Narrow adjustable edge gap: 0.5 – 1.5 mm — suitable for controlled hot-air drying, precise blow-off, and surface treatment where excessive air volume is not needed.
50W × 115H mm aluminium alloy body — stable internal air distribution for compact drying stations, component lines, and medium-width production equipment.
End, side M6, and bottom inlet options make pipe routing easier for horizontal lines, vertical frames, overhead equipment, and compact drying stations.
Φ32 / Φ38 / Φ45 / Φ51 inlet sizes support different blower pipe sizes and allow the air knife to match existing production equipment.
Factory-customizable length 100 – 4000 mm with High-Temp Silicone Gasket Seal (≤250°C) and full OEM/ODM support — each unit can be built to the required line width and installation layout.
Product Key Selling Points
• Narrow adjustable edge gap: 0.5 – 1.5 mm — suitable for controlled hot-air drying, precise blow-off, and surface treatment where excessive air volume is not needed.
• 50W × 115H mm aluminium alloy body — stable internal air distribution for compact drying stations, component lines, and medium-width production equipment.
• End, side M6, and bottom inlet options make pipe routing easier for horizontal lines, vertical frames, overhead equipment, and compact drying stations.
• Φ32 / Φ38 / Φ45 / Φ51 inlet sizes support different blower pipe sizes and allow the air knife to match existing production equipment.
• Factory-customizable length 100 – 4000 mm with High-Temp Silicone Gasket Seal (≤250°C) and full OEM/ODM support — each unit can be built to the required line width and installation layout.
Product Structure & Working Principle
• The 50W × 115H mm aluminium alloy body provides a stable chamber for continuous hot-air or blower-air delivery on drying and blow-off lines.
• Air can enter from both ends, from the side M6 inlet, or from the bottom inlet. This allows the same body style to fit different machine directions and pipe routes.
• After entering the body, air first fills the internal plenum. The chamber helps balance pressure along the full custom length, especially on long units up to 4000 mm.
• The internal airflow path guides air toward the outlet edge and converts chamber pressure into a thin, high-speed air sheet for surface drying and cleaning.
• The 0.5 – 1.5 mm adjustable outlet edge gives finer airflow control for sensitive surfaces, smaller parts, and processes that need stable drying without excessive air consumption.
• Both ends use High-Temp Silicone Gasket Seal (≤250°C) to reduce leakage and keep the air chamber sealed during continuous heated-process operation.
Application Scenarios
The Type-F Hot Air Knife is suitable for precision hot-air drying and controlled surface cleaning where a narrower outlet gap is preferred.
• PCB Cleaning Lines — controlled air gap supports moisture removal from boards and components without using an unnecessarily wide outlet.
• Flat Panel & Glass Processing — narrow adjustable edge helps provide stable, non-contact drying and dust removal on smooth surfaces.
• Pharmaceutical & Medical Device Lines — suitable for controlled drying of small parts, containers, and precision components in equipment frames.
• Label & Coding Stations — removes surface moisture before printing, coding, labeling, or inspection on bottles and packages.
• Ultrasonic Cleaning Lines — supports precise blow-off after cleaning where the workpiece surface needs controlled airflow intensity.
• Multi-Knife Array Systems — 100 – 4000 mm custom length and compact inlet options support repeated knife layouts in production equipment.
