1″ And 2″ Flat Super Air Nozzles Overview

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.

Part Ejection Improved by Choosing the Right Air Nozzle

Recently, I was able to work with a gentlemen from a stamping company that produces small metal stamped lids for the cosmetic industry.  He was frustrated because the current blow off setup, a copper tube and nozzle (shown below), was too weak and narrow to be effective with parts ranging from 1″ to 2.5″ wide.  Whenever a lid did not get completely discharged, the machine would jam and double hit on the next cycle, ruining (2) parts in the process, not to mention, potentially damaging the the tooling.

After reviewing the process, which is very high speed, we wanted a strong, concentrated blast of air that matched the part profile to maximize the air flow contact patch.  We agreed the model HP1125 – 2″ High Power Flat Super Air Nozzle would be a good nozzle to implement and test.  In addition to the Nozzle, the customer ordered the model HP1132SS Shim Set, to allow for flow and force adjustment of the nozzle to obtain the best possible performance under production conditions.  The HP1125 nozzle provides 2.2 lbs of force with the standard .025 patented shim installed, and can be decreased or increased by changing the shim to .020″ or .030″ thick. Preliminary testing has proven successful, and reliability testing and data collection is underway.
