Full-Flow Air Knife

Provides good performance with a 30:1 air amplification ratio. The Full-Flow Air Knife is the least expensive and is a good choice for tight spaces.

  • In Stock up to 36″ long with force that is less than the other two styles.
  • Air consumption and sound level falls between Super Air Knife and Standard Air Knife.
  • Compressed air inlet(s) are provided on the rear.

The Full-Flow Air Knife borrows engineering elements from our original Standard Air Knife™ with the added benefit of an airflow across its entire length, but will have higher operating costs than the Super Air Knife. They also provide the smallest footprint of our Air Knife line to fit in cramped machine spaces. These are a low cost choice and are available from stock in 3″ to 36″ lengths. The Full-Flow Air Knife is available in aluminum or Type 303 stainless steel. Custom sizes and materials are also available.

Aluminum - The aluminum Full-Flow Air Knife is suited to a wide variety of environments where corrosion or contamination is not a factor. The aircraft grade aluminum construction with plastic shim is very durable for general purpose applications. Stainless steel screws are used to eliminate corrosion in damp locations. It can withstand temperatures up to 180°F (82°C).

Type 303 Stainless Steel - This is the most common grade of stainless steel. It offers good strength and is best suited to mildly corrosive environments. It can withstand temperatures up to 800°F (427°C).
