Deep-plenum 50W × 120H mm cross-section — the tallest body in the 50mm-wide class, providing a significantly larger internal air volume for stable, uniform pressure distribution across long blade lengths
Full 0.1 – 4.0 mm adjustable edge gap — precise on-site gap control from ultra-fine 0.1mm droplet removal to full 4.0mm high-volume air curtain output, without disassembly
Three inlet positions: End (both sides), Side (M8 thread), Bottom — complete installation flexibility for any machine layout, pipework routing, or mounting orientation
Four compatible inlet diameters: Φ32 / Φ38 / Φ45 / Φ51 — direct connection to standard compressed air supply lines across industrial blower and compressor output ranges
Factory-customizable length 50 – 4000 mm with high-temp silicone gasket seals (≤250°C) — every unit built, calibrated, and verified in-house before shipment
Product Key Selling Points
• Deep-plenum 50W × 120H mm cross-section — the tallest body in the 50mm-wide class, providing a significantly larger internal air volume for stable, uniform pressure distribution across long blade lengths
• Full 0.1 – 4.0 mm adjustable edge gap — precise on-site gap control from ultra-fine 0.1mm droplet removal to full 4.0mm high-volume air curtain output, without disassembly
• Three inlet positions: End (both sides), Side (M8 thread), Bottom — complete installation flexibility for any machine layout, pipework routing, or mounting orientation
• Four compatible inlet diameters: Φ32 / Φ38 / Φ45 / Φ51 — direct connection to standard compressed air supply lines across industrial blower and compressor output ranges
• Factory-customizable length 50 – 4000 mm with high-temp silicone gasket seals (≤250°C) — every unit built, calibrated, and verified in-house before shipment
Product Structure & Working Principle
• 50W × 120H mm aluminum alloy extrusion — the additional 120mm height (vs 95–100mm in comparable 50mm-wide models) creates a deeper internal plenum that stores more air volume, directly improving static pressure uniformity across long blade lengths
• Dual end-inlet option feeds compressed air from both ends of the plenum simultaneously — eliminating the pressure gradient that causes velocity drop toward the far end on single-feed long knives
• Side M8 and bottom inlet options allow lateral or underneath pipework routing without end protrusions — useful for confined overhead or flush-mount machine-frame installations
• Tapered acceleration duct converts the equalized plenum pressure into a coherent, high-velocity laminar air sheet at the precision outlet slot
• Outlet gap adjustable from 0.1 mm to 4.0 mm via edge screws — same wide range as the full-size lineup, with no disassembly required for gap changes
• High-temp silicone gasket end seals (≤250°C) maintain airtight pressure containment at both blade terminations across a wide range of operating temperatures
Application Scenarios
The A-H's deeper plenum and wider inlet range make it the preferred choice for longer knife runs, higher airflow demand, and installations where pressure consistency over length is critical:
• PCB Cleaning Lines — deep-plenum body maintains consistent blowoff velocity from the inlet end to the far end of the knife, essential for full-board-width drying uniformity
• Surface Drying — Sheet Materials, Metal Strip & Wide Substrates — stable pressure over long blade lengths ensures even drying across the full substrate width
• Dust Removal on Panels, Glass & Flat Surfaces — 0.1mm minimum gap with uniform pressure distribution delivers consistent particle displacement without localised hot spots
• Long-Run Conveyor Drying Systems (up to 4000mm) — deep-plenum design is specifically suited to knives above 1500mm where single-feed pressure drop becomes measurable
• High-Throughput Industrial Lines — larger internal air volume supports higher volumetric airflow rates, enabling faster drying speeds on high-speed conveyor systems
• Heated Process Equipment — silicone gasket seals rated to ≤250°C allow integration into drying ovens, heat tunnels, and thermal treatment conveyor systems
