Create a Custom Blowoff Solution With EXAIR’s Industry-Leading Super Air Knives

Published on by Tyler DanielLeave a comment

EXAIR’s Super Air Knife utilizes a source of compressed air to create a laminar sheet of high velocity air. This supplied compressed air mixes with ambient air that is entrained into the primary airstream. The Super Air Knife entrains ambient air at a rate of 40:1, making it VERY effective in a variety of drying, cleaning, and cooling applications. Available in lengths ranging from 3”-108” and in a variety of different materials of construction, there’s a Super Air Knife available for just about any application. Any time you have product moving along a conveyor that needs to be cleaned, dried, or cooled off, a Super Air Knife is the ideal fit.

The Super Air Knife is available in aluminum, Type 303 & Type 316 stainless steel, as well as in PVDF with Hastelloy bolts for extremely corrosive applications.  While there are numerous options available off the shelf ready to ship same day, not all applications can be served by a stock option. Since EXAIR handles all the manufacturing of these products in our facility in Cincinnati, Ohio, we have a great deal of control over the manufacturing process. If your application cannot accept something right off the shelf, we’re constantly producing special customized knives to fit most requirements.

Our knives can be manufactured in a special length if a stock length won’t fit in your application. We’ll use the same design and size profile and can build it to the precise length you require in order to fit perfectly onto your machine. If the dimensional profile of an existing knife isn’t suitable, we can change that too! The Super Air Knife shown below utilizes a very thin design and has been completely modified to achieve the smallest overall profile possible.

All Super Air Knives come stock with ¼ NPT air inlets and ¼-20 tapped holes along the bottom that can be used for mounting. Unfortunately, that isn’t always going to work for every application, so we also manufacture specials with custom air inlets as well as additional mounting holes to fit right onto any custom bracket. The photo below shows a modified stainless steel Super Air Knife with additional mounting holes machined onto either end.

We don’t just offer them in different shapes and sizes as a special, but we’ve also manufactured stock length knives out of entirely different materials. Shown below are two knives of different materials that aren’t already on the shelf. On the left-hand side is a knife manufactured from PVDF and on the right a glass filled PEEK material with brass hardware and a PTFE shim. In this application, the customer was noticing ground interference due to the aluminum knife construction. They specified this particular material, and we were able to machine a knife completely customized for this application.

Every year a new request comes across that is something we haven’t done before. Just because you don’t see it in the catalog doesn’t mean it isn’t possible when you deal with EXAIR. We’re here to make sure you get the most out of our products, and sometimes that isn’t possible right off the shelf. Contact an Application Engineer today if you’d like to discuss your application and begin the process of identifying your next custom solution!

EXAIR Products “Built to Last”

Published on by EricKuhnash@EXAIR.comLeave a comment

When I hear “Built to Last” ads come to mind such as Ford Trucks and Craftsman tools. Advertising promoting product integrity will always get my attention. Although I have not owned a Ford truck, I have many friends that have and swear by them, so I’m thinking my next truck might be a Ford. I have owned a lot of Craftsman tools and put them through rigorous use and I never had to use the “Lifetime Warranty“. They were designed and built to last and this is how EXAIR designs and manufactures their Intelligent Compressed Air Tooling.

EXAIR Design and Engineering team designs our items with performance and repeat manufacture ability in mind. EXAIR products have no moving parts so very little maintenance is required. As long as a source of clean dry compressed air is supplied to the product and following our recommended Installation instructions not much can go wrong,

EXAIR has a “5 Year Built to Last” Warranty against defects in workmanship and materials on all compressed air products. This warranty applies under conditions of normal use, but does not apply to defects that result from intentional damage, negligence, unreasonable use, wear or exposure. An example of a non warranty situation would be using an abrasive material such as sand with our Aluminum Line Vacs. The abrasive nature of the sand will wear the aluminum Line Vac out well before the 5 years. Our application engineers will discuss your application and recommend products that fit your project and our 5 Year Built to Last Warranty.

