Exair 2212 12" Aluminum Standard Air Knife Kit

Features:

• 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.
• It is a good choice when a less expensive alternative is required.
• The Standard Air Knife has an airflow that is also uniform and forceful.
• It is louder and uses more compressed air than the Super Air Knife.
• Compressed air inlets are provided on each end.
• Overall length is 1" (25 mm) longer than the airflow length.
• 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).

• Compressed air inlets on each end
• Variable force and flow

How It Work:

• Compressed air flows through the inlet (1) into a plenum chamber.
• It is then throttled through a thin nozzle (2) extending the length of the Standard Air Knife.
• This primary airstream adheres to the Coanda profile (3), which turns it 90° and directs the flow down the face of the unit.
• The primary stream immediately begins to entrain surrounding air (4), for an amplification ratio of 30:1 at 6" (152 mm) away.
