ABSTRACT:
A device for sterilizing a forced air flow by means of ultraviolet radiations, comprising an elongated housing provided with reflecting inner surfaces accomodating at least an ultraviolet radiations source and a fan for sucking air into the device and sending it out after being subjected to the ultraviolet radiation in an air flow passage.
The device provides at each ends means for shielding and absorbing the ultraviolet radiation to prevent the dispersion thereof outside the device, made up by an optical labyrinth formed by parallel and spaced fins.
