Sonic XE Air Knife


Harness the Power of Sonic XE's Teardrop-Shaped Air Knife Design for Superior Performance
Game-changing teardrop-shaped air knife design for various applications
Developed in 1994, Sonic XE "eXtra Efficiency" Air Knife remains a groundbreaking engineering solution that revolutionized the industry with its teardrop-shaped design and high air efficiency. With a wide range of sizes, materials, and accessory options, Sonic offers the most comprehensive lineup of air knives and nozzles designed to meet the unique needs of any application. Our expert engineers will ensure the optimal pairing of our centrifugal blowers with the Sonic XE Air Knives, backed with a written "performance guarantee" for each system. And if Sonic doesn't have a design to meet the challenge, we'll engineer a new one!
How the Sonic XE Air Knife Blade Delivers Uniform and Powerful Airflow
The Sonic XE Air Knife stands out due to its advanced aerodynamic design and precision engineering, making it one of the most efficient air knife solutions on the market. Unlike a conventional flat-blade air knife, its teardrop-shaped cross-section minimizes turbulence and pressure loss, ensuring a consistent and uniform air stream across its entire length. This design results in an industry-leading 95% coefficient of discharge, maximizing kinetic energy transfer while reducing blower power consumption. The air knife's adjustable slot width and high-velocity airflow allow for customized performance tailored to specific industrial applications, whether for rapid drying, heating, precise cooling, debris removal, or static elimination. Moreover, the Sonic XE Air Knife seamlessly integrates with Sonic Air Systems’ high-efficiency centrifugal blowers, creating a complete air management system that delivers superior results with minimal energy input.
A highly efficient air knife engineering solution for industrial drying, cooling, and blow-off applications
- The Sonic XE is the worldwide air knife design standard (often imitated but never duplicated)
- 2” & 3” (51 & 76 mm) XE Air Knife profiles available in stock
- Precision air knife slot widths, adjustable from 0.010" to 0.250" (0.25 to 6.4 mm), produce laminar airflow across the entire air exit slot length
- Materials of construction: extruded aluminum with type III hard anodize high temp with Nylon inlet, end caps and Viton gaskets. Also available in 300 series stainless steel and powder-coated carbon steel
- Air inlets from one to four in any position, based on the total air knife volume required
- Many common lengths of welded 300 series stainless steel air knives with electropolished finish are in stock
- Flexline air nozzles added to air knives for additional blind spot blow-off
- Designed for Sonic blower pressures of 10" to 120" H₂0 (250 to 3048 mmH₂0) and 40,000 FPM (12,192 MPM) velocities
- Intrinsically safe for personnel by avoiding the air embolism hazard associated with some compressed air blow-off designs at 15 PSIG (103.4 kPa) and above
- Reduced power versus compressed air blow-off devices by up to 75%
- Greatly improve blower-powered air impact force compared with slotted pipes and other low-efficiency air knife designs
- Increased Production Efficiency: Delivers consistent, high-speed airflow, reducing drying and cooling time for improved production throughput.
- Significant Energy and Cost Savings: Cuts energy costs by up to 75% compared to traditional compressed air systems.
- Versatility Across Industries: Can be customized to meet specific drying, cooling, and blow-off needs.
- Improved Workplace Safety and Compliance: Operates with lower noise levels compared to compressed air alternatives and meets OSHA safety regulations
- Reduced Environmental Impact: Minimizes carbon footprint by lowering energy consumption.
