EXAIR Standard Air Knife Keeps Bottles Free From Contaminants

Recently I worked with a customer on an application to remove contaminants from the inside of glass bottles. During production, dust from the ambient environment was collecting inside of the bottles. They needed a way to remove it prior to filling. The solution was to briefly pause the conveyor, pulsing air into the bottles to free any dust that had accumulated. Their problem was that while the dust was blowing out of the bottle without an issue, some of it was settling back down into the bottles.


The customer needed a way to mitigate the risk of dust particles resettling into the bottles after it was removed. The solution was to install a Model 2012 12” Standard Air Knife to provide a curtain of air across the top of the bottles, catching any freed dust particles and blowing them away from the conveyor.

After noticing positive results, we wanted to take things one step further and help to reduce overall air consumption in the process. The blowoff was achieved with (8) ¼” open tubes operating at a pressure of 80 PSIG. Although they were only operating for a fraction of a second, they still consume a whopping 33 SCFM! Replacing them with Model 1101 ¼” NPT Super Air Nozzles (14 SCFM at 80 PSIG) resulted in compressed air savings of 58%!!

In addition to saving compressed air, the noise level was also dramatically reduced. At just 74 dBA, we’re below the threshold for an 8-hour exposure time for operators according to OSHA. Where earplugs were necessary before, they’re now able to operate safely without the need for PPE to protect their hearing. The second most effective fundamental method of protecting workers, according to NIOSH, is to substitute or replace the hazard with an engineered solution. It’s not possible to eliminate the hazard as a compressed air blowoff was necessary, but the next best step is to replace it with something safer.


In addition to complying with OSHA 1910.95(a), the Super Air Nozzle also cannot be dead-ended. In applications for compressed air blowoff with unsafe nozzles, pipes, or tubes, the pressure must be regulated down to below 30 PSIG according to OSHA 1910.242(b). The installation of an engineered compressed air nozzle by EXAIR allows you to operate safely at much higher pressures.

If you have inefficient blowoff processes in your facility, give one of our Application Engineers a call. We’ll be happy to take a closer look at your application and recommend a safe, reliable, engineered solution!

Ion Air Jets Make Beekeeper’s Operation As Sweet As Honey

A honey producer sells their product in specialty glass jars. They pay a premium for these jars, as they enhance the appearance of their product, so the “visual” is obviously very important to them. So much so, that they’re willing to go to great lengths to make sure that the jars are sparkly clean and pristine before filling them with honey.

It’s a given that the inside needs to be clean…it’s a food product, so, of course, there’s a thorough cleaning process for that. The outsides of the jars, though, would sometimes have a little dust or debris left over in the ‘nooks and crannies’ which took away from the crystal clear appearance of the rest of the jar.

They got a Model 8494 GEN4 Ion Air Jet Kit, which they use to remove all of this dust & debris from the outside of the bottle, and then they got another Model 8194 GEN4 Ion Air Jet (which uses the same Power Supply, Filter Separator, and Pressure Regulator from the 8494 Kit) to blow an “insurance” blast of ionized air inside the bottle…just in case. “You can’t be too careful” is a popular mantra for folks who make food products, it seems!

Compact, convenient, easy to use: EXAIR Model 8194 GEN4 Ion Air Jet creates a focused blast of ionized air for static dissipation and cleaning.

Ionized air is extremely effective for ensuring the cleanliness of glass surfaces. Window makers love our Super Ion Air Knives. Some big name sunglasses manufacturers use our Ion Air Jets to ensure the highest quality and consistency of their products. Ion Air Jets and Ion Air Cannons are commonly used to keep optics clean & clear in critical vision inspection systems.
