What Is The Super Air Knife?
- EXAIR’s Super Air Knife is the latest generation of 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-ended pressure and noise requirements
Drying with the Super Air Knife
- The laminar airflow of the Super Air Knife is perfect for removing moisture prior to packaging, painting, labelling, 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
Blowoff with the Super Air Knife
- 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 cleaned
Cooling with the Super Air Knife
- Large volumes of airflow can be generated in very tight spaces due to the compact size of the Super Air Knife
- Flow and force are easily controlled with a pressure regulator, allowing fast or gradual cooling
- Shims can be installed if additional hard-hitting velocity is required
Open, Float, Separate with the Super Air Knife
- The uniform airflow exits the Super Air Knife in a perfectly straight line (does not deflect)
- It is ideal for opening bags and pouches, floating webs, and keeping environments separate
Smart Use Of Compressed Air
- Almost every industrial facility has at least one compressor that is used for hundreds of different tools, equipment and operations
- While most applications for compressed air present no real problems, some do
- Improper use can translate into unnecessary energy costs, high noise levels and dangerous exposure of personnel to high pressure air
Reduce Energy Costs
- The best way to cut energy costs is through proper maintenance and use of the compressed air system
- The most important factor to dramatically boost efficiency is proper use
- The Super Air Knife uses only 1/3 of the compressed air of typical blowoffs used in cleaning, cooling and drying operations and can be instantly cycled on and off
Reduce Noise Levels
- High noise levels are a common problem for many plants
- The sound level of the Super Air Knife is quiet at 69 dBA, even at high pressures of 80 PSIG (5.5 BAR)
- Using the Super Air Knife, it is possible to obtain hard-hitting force without the high noise
Eliminate Harmful Dead Ended Pressures
- Air can be dangerous when the outlet pressure of a hole, hose or copper tube is higher than 30 PSIG (2 BAR)
- In the event the opening is blocked by a hand or other body part, air may enter the bloodstream through the skin, resulting in serious injury
- The Super Air Knife has been engineered for safety and cannot be dead ended
- It is safe to operate at higher pressures and meets OSHA standard 1910.242(b)
