Some 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.
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).
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!
A metal fabricator made stainless steel tubes with a ½” (13mm) inner diameter. Their process started by cutting the tubes into 8” (203mm) lengths. The tubes would go through a wash system, then to a honing machine. Once the inner diameter was honed to the specific diameter and concentricity, the tubes would be washed again for packaging. The honing machine used oil to accurately grind the inner diameter. Since oil and water does not mix, they had to dry the I.D. before honing. They contacted EXAIR to see if we could find a solution.
For cleaning the I.D. of parts, EXAIR manufactures three different sizes of Back Blow Air Nozzles that are designed to clean inside tubing, pipes, hoses, and channels. They can range from internal diameters from ¼” (6.3mm) up to 16” (406mm). The 360o rear airflow pattern can “wipe” the entire internal surface without contacting the surface to remove water, coolant, chips, and debris. In reviewing the inner diameter above, I was able to recommend a model 1004SS Back Blow Air Nozzle. This 316SS robust designed nozzle can fit inside and clean tubes with internal dimensions ranging from ¼” (6.3mm) to 1” (25mm); perfect for the ½” (13mm) diameter tube.
The customer indicated to me that there was a rush to start this project. EXAIR stocks thousands of cataloged items for same day shipping. He asked if EXAIR had any other components to help them to expedite their drying process. Well, of course we do! Since the tube was 8” (203mm) long, EXAIR has extension tubes that are used with our VariBlast Compact Back Blow Safety Air Gun. We have them ranging from 6” (152mm) to 72” (1829mm) in incremental lengths. For this customer, I recommended the 12” (305mm) extension to reach through the tube. And, since it was a manual operation, I also recommended the model 9040 Foot Valve.
Their operator could place the tube over the model 1004SS Back Blow Nozzle and with the Foot Valve, turn on the compressed air to dry the tubes. With the powerful air stream, the entire internal surface was dry for the honing process to follow.
If you need to clean the inside of tubes, hoses, pipes, etc., EXAIR has the perfect nozzles for you, the Back Blow Air Nozzles. EXAIR can attach these nozzles to our VariBlast Compact, Soft Grip and Heavy Duty Safety Air Guns for easy-to-use operations. For this customer above, they were able to use components to get the operation running the next day. If you need more information, you can share your application with an Application Engineer at EXAIR. We will be happy to help.
EXAIR manufactures three different sizes of Back Blow Air Nozzles to clean inside tubing, pipes, hoses, and channels. The 360o rear airflow pattern can “wipe” the entire internal surface clean from coolant, chips, and debris. They are constructed of 316SS, making these nozzles robust and durable.
Our smallest Back Blow Nozzle is the Model 1004SS. It has a M4 X 0.5 male thread and can clean diameters ranging from ¼” (6.3mm) to 1” (25.4mm).

It has a 1” NPT connection, and it can be used inside diameters ranging from 2” (51mm) to 16” (406mm).
Now, what can make these unique types of air nozzles even more useful? Attaching them to an EXAIR Safety Air Gun. In this blog, I will go through each of our Back Blow Safety Air Guns that EXAIR can offer from stock.
The unique feature that sets the VariBlast apart from other small air guns is the force variability. The valve is designed to control the opening to allow for a variable force with the same nozzle. The VariBlast is made from a durable cast aluminum construction for tough industrial use. It has a rugged ergonomic grip with a user-friendly trigger. The compressed air inlets are located in two different positions to select the best fit for your application.
With the model 1004SS Back Blow nozzle, the VariBlast Compact Back Blow Safety Air Gun is a small but powerful tool that can clean inside smaller pipes, tubes, and hoses. They come standard with extension tubes and a Chip Shield. The extension tubes range from 6” (152mm) to 36” (914mm) to extend deep inside cavities and openings. The Chip Shield is made from a durable polycarbonate material that will protect your operators during use.
The next air gun in this series is the Soft Grip Safety Air Gun. With an ergonomic soft handle and full-grip trigger, the Soft Grip Safety Air Gun can be used for hours without fatigue. EXAIR offers two types of Back Blow Nozzles with the Soft Grip; model 1004SS and model 1006SS.
As a “bigger cousin” to the VariBlast above, the Soft Grip Back Blow Safety Air Gun with the model 1004SS has extensions ranging from 6” (152mm) to 36” (914mm) as well as a Chip Shield. The Soft Grip with the model 1006SS Back Blow Nozzle has extensions that range from 6” (152mm) to 72” (1,829mm) in length with a Chip Shield. Both of these types of Soft Grip Back Blow Safety Air Guns are great products in allowing you to clean inside a greater variety of diameters and lengths.
