No power roof fan intalliate and principle

The no power roof fan use natural wind-driven or air convention of indoors temperature difference to push the turbine run, exhausted the not fresh air by centifugal force and negative pressure.

Curved blades are the beat results of scientific caculation and it can strickly ensure that no rainwater intrution.

Principles

jienuo roof venting fan without power uses national wides force and thermal convection caused by indoor and outdoor temperature difference to drive the rotate, and thereby draw out stable and impure hot air indoors va centrifugal for negative pressure.
