Back Blow Air Nozzles Clean Inside Aluminum Extrusions

A manufacturing plant was using extruded aluminum structural framing for making benches.  After the aluminum parts were cut, they had coolant and chips inside the tube.  They tried to run a rag through the center to remove the material, but it wasn’t able to get into all the crevices and before long the rag was saturated.  Also, they noticed that the chips would scratch the internal surfaces.  For this company, quality was very important to represent their brand.  So, they were needing a non-contact way to clean the inside of these parts after sawing.   They contacted EXAIR as we share the same business facets of first-class customer service and great quality.

Back Blow Air Nozzle Family

At EXAIR, we design and manufacture nozzles for just this type of operation; the Back Blow Air Nozzles.  We offer three different sizes to fit inside a wide variety of diameters from ¼” (6.3mm) to 16” (406mm).  They are designed to clean tubing, pipes, hoses, channels, and extruded “odd” shapes.  The 360o rear airflow pattern can “wipe” without touching the internal surface to remove coolant and chips.  For the application above, I recommended the model 1006SS Back Blow Air Nozzle to fit inside the 1 ½” (38mm) opening.  The range for this Back Blow Air Nozzle is from 7/8” (22mm) to 4” (102mm) diameters.  This 316SS robust nozzle would last a long time without having to change or replace cloth rags.

After installing the model 1006SS onto an extension pipe, the cleaning operation became very easy and efficient.  After each cut, they would run the Back Blow Nozzle through the center with only one pass to clean.  The non-contact wiping removed the coolant and chips without marring the internal surface.  In addition, they were able to speed up their operation by 20%.  Cleaner tubes, less time, cost savings; they were happy that they contacted EXAIR for our expertise.

Model 1204SS-6-CS and 1206SS-6-CS

If you need to clean the inside of tubes, hoses, pipes, etc., EXAIR has the perfect nozzle for you, the Back Blow Air Nozzles.  EXAIR can also offer these nozzles on our VariBlast, Soft Grip, and Heavy Duty Air Guns for manual operations.  They come with Chip Shields and extensions that can reach as far as 72” (1829mm).  Or like the customer above, automate the system to get a great non-contact cleaning.  If you require any more details, you can contact an Application Engineer at EXAIR.  We will be happy to help you.

EXAIR Back Blow Nozzle: An Overview

In certain applications such as blowing chips or debris out of a pipe or blind hole, it may not be possible to blow forward. The pipe may be too long, making it impossible to push the debris all the way down the pipe or the other end of the pipe may not be open. In either of these scenarios, the Back Blow Nozzle is the right tool for the job. An array of holes around the diameter of the Back Blow Nozzles provides a powerful 360° airflow pattern that will clear out any leftover coolant or chips from the machining process.

Small 1004SS easily clears debris

EXAIR has three different size Back Blow Nozzles; the 1004SS (M4 x .5), the 1006SS (1/4 NPT), and the 1008SS (1” NPT). The 1004SS is recommended for use on pipes as small as ¼” and up to 1”. The 1006SS can be used for a wide range of pipe sizes, from 7/8” up to 4”. The 1008SS nozzle offers the greatest overall force for stubborn or sticky materials stuck to the inside diameter of the pipe. This nozzle is suitable for use in pipes ranging from 2”-16”. As the Back Blow Nozzle will be blowing chips and debris back out of the pipe towards the operator, it is always recommended that a Chip Shield is used. The strong polycarbonate Chip Shield will keep them safe from flying debris and keep you in compliance with OSHA directive 1910.242(b). For visual representation of the performance of the Back Blow Nozzle, take a look at this short video clip that demonstrates its use.

All of EXAIR’s Back Blow Nozzles are available with extensions. For the 1004SS we have extensions from 6”-36”, and from 12”-72” for the 1006SS and 1008SS. The Back Blow Nozzle can also be installed on our VariBlast, Soft Grip, Heavy Duty, and Super Blast Safety Air Guns. With such a wide range of available sizes and configurations, we can tackle just about any internal pipe cleaning application. If you have a process in your facility that may benefit from the use of one of these nozzles, give us a call and get one on order today!

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!
