the end, an “EXAIR” is generally a Cabinet Cooler or a Vortex Tube (though it may be any of the above selection) – and we won’t complain that our company name can be so closely associated with our products.

We have so many products because compressed air is so versatile and useful.  We have taken our expertise in compressed air and used it to solve numerous problems for our customers. This is not as easy, as it sounds.  First, you need to know how well our compressed air products can perform. Second, you need to know what kind of performance the customer needs to get the job done. For instance when working on a Cabinet Cooler sizing exercise: A customer has a control box that is 24″ tall by  36″ wide by 12″ deep.  This box is reaching temperatures that cause the electronics to fail. Generally, this temperature is going to be between 110 degrees Fahrenheit to 130 degrees Fahrenheit. The temperature in the plant was 95 degrees Fahrenheit, when it failed.  The customer would now like a Cabinet Cooler System to protect his enclosure from future temperature failures.

To calculate the heat load of the electronics, first we need to calculate the surface area in square feet. In the example above that would be 22 square feet. Second, we need to calculate the temperature differential between the outside and the inside of the cabinet.  The maximum temperature differential is 130 F – 95 F, which is 35 degree differential. With the temperature differential chart from our website, we can calculate the BTU/HR per square foot.

Temperature Conversion Table

For our example, it would be 13.8 BTU/HR/ft^2. Multiply this by our surface area. Our Cabinet Cooler needs to cool at least 303.6 BTU/HR. Our 4308 Cabinet Cooler System would be a good cabinet cooler for this enclosure. It can cool 550 BTU/Hr. It is rated for a NEMA 12 enclosure to prevent dust and oil from entering the cabinet.

To help the customer, you have to first ask the right questions. Most of these questions are listed on the Cabinet Cooler Sizing Guide on our website. What is the internal air temperature in the cabinet? What is the ambient air temperature? Are their any fans in the cabinet? What is the NEMA rating for the Cabinet? Sometimes it is best to speak with an Application Engineer to know for sure you have your bases covered.

Excellence Is Not An Act, But A Habit

“We Are What We Repeatedly Do. Excellence, then, is not an Act, But a Habit”

In my twitter feed I often see the aforementioned quote that is attributed to Aristotle. As this blog points out, the quote should really be attributed to Will Durant author of The Story of Philosophy, because it is his interpretation of what Aristotle would have said if he spoke English. While writing this blog I found out Aristotle didn’t really write the quote. In retrospect, clearly he didn’t write, if he did it might look something like this “Είμαστε Τι επανειλημμένα Do. Αριστείας, τότε, δεν είναι μια πράξη, αλλά μια συνήθεια”, but I digress.

Working with customers, resellers and catalog houses, I’m amazed at the different company cultures. Some customers will come to me six months before a project comes up to talk about the applications. They ask us for drawings, specifications, and certifications for the products that we recommend for their applications. They want to analyze all possible scenarios and plan for every eventuality.  These customers greatly appreciate our fully loaded knowledge base and availability of technical information.

Other customers call me for a quote and confirmation. They spent some time online, downloaded a CAD model and created a working plan, but before they pull the trigger, they want to run it by someone else. These customer greatly appreciate the fact that the phones are answered by human beings and we have a fully staffed Application Engineering department with engineers who are always eager to discuss applications and possibilities.

Finally, we have the customers, who I never spoke to before that need a product NOW and are willing to do anything to get. Shipping companies love these customers, because we have our products on the shelves ready to ship, but it will cost you air freight and a flux capacitor to get it there yesterday.

 

At EXAIR, our culture expects excellence. And no matter the kind of customer who contacts us, we know you are all trying to achieve it too – we are just trying to help. When our customer calls in to ask for something yesterday, we will already have it on the shelf ready to go. Unless it is a custom product, our production staff has already machined, built, and tested our product to our excellent standard.  I’m constantly amazed at the effort and continued excellence put out by customer service, engineering, marketing, and production. When the customer calls in to ask for product yesterday, 99.98% of the time I’m able to say that the shipment will be at the dock waiting for the shipping truck by 3:00 PM EST. We can typically do that without an extraordinary effort, because we practice excellent customer service everyday. It’s a habit we are not trying to quit.
