Compact 42W × 85H mm body — the Type-D model fits production equipment where a larger adjustable strong air knife is difficult to install.
Wide 0.1–4mm adjustable air knife edge — operators can tune the outlet gap for light surface drying, stronger water removal, or dust blowing without replacing the blade.
Three inlet layouts are supported: air inlet from both ends, from the side, or from the bottom. This helps the air pipe avoid frames, guards, conveyors, and nearby equipment.
Φ32 / Φ38 / Φ45 inlet pipe options give practical matching space for different blower or compressed-air pipework designs.
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 the customer's drawing or application requirement.

Product Structure & Working Principle
• The 42W × 85H mm aluminium alloy extrusion forms a compact air chamber. It keeps the body small while still providing enough internal volume for stable airflow distribution.
• Air can enter through both ends, the M6 side inlet structure, or the bottom inlet. The correct inlet direction should be selected according to machine space and pipe routing.
• The internal chamber supports customized blade lengths from 50–4000 mm. On longer knives, the inlet layout should be chosen to keep airflow uniform across the working width.
• After entering the chamber, air is equalized and then guided toward the outlet edge. The narrow outlet forms a continuous sheet of high-speed air for drying, cleaning, or separating surface liquid.
• The 0.1–4mm outlet gap can be adjusted by the edge screws. Adjustment can be made on site to match the required air volume and impact force without disassembling the air knife body.
• Both ends use High-Temp Silicone Gasket Seal (≤250°C) to reduce leakage at the termination points and keep the outlet airflow focused along the working length.
Application Scenarios
The Aluminum Air Knife D is suitable for compact and medium-width equipment that needs adjustable airflow strength and flexible inlet routing.
• Surface Drying — removes water films from bottles, machined parts, plastic components, and cleaned products before packing or the next process.
• PCB Cleaning Lines — compact body and adjustable gap help remove moisture, dust, and process residue around boards and narrow equipment spaces.
• Flat Panel, Glass, and Sheet Processing — continuous air sheet supports edge drying, surface dust removal, and liquid blow-off on flat substrates.
• Automotive Component Drying Stations — works for parts that need directed airflow after washing, rinsing, or coolant removal.
• Overhead and Flush-Mount Installations — bottom inlet and side inlet options help route pipework cleanly when the air knife must be installed close to a conveyor or frame.
• Wide-Format Production Lines — custom length from 50–4000 mm allows the knife to match different conveyor widths and product sizes.
