Exair 2012SS 12" Type 303 Stainless Steel Standard Air Knife

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.
• 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).
• 12" Type 303 Stainless Steel Standard Air Knife

Applications:

• Part drying after wash
• Sheet cleaning in strip mills
• Conveyor cleaning
• Web drying or cleaning
• Part or component cooling
• Environmental separation
• Pre-paint blowoff
• Bag opening / filling operations
• Scrap removal on converting operations

Advantages:

• Up to 10 dBA noise reduction
• Reduced air consumption
• 30:1 air amplification
• Aluminum or stainless steel
• Compact, rugged, easy to install
• No moving parts
• 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.
