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.
