Back Blow Air Nozzles Clean Inside Diameters

They say time flies when you’re having fun. Maybe that’s why I found it a little hard to believe it’s been almost two years since we introduced the Back Blow Air Nozzles. They’ve become yet another “textbook” solution to a great many applications:

*Model 1004SS M4 Back Blow Air Nozzles are used to dry the inside of a closed cylinder after a zinc bonding process.  They’re also fitted to Model 1204SS-12-CS M4 Back Blow Safety Air Gun to remove chips & cutting fluid from freshly cut pipe ends.

*Our Model 1006SS 1/4 NPT Back Blow Air Nozzle won Plant Engineering Magazine’s “Product Of The Year” Bronze Award in 2015, and are successfully employed in a wide range of uses:

  • Blowing out splined bores by a gear manufacturer
  • Quickly cleaning out spindles between tool changes by a CNC machinery operator
  • Removing the last bits of powder from spent toner cartridges by a printing equipment recycler

*The Model 1008SS 1 NPT Back Blow Air Nozzle is becoming famous in hydraulic cylinder repair shops…after a cylinder bore is honed, one quick pass of the powerful blast it produces cleans bores from 2″ to 16″.  We can even put it on the Model 1219SS Super Blast Back Blow Safety Air Gun, with a 1ft, 3ft, or 6ft extension.

EXAIR Back Blow Air Nozzles come in three sizes, for bores from 1/4″ to 16″ in diameter!

If you want to see how they work, check out this video:

I could have sworn Lee Evans just made that video, but apparently, it’s over a year old now.  Time does indeed fly, and I promise we’re having fun!  If you’d like to find out more about how a Back Blow Air Nozzle – or any of our engineered compressed air products (old or new) – can make your operations quieter, more efficient (and hence, probably, more fun,) give me a call.

3 Keys for Eliminating Static

Everyone is familiar with static electricity. It is the cause of the shocks we feel during the winter time as we shuffle our socks across a carpet. It is also the driving force behind lightning in the sky. Static electricity can be a nuisance at home, but in an industrial setting it can lead to quality issue, material faults, and hazardous sparks. Though most engineers and maintenance technicians know about static electricity not many of the them understand its intricacies, even fewer understand the best ways to mitigate static and still less understand static eliminators, known as ionizers, that can eliminate static without contacting the surface. Here are 3 keys to know about static.

First, static resides on a surface. Though a part may be charged on one surface. The opposite face of the part may be completely unaffected. Here is an example.

Toner Cartridge – Static inside the plastic container attracts toner.

Even though the outside of this container is free of static the inside of the container still attracts toner to the inside surface. In order to blow out the toner from the inside of the cartridge, we needed to use a static eliminator inside the plastic container.

The second key to eliminating static is that either polarity can cause a problem. Static will cause problems if it is different between materials. Whether the charge on a surface is positive or negative doesn’t matter. It is the difference between charges that causes the attractive forces and static shock. EXAIR static eliminators utilize alternating current to create both positive and negative ions to eliminate both positive and negative ions.

The third key to properly eliminating static is that ionized air works best the closer you can be to a product. Because we eliminate both positive and negative ions, EXAIR static eliminators work best when they are blown directly on a surface that needs treated. The further the ionizer is moved from a surface the less effective it will be. EXAIR products without air assistance typically need to remain within two inches of the surface they are treating. Products with air assistance can be much farther away. It is the inlet pressure, the value of the static charge and the speed of the surface (if it is moving) which will dictate how far away an EXAIR static eliminator can be positioned.

Eliminating static is a very specialized application, it revels its self in dry conditions. It can lead to problems with webs, rollers, and idlers. If you need help with your static problem, please contact an application engineer.