EXAIR also has a 30-Day Guarantee that allows you to make a purchase and run trials to see the effectiveness of our product and how they meet your expectations. If the item provides desired results then great we are both happy but if you do not see the desired results then you have 30 Days from purchase to return the product. An Application Engineer can discuss your findings and issue a “Return Authorization” if needed. You will receive a full credit without any restocking fees.

EXAIR has confidence in our products to last and perform standing behind our products. Our confidence is why we offer both 5 Year Built to Last Warranty and the 30-Day Unconditional Guarantee. If you have any questions as to what EXAIR product will provide the best result for your application, please contact one of our qualified Application Engineers, so we can review this with you and make the best recommendation for your project(s).

EXAIR has Intelligent Compressed Air® Tooling

Published on by EricKuhnash@EXAIR.comLeave a comment

I used to work for a plastic injection molding facility that also had several different types of secondary added value processes. We used compressed air in our paint rooms, assembly areas, molding room and other various processes. I don’t recall what our compressed air usage was as we had 7 total manufacturing facilities in 5 different states. I tracked our electric bills, phone bills, water bills and all of our vending billing but, I never took the time to realize the importance and cost of compressed air.

I was successful in cost reduction activity in all those ares and so proud of the accomplishments but not once did I take the time to realize what I could save with our compressed air systems and the tooling we used with compressed air. The illustration below shows what can be saved when looking at just one air nozzle:

Compressed Air Savings

This is just one air nozzle. We used about 100 Air Nozzles, 20 paint nozzles, 50 Line Vacs and other various compressed air products. If I was able to calculate savings for all the products we used and focused on fixing air leaks in the system I would have been a real hero. Well guess what? EXAIR can help you calculate and determine the best products to help you generate these savings. We can even help you calculate your savings.

The other benefits included with EXAIR Intelligent Compressed Air® products will be the noticeable noise reduction and compliance with OSHA Standards 29 CFR-1910.95(a) Maximum Allowable Noise Exposure and 29 CFR-1910.242(b) Harmful Dead End Pressure. EXAIR meets or exceeds these OSHA Standards providing you with a peace of mind for conformance.

EXAIR has a great catalog showing our products, capabilities and performance information. Our website www.EXAIR.com offers catalog information, prices, performance, drawings, videos, blogs, air savings calculator and much more information. If you are unable to find what you need you can conveniently call one of our Application Engineers for assistance.

Are you looking for a reliable heavy-duty vacuum system? Are you tired of your electric motors failing? EXAIR has a pneumatic Heavy Duty Dry Vac that is engineered with the power to vacuum heavy materials, The Heavy Duty Dry Vac is constructed from a hardened alloy that resists abrasion from the harshest of debris, like garnet, glass, tumbling media and steel shot. This system has no moving parts which means no motors or bearings that can fail on you.

The Heavy Duty Dry Vac requires only 68 SCFM at 80 psig of compressed air to operate. Using a hardened alloy construction for the vacuum generator gives the system an increased resistance to abrasive material including sand and blasting material. Depending on your application and the volume of material you need to vacuum we provide 3 different sizes, 30-gal, 55-gal, and 110-gal.  

Our Heavy Duty Dry Vac is the perfect solution for cleaning dry media such as abrasive media, sand blasting, absorbents and gravel from your shop floors and work surfaces. The possibility of electric shock you experience with electric motors is virtually eliminated as the source of power is compressed air. The use of an anti-static hose also prevents shocks when vacuuming dry materials.

EXAIR Heavy Duty Dry Vac Family

EXAIR‘s Heavy Duty Dry Vacs come in 30, 55 and 110 gallon options with several accessories available to help your cleanup and specific needs. These are stock items and can generally be shipped the same day with orders received before 2:00 PM EST. If you have questions regarding our Heady Duty Dry Vac or any of our Industrial Housekeeping Products please give us a call.
