In most “general” blowoff applications, the conical airflow pattern from a standard round shaped nozzle is ideal when trying to remove dust or light debris from the surface of a part or material. However in certain applications, a focused, laminar flow of air is required to produce the desired result, such as cleaning peanut butter from a fill nozzle or ejecting parts in a stamping operation.
EXAIR manufactures our 1″ Flat and 2″ Flat Super Air Nozzles, which provide a 1″ and 2″ (respectively) wide, forceful stream of high velocity, laminar airflow while consuming only a small amount of compressed air. Both the 1″ and the 2″ are available in Zinc Aluminum alloy, rated up to 250°F (121°C), or 316 Stainless Steel construction, rated up to 1,000°F (538°C)
Their unique design incorporates a specially designed, replaceable shim, to maintain a critical gap between the cap and body, resulting in the focused airflow. They are shipped from stock with a .015″ shim installed.
Using the optional shim kit, the shims can be changed out to .005”, .010” or .020”, which allow you to increase or decrease the force and flow by either opening or closing the gap, providing more or less force and flow to meet the demand of the application.
(Here’s a short video showing how easy it is to change out the shims)
We also offer our High Power versions of these nozzles which feature a thicker shim installed (0.025″) for applications requiring higher thrust and velocity.
If you have an application you would like to discuss or to see how the Flat Super Air Nozzles might improve your process, give me a call, I’d be happy to help.
We occasionally get calls from folks who are looking for “more power” – and it always brings that classic 1990’s sitcom “Home Improvement’s” Tim “the Tool Man” Taylor to mind. Well, not so much Tim’s “more power” mantra, but the ubiquitous response from his long-suffering sidekick, Al Borland:
Al knows it. George Foreman knows it. Lisa knows it. Even Tim knows it, this time.
Sometimes, they’re looking for a product to replace what they’re currently using…something they’re not getting desirable results from. Other times, they have an EXAIR product in place, and it’s just not getting the job done.
Our first response is, of course, to make sure they’re getting a sufficient supply of air to their product, no matter whether it’s ours or not. If you’re familiar at all with our blogs, you know we write about this frequently:
Once we’ve made sure that the product is indeed receiving appropriate air supply, we can look at adding to the flow rate and force of the air stream. We’ve made it easy to do that with a variety of blow off products by designing them with a replaceable shim.
All of our Air Knife products (Super, Standard, and Full Flow) will ship with a 0.002” thick shim installed. These will perform superbly in a wide variety of general industrial blow off applications. If this doesn’t provide the force needed for your application, we carry Shim Sets for any Air Knife that will allow you to double, triple, or even quadruple the air flow for amplified thrust. Some common examples are stubborn debris in tight spaces (like the fins of a fin-and-tube heat exchanger) or removing oil from a corrugated surface.
Like the Air Knives, our Air Wipes (Super and Standard) are built with 0.002” thick shims, which can be easily replaced for additional flow and force. Like when the Air Wipe is getting all the coolant off an extruded & machined part, but some stubborn, hair-like fibers need a little more “oomph” to remove.
Yes, those were real calls I took. Yes, they had sufficient air flow. Yes, the extra shims worked like a champ.
Similar to our Air Knife products, our Flat Super Air Nozzles also incorporate a replaceable shim. In fact, you have your choice of standard Models with a 0.015” thick shim installed, or High Power Models with a 0.025” thick shim. Shim Sets with a variety of thicknesses from 0.005” to 0.030” are available for either of these.
If you have an air blowing application that you’d like to get a little (or a lot) more out of, give us a call. Prepare for a discussion on proper air supply first (of course,) but we’ll be more than happy to help in any way that we can.

A brief video explaining just a few of the benefits to utilizing the EXAIR Flat Super Air Nozzles and how to change the shims which change the force and volume of flow out of the nozzle. Our shims and the adjustable air gap mean you can increase or decrease the volume of air flow and force without adjusting the inlet air pressure.
