ACI Air knife Systems are a cleaning, drying and cooling device used in both manufacturing and other processes. By creating a high intensity, balanced sheet of laminar airflow across the entire length of a component, an air knife has the ability to clean, dry or cool components, webs and conveyors..
The number of manufacturing applications suitable for air knives is bewildering. Typically they are used for cleaning, drying and cooling any type of surface ranging from cans and bottles to textiles and extrusions.
Examples:
• Removing residue water from bottles and cans prior to product labelling, ink jet coding and packing operations.
• In conveying systems air knives are used on continuously produced parts or products. In the Cement Industry ACI air knives can be used to remove dust and gravel from the conveyor. Rubber extrusion used in making seals for car doors and windows require a dip in hot salt potassium nitrate to give it a gloss. An air knife can be used to blow off the excess salt to restore the gloss.
• They can be used to remove viscous contaminants from a surface. Cutting oil used in the production of threaded metal rods can be blown away by an air knife.

Nex Flow™ air blade™ air knives are superior to competitive units for the following reasons:
- All our air knives are full flow which means they can be put end to end for continuous flow and takes up less space in tight areas. Even one competitor's so-called full-flow standard answer to our Nex Flow™ standard air blade air knife is not nearly as efficient as ours by their own published values and is only a small, flimsy version in comparison.
- All our air knives come with a stainless steel shim to maintain the gap for the compressed air to exit. Many companies use plastic shims which may be "squeezed" for uneven flow but more important, no matter how clean you make the compressed air line, the plastic will wear. Plastic shims is one of the biggest complaints customers have with air knives - Nex Flow™ however uses stainless steel shims as a standard in all air knives.
- Easy mounting. Some air knife designs are difficult to mount requiring them to be taken apart, often effecting flow and making the job of mounting more difficult. All Nex Flow™ air knives have convenient mounting holes.
- All Nex Flow™ aluminum air knives are anodized while many competitors do virtually nothing to the aluminum for protection. In fact, if you want any better protection they try to get you to by more costly stainless steel when simple anodizing is less costy and already "standard" with Nex Flow™.
- Flexibility in connections. Except for the very short lengths, both standard and X-stream™ versions have compressed air ports at the ends and the back for flexible choice in air input. |

Air Wipe Blow-Off System - Ring-Blade™:
Air Wipe Blow-Off System - Ring-Blade™ from Nex Flow™ is easy to mount and maintain and reduces both compressed air consumption and noise levels.
It produces a "laminar" flow of air along its 360º angle using the "Coanda" effect which "entrains" a large volume of air from the surrounding area along with the small amount of compressed air from the Ring-Blade™ air-saver wiper-blade to produce an output flow up to 30 times.
Air Wipe Blow-Off System - Ring-Blade™ pay back on compressed air savings can be as soon as a few weeks in some applications when compared to nozzle "rings" or simple annular slots used by other air wiping systems.
Blow-off, cool & clean items like pipe, cable, wire and hose with the Air Wipe Blow-Off System Ring-Blade™ from Nex Flow.

Static Eliminator - Air-Blade Ionizer:
The Standard Air-Blade Ionizer combines the superior designed Standard Air-Blade™ Air Knife with a quality static bar made by Haug, a world leading static control manufacturer. Charges can be eliminated quickly, even over large distances and surface area.
The Standard Air-Blade Ionizer uses a small amount of compressed air for a powerful, and adjustable force with "laminar" flow to eliminate charges in applications where static bars cannot reach or where high speeds are a factor.
Normally the Standard Model RN Haug brand static bar can address most applications. For extremely high speeds and high charges the extra powerful VS model is used. For washdown applications (such as pharmaceutical areas), even a washable model is available at extra cost.
All Haug static bars come with a patented safety connector and fully shielded cable. The power supplies are "repairable" and are so well made, that we offer a two year warranty on them (one year on the bars).
Features:
- Connections on the back or ends
- It flows from end to end (full flow).
- Stainless steel models are available for high temperature and corrosive models.
- Models are designed for easy cleaning and prevention of dirt entering the static bar, minimizing potential damage.
- Patented connectors with the ground intrinsic to the cable design.
- Instant ON/OFF with no moving parts.
- Repairable Power Supply with a two year warranty. |

A SIMCO anti-static bar with airknife combine the effects of air amplification and ionisation to produce a high-velocity ''sheet'' of ionised air (amplification ratio as high as 25:1). This combined effect can be used for static neutralising and dust removal in a single operation, for instance in the automotive finishing, printing, packaging, plastics and textile industries. The airknife is very compact and does not have any moving parts. SIMCO anti-static bars produce an electrical field which causes air molecules to break down into positive and negative ions. These ions are
picked up by the high-velocity airflow produced by the airknife and propelled into the work area where they neutralise the charged surface or product. |
