PVDF Super Air Knives Resist Chemical Exposure

When my sons were little boys, I would find myself looking forward to their teenage years, so they’d be more mature and I’d be able to relate to them better. Those of you with older kids may begin laughing now. My thinking was, I distinctly remember being thirteen. What I failed to recall was just exactly how peculiar I appeared to my parents (and they to me), and now, I’ve got the view from the other side.

In the interest of time and good taste, I’ll limit this discussion to the subject of food. I always liked (and still do like) ketchup almost as much as the french fries. Same for the “fixin’s” on a sandwich. In fact, as an adult, I’ve discovered a universal truth, that bacon or peanut butter can be used to improve the quality of ANY sandwich.

My sons, however, don’t feel this way at all. My fifteen year old won’t put anything but cheese (American cheese, at that) on a hamburger, and his thirteen year old brother won’t even do that. Curiously, the older one prefers cheese pizza, and the younger one will eat anything that used to be an animal on his. And neither one will put any sort of condiment or sauce on ANYTHING they eat. If it’s on their plate, it better not “have stuff on it.”

I was reminded of that phrase this morning during a conversation with a caller about an Air Knife application. It will be operated in the fairly aggressive chemical environment of a plating line. We discussed the chemical compatibilities of our different material offerings, and found that the Model 110006-PVDF 6” Super Air Knife was the one he was looking for. The body & cap are PVDF (Polyvinylidene Fluoride,) the shim is PTFE, and the fasteners are Hastelloy© C-276 alloy. It’s impervious to a long list of acids, caustics, and other harsh chemicals that even the higher grade stainless steels don’t stand a chance with.

PVDF Super Air Knives provide superior corrosion resistance.

Our PVDF Super Air Knives provide the same highly efficient and quiet performance as their aluminum, 303SS, and 316SS counterparts – plus you can get a lot more “stuff” on them without damaging them.

Regardless of where you need to install it, or what kind of stuff you might get on it, EXAIR has a Super Air Knife that will hold up in your application. Give us a call, and we’ll find the right one for you.

Expanding The Family And Our Product Lines

If you follow my blogs and or Twitter you may know that I am currently the proud father of two wonderful and amazing daughters.   My wife  and I just recently found out that our third child which is due in early December is also a girl.   So I will then be the proud father of three beautiful daughters (and the guy with a really nice shotgun that holds multiple rounds). Some may say I’m overprotective – I’ll just have to agree.

All of our friends continually ask me if I am upset that I didn’t get a son, my truthful response is, “No.”  I am rather pleased to have all three girls for right now.   The fact is, the oldest and now middle daughter are both already working in the garage with me, constantly wanting to do whatever it is I am doing, and they are a blast to be around.   Since they are all three girls I don’t have to worry about giving them that awkward adolescent discussion (I would give that to any boys we may have), and I get to scare whoever tries to come and date any of them when they turn 21 or 25, perhaps 30.

EXAIR is also expanding its family.  We have welcomed a wonderful little PEEK nozzle to our already large Super Air Nozzle product family.   This one comes in with M5 x 0.5 threads, or with a 1/8th” NPT adapter.  The nozzle can produce 5 ozs. of force while using only 4.9 SCFM of compressed air at 80 psig inlet pressure.   The PEEK plastic construction gives it excellent ratings for chemical resistance and temperature resistance while also being non-marring. PEEK thermoplastic fits well into the plating industries, metal etching, pickling lines, sea water environments because it outperforms the 316SS material of our other nozzles when in those environments. The maximum temperature rating for this nozzle is 320F.

The picture above shows the nozzle removing excess plating solution which takes advantage of the chemical resistance for nickel plating, as well as the non marring in case of contact with the part.

The wonderful and wacky Professor Penurious has named this little nozzle as our Pico Super Air Nozzle.

If you have an application that needs good chemical resistance, or just an upgrade to save compressed air, contact us.
