Abstract: Ventilation systems are disclosed that include a base unit having a mounting platform connecting the base unit to a surface. Such base units have a base collar that extends away from the mounting platform and forms a perimeter of a opening through the base unit. Such ventilation systems include a fan unit that has a fan housing and a fan. The fan housing is configured to receive air through an inlet and expel air through an outlet, and the fan is capable of moving air from the inlet to the outlet. Such ventilation systems also include a quick connect interface that has a base feature and a fan housing feature. The base feature is integrated into the base unit, and the fan housing feature integrated into the fan unit; both are capable of detachably connecting together to secure the fan unit to the base unit.

Abstract: Ventilation units of some embodiments comprise bases and housings which define (twist-on) quick attachment couplings via which the bases and housings releasable couple. Units of some embodiments comprise solar panels coupled to the housings and which are pivotable between stowed positions in which they are flush with the housings and extended positions in which they extend at an angle from the housings. Some embodiments provide units comprising bases, housings, and pivotable solar panels wherein the bases and houses couple to each other via quick attachment couplings. Units of embodiments further comprise locks to lock the quick attachment couplings in place and biasing members to bias the locks into their locked positions. Units of some embodiments comprise risers adapted to couple between the bases and housings and which are adapted to be mounted on angled roofs. Moreover, units can comprise fans and 120 VAC supplies.
