Standards, Compliance, And You. And EXAIR.

I’m pretty impressed with the number of safety features my car has. Aside from the literal lifesaving functions like seat belts and air bags, it’s got anti-lock brakes…if you’ve ever had to counter-steer out of a skid on an icy road, you will appreciate the value of this for sure.  Those are just some of the ones I’m keenly aware of – the Federal Motor Vehicle Safety Standards comprise dozens of regulations in three categories: crash avoidance, crashworthiness, and post-crash survivability.  None of these prevent me from operating my vehicle at an unsafe rate of speed…an expensive reality that an Ohio State Highway Patrolman dutifully reminded me of last Sunday afternoon.

Likewise, there are many regulations to ensure safety and prevent hazards of all kinds in industry, administered by a host of agencies that are either subordinates of, or accountable to, the federal government.  When you manufacture products that are used with high energy sources (compressed air or high voltage electricity,) a strong commitment to safety is not negotiable.  So, at EXAIR, we commit considerable resources towards the best engineering and manufacturing practices to make our products as safe as possible.  That includes compliance with a number of standards and certifications:

The Occupational Safety and Health Administration (OSHA) is an agency of the U.S. Department of Labor.  Their mission is to “assure safe and healthful working conditions for working men and women by setting and enforcing standards and by providing training, outreach, education and assistance.”  They are a regulatory body in the truest sense, in that they don’t offer certification or approval of products, processes, etc.; they publish guidelines and standards for manufacturers and users to comply with.  OSHA Standard 1910.242(b), for instance, limits the downstream pressure of a compressed air operated device used for cleaning purposes to 30psi. Now, you can regulate the supply pressure to meet this, but that also limits the effectiveness of the air flow generated.  EXAIR Intelligent Compressed Air Products are all designed and manufactured to be in compliance with this standard, at any supply pressure.  Take, for example, our Super Air Nozzles:

Because none of our products can be dead-ended, there’s always a relief path preventing the downstream pressure from exceeding that level.

OSHA also has Standard 1910.95(a), that sets limits for maximum allowable noise exposure.  All EXAIR Intelligent Compressed Air Products, with the exception of some our largest and most power Super Air Nozzles (which aren’t normally used in areas that don’t already require hearing protection anyway) meet the 8-hour exposure limits of this standard.

Hearing loss is the best known, but not the only, ill effect of harmful noise exposure. It can also cause physical and psychological stress, impair concentration, and contribute to workplace accidents or injuries.

CE marking indicates conformity with health, safety, and environmental protection standards for products sold withing the European Economic Area.  Unlike OSHA standards, responsibility for CE marking falls solely with the seller of the product – a CE marked product has been tested and certified to have been made in such a way to meet safety & quality benchmarks specified for that type of product.  All EXAIR products that are defined under applicable directives have been tested according to these standards, and carry the CE mark.

The Restriction of Hazardous Substances Directive, or RoHS, is another standard borne from the European Union, and is geared towards public & workplace safety by restricting the use of hazardous materials in the manufacture of electronic & electrical equipment.  Since its inception in 2006, similar standards have been vigorously adopted around the globe.  Electrical portions of EXAIR’s Static Eliminators, EFC Electronic Flow Controls, ETC Electronic Temperature Controls, Digital Flowmeters, Solenoid Valves, and Thermostats all comply with the RoHS Directive.

Section 1502 of the Dodd-Frank Wall Street Reform and Consumer Protection Act doesn’t address a concern for product users, but rather a particularly troubling human rights issue – Conflict Minerals.  For almost two decades, trade in tin, tantalum, tungsten and gold in the Democratic Republic of the Congo (DRC) has been used by some very bad people to finance violent campaigns against their neighbors.  EXAIR thoroughly and systematically documents our supply chain compliance with this act.  We are proudly committed to our support for this effort to the world a better place for everyone…especially those in desperate circumstances beyond their control.

EXAIR Intelligent Compressed Air Products have been successfully implemented into a variety of uses where application- or industry-specific standards are in force.  We’re happy to work with you to determine if our products meet those standards…or can be made to meet them.  If you’ve got such an application, give me a call.

Safety Air Guns – True Cost of Ownership

There are many inexpensive, cheaply made air guns out on the market.  If evaluated solely on purchase price, the decision of what air gun to buy seems obvious.  Only when you consider all the cost of ownership and operation, does the best direction become apparent.

A popular thumb lever operated air gun, readily available online has a base purchase price of $6.11.  The List price of the EXAIR model 1210 Soft Grip Safety Air Gun is $81.00. Wow- big difference you think, I am surely not going to spend that kind of money on a simple air gun.  Let’s take a look of the true cost of ownership for each of the guns.

EXAIR Model 1210 Soft Grip Safety Air Gun

We tested both the model 1210 and the other gun utilizing our Efficiency Lab service. We tested at 80 PSIG of supply pressure and measured and recorded air consumption, force and sound levels. Results of this testing is shown below.

From the test data, the other gun is able to provide 9% more force, but at a cost of 35% greater compressed air consumption, 5.64 SCFM more, along with an 18 dBA sound level increase (a sound level where hearing protection is needed, an additional cost to be incurred.)

If we examine the compressed air consumption, we can calculate the yearly compressed air usage, considering 4 hour per day of operation, 5 days per week, for 50 weeks out of the year.

