Application Assistance Worksheet for Static Eliminating Blowoff

A few weeks ago I received an Application Assistance Worksheet from a customer.  This customer produces rolls of Teflon tape that are cut to length then sent to an operator to blow them off and place them into antistatic bags for shipment. They were having issues with the tape collecting particles while being conveyed and also while they are waiting to be packaged.  He included the following pictures with the worksheet.


The customer had noted on the worksheet that they had both static and mechanical adhesion of particles from the cutting operation to the finished rolls of tape.  Their current process was to have an operator remove each roll of tape by hand from this bin then use an everyday blow off gun to remove all the particles.   Set the air gun down then have to open an antistatic bag and package the roll of tape.  The issue was the particles were getting blown into the air and then coming back to the surface of the tape because of the static charge, along with the operator found it cumbersome to hold the air gun with one hand while trying to blow off the roll of tape and effectively blow off the entire roll. 

The solution for this is to provide a static eliminating blow off station for the operator to use in order to complete the task both easier and more efficient.  I suggested the customer use a Super Ion Air Knife with a Universal Mounting System to mount it on the operator station and a Foot Pedal to turn the air on and off.  This is going to allow the operator to use both hands to handle the roll of tape and pass it under the laminar flow of air from the knife and simply flip it over to cover the underside.  Then he can place the Roll of tape straight into the bag.  He will not be constantly picking up and setting down an air gun and also will take less time to blow off the roll because he simply has to swipe the roll of tape through the stream once on each face of the tape to blow all particles and eliminate all the static from the roll. 

This is one of many applications that have been simplified or improved as the result of our Application Assistance Worksheet.  Here at EXAIR we try to offer every avenue possible for you, the customer, to contact us with your compressed air problem areas.
