Dual Steel Axial Fans
The advantages of the dual axial fan are two fold. First, there is more air volume
produced and so therefore more air in the canopy is displaced with chemically laden air.
Secondly, as the air from the inboard and the outboard fan meet lots of turbulence is created
and this tumbling of air pushes and pulls the canopy in a way that exposes more surface area of the target zone.
