209 L is part of a new generation of patented Laval nozzles. represents an entirely new phase in blowing technology.
he effect is achieved by surrounding a core jet moving at supersonic speed with a protective sheath of air running parallel
to the direction of the central stream. There is a mix of divergent slots and holes around the Laval orifice that generates a quiet,powerful and laminar air flow. This nozzle provides extremely efficient blowing that utilizes your compressed air optimally
