Custom Products Designed Just for Your Application

Because EXAIR designs and manufactures our own products, if you need something a little different we can probably help. This is true throughout our entire product line, the following examples are of our Line Vac products.

Do you have an application that may not be best served by one of our stock Line Vac products? While we have quite a variety of both materials, sizes, and connection types sometimes a special application requires a special solution. For this reason,  EXAIR manufactures special Line Vacs suited EXACTLY for the type of application or environment that it’ll be operating in.

This special Miniature Line Vac was manufactured with barb fittings and designed for a manufacturer of integrated circuit chips. It was used to remove microscopic debris during the chip making process. It’s small overall footprint makes it ideal for applications requiring tight mounting conditions. It has also been used by other manufacturers to vacuum liquid and chips from small drilled holes. While the Line Vac isn’t typically suitable for liquids, the higher vacuum level associated with the smaller Line Vacs makes it a possibility.

This next special Line Vac was used to convey fine powders or granulated materials from a hopper. While this is a pretty straight-forward application for a standard Line Vac, their material could sometimes be moist which would pack the tube and restrict the flow of material. The funnel-shaped design created a suction on the existing tube that permitted a continuous product flow.

This flanged Line Vac was used to retrofit existing machinery to remove acidic vapors resulting from surface etching of a silicon wafer. Where this would typically be a nice fit for a Stainless Steel Air Amplifier, the existing exhaust piping was lengthy with many bends that would have caused back pressure on any Air Amplifiers. In this case, they needed the high velocity airflow from the directed nozzles of the Line Vac to overcome this downstream resistance.

In addition to making Line Vacs in different shapes and sizes, we can also use special materials. In this instance, the special flanged Line Vac was manufactured out of PVDF (Polyvinylidene Flouride) due to its superior corrosive resistance. The Line Vac would be regularly exposed to a chloride wash that would corrode even stainless steel. It was also manufactured with special QF flanges to allow for easy assembly and removal of the conveying hoses for cleaning purposes.

As you can see the sky is the limit when it comes to potential styles of Line Vacs. Don’t think just because you don’t find something you need in the catalog that EXAIR can’t do it! We’ll create special manufactured products for just about anything that you can find in the catalog, not just the Line Vacs. Whether it’s custom-length Super Air Knives or special Air Amplifiers we can make it happen. Reach out to an Application Engineer today for help designing a solution, just for YOU!

EXAIR Safety Air Gun Promotion

From August 1st to September 30th, 2018, EXAIR will be giving away a 1” Flat Super Air Nozzle with the purchase of any promotional VariBlast, Soft Grip, or Heavy Duty Safety Air Gun.  EXAIR is stressing the importance of safety in the workplace with the EXAIR Safety Air Guns as well as the versatility of the different types of EXAIR Super Air Nozzles.

SAGpromoAD_500xsq

This promotional item, the model 1126 1″ Flat Super Air Nozzle, has a patented shim to blow a 1” wide stream of air to clean surfaces quickly and efficiently and is a $45.00 USD value. For more details on the Promotion, click on the photo/link above. For more information about the Flat Super Air Nozzles, click HERE.

Inexpensive air guns can be purchased just about anywhere- online, via catalogs, and through industrial supply companies. Typical quality is less than ideal – broken triggers, leaky valves – a short lifespan in an industrial setting are merely a few of the issues observed.  Most are loud and inefficient – they just blow large amounts of compressed air, and at noise levels that violate OSHA requirements.  Some may even generate dangerous dead end pressure situations that that can result in serious or fatal injuries if blocked.

EXAIR’s Safety Air Guns have been engineered and designed to eliminate these issues. They are durable for use in industrial situations and comfortable to use for extended periods of time.  With an EXAIR engineered air nozzle, each model provides top performance by entraining large volumes of surrounding air into the air-stream. Operation is assured to be safe along with low compressed air consumption and noise levels.  Due to the design, the airflow that exits the nozzle cannot be blocked, as required by OSHA Standard 29 CPR 1910.242(b).

