PCB Cleaning Lines — precision moisture and flux residue removal after SMT soldering or chemical rinse
Surface Drying (Bottles / Small Parts) — targeted blowoff on curved or recessed surfaces without damage
Dust Removal — ultra-fine airflow for particle displacement on optical lenses, sensors, and precision components
Heated Process Lines — high-temp seal (≤250°C) allows use in dryers, ovens, and thermal treatment equipment
Multi-Knife Array Systems — ultra-slim 50×100mm body enables high-density knife installation in narrow machine frames
Printing & Coding Stations — 0.1mm minimum gap delivers precise, non-damaging air delivery for label and ink drying
Product Key Selling Points
l Ultra-precision adjustable air gap: 0.1 – 2.0 mm — the narrowest minimum gap in the lineup, ideal for delicate surface applications
l Four inlet diameter options (Φ32 / Φ38 / Φ45 / Φ51) for direct compatibility with most standard compressed air lines
l Three inlet positions: End (both sides), Side, Bottom — engineered for maximum installation flexibility
l Ultra-slim 50W × 100H mm cross-section — purpose-built for multi-knife arrays and space-critical machine interiors
l High-temperature silicone gasket seals (≤250°C) at both ends — reliable airtight performance in heated process environments
Product Structure & Working Principle
l Single-piece aluminum alloy extrusion body — minimal weight, maximum rigidity, no corrosion
l nternal plenum chamber distributes static air pressure evenly across the full knife length before acceleration
l Tapered internal duct channels pressurized air into a high-velocity laminar sheet at the precision outlet slot
l Outlet slot adjustable from 0.1 mm to 2.0 mm — fine-tune on-site without disassembly or specialized tooling
l High-temp silicone gasket end seals (≤250°C) lock pressure inside the blade body and maintain uniform exit velocity from end to end
Application Scenarios
The B-C Air Knife is engineered for applications demanding ultra-fine airflow control in compact or high-temperature process environments:
l PCB Cleaning Lines — precision moisture and flux residue removal after SMT soldering or chemical rinse
l Surface Drying (Bottles / Small Parts) — targeted blowoff on curved or recessed surfaces without damage
l Dust Removal — ultra-fine airflow for particle displacement on optical lenses, sensors, and precision components
l Heated Process Lines — high-temp seal (≤250°C) allows use in dryers, ovens, and thermal treatment equipment
l Multi-Knife Array Systems — ultra-slim 50×100mm body enables high-density knife installation in narrow machine frames
l Printing & Coding Stations — 0.1mm minimum gap delivers precise, non-damaging air delivery for label and ink drying
