In one aspect, a modular fan system includes a fan, a plenum member adapted to be mounted to the fan and adapted to be mounted to an enclosure, a gasket adapted to be mounted between the plenum member and the enclosure, a filter adapted to be mounted within the plenum member, and a grille adapted to be mounted to the plenum member. In the system, one or more of the fan, the plenum member, the gasket, the filter, and the grille are both assemblable into a first fan assembly and are alternatively assemblable into a second fan assembly. Another aspect also provides a stand-off collar adapted to be mounted to the enclosure, a first grille adapted to be mounted to the plenum member and adapted to be alternatively mounted to the stand-off collar, and an EMI/RFI shielding grille adapted to be mounted to the plenum member. In this system, one or more of the fan, the plenum member, the stand-off collar, the first grille, and the shielding grille are assemblable into both a non-EMI/RFI-shielding fan assembly and are alternatively assemblable into a EMI/RFI-shielding fan assembly.
