Adjustable Air Knife | Multi-Inlet Aluminum Alloy Air Knife | Surface Drying

Adjustable Air Knife | Multi-Inlet Aluminum Alloy Air Knife | Surface Drying

Ultra-wide adjustable edge gap: 0.1 – 4.0 mm — the broadest range combining ultra-precision fine-mist removal at 0.1 mm with heavy-duty air curtain capability at 4.0 mm

Three inlet configurations in one model: End (both sides), Side (M6 thread), Bottom — maximum layout adaptability for any machine orientation

Four compatible inlet diameters: Φ32 / Φ38 / Φ45 / Φ51 — connects directly to most standard compressed air supply lines without adapters

Factory-customizable length: 50 – 4000 mm — from compact 50 mm spot-drying fixtures to 4-metre wide-format industrial drying systems, produced and calibrated in-house

High-temp silicone gasket seals (≤250°C) and full OEM/ODM support — every unit factory-built and verified to your exact specification

Product Structure & Working Principle

A-G-Air-Knife-Design-drawings 

Compact 50W × 100H mm aluminum alloy extrusion body — slim enough for confined spaces, with sufficient internal volume for stable pressure distribution

Three inlet options — end (both sides simultaneously for balanced long-run pressure), side (M6 thread for lateral pipework), and bottom (for flush or overhead mounting) — cover all standard installation geometries

Internal plenum chamber evenly distributes compressed air pressure from whichever inlet is used, across the full blade length from 50 mm up to 4000 mm

Tapered acceleration duct converts equalized plenum pressure into a concentrated, uniform high-velocity laminar air sheet at the precision outlet slot

Outlet gap continuously adjustable from 0.1 mm to 4.0 mm via edge screws — widest adjustment range in the aluminum alloy lineup, no disassembly required

High-temp silicone gasket seals at both ends (≤250°C) maintain airtight blade terminations across a wide range of process temperatures

 

Application Scenarios

The A-G's combination of the widest gap range, most inlet options, and longest customizable length makes it the most versatile single model in the aluminum alloy air knife lineup:

Air_knife_multi-industry_usage_scenarios1 

PCB Cleaning Lines — adjustable gap and multiple inlet options allow the A-G to be retrofitted into virtually any existing wash-line frame configuration

Surface Drying — Bottles, Parts & Sheet Materials — 0.1–4.0 mm range adapts to different product sizes, surface types, and conveyor speeds on the same station

Dust Removal on Panels, Glass & Optical Surfaces — 0.1 mm minimum gap enables controlled, non-damaging particle displacement on sensitive substrates

Wide-Format Drying Lines (up to 4000 mm) — glass, metal sheet, textile, and film production lines covered in a single continuous knife without mid-run joints

Multi-Orientation Installations — end, side, or bottom inlet selection adapts the knife to overhead, lateral, upward-blowing, or downward-blowing mounting requirements

Heated Process Equipment — silicone gasket seals rated to ≤250°C permit integration into drying ovens, heat tunnels, and thermal conveyor systems
