EXAIR’s Safety Air Guns are the Ergonomic Answer

In addition to a variety of engineered Air Nozzles, you can customize your EXAIR Safety Air Gun with Chip Shields, Extensions, Stay Set Hoses, etc., to meet the particular needs of a specific application.

EXAIR has a nice selection of Safety Air Guns. The VariBlast Precision and Compact, Soft Grip, Heavy Duty and Super Blast Safety Air Guns are available with a variety of air nozzles, chip shields and pipe extensions. They are durable and comfortable and ergonomic to use.

These Safety Air Guns are designed with durability and comfort in mind while also ergonomically safe to use. Safe operation is assured along with low air consumption and noise levels.

EXAIR Engineered air nozzles are available in Type 316 stainless steel for superior corrosion resistance and mechanical wear, Type 303 stainless steel for corrosion resistance, PEEK thermoplastic for non-marring and chemical resistance or zinc/aluminum alloy for general purpose applications.

Flying Debris? – Chip Shields are durable polycarbonate shields that protect the operator from risk of flying debris often seen when blowing off chips from machined parts. They are also useful to prevent coolant from splashing back, creating a mess during drying processes.

The Chip Shields are available for EXAIR’s VariBlast, Soft Grip and Heavy Duty Safety Air Guns. The Chip Shield can be used on Safety Air Guns with or without an aluminum extension. They may be purchased as part of a new air gun system, or retrofitted as a Chip Shield Kit.  Consult an Application Engineer for selection assistance.

If you have a blow-off process where the air is to be directed at a distance away from the operator, or into a hard to reach location an extension is the solution. Available in lengths from 6″ (152mm) to 72″ (1829mm), with sizes as to meet most requirement can be found. To add an extension to an air gun, simply add -xx to the current part number..

EXAIR’s Stay Set Hoses are available from 6”-36” in lengths with ¼ NPT male threads on each end, or a ¼ NPT male on one end and 1/8 NPT female on the other. The Stay Set Hoses are rigid and allow you to maintain precise positioning of the blow off nozzle. The hoses have “memory” and will not creep or bend.

 If you need a 12′ coiled air hose, to use with your Safety Air Gun, we have them available and in stock. Available with 1/8 NPT, 1/4 NPT or 3/8 NPT male end swivel connections. Avoid tangled and messy air lines and keep things neat!

EXAIR Case Studies Share Succe$$

EXAIR provides many informative tools to help you decide which of our products will work best for you. We have a qualified staff of Application Engineers, a comprehensive catalog, Installation Sheets, Blogs, and a library of Case Studies, to name a few. Following is more about our Case Studies and how they can be helpful.

EXAIR keeps a library of Case Studies for your reference. The Library s is also organized by product so you can easily find the information and product you have interest. These case studies summarize how our customers have purchased, used, and benefited from our products and their purchase. These studies focus on our products and your project, we do not use our customer names and only use photos and verbiage that you approve and share with us.

The process to develop a Case Study is as easy as talking to one of our Application Engineers. We will discuss your project and work with you to decide the wording and photos that you approve for the study. Once the study has been completed and approved we can discuss a credit on your purchase or percentage discount on your next purchase. This becomes a “win, win” for both you and EXAIR.

EXAIR appreciates a good success story, and we want to encourage you to share your success from using one or more of our products. This is why EXAIR incentivizes Case Studies. We will offer a discount to any company who will provide enough information to produce a case study. If you have interest to create a Case Study (and save money) on your next project please contact one of our Application Engineers so we can discuss your application and goals.

Laminar and Turbulent Air Flow

I have a manufacturing background primarily with automotive and plastic injection molding. I used compressed air but I will admit that I did not know the difference between Laminar and Turbulent air flow. You’ll often hear EXAIR refer to laminar vs turbulent flow when discussing our blow off of products. I will briefly describe the difference between the two and hopefully we all learn something new. In any blow off process or application, laminar airflow is going to be much more effective at eliminating pressure drops, blowing product and reducing noise levels than the turbulent air flow. To read more about the math behind it, check out my colleague John Ball’s previous post here.

A good example of an EXAIR product that delivers a laminar air flow are our Super Air Knives. The super air knife offers a more efficient way to clean, dry or cool parts, webs or conveyors. They deliver a uniform sheet of “Laminar” airflow across the entire hard-hitting force. The Super Air Knives deliver a uniform sheet of air that has the same force across the entire length.

The efficiency of EXAIR’s Super Air Knife delivering the laminar air flow becomes more valuable when comparing the effectiveness to a blower operated knife or fans. A fan “slaps” the air, resulting in a turbulent airflow where the airflow particles are irregular and will interfere with each other. A laminar airflow, by contrast, will maintain smooth paths that will never interfere with one another, which allows for maximum velocity and can produce higher force levels.

EXAIR had a customer needing help applying icing on snack cakes. As baked sponge cakes moved down a conveyor, a continuous ribbon of icing was applied to the individual cakes. Trying to make a clean break in the icing was next to impossible. Mechanical blades needed constant cleaning. Compressed air through a series of holes in drilled pipe used too much air, was noisy and did not make a clean break.

The solution was using an EXAIR Stainless Steel Super Air Knife. A photo eye detected space between cakes turning the compressed air on at the precise moment to apply a uniform airflow and velocity against the ribbon of icing, creating a nice clean break. The stainless steel Air Knife was the best choice for this application. Since there was no contact with the icing, no additional cleaning was required. The Laminar flow of the Super Air Knife had uniform velocity across the entire length and broke the ribbon of icing evenly. This successful result would never have been possible with turbulent air from drilled pipe, nozzles or a blower.

The Super Air knives are just one of many of EXAIR’s Intelligent Compressed Air products. When planning your next project that requires compressed air please contact one of our many Application Engineers for assistance. EXAIR takes pride in our products and customer service.

Decibel Levels in Manufacturing

The Decibel (dB) is a unit used to measure the intensity of sound. Decibel levels are a little tricky as human ears are incredibly sensitive. Our ears can hear everything from a gnat flying by your ear to to very loud jet engines. The range of sound level is very vast. Manufacturing environments can be loud and expose employees to harmful noise levels. You can see some interesting manufacturing noise exposure data from the CDC, here.

On the decibel scale, the smallest audible sound (near total silence) is 0 dB. A sound 10 times more powerful is 10 dB. A sound 100 times more powerful than near total silence is 20 dB. A sound 1,000 times more powerful than near total silence is 30 dB. Here are some common sounds and their decibel ratings:

Experience tells us that many things distance affects the intensity of sound. Noise levels can be due to product design, proximity to the noise, frequency of processes, quantity of noise producing machines or processes. Exposure to high noise levels can be harmful. Extended length of exposure to sound levels above above 80 dB can begin hearing loss. If you feel you have to raise the level of your voice to be heard then you can assume that you are in an environment of 85 or greater dB. OSHA Standard 29 CFR-1910.95 (a) shows the Maximum Allowable Noise Exposure.

EXAIR engineers our products with safety and exposure in mind and we manufacture most every product to be under any threshold where hearing protection is required. If any product (like our largest Super Air Nozzles) is above the threshold, EXAIR is clear that hearing protection is needed. Please visit www.EXAIR.com and view how our Intelligent Compressed Air Products can help your quality of work atmosphere. If you have any questions regarding our products or for advice as to what products can improve the safety of your work environment, please contact any one of our Application Engineers.
