EXAIR manufactures the Super Air Knife, Standard Air Knife and Full-Flow Air Knife. The table below provides a quick comparison of the three styles. The Super Air Knife provides the best performance with a 40:1 air amplification ratio, making it the most efficient. It is the best choice for all applications. The Super Air Knife has a laminar airstream that is uniform, forceful and quiet. Velocity is the highest of all three air knives. Air consumption is lowest of all three air knives. Compressed air inlets are provided on each end and on the bottom. Multiple Super Air Knives can be mounted “end to end” for longer lengths of uninterrupted airflow. The 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. 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" (25mm) longer than the airflow length. The 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. Force is less than the other two styles. Air consumption and sound level falls between that of the Super Air Knife and the Standard Air Knife. Compressed air inlet(s) are provided on the rear. Inlets are available on each end at a small additional charge, however they are not recommended for applications where uniform flow across the length is required. Super Air Knife (shown left) Standard Air Knife (shown middle) Full-Flow Air Knife (shown right) Super Air Knife • Best choice for all applications • Lowest operating cost • Highest efficiency (saves most air) • Quietest • 40:1 air amplification ratio • Compressed air inlets on each end and the bottom • Airflow length and overall length are the same Standard Air Knife • Good choice, lower purchase price • Highest operating cost of the three • Good velocity • Higher dBA rating • Compressed air inlets on each end • Overall length is 1" (25mm) longer than the airflow length Full-Flow Air Knife • Good choice, lowest purchase price • Higher operating cost than the Super Air Knife • Smallest size • Airflow length and overall length are the same EXAIR’s Universal Air Knife Mounting System allows for easy positioning of all EXAIR Air Knives. See page 29 for details. EXAIR’s Plumbing Kits provide properly sized compressed air hose or pipe, and fittings to eliminate pressure loss and provide peak performance. See page 29 and 31 for details.
