Cleaning Out Pipes, Extrusions and Blind Holes

Look at the picture below of a band saw cutting a piece of tubing.  The amount of debris and coolant that is coating the pipe on the inside diameter and outer diameter is substantial.  Cleaning off the outside of a pipe is fairly easy and straight forward.  Cleaning the ID can be difficult.  This is a single instance where one of the EXAIR Back Blow Air Nozzles can turn a cumbersome job into a quick and easy step in the process.

The tubing in the photo appears to be around a 3 or 4″ ID tubing which makes it ideal to be cleaned out internally by the model 1006SS – 1/4″ Back Blow Air Nozzle.  This nozzle is ideal for passage ways ranging from a 7/8″ diameter up to a 4″ diameter.

While cleaning out the short section may be able to be obtained with a forward blowing Safety Air Gun, if this was being cut from a 20′ length of tube it would be difficult to remove the debris from the remnant section of tubing.  The advantage being the debris from the saw cut no longer has to be blown out or left in the longer lengths of the tube.   The Back Blow Air Nozzle can easily be inserted and remove debris back from the saw cutting end.  Lee Evans demonstrates this in a video below.

Back At Ya!

This may not be big news as it happens almost every month.  EXAIR is continuing to grow our product line and this time it is something we have never done before.  This new EXAIR Engineered Solution doesn’t blow debris away, instead, it all comes back towards you.   Why would you want this you ask?  What does this new-fangled contraption look like?  Both of those questions will be answered below.

To answer the first question, why would you ever want debris to come back at you?  Well, this isn’t for just blowing any part or area out, this nozzle has been designed for a special purpose – to blow out pipes, tubes, extrusions, and even some blind holes or pockets.   This is ideal when working on a piping system that you may need to clean out and don’t want to push debris further into the system.   It is a quick and easy way to clean out chips from a saw cut operation for tubing or extrusion.  The nozzle could even be used to clean out cylinders or crank shaft openings on engine blocks.

So what is the name of this new nozzle and what does it look like?

What does it look like already!
What does it look like already!