Safety Air Guns
The EXAIR VariBlast, Soft Grip and Heavy Duty Safety Air Guns

The VariBlast style of safety air gun offers variable force based on the range of trigger pull. Force can be varies, form a light breeze, to full force maximum output. This cast aluminum air gun can be fitted with any of the EXAIR 1/8 NPT engineered air nozzles.

The Soft Grip style of safety air gun  has a durable cats aluminum body suited for rugged, industrial use. The ergonomic design has a soft vinyl cover, a large trigger for easy operation, and a hanger hook for easy storage.

The Heavy Duty style of safety air gun is powerful with a durable aluminum cast body and ergonomic composite rubber grip, best suited for rugged industrial environments. Hours of fatigue free operation are possible.

With all of the Safety Air Guns styles, Chip Shields and Extension Pipes are available, from 6″ to 72″ in length.

With many nozzle options, from a whisper quiet 58 dBA and 2.5 SCFM of flow up to 60 SCFM and 87 dBA (still below the OSHA 8 hour noise level threshold) there is a model that will fit practically any application. Application Engineers are available by phone, email, and chat to review your specific blow off needs, and help to select the best possible solution available.

We invite to you to try out an EXAIR Safety Air Gun, and get the free 1″ Wide Flat Super Air Nozzle as a bonus.

Better Understand Your Blowoff Process with EXAIR’s FREE Efficiency Lab

The EXAIR Efficiency Lab

Many customers may not have the means to test the air consumption of their blowoff solutions. With compressed air being the most expensive utility in a manufacturing facility, it’s important to identify places where you can save money on your overall operating costs. EXAIR manufacturers a wide variety of products intended to help you reduce your compressed air usage. If you’re not able to accurately measure the consumption in your own shop, we invite you to send the products into EXAIR for testing. With EXAIR’s Award Winning Efficiency Lab, just simply contact an Application Engineer, box them up and send them to our warehouse in Cincinnati, Ohio.

EXAIR Efficiency Lab

Once we receive it, our engineers will complete some in-depth testing to determine the compressed air consumption, sound level, and force that your current solution provides. With this information, we’ll be able to compare it to an EXAIR Engineered Solution. This way we ensure that you receive the best, safest solution possible also capable of saving money through reduced air consumption and improved efficiency.  We’ll send you back a comprehensive report that’ll help you to make the best decision for your company.

I’ve been recently working with a customer that sent in one of the nozzles they’re using across all their CNC machines. They wanted us to test it out and see if we’re able to offer them something that could reduce their overall compressed air usage. The nozzle was one of the cheap plastic varieties and was attached to a commonly used modular hose. This type of modular hose is not designed for operating under high pressures. These hoses are more suitable for liquid coolant or air that is at or below atmospheric pressure.

Inefficient and unsafe plastic nozzle

After testing, we found that at 80 psig the nozzle consumed 3.85 SCFM and produced a force of 1.92 oz. We also noticed that after 60 psig, the nozzle began to leak due to a poor seal where the nozzle met the brass hex. The EXAIR nozzle most suitable to replace this was the 1108SS. At just 2.5 SCFM at 80 psig, replacing the plastic nozzle with an engineered solution saves them 35% of their overall consumption for this blowoff. With close to 1000 of these nozzles in operation, that adds up quickly!!

In addition to increasing efficiency, replacing these nozzles also greatly increases overall worker safety. The sound level is reduced from 73 dBA to just 58 dBA and EXAIR’s nozzles also adhere to OSHA 1910.242(b). The plastic nozzles could be dead-ended, posing a hazard that can result in costly fines. These fines are assessed per infraction, so having multiple non-compliant nozzles can easily get very expensive if you’re subject to an unannounced visit by an OSHA inspector.

If you think you may have an opportunity to improve upon your existing blowoff methods, give us a call. We’ll be happy to take a closer look and have you send the product back to EXAIR for a quick trial in our Efficiency Lab. You’ll be glad you did!

The Case For The Adjustable E-Vac Vacuum Generator

Vacuum generation is vital to many industrial processes:

*Pick-and-place. Vacuum cup systems are used to move metal sheets onto laser & plasma cutting beds, precisely place parts for assembly using end-of-arm robotic tooling, or moving awkward objects, like plates of glass, by hand.