For rough industrial environments, EXAIR offers the Heavy Duty Safety Air Guns. They come with a composite rubber grip and a wide curved trigger. It has a 3/8” NPT inlet for increased compressed air flow for those “tough” cleanings.
The Heavy Duty Back Blow Safety Air Gun comes standard with the model 1006SS Back Blow Nozzle, an extension pipe, and a Chip Shield. The extensions lengths can range from 6” (152mm) to 72” (1,829mm). If you need a tough air gun for rugged areas to clean inside pipes and tubes, the Heavy Duty Back Blow Safety Air Gun could be the best candidate for your application.
As our largest model, the Super Blast Back Blow Safety Air Gun has the strongest blowing force. They can clean large areas inside pipes, channels, and tubes ranging from 2” (51mm) to 16” (406mm) in diameter. It has a soft foam grip for easy handling and a spring-loaded manual valve that will turn off if dropped. The model 1008SS Back Blow Nozzle is mounted to an extension that is either 1 foot (0.3m), 3 feet (0.9m), or 6 feet (1.8m) in length. With a 1” NPT inlet, the Super Blast Back Blow Safety Air Gun will generate a strong blast of air for cleaning and removing troublesome material.

A metal fabricator used a cutting machine to cut different sizes and shapes of stainless steel tubing. The process was automated and the machine would cut two tubes at a time. After the cutting operation, the machine would deposit the tubes into a nearby bin. The operator would then stack the tubes in a wooden container as shown above. Before the tubes could be transported to another department, the operator would have to clean the inside of each tube. The current method was to attach a rag to the end of a rod and pushed it inside the tube to remove any coolant and chips that remained from the cutting operation. Of course, the ability to clean thoroughly with a rag is reduced greatly after a short time of use. The cleaning process was very time consuming, and when the rag was not changed in a timely manner it did not clean effectively. The inside of the tubes would get marred from the excess chips that remained on the rag. This would visually affect the surface finish of the stainless steel. They emailed me the application detail as they were looking for a non-contact way to clean the inside of the tubes.
The first question from the customer was if we could customize our air nozzles to clean the different diameters and shapes that they were cutting. EXAIR has made special air nozzles to accommodate unique applications, but I wanted to first make sure that EXAIR did not have a manufactured nozzle in stock to fit this application. I requested the dimensional information, and the customer sent me the sizes and shapes of the tubes that were ran through their cutting machine. (Reference Table 1 below).
EXAIR manufactures three different sizes of Back Blow Air Nozzles that are designed to clean inside tubing, pipes, hoses, and channels. They can range from internal diameters from ¼” (6.3mm) to 16” (406mm). The 360o rear airflow pattern can “wipe” the entire internal surface clean and can remove coolant, chips, and debris. In reviewing the dimensions from Table 1 above, I was able to recommend just one Back Blow Air Nozzle for all the tubes; even the square and rectangular ones. It was model 1006SS Back Blow Air Nozzle. This 316SS robust designed nozzle can fit inside and clean tubes with internal dimensions ranging from 22mm to 102mm, and it was perfect for all of these tubes.
The customer indicated to me that the tubes were all cut to identical lengths at 550 mm (21.7”). Being that this was a manual operation, I suggested the Back Blow Air Nozzle with our Soft Grip Safety Air Gun. This ergonomically designed Safety Air Gun is designed for hours of use without fatigue. In combination with the nozzle, we are able to add extensions and chip shields. With extensions, EXAIR has a range of lengths from 6” (152mm) to 72” (1,829mm). With the designated length above, I recommended the model 1206SS-24-CS which has the Soft Grip Safety Air Gun, the model 1006SS Back Blow Air Nozzle, a 24” (610mm) extension, and a chip shield.
The configuration allowed for the operator to reach through the tube to clean with only a one-time pass. The CS designation is for a chip shield which will protect the operator from any excess debris and coolant. With the model 1206SS-24-CS, the operator could now pick up a tube, use the Soft-Grip Back Blow Safety Air Gun to remove the debris and coolant from within the round tubes, square tubes and rectangle tubes. Also, they did not have to worry about changing the rags when it got dirty. What an amazing purchase for this company, as they increased the speed of the cleaning operation by 70% without affecting the inside finish of the stainless-steel tubes.
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 attach these nozzles on our VariBlast Compact, Soft Grip and Heavy Duty Safety Air Guns for easy-to-use manual operations. For this customer above, they were glad that they contacted EXAIR about their application. If you require more details, you can share your application with an Application Engineer at EXAIR.
