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.

Greeting Cards saved by 1″ Flat Super Air Nozzle

A greeting card manufacturer used a liquid coolant plastic nozzle to provide an air assist to divert greeting cards to an auxiliary straight conveyor. Without the air assist the cards would bounce and fly from the conveyor leading to a loss of products and more maintenance.  They used what they had on hand which was a coolant nozzle pictured below.

Coolant Type Nozzle
Liquid Coolant Nozzle uses 32 SCFM at 40 PSIG and 57 SCFM at 80 PSIG.

This nozzle was run at a fairly low pressure of 10 PSIG, but still used 7.8 SCFM at 10 PSIG.  The nozzle worked well, but if run for 24 hours over 250 working days, it costs $702 to supply air to the nozzle. The customer utilized (40) nozzles in their plant which cost them $28,080.  Also, the nozzles were incredibly noisy, since they were designed for liquid flow.

Our customer decided to upgrade to an engineered air nozzle after some time. They needed to cut their air consumption, but still get the job done.  They tested our 1″ Flat Nozzle, but with the standard 0.015” shim it used 5.7 SCFM of compressed air at 10 PSIG. This would be a savings, but after a quick conversation with our Application Engineers, the customer decided to install a 1″ Flat Super Air Nozzle with only a 0.005″ shim. This nozzle 1126-.005 only used 0.9 SCFM of compressed air at 10 PSIG of inlet pressure.  Replace their 40 liquid coolant nozzle would save them 6.9 SCFM per nozzle. 276 SCFM if all 40 nozzles were replaced. Saving 276 SCFM lowered energy bill for their air compressor by $24,840 anuually. Which would mean the simple ROI for $41, 1″ Flat Super Air Nozzle would be 17 days!