Capture

 

A general rule of thumb for industry is that 1000 SCF of compressed air costs $0.25 to produce.Capture

As you can see, after 1 year of operation the Soft Grip Safety Air Gun has already paid for itself with compressed air savings, not to mention significantly reduced sound levels, well within the OSHA Standard 29 CFR – 1910(a) for Maximum Allowable Noise Exposure. To read more about the OSHA Standard, see this EXAIR blog. An EXAIR Safety Air Gun will continue to bring you benefits after this ROI period, and includes many other feature you do not receive with the cheap air gun.

You get the EXAIR 5 Year Built to Last Warranty which covers defects in workmanship and materials.  EXAIR’s safety air guns lead the way in standards and certification – we meet or exceed relevant OSHA standards, carry the CE mark and utilize a conflict mineral free supply chain.  We offer (5) types of Safety Air Guns, all offering ergonomic, comfortable, lightweight operation.

Safety Air Guns are also available with optional Chip Shields and Extensions (in lengths of 6″ to 6′) along with many different nozzle sizes (2.5 SCFM to 460 SCFM of air flow) and a variety of materials (Zinc Aluminum alloy, Stainless Steel, brass and PEEK plastic) to allow the configuration of the best air gun for your application.  EXAIR Safety Air Guns are great for use in applications ranging from light dust removal from delicate circuit boards to large scale, long distance, wide area blow off, cooling and drying applications and everything in between.

Be sure to check out the new VariBlast Compact Safety Air Gun for variable flow with the squeeze of the trigger!

If you have questions regarding the Safety Air Guns, 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 Product Standards

Standards seem to continually get introduced and updated. There is an ever increasing number of local, regional, federal, and even global standards to comply with.  We pay close attention to these standards and have the largest number of standards upon our products.

meets or exceeds oshaThe standards the every EXAIR product meets or exceeds are the OSHA standards for dead-end pressure as well as allowable noise level exposure.  The dead-end pressure directive is OSHA standard 29 CFR 1910.242 (b).  The standard refers to the fact that compressed air can be dangerous when the outlet pressure of a hole, hose or copper tube is higher than 30 psig (2 BAR).  In the event the opening is blocked by a hand or other body part, air may enter the bloodstream through the skin, resulting in a serious injury.  All of the compressed air products manufactured by EXAIR have been designed for safety.  All are safe to be supplied with higher pressure than 30 psig and still meet or exceed the OSHA standard.

The OSHA standard 29 CFR – 191.95 (a) refers to the maximum allowable noise exposure that an operator is permitted to be exposed to for a given period of time.   The chart of allowable exposure times is shown below.   All EXAIR products are engineered to create the minimum amount of noise while efficiently utilizing compressed air.   Many times blow offs are cross drilled to permit air to escape in order to meet the OSHA standard for dead end pressure, this process increases the noise level generated by that blow off considerably.

OSHA Noise Level

One of the most stringent compliance that EXAIR has upon its products is the UL/CUL listings and recognition.  All EXAIR Cabinet Cooler Systems are UL listed, we were the first to insure your electrical cabinet’s NEMA integrity remained by putting our Cabinet Cooler systems to the UL test. This means that the Underwriters Laboratories have deemed these products safe for operation throughout the US and Canada per their standards that are applicable for each of the product groups.   The products undergo numerous tests and scenarios to ensure that an operator will be safe during the normal operation of the units.   The tests for the Cabinet Cooler Systems includes environmental exposure for the given NEMA type of the enclosure along with many other tests.  The Static Eliminator Power Supplies are also UL listed.

CE is another standard which EXAIR pays great attention to to meet or exceed. CE is a standard that is normally preferred when dealing with countries outside of the US but is gaining popularity within the states as well.  CE being a European standard actually stands for a french phrase, “Confrmité Eurpéene” which is translated to “European Conformity”.  Any EXAIR product displaying the CE mark conforms where there are applicable directives.CE

The RoHS directive is targeted on heavy metals that are generally found within electronics.  Substances like Mercury, Lead, Polybrominated biphenyls, Cadmium, or Hexavalent chromium.  In order to meet the RoHs directive a product must have 100 parts per million or less of mercury and for other substances there must be less than 0.01% of the substance by weight in a raw homogeneous materials level. All EXAIR products which are electronic or contain electronic devices are compliant to the 2002/95/EC RoHS directive, also including the amendment outlined in the European Commission decision L 214/65.  This includes all EXAIR Static Eliminators, Electronic Flow Control, and Electronic Temperature Control products.ROHS_Vector

EXAIR maintains records to be sure our supply chain is providing product which meets the conflict mineral free guidelines of the Dodd-Frank Act.  EXAIR supports Section 1502 of the Dodd-Frank Wall Street Reform and Consumer Protection Act and we are committed to compliance with the conflict minerals rule in order to curb the illicit trade of tin, tantalum, tungsten and gold in the DRC region. EXAIR is using the CMRT 3.02 template to document our supply chain and commitment to conflict free products. When requested we will even provide the needed forms to support our customer’s efforts in complying with the Dodd-Frank Act.

conflictfree

REACH, is another European Community Regulation this time on chemicals and their safe use.  REACH is targeted to ensure personnel and environmental health by identifying the intrinsic properties of chemical substances easily.  REACH stands for Registration, Evaluation, Authorization and Restriction of Chemical substances and was written into law in 2007. EXAIR products are not required to be registered per Title II, Article 7, paragraph 1  of the legislation since they do not contain substances that are intentionally released.   This is to ensure compliance with Regulation (EC) No 1907/2006 Title I, Article 3, paragraph 3, the European Union requires registration of chemicals and substances imported into the EU to ensure a high level of protection of human health and environment.
