MOBILE VIEW Super Air Knife™ Quiet, hard-hitting curtain of air for blowoff, cleaning, drying, and cooling. Surprisingly Quiet! - Only 69 dBA! Reduced Air Consumption! Uniform Airflow! 40:1 Air Amplification! What Is The Super Air Knife? EXAIR's Super Air Knife is the latest generation of our engineered air knife that dramatically reduces compressed air usage and noise when compared to other blowoffs. The Super Air Knife offers a more efficient way to clean, dry or cool parts, webs or conveyors. It delivers a uniform sheet of laminar airflow across the entire length with hard-hitting force. Noisy blowoffs become a whisper when replaced with the compact Super Air Knife. Even at high pressures of 80 PSIG (5.5 BAR), the sound level is surprisingly quiet at 69 dBA for most applications! Air amplification ratios (entrained air to compressed air) of 40:1 are produced. Meets OSHA maximum dead-end pressure and noise requirements.

The laminar airflow of the Super Air Knife is perfect for removing moisture prior to packaging, painting, labeling, bar coding and assembly. Common applications include drying parts, rolled steel, circuit boards, webs, bottles, cans and more. Velocity is easily adjusted from a “blast” to a “breeze” with a pressure regulator. The Super Air Knife is ideal for blowing off chips, dirt or water from parts, webs or conveyors. It delivers a uniform sheet of air that has the same force across the entire length. There are no interruptions or “dead spots”, which means all surfaces are dried or...

Super Air Knife Air Knives How The Super Air Knife Works 2 Compressed air flows through an inlet (1) into the plenum chamber of the Super Air Knife. The flow is directed to a precise, slotted orifice. As the primary airflow exits the thin slotted nozzle (2), it follows a flat surface that directs the airflow in a perfectly straight line. This creates a uniform sheet of air across the entire length of the Super Air Knife. Velocity loss is minimized and force is maximized as the room air (3) is entrained into the primary airstream at a ratio of 40:1. The result is a well defined sheet of...

Compare These Blowoffs energy and noise level). Compressed air pressure required for each was 60 PSIG (4.1 BAR) which provided adequate velocity to blow the water off. The blower used had a ten horsepower electric motor and was a centrifugal type blower at 18,000 RPM. The table at the bottom of the page summarizes the overall performance. Since your actual part may have an odd configuration, holes or sharp edges, we took sound level measurements in free air (no impinging surface). There are a variety of ways to blow the water from the bottles shown in the photo below, but which method is...

Super Air Knife Changing Performance By Adding Shims The Super Air Knife is shipped with a Red color .002" (0.05mm) thick shim installed, which works best for most applications. There are, however, some situations that require more force and f low. Thicker shims will increase the gap opening which offers higher velocity and harder hitting force. Air consumption and noise will be slightly higher. Shim sets are included with all kits or can be purchased separately. Kits include a Super Air Knife, shim set, filter separator and pressure regulator (with coupler). Special Super Air Knives A...

Super Air Knife Air Knives Many Lengths Available From Stock in Four Materials EXAIR’s Super Air Knives are available from stock in many lengths and your choice of four materials. The force, flow and air pattern stay the same for each construction. PVDF (Polyvinylidene Fluoride) The aluminum Super 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...

Super Air Knife Air Shielding a Laser Lens Model 110006 6" (152mm) Super Air Knife prevents debris from depositing on a laser cleaning head. The Problem: A dirty lens can affect the quality of cameras, sensors and lasers. Today’s visual inspection systems are highly accurate tools used to monitor dimensions, temperature, finish quality, labeling and much more. These products require clean lenses in order to provide the proper feedback to operators or other machinery within the process. The laser lens to the left is integral to a laser cleaning operation where a laser is used to clear away...
