Standard Air Knife
Provides good performance with a 30:1 air amplification ratio that is less efficient than the Super Air Knife. It is a good choice when a less expensive alternative is required.
- In stock up to 48″ long with airflow that is also uniform and forceful.
- It is louder and uses more compressed air than the Super Air Knife.
- Available in aluminum and 303 stainless steel
- Compressed air inlets are provided on each end.
The Standard Air Knife™ is EXAIR’s original air knife design. It uses a Coanda profile which turns the airflow 90 degrees from its outlet. This creates a low pressure area capable of entraining ambient air at a ratio of 30:1 while producing a powerful airflow; but does have a higher operating cost than the Super Air Knife. Available from stock in 3″ to 48″ lengths and made from aluminum or Type 303 stainless steel. Custom sizes and materials are available.

Materials
Aluminum - The aluminum Standard 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).
