Coanda Effect Air Knife

JMET Stainless Steel High-Speed Multi-Nozzle Air Manifold is a welded air bar with multiple angled high-speed nozzles for powerful directional blow-off. Made of SS304 / SS316L, it provides evenly distributed high-velocity jets for drying, cleaning and cooling. Widely used in lithium battery, auto parts and ultrasonic cleaning automation lines. Custom sizes are supported.

JMET Tornado Rotary Air Nozzle Large Module adopts multi-nozzle manifold modular design. The tornado vortex nozzle creates high-energy rotating airflow for deep cleaning and drying on complex, grooved and curved workpieces. 360° adjustable nozzles, SS manifold for balanced air delivery. Widely used in lithium battery, auto parts, electroplating and electronic cleaning lines. Custom sizes available.

✅ Available in injection aluminum alloy 6061, JMET air knives are more reliable and energy-saving with higher precision and stronger air flow.
✅ Specially designed structure with less air friction, giving a continuous and uninterrupted air flow whose precision can reach ±5%.
✅ Adjustable outlet width ranges from 0.3 to 3mm.
✅ Customized air knives length up to 6 meters.
✅ Optional inlet specification and positions to fit different kinds of bolt or tube connections, which makes the installation much easier.
✅ Max. sustainable air flow is 400m/s, max. sustainable temperature is 250℃, and max. sustainable pressure is 5kgf/cm2.
✅ Can be used with JIEMING high speed centrifugal blowers, JIEMING high pressure blowers.

✅ No blind spots: Multi-angle air blowing from both sides and bottom, covering bottle shoulder, bottle body and bottle bottom simultaneously to avoid counteracting airflow from opposite blowing.
✅ Closer to bottles: Smaller size than air knives, able to get close to bottle bodies past guardrails. Shorter air cutting distance leads to less energy loss.
✅ Fast bottle type change: Adjustable angle and height for air nozzles. No need to replace the whole system when switching specifications, quick and convenient adjustment.
✅ Thorough purging: Single bottle blowing duration is 3~5 times that of traditional air knife systems, with blowing cycles up to 10~20 times.
✅ Stepped layout: Air nozzles arranged from high to low following fluid mechanics. Water is pushed down step by step without backflow.
✅ Durable material: Main pipe is welded SUS304 stainless steel; air nozzles are made of POM (acetal). Long-term stable performance without deformation from -50℃ to 110℃.
