Because they might be needed in some pretty aggressive environments, EXAIR offers many of our Intelligent Compressed Air Products in a variety of materials. One particular material of construction, however, has two distinct benefits. PEEK (Polyether Ether Ketone, for those of us who ruined the grading curve in CHEM102) plastic offers not only superior chemical corrosion resistance; it’s also non-marring. Since EXAIR introduced the first PEEK Super Air Nozzle in 2005, they’ve been specified all over the world; sometimes for their corrosion resistance; other times so they won’t mar or scratch sensitive surfaces…and every once in a while, for both.
I recently had the pleasure of discussing blow off applications with the production manager of a large anodizing & plating company. The chemicals used in these processes are extremely corrosive, and the equipment used in those areas has to be made of something that’ll handle it. PEEK plastic is just such a material. Also, once they’ve treated their customers’ parts, they need to handle them with care…they’re getting paid a premium to provide nice, shiny parts with a perfect finish. When they’re blowing them off, they need to use something that won’t scratch up the surface if the operator makes incidental contact with the blow off tip. Again, PEEK plastic is just such a material. Since their existing blow offs were fitted to 1/8 NPT connections, they chose the Model 1102-PEEK Mini Super Air Nozzle.
Die Cutting is a highly efficient means to produce large volumes of uniquely shaped parts while creating a low volume of wasted materials. There are several different ways to produce die cut parts with one of the more common being Rotary Die Cutting. A Rotary Die Cutter typically incorporates the material passing between a roller die cutter and a heavy roller anvil to cut the specific shape then passes the material down a conveyor or feed line while retrieving the waste material in another collection device.
I recently worked with a customer who was starting to see a large volume of scrap in their vinyl and rubber parts die cutting process as the die cut parts themselves were getting stuck onto the rolling die cutter and weren’t getting grabbed by the conveyor rollers. To try and get the parts to eject from the cutter they installed a few 1/4″ open copper tube air lines running across the roller but were concerned with amount of air they were wasting and the high pitch noise levels of close to 100 dBA. They were also seeing some damage to the parts they were able to get loosened from the die as some of the parts would make contact with the pipe, causing a “blemish” on the part, ultimately failing inspection.
I recommend the customer use our Model # 1100-PEEK Super Air Nozzle. The Model # 1100 consumes only 14 SCFM of compressed air (at 80 PSIG), much less than a 1/4″ open pipe, tested at close to 140 SCFM @ 80 PSIG. This nozzle produces a low sound level of only 74 dBA falling well within the allowable noise exposure levels set forth by OSHA. In addition, the PEEK plastic construction provides a non-marring solution in the event one of the parts did make contact with the nozzle.
EXAIR offers a large selection of engineered air nozzles with varying airflow patterns, force, sound levels and materials of construction to meet a wide variety of application requirements. With help selecting the best solution or to discuss your particular application, please give us a call.
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.
Having an almost 4 year old and an 18 month old at home means I spend at least 15 minutes every evening playing some form of Peek-A-Boo. Last night it was my oldest holding a blanket in front of her while her younger sister sat on the floor and watched. Then she would drop the blanket on the ground and yell PEEKABOO! I’m sure we all know this as the normal version of the game. However, my oldest also easily confuses Peek-A-Boo with hide and seek as well as just flat out scaring people. (Which is hilarious until it happens to you.)
Here at EXAIR we use a different form of PEEK. In fact, we just released another Super Air Nozzle in PEEK plastic. The model 1104-PEEK Super Air Nozzle. This nozzle will tout the same performance as the Zinc/Aluminum and Stainless Steel models but will be better suited for certain applications. Why might someone use a PEEK nozzle instead of a metal one?
The brief list below is just a few of the advantages.
So if you have an application where you need something a little different than metal, don’t forget we offer many of our Super Air Nozzles in PEEK plastic.
