Deep 50W × 120H mm aluminum alloy body — designed to provide higher internal air storage and steadier output than low-profile 50mm-wide models.
Wide adjustable air gap: 0.1 – 4.0 mm. The same air knife can be set for fine particle removal, normal drying, or stronger water blow-off.
Three inlet position options: air inlet from both ends, from the side, or from the bottom. This gives Type-C more flexibility for pipe routing and machine integration.
Φ32 / Φ38 / Φ45 / Φ51 inlet options — suitable for different blower pipe sizes and airflow requirements.
Factory-customizable length 50 – 4000 mm with High-Temp Silicone Gasket Seal (≤250°C) and full OEM/ODM support. Each unit can be built according to drawings, samples, or written equipment requirements.
Product Key Selling Points
• Deep 50W × 120H mm aluminum alloy body — designed to provide higher internal air storage and steadier output than low-profile 50mm-wide models.
• Wide adjustable air gap: 0.1 – 4.0 mm. The same air knife can be set for fine particle removal, normal drying, or stronger water blow-off.
• Three inlet position options: air inlet from both ends, from the side, or from the bottom. This gives Type-C more flexibility for pipe routing and machine integration.
• Φ32 / Φ38 / Φ45 / Φ51 inlet options — suitable for different blower pipe sizes and airflow requirements.
• Factory-customizable length 50 – 4000 mm with High-Temp Silicone Gasket Seal (≤250°C) and full OEM/ODM support. Each unit can be built according to drawings, samples, or written equipment requirements.
Product Structure & Working Principle
• 50W × 120H mm aluminum alloy extrusion creates a deeper internal chamber within a 50mm-wide body, helping store and stabilize incoming air before discharge.
• Air can enter from both ends, from the side, or from the bottom. The side and bottom inlet drawings show M8 threaded fixing positions for secure installation.
• The Φ32 / Φ38 / Φ45 / Φ51 inlet choices allow the air supply to match different pipe systems. For custom lengths from 50 – 4000 mm, the deeper plenum helps distribute air before it reaches the outlet.
• The internal path guides air from the plenum into the outlet slot, accelerating it into a flat laminar air sheet for non-contact drying, cleaning, and blow-off.
• The outlet edge size is adjustable from 0.1 – 4.0 mm. Operators can tune airflow intensity with the edge screws without disassembling the full air knife.
• High-Temp Silicone Gasket Seal (≤250°C) is used at the end sealing positions to reduce leakage and support stable operation in heated or continuous drying processes.
Application Scenarios
The Type-C Adjustable Air Knife is suitable for production lines that need a 50mm-wide body with deeper pressure storage, flexible inlet routing, and a wide adjustable outlet gap.
• PCB Cleaning Lines — 0.1 – 4.0 mm adjustable gap helps control air impact for moisture removal, dust removal, and residue blow-off.
• Surface Drying — bottles, machined parts, molded parts, and general components after washing, rinsing, or cooling.
• Flat Panel & Glass Processing — stable air sheet helps remove water marks and fine particles before inspection, coating, or packaging.• Metal Sheet & Strip Processing — deeper plenum supports steadier blow-off for coolant removal, chips, and surface water.
• Wide-Format Production Lines — factory length customization from 50 – 4000 mm allows the air knife to match different conveyor and product widths.
• Heated Process Equipment — High-Temp Silicone Gasket Seal (≤250°C) supports use near drying tunnels, heat-assisted washing lines, and warm-air blow-off stations.
