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. Reach out to an Application Engineer today if you have a unique application you’d like to discuss!

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.

1006SS – 1/4″ Back Blow Air Nozzle

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.

If you would like to discuss any compressed air application, please feel free to contact an Application Engineer.  We will gladly help you determine which EXAIR product may be right for your application.
