Air Nozzles and Air Jets: An Overview

One of the simplest solutions to lower your air consumption and noise level when it comes to compressed air is to switch your open tubes or pipes and liquid nozzles which are being used for air applications to an engineered compressed air nozzle. EXAIR’s Engineered Air Nozzles and Jets provide a simple solution for a wide variety blow off and compressed air applications and can solve a multitude of process problems efficiently. These applications can include simple blow offs, cooling, part ejection, and much more.

Super Air Nozzles:
Super Air Nozzles are one of the more versatile of all of EXAIR’s Engineered Air Nozzles. They come in many different sizes from a tiny size of M4 threads and 13 millimeters long to the largest with  1-1/4 NPT threads which has a 2″ hex and is almost 5″ long. These are usually used for standard blow off applications that replace open pipes to reduce your air consumption and noise. The force values vary from 2 ounces to 23 pounds of force. 

Another variation of the Super Air Nozzles is the Flat Super Air Nozzles; these nozzles create a small flat curtain of air at a high force to provide a wider blow off area for smaller NPT sized nozzles. The 1” and 2” Flat Super Air Nozzle also have replaceable shims that allow you to adjust the force coming out of the nozzle by increasing the amount of air that is used.

Back Blow Air Nozzles:
Back Blow Air Nozzles are designed in a way that blows that makes it easy to blow out the inside of pipes. The Back Blow Air Nozzles have holes around the outside diameter pointed back that creates a cone of air around the air inlet port. This makes it easy to dislodge clogs in pipes that you don’t want going back into the machine and for blowing out liquid and debris from the inside. They are also commonly used with EXAIR’s Chip Shield as to prevent any particles from flying back and hitting the user. Back Blow Air Nozzles come in three sizes: M4, ¼”, and 1” and can be used on inside diameters ranging from ¼” to 16”.

Super Air Nozzle Clusters:
Super Air Nozzle Clusters use a number of the ¼” Super Air Nozzles to create one nozzle that has a wider cone and larger force. Clusters are usually used in wide area blow off but can also be used for part cooling and part reject as they do supply a wider area of force. Super Air Nozzle Clusters are sized by the number of nozzles in the cluster; the three sizes that we offer are 4-nozzle cluster (3/8” NPT inlet), 7-nozzle cluster (1/2” NPT inlet), and the 12-nozzle cluster (1” NPT inlet).

Air Jets:
Air Jets amplify the total volume of air into a high velocity stream of air. This makes it very useful for blowing off/drying applications and cooling applications due to the higher volume of air flowing through the unit. Air Jets come in two variations which are the High Velocity Air Jet and the Adjustable Air Jets. The High Velocity Air Jet uses a 0.015” shim that allows the air to escape the unit at a high velocity laminar flow to entrain the surrounding ambient air; this can be adjusted down using the shim kit which includes a 0.006” and 0.009” shims. The Adjustable Air Jet allows the user to easily adjust the air gap using the micrometer gap indicator.

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. Give us call at 800.903.9247 and ask for any of our qualified Application Engineers to help you.

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.
