As well as being equipped for being ducted over longer distances, they can likewise adapt to twists in the ducting. Radial fans are fit to establishment on walls and roofs.
Inline fans can be either hub or outward, yet are not introduced on walls or roofs, but rather in the void or space over a roof. Overall they are radial.
