Eagle beak blade geometry — the precision-profiled beak tip focuses the air stream into a concentrated, high-velocity laminar jet, delivering significantly higher exit velocity and sharper airflow direction than standard flat-slot knives
Largest cross-section in the lineup: 80W × 150H mm — the oversized plenum stores maximum air volume, sustaining high static pressure for powerful, consistent output across the full blade length
Large-bore inlet compatibility: Φ51 / Φ60 / Φ63 / Φ76 — designed for high-capacity industrial blowers and compressors, supporting the high volumetric flow rates that the eagle beak profile demands
Precision-adjustable edge gap: 0.3 – 2.0 mm — fine gap control on a high-power platform, allowing exact airflow intensity calibration for demanding drying and cleaning processes
Factory-customizable length 100 – 2500 mm with high-temp silicone gasket seals (≤250°C) and full OEM/ODM support — every unit built and verified to specification
Product Key Selling Points
• Eagle beak blade geometry — the precision-profiled beak tip focuses the air stream into a concentrated, high-velocity laminar jet, delivering significantly higher exit velocity and sharper airflow direction than standard flat-slot knives
• Largest cross-section in the lineup: 80W × 150H mm — the oversized plenum stores maximum air volume, sustaining high static pressure for powerful, consistent output across the full blade length
• Large-bore inlet compatibility: Φ51 / Φ60 / Φ63 / Φ76 — designed for high-capacity industrial blowers and compressors, supporting the high volumetric flow rates that the eagle beak profile demands

• Factory-customizable length 100 – 2500 mm with high-temp silicone gasket seals (≤250°C) and full OEM/ODM support — every unit built and verified to specification
Product Structure & Working Principle
• Eagle beak blade profile — unlike a standard flat outlet slot, the beak geometry progressively converges the internal airflow path toward a sharp, precision-machined tip, producing a more focused, faster-moving air sheet with greater directional control at the exit point
• 80W × 150H mm heavy-duty aluminum alloy extrusion — the largest plenum volume in the lineup, designed to supply and sustain the high air mass flow rates needed for powerful industrial drying, water displacement, and blow-off applications
• Large-bore inlet ports (Φ51 / Φ60 / Φ63 / Φ76, side M8 thread) connect directly to high-capacity blowers, allowing maximum volumetric airflow into the plenum without restriction at the inlet junction
• Internal plenum chamber equalizes the high-volume air supply evenly across the full blade length before directing it into the beak acceleration section
• Precision-machined beak tip outlet: adjustable 0.3 – 2.0 mm gap for fine-tuning exit velocity and coverage — on-site adjustment via edge screws without disassembly
• High-temp silicone gasket end seals (≤250°C) contain the elevated operating pressures within the heavy-duty blade body at both terminations
Application Scenarios
The B-D Eagle Beak Air Knife is purpose-built for high-power industrial applications where standard air knives cannot deliver sufficient velocity, coverage, or directional precision:
• Heavy-Duty Surface Drying — thick water films, coolant residue, and oil-water mixtures on large metal sheets, steel strip, and structural profiles that standard knives cannot clear at line speed
• PCB & Industrial Component Cleaning Lines — focused high-velocity jet penetrates complex board geometries and recessed component housings for thorough moisture and flux removal
• Dust & Debris Removal on Wide Substrates — eagle beak profile delivers a concentrated, directional air jet for effective particle displacement on glass, panels, and surface-treated materials
• Coating & Painting Line Air Curtains — powerful, precisely directed airflow creates a robust zone separation barrier to prevent cross-contamination between process sections
• High-Speed Conveyor Drying Systems — large-bore inlet and oversized plenum sustain the air volume required to maintain effective drying at elevated conveyor speeds
• Heated Industrial Process Lines — silicone gasket seals rated to ≤250°C support continuous operation in high-temperature drying ovens, heat tunnels, and thermal treatment conveyors
