In one instance, a cooling unit for cooling a refrigerated room includes a fan base and a fan guard that both twist and rotate to change pitch thereby allowing the cooling unit air to be directed in many directions as desired. The fan base has a flange portion and a conduit portion. The conduit portion of the fan base mates with an opening in a conduit member of the fan guard. The opening in the fan guard is sized and configured to form an interference fit with at least a portion of a conduit portion of the fan base while allowing rotation of the fan guard relative to the fan base about the longitudinal axis. The second longitudinal end of the fan-guard conduit member is at least partially angled to allow the rotation about a lateral axis in order to pitch the direction of the grill front wall.
