Large 80W × 130H mm aluminum alloy body — built for higher air volume and stronger pressure stability than compact air knife models.
Wide adjustable air gap: 0.1 – 4.0 mm. The outlet can be tuned for fine dust removal, normal drying, or stronger water blow-off without changing the air knife body.
Three inlet position options: air inlet from both ends, from the side, or from the bottom. This helps the B-G model fit wide machines with different pipe routing directions.
Φ76 large-bore inlet — suitable for high-volume blower systems where the air knife must supply a strong, continuous air sheet across a wider working width.
Factory-customizable length 100 – 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
• 80W × 130H mm aluminum alloy extrusion creates a large internal plenum. The larger chamber stores more air and helps stabilize output on high-flow production lines.
• 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 stable mounting.
• The Φ76 inlet feeds a high-volume air stream into the internal chamber. For custom lengths from 100 – 4000 mm, this large inlet helps reduce restriction before airflow is distributed along the blade.
• The plenum equalizes the air supply, then the tapered internal path accelerates the airflow into a flat, high-speed laminar sheet.
• 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 B-G Adjustable Strong Air Knife is suitable for wide or high-flow production lines where a large-bore inlet, stable plenum, and adjustable outlet gap are required.
• Wide-Format Production Lines — factory length customization from 100 – 4000 mm supports wide conveyors, panel lines, and large product widths.
• Metal Sheet & Strip Processing — 80W × 130H body and Φ76 inlet support stronger airflow for coolant removal, chip blow-off, and surface drying.
• Flat Panel & Glass Processing — stable air sheet helps remove water marks, dust, and fine particles before inspection, coating, or packaging.
• Automotive Component Drying Stations — high-volume airflow helps dry stamped parts, molded parts, and assemblies after washing or leak testing.
• High-Speed Conveyor Drying Systems — large inlet capacity helps maintain drying force when product speed and water carryover are both high.
• 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.
