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.

ITW Vortec's Curtain Transvectors are air amplifiers, which use a small amount of compressed air to produce a strong, high velocity, laminar sheet of air. Ionizing versions of the air knives effectively neutralize static while providing a powerful blowoff to remove accumulated dust, scrap, particles and contaminants on surfaces and finished products. The airflow delivers positive and negative ions to the surface to kill static cling to improve cleaning. Available for a broad range of manufacturing operations, the Curtain Transvectors efficiently handle high-speed drying applications and clean wide areas such as wood panels, laminates, sheets, films and other large objects or flat surfaces. The patented design significantly outperforms similar products in reduced noise levels and providing excellent uniformity of airflow. Compact and easy to install, Curtain Transvectors have no moving parts, provide instant on/off, and are offered in various lengths. Stainless steel models are available, ideal for applications where purity, high temperature or corrosive environments are concerned.

JetStream Air Knife System
The Meech JetStream air knife system is available in two versions:
Ionising
To remove contamination [dust/fibres/dirt] from a surface. Systems are used extensively throughout the automotive/beverage/composite materials/glass and plastics industries.
Non-Ionising
To remove water/moisture from, or, cool a product or surface. Systems are used within the automotive/beverage/food/plastics and fresh produce industries.

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.

By removing excess moisture from product, Key's Air Knife improves plant efficiency, reduces operating costs, and enhances product quality. The Air Knife features an over-line double air plenum with remote high velocity blower that provides both primary and secondary air curtains to strip moisture from product. The product momentarily stops as it flows to the primary air curtain, where it rolls, then proceeds forward for the final pass through the air curtain.
Common Product Applications
- Beans-green, wax, lima
- Berries, cranberries
- Broccoli, cauliflower
- Carrots
- Corn
- French fry strips
- Peaches, pears
- Peas-green, snap
- Vegetables

Air Knife Systems utilize compressed air for industrial applications that include drying, removing excess oils and liquids, dust blow off, and cooling.
An air knife is effective and efficient. The laminar (uniform) sheet of air is projected along the entire length of the air knife to provide an air flow that covers the entire surface of the product. Air Knife Systems from EXAIR have small profiles, are manufactured in various lengths and can be mounted to accommodate many industrial applications involving conveyors and webs, even in tight spaces. Whether your goal is to remove dust and contaminants, cool hot parts or blow off excess oil, water and liquids, the air knife is also energy efficient. By entraining high volumes of room air they use less compressed air and less energy than other blow off products.
