EXAIR Helping the Medical & Pharmaceutical Industries

EXAIR designs, manufactures, sells and supports many Intelligent Compressed Air® products influencing many industries round the world. I have personally talked to many manufacturing companies needing our products and want to focus on just a few applications that I helped within the medical industry.

Air Knives: Our Air Knives are very versatile and generally used to cool, dry, and clean products and processes. The most recent application I had using our Super Air Knives in the medical field was using a compilation of knives strategically arranged to blow moisture off stainless steel tubes which are components af a larger medical product.

Cold Gun: Our customer in the pharmaceutical industry was experiencing downtime and low efficiency rates as the tablet punch presses for their pill manufacturing lines were heating up and causing downtime. The solution was placing a couple Cold Guns blowing cold air on to the punch presses to remove the heat. The end result was higher efficiency rate and little to no downtime from the punch presses over heating.

Intellistat Ion Air Nozzle: The Intellistat Ion Air Nozzle has been used in clean room applications. These have been used most commonly to keep contaminants away from packaging and labeling areas. The Intellistat Ion Air Nozzle has a clean room classification: ISO 14644-1 Class 5, operational.

These are just a few examples how EXAIR helps in the medical industry. If you have questions or want to discuss a specific application and need help determining the best EXAIR product for you, please contact any of Applications Engineers as we are ready to help.

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.

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.
