Customize Air Knives Specific to Your Application!

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 of the manufacturing of these products in our sole 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 any requirement.

Any of 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 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 thinnest 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 the 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 top is a knife manufactured from PVC and on the bottom 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.
Each and every year new requests come 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 custom features or materials are necessary to get that accomplished.

Taking Yourself Out Of Your Comfort Zone

During the warmer Ohio weather months, April through October, my blog posts may include information about taking my motorcycle to some road course tracks (and now even a cold month or two).  I take my bike to open track days where (mostly) amateur riders can get on a proper race course. There are people on the track for the first time and people who race professionally.   They will generally divide the riders into several groups, Novice, Intermediate or Advanced.  The control riders/coaches at the track will help you to determine what group you should ride in and then help you throughout the day.   Below is a video of a control rider that is also a professional rider at Mid Ohio Sports Car Course.  (Don’t mind the music, it’s not my cup of tea either.)

For the novice group there are classes after each session, as well as skills practiced in every session.  This is to help teach the beginning track rider that the same habits you use on the street are not meant for the track, as well as how to be as safe as possible while being on the track.  This is the most watched and controlled group due to the fact it generally has the most riders and they are all the newest to the track.

For intermediate group there are optional classes and you just run your own pace.  They step up the skill level by not enforcing you to focus on a skill during each session or requiring you to go to a class after each session of the day.  The pace is considerably faster than novice and the only ways to get instruction are to either ask a control rider for it or if they see something to help you with they will generally stop you and coach you on how to do it better.

The final group is advanced, or race class.  This has the same elements as a professional race minus the grid at start-up.   There aren’t really any passing rules and the control riders are mainly all professional racers or former racers who can still make your head spin as they fly past you.  Similar to the intermediate group the only way you will get help is to ask for it.

For the past two years I have been running in the intermediate group and it is a serious meat grinder.  You will have people in there that are fast enough to be in advanced group, but are too scared.  As well as having people who let their ego and pride tell them they don’t need to learn anything from a novice class and should really be in novice learning as much as they can.  I stayed in Novice for over the first year of track riding that I had done.   Some people choose to never leave the novice group because that is exactly where they are comfortable.  They don’t want to worry about the other classes and are perfectly fine with not even being the fastest person in Novice.  This is perfectly acceptable for some, but I had to push myself out of my comfort zone in order to really enjoy the entire experience.  Even though I have been to the track several times now I am always out of my comfort zone in intermediate because there are always new people showing up and you never know when you will running with a group that should be racing, or a group that should be getting coached in novice.

Here at EXAIR we have customers that could fit into each of these groups also.   The customer who doesn’t know what an engineered solution is and doesn’t understand the cost of compressed air.  The intermediate user who has used some of our products in the past but is encountering new issues and knows that we can help lead them in the right direction.  As well as the advanced users who know exactly what they need and sometimes even request a special unit to fit their exact needs.

No matter the case, we can help as well as coach even the most advanced users of our products on how to use compressed air better.  If you are reading this and you don’t know the difference between a Super Air Nozzle and an open pipe, then give us a call.  We will help teach you the differences as well as make sure you understand the need for engineered solutions on your compressed air system.  It may be out of your comfort zone for the first few calls but we will make sure you get to the level you want to be so you get back into your comfort zone.
