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

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
