Air-Knife Drying: Matching Air Supply to Nozzle Layout
Match a blower to an air-knife nozzle layout by checking coverage, branch flow, manifold loss, operating pressure and the drying result at production speed.

The best blower for a horizontal PCB cleaning and drying line is the one that supplies stable air to every active knife at the required line speed without lifting, shifting or damaging the board. Selection begins with the wet board and nozzle layout, not with a preferred motor size.

Work from PCB drying requirements, air-knife demand and air-path losses to define flow and pressure at one operating point before comparing blower curves.
