Low-height 50W × 77H mm aluminum alloy body — designed for equipment where vertical clearance is limited but a strong adjustable air sheet is still required.
Adjustable air gap: 0.2 – 4.0 mm. The outlet can be tuned from controlled surface cleaning to stronger drying and blow-off work without replacing the body.
Three inlet position options: air inlet from both ends, from the side, or from the bottom. This helps the B-H model fit compact frames with different pipe directions.
Φ38 / Φ45 / Φ51 inlet options — suitable for compact and medium airflow systems where pipe size must match the machine layout.
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
• Low-height 50W × 77H mm aluminum alloy body — designed for equipment where vertical clearance is limited but a strong adjustable air sheet is still required.
• Adjustable air gap: 0.2 – 4.0 mm. The outlet can be tuned from controlled surface cleaning to stronger drying and blow-off work without replacing the body.
• Three inlet position options: air inlet from both ends, from the side, or from the bottom. This helps the B-H model fit compact frames with different pipe directions.

• 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 × 77H mm aluminum alloy extrusion keeps the body height low while retaining an internal chamber for airflow distribution across the blade length.
• 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 Φ38 / Φ45 / Φ51 inlet choices allow the air supply to match compact or medium pipe systems. For custom lengths from 50 – 4000 mm, the plenum distributes 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 and cleaning.
• The outlet edge size is adjustable from 0.2 – 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-H Adjustable Strong Air Knife is suitable for machines that need a compact body, flexible pipe routing, and adjustable airflow control in limited installation space.
• Compact Conveyor Drying Lines — 50×77H body fits under guards, rails, and limited-height machine frames.
• PCB Cleaning Lines — adjustable 0.2 – 4.0 mm edge gap helps control air impact for moisture removal and particle blow-off.
• Label & Coding Stations — low-height body can be installed close to product flow for localized drying before printing, marking, or labeling.
• Food & Beverage Packaging Lines — compact inlet options support bottle, cap, pouch, and package surface drying where space is tight.
• Multi-Knife Array Systems — smaller body size allows several air knives to be arranged around products or conveyors.
• 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.

Factory Capability · Customization · Service
• QXY processes the 50W × 77H mm aluminum alloy air knife body, inlet ports, edge parts, and sealing surfaces with in-house CNC machining for controlled dimensional accuracy.
• Custom blade length is supported from 50 – 4000 mm. The air knife can be matched to conveyor width, product width, or equipment frame space.
• Configuration options include inlet position, inlet pipe diameter, air gap range, mounting method, and surface finish. End, side, and bottom inlet layouts can be selected according to pipe routing.
• OEM and ODM orders are accepted. Customers may provide drawings, samples, machine photos, or written application conditions for engineering confirmation.
• High-Temp Silicone Gasket Seal (≤250°C) is fitted as the standard end sealing solution, helping reduce leakage without requiring an extra sealing upgrade.
• Before shipment, each customized unit is checked by pressure test, edge-gap calibration, inlet-position inspection, and dimensional confirmation.
