Product Key Selling Points

• Precision-adjustable air gap: 0.2 – 4.0 mm, the finest lower limit in its class

• Four inlet diameter options (Φ32 / Φ38 / Φ45 / Φ51) — direct fit to most standard air supply lines

• Three inlet positions: End (dual), Side (M8), Bottom — maximum installation flexibility

• Compact 50W × 120H mm cross-section fits inside confined machine frames and multi-knife arrays

• Custom length from 50 mm to 2500 mm, OEM/ODM supported — factory direct supply

Product Structure & Working Principle

• Single aluminum alloy extrusion body — lightweight, rigid, and corrosion-resistant

• Internal plenum chamber equalizes static pressure, ensuring uniform airflow across the full knife length

• Tapered internal acceleration duct converts plenum pressure into high-velocity exit airflow at the knife slot

• Precision-machined outlet slot with on-site adjustable gap (0.2 – 4.0 mm) via edge adjustment screws

• Silicone gasket seals at both ends prevent pressure loss and maintain consistent slot velocity edge-to-edge

Application Scenarios

The Type-B Air Knife is optimized for precision and compact-space applications across a wide range of industries:

• PCB & Electronics Cleaning Lines — precision moisture blowoff after chemical rinse cycles

• Optical Film & Display Glass Processing — ultra-fine airflow for droplet removal without surface damage

• Pharmaceutical & Medical Device Lines — surface drying in clean-room or hygienic environments

• Narrow Conveyor & Multi-Knife Arrays — compact cross-section slots into tight machine enclosures

• Wire, Thin Strip & Precision Profile Drying — continuous blowoff on small-gauge or delicate substrates

• Label & Coding Stations — surface moisture removal before printing or adhesive application
