EXAIR Blowoff Systems For Easy Air Nozzle Installation and Aiming

EXAIR engineered Air Nozzles are quiet, efficient, and safe, which makes them ideal solutions for air blowing applications. Selection is largely determined by the size & shape of the desired air flow. Our Air Nozzles & Jets catalog section lists them all, from smallest to largest, along with performance data and airflow patterns, so determining the right one for your application is pretty easy.

The next question is, how do you install it? If it’s replacing another blowing device, odds are, you’re an adapter fitting away (if that) from a quick & easy install:

Compression fittings and Model 1100 Super Air Nozzles transformed the part ejection on this press from “loud and wasteful” to “quiet and efficient” in about a minute.
Swivel Fittings for Air Nozzles.

For new installations, your compressed air drop may be located some distance from the installation. Properly sized pipe or hose can get you from the drop to the point of installation, but what happens when you get there? If you use hard pipe, and you can run it right to the spot where you want the air to blow, your Air Nozzle will essentially be as well supported as the piping. A Swivel Fitting will then allow you to aim it precisely.

Compressed air hose is inexpensive and easy to work with, but it provides no support for a blow off device at the point of use. This is where EXAIR Blowoff Systems come in. Any EXAIR Air Nozzle, up to our 1/4 NPT models, can be fitted with a Stay Set Hose which, all by itself, could be used at the end of a properly supported piping run instead of a Swivel Fitting. It’ll give you more reach – they come in lengths from 6″ to 36″ – and more flexibility in adjustment than the Swivel Fittings.

Precise aiming and location is a breeze with EXAIR Stay Set Hoses.

If you don’t have a pipe manifold like the one shown above, but you have an iron or steel surface in close proximity, a Magnetic Base can be used. EXAIR offers three styles:

Model 9042 Single Outlet Mag Base (left), 9043 Dual Outlet Mag Base (center) and 9029 Swivel Mag Base (right), and some typical uses.

If you’re looking for an efficient, quiet, and safe method of blowing compressed air, EXAIR has you covered with a wide variety of Intelligent Compressed Air Products to choose from. If you have questions about them, or how to mount them for optimal performance, give me a call.

Customizing Blow-off Applications

EXAIR Blowoff Systems are a combination of EXAIR air Nozzles, mag bases and Stay Set hoses. They are available in single or dual outlets and can change the length of the Stay Set Hose and/or the type of nozzle. The flexibility of this product comes in handy when an application require multiple point blowoff or requires different force values from each nozzle. Customizing allows you to fit the nozzles directly to the need of the application.

Example of an EXAIR Blowoff System – these can be customized with different nozzles or length of hose to suit your application best.

One example of this came from a customer who was running a 1950’s era Benchmaster OBI press to stamp out copper lamination and spring steel. There current set-up which can be seen bellow was not really that effective, was loose/floppy, and had been glued together. All of this made it hard for the Technician to line everything up to eject the parts. The technician reached out to us to see if we could substitute some nozzles on our dual Blow-off system with the stay set hose and dual port magnetic base (as seen above). We were able to piece together a special kit for them to swap out one of the 1103 Mini Super Air Nozzles with a 1126 1″ Flat Super Air Nozzle to match the current set-up.

Customizing the nozzles in Blow-off systems can allow for better coverage on awkwardly shaped parts that might have a mix of both smooth surfaces and crevices. Also changing out the length of the Stay Set hoses that come with the kits can allow you to reach all sides when centrally located mounting is not applicable. Using two different length stay set hoses can also allow for two different blow off points to share the same mounting and air line; this means your maintenance team wont have to bring in multiple drops which I’m sure they will appreciate.

Not only can we customize blowoff systems for you, since we manufacture the products here in Cincinnati, OH, we can provide custom features and performance characteristics for you. Our wonderful team of Engineers (just don’t tell them I said that) can design special air knives, nozzles, and even air amplifiers to fit your needs. The image below shows custom Air Amplifiers (with customer specified flanges) that we have built. We can customize our products to fit your needs.
