These Nozzles Clean Blind Holes, Pipe Inside Diameters, Tube, Channels and More

EXAIR manufactures a variety of Air Nozzles and Jets . Back Blow Air Nozzles can help reduce cost, clean hard to get to areas in small diameters, pipes, tubes, channels and holes. These nozzles are designed to remove debris from pipes, blind holes, and other areas where it is difficult be effective. Sometimes it is a bad idea to blow debris all the way through a pipe because there may be personnel on the other end or it is simply too long or it may be sealed on an end. 

The Model 1006SS cleans metal shavings from inside a pipe.

The Back Blow Air Nozzles are all made from 316 Stainless Steel with three sizes as outlined below:

Model 1004SS: This is a M4 x 0.5 and delivers the smallest, most effective airflow for cleaning out small diameter tubes, pipes, channels or holes for diameters between 1/4″ up to 1″. Extension pipes available from 6″ up to 36″ in length.

Model 1006SS: The 1/4 NPT Back Blow Nozzle recommended for a wide range of diameters from 7/8″ up too 4″. Extension pipes available from 12″ up to 72″ in length.

Model 1008SS: 1 NPT female and the largest Back Blow Nozzle in stock for diameters from 2″ up to 16″ with pip extensions available from 12″ up to 72″ long.

Model 1306SS-6-CS Heavy Duty Safety Air Gun with 6″ extension and chip shield

These nozzles can also be assembled to our VariBlast, Soft Grip, Heavy Duty and Super Blast Safety Air Guns. EXAIR safety air gun options include chip shields and pipe extensions up to 72″ long. EXAIR has the products and accessories you need to make any job more efficient saving you time and money.

Nozzles for Cleaning Inside Hose, Tube, Pipe and More

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).

Various Views of the Model 1006SS Back Blow Nozzle

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!

1004SS Back Blow Air Nozzle Clean Inside Small Diameters

Model: 1004SS

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.

Back Blow Air Nozzle Family

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.

Model: 1604SS-12-CS

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.

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.

Unique Nozzle Application Eliminates Procedure for Tobacco Processing Facility

1006ss_3up_500

I recently worked on a unique application for EXAIR’s Back Blow Nozzle. Generally, these products are used to clean out chips, debris, and coolant from the ID of pipes or tubes. With (3) different sizes available to clean out IDs ranging from ¼”-16” it’s the ideal solution for cleaning out pipes where blowing forward into the pipe won’t work. They’re also available on the end of a Safety Air Gun with extensions up to 72” long, allowing you to get to hard to reach areas.

This particular application, however, was slightly different. The customer has a large machine that rotates a large drum to dry the tobacco, much like a standard clothes dryer. Inside of this drum is a “spray boom” with an angled top designed to prevent the tobacco from settling and sticking in large quantities. At the end of this “spray boom” are Atomizing Nozzles used to apply a cleaning solution after each drying process is completed at the end of the shift.  Unfortunately, the angled design didn’t work quite as well as they’d intended.

The customer needed a solution that could periodically clean off the boom while the drying was in operation. It wasn’t reasonable to do this at the end of the drying process once the majority of material had passed through. The accumulated tobacco on the boom was perfectly usable product and anything stuck after the cleaning operation would have to be thrown out as waste. In order to clean the boom and allow the stuck tobacco to remain as usable product, we needed an automated solution.

The customer installed (4) of the 1006SS Back Blow Nozzles situated around the boom to remove any stuck-on product during the drying process. The results spoke for themselves, at 90 PSIG it removed a 14” wide radius of material from the surface. By implementing the Back Blow Nozzle they were able to reduce waste and eliminate a daily 1-hour long cleaning process to remove stuck on material from the boom.

Just because it’s an outside-the-box application for one of our products, doesn’t mean it won’t work!! With EXAIR’s Unconditional 30-Day Guarantee, you can test any of our stock products out before committing to keep them.