The same Adjustable E-Vac Vacuum Generator can be used for a range of products, from the cinder bloc (left) to small pavers (right.)

*Bag/package opening.  When plastic bags come off a roll and are fed through an automated filler, vacuum cups can make quick work of opening them up, immediately before the filling operation.

*Vacuum filling.  A closed container can be easily filled, without a pump, by simply drawing a vacuum on it.  Same mechanism (and simplicity) as when you drink a beverage through a straw.

These are just a few of the typical uses for an EXAIR E-Vac Vacuum Generator…I’ve written before about how this is our most versatile product line (by number of different applications) but these in particular are the ones I want to use to make the case for the Adjustable E-Vacs.

EXAIR Adjustable E-Vac Vacuum Generators are available in four distinct models, depending on the needs of your application.  Performance is variable not only by regulating the air supply pressure (like any compressed air product) but also by threading the plug into the body, which changes the size of the annular gap that feeds the Venturi, changing the vacuum and flow levels.  This can be used to overcome vacuum loss due to material porosity or vacuum cup leakage in a pick-and place application, to accommodate different bag sizes or types in an opening application, or to change the rate at which a liquid is moved in a vacuum filling operation.

With four to choose from, EXAIR has an Adjustable E-Vac that will fit your vacuum generating needs.

Because of their larger throat diameter, they’re also better suited for situations where particulates or moisture may be entrained…they won’t clog or ‘stall out’ as is common with other Venturi-type products.  This is especially useful in vacuum chucking/clamping, or when contaminants from dirty environments can make their way into the system.

EXAIR E-Vacs provide instantaneous vacuum response, and are engineered for high efficiency to minimize air consumption.

Like EXAIR In-Line Vacuum Generators, they instantly develop rated vacuum as soon as compressed air is supplied, so they’re well suited for fast moving operations.  With no moving parts, they’re durable, effective, and if you feed them with clean, dry air, they’ll operate a good long time, virtually maintenance free.

If you have a vacuum generating application you’d like to discuss, please give me a call.

Cabinet Cooler NEMA Ratings Explained

CC_Actionshot

Temperatures are heating up across the US, when this happens it can wreak havoc on the sensitive electronics in your facility.  If you’re a follower of the EXAIR Blog, you’ve noticed that we’ve spent a great deal of time recently discussing the Cabinet Coolers. From a description of how they work, specific applications, as well as how to determine what size you’ll need, we’ve covered quite a range of topics. Equally important, though, is the NEMA rating of the Cabinet Cooler. I’d like to take a moment to discuss the different NEMA ratings for the Cabinet Coolers that EXAIR has to offer and where each should fit.

cc_heroi9_308x308
EXAIR’s Model 4008 Nema 12 Cabinet Cooler

NEMA 12 – The NEMA 12 rating is for enclosures that are indoor and provide a degree of protection to personnel against access to hazardous parts as well as prevent any materials from entering the enclosure such as dust, debris, or moisture from light splashing. This standard duty style of Cabinet Cooler is best served indoors on the shop floor where there aren’t any wash-down areas or excessive moisture.

NEMA 4 – A NEMA 4 rated cabinet cooler is designed for either indoor or outdoor use. It, too, provides protection to personnel against access to hazardous parts and prevents dust, dirt, or debris from entering the cabinet. In addition to providing the same levels of protection as the NEMA 12, the NEMA 4 rating also means that the equipment will be protected from water such as rain, sleet, snow, splashing water, and even hose directed water.

Model 4880SS-316

NEMA 4X – The NEMA 4X carries the same levels of protection as the NEMA 4, but also adds an additional level of protection against corrosion. EXAIR’s NEMA 4X Cabinet Coolers are constructed of either 303 or 316 Stainless Steel.

EXAIR’s Cabinet Coolers are available from stock with cooling capacities ranging from 550 Btu/hr – 5,600 Btu/hr. With a variety of different materials and NEMA ratings, EXAIR has the right Cabinet Cooler ready to ship today to prevent your sensitive electronics from shutting down.
