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 Back Blow Air Nozzles are all made from 316 Stainless Steel with three sizes as outlined below:
Model SS: 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 SS: 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 SS: 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.
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. and ask for any of our qualified Application Engineers to help you.

EXAIR uses many different methods to connect with our customers. We have our website, social media, blogs, publications etc. We like to share solutions for some of the most common pneumatic problems in the industry. EXAIR generated a large collection of application information where EXAIR products have already solved problems and improved processes. We organized them by Application and by Industry. In this blog, I will show you how to use our Application database; specifically, for the Automotive Industry.
Compressed Air Systems are considered to be a fourth utility within industries because they use a large amount of energy. Whether an air compressor that uses fuel for portable units or that uses electricity, it is important to use this system as efficiently as possible. This would also apply to the Automotive industry. EXAIR has a library of different processes in which we already improved these areas safely and efficiently. If you are part of the Automotive industry, it could benefit you to take a peek at the areas that we already improved, established OSHA safety, and saved money.
Here is how you can find this library. First, you will have to sign into EXAIR. Click here: Log In. Once you fill in the proper information, you can then retrieve a great amount of resources about EXAIR products that we manufacture. The Application database is under the Knowledge Base tab. (Reference photo below).
At the Application Search Library, we have over one thousand applications that we reference. In the left selection pane, we organized then in alphabetical order under two categories, Application and Industry.
Scroll down in the selection pane until you come to the sub-category: Industry. Under this Sub-category, you will find three selections that are related to this blog: Automation, Automobile Recycling, and Automotive. We have other applications as well that may relate to your specific processes if you scroll up and down the list like; Part Ejection and Machining. You will find many product applications that have already improved processes and solved problems.
Why is this important? If you are a plant manager or owner, the value of the Application Database can improve your current processes with pre-qualified results. Within the Automotive industry, simple solutions can be found to address those “nagging” issues that you see every day. For crisis situations and shutdowns, EXAIR categorized these applications in a way to reference quickly and easily. And since EXAIR has a high volume of stocked items, we can get the parts to you very fast so you can quickly be on your way to a solution.

When a wide area is in need of cleaning, cooling, or drying there isn’t a better option available on the market than EXAIR’s Super Air Knife. It’s laminar and even airflow across the length has solved process problems and provided manufacturing solutions for thousands of customers. We’ve been manufacturing Air Knives for over 30 years now, with the Super Air Knife making its first appearance back in . Since then, the Super Air Knife has undergone a few enhancements over the years as we’re constantly trying to not only introduce new products but also improve on the ones we have. We’ve added new materials, longer single piece knives, as well as additional accessories.
What sets EXAIR’s Super Air Knife above the competition is the ability to maintain a consistent laminar flow across the full length of the knife, particularly when compared against blower operated knives or even fans. A fan “slaps” the air, resulting in a turbulent airflow where the airflow particles are irregular and will interfere with each other. A laminar airflow, by contrast, will maintain smooth paths that will never interfere with one another.
Blower knives are commonly seen in industry that also cannot provide a laminar airflow. Additionally, they are expensive to purchase, produce a high sound level, and require periodic maintenance. Costly maintenance that results to downtime, as well as the physical space the system takes on the shop floor are all eliminated when using the Super Air Knife.
One of the simplest alternatives to the Super Air Knife is a homemade drilled pipe. While it’s quite easy to put together with materials that are likely already available to you, the true hidden cost here is the operating cost. The high energy use related to the total compressed air consumption makes this “seemingly economic” solution into an expensive one quickly. Not to mention, these devices are not considered to be safe per OSHA .242(b).
The effectiveness of a laminar airflow vs turbulent airflow is particularly evident in the case of a cooling application. The chart below shows the time to cool computers to ambient temperatures for an automotive electronics manufacturer. They used a total of (32) 6” axial fans, (16) across the top and (16) across the bottom as the computers traveled along a conveyor. The computers needed to be cooled down before they could begin the testing process. By replacing the fans with just (3) Model Super Air Knives at a pressure of just 40 psig, the fans were cooled from 194°F down to 81° in just 90 seconds. The fans, even after 300 seconds still couldn’t remove enough heat to allow them to test.
Utilizing a laminar airflow is also critical when the airflow is being used to carry static eliminating ions further to the surface. Static charges can be both positive or negative. In order to eliminate them, we need to deliver an ion of the opposite charge to neutralize it. Since opposite charges attract, having a product that produces a laminar airflow to carry the ions makes the net effect much more effective. As you can see from the graphic above showing a turbulent airflow pattern vs a laminar one, a turbulent airflow is going to cause these ions to come into contact with one another. This neutralizes them before they’re even delivered to the surface needing to be treated. With a product such as the Super Ion Air Knife, we’re using a laminar airflow pattern to deliver the positive and negative ions. Since the flow is laminar, the total quantity of ions that we’re able to deliver to the surface of the material becomes greater. This allows the charge to be neutralized quickly, rather than having to sit and “dwell” under the ionized airflow.
With lengths from 3”-108” and (4) four different materials all available from stock, EXAIR has the right Super Air Knife for your application. In addition to shipping from stock, it’ll also come with our unconditional 30-day guarantee. Test one out for yourself to see just how effective the Super Air Knife is on a wide variety of cooling, cleaning, or drying applications.
