PEEK Super Air Nozzles Resist Corrosion; Won’t Scratch Sensitive Surfaces

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.

EXAIR’s PEEK Super Air Nozzles can be mounted in place or on a Safety Air Gun, depending on your needs.

Corrosion resistant and non-marring…EXAIR offers our PEEK Super Air Nozzles in six sizes, from the Atto (M4x0.5 threads; 2.5 SCFM; 2 oz force applied) to our High Force Model 1104-PEEK (3/8 NPT threads; 35 SCFM; 1.9 lbs force applied) for an incredibly diverse range of applications.

If you’d like to discuss what material(s) of construction your application(s) require, give me a call.

Model 1109-PEEK Solves Customer Dilemma

1109-PEEK
1109-PEEK Nozzle used in non-marring blowoff application

In a recent application for a new installation, an end user of EXAIR products needed a way to remove defective material from a production line.  At times, the defective items would fall along a conveyor, and the end user wanted to install an effective, efficient blowoff system to address multiple points along the conveyor.  Further to the complexity of the application, the end user needed a product that would not damage the product any further, as they reworked those items to reduce total scrap rates.

Initially, we considered a series of PVDF Super Air Knives, one of which could be triggered “ON” when material was detected.  But, the material size is relatively small, leading to the installation of many, many small Super Air Knives.  This solution was viable from a performance perspective, but further review found a more economic solution.

We then considered Super Air Nozzles.  Perhaps a series of small, efficient nozzles, controlled in groups of (5) or (10), could provide the desired blowoff force.  But, what about the need to not damage the product if in contact with the blowoff device?

This is where the PEEK plastic, model 1109-PEEK, became a perfect fit.  A series of 1109-PEEK nozzles provided the necessary blow off force, consumed minimal compressed air, and provided a non-damaging, non-marring solution.  When controlled in clustered groups, the specific section of the conveyor could be cleared of the defective material, blown into bins for reworking.

These attributes of the 1109-PEEK nozzle, along with high chemical resistivity, and a high temperature range (up to 160°C / 320°F) make it a viable choice for a variety of applications.  Maybe that’s why it is currently nominated for a Plant Engineering Product of the Year Award in the Compressed Air category – Please VOTE for the Precision Air Nozzle here.

EXAIR Application Engineers are well versed in the parameters of our products and a wide range of industrial applications.  If you have a need for engineering support in your application, contact an EXAIR Application Engineer.
