Abstract: An air conditioning system. The system may include one or more of fan covers, each having a customized filter placed directly on an open sidewall, a main drain pan with air pockets that act as insulation, an auxiliary drain pan that can be reduced in shape for receiving runoff from the main drain pan, and a self-cleaning mechanism for cleaning the main filter of an air conditioning unit.

Abstract: A blower cover and an air conditioner using such blower. A rollable sheet is locked between two side plates by rollable connectors. A belt plate is secured between the side plates to lock the rollable sheet between the side plates. The belt plate also directs air from the blower. The blower cover can easily be assembled at a work site without welding or expert metal working. The blower cover is used in an air conditioner in which air is forced upwards from the blower and the air is directed into a heat exchange unit by one or more air deflectors. Another air deflector directs air coming out of the heat exchanger in an upwardly direction out of the air conditioner and this air deflector also directs any condensate downwards toward a drain system generally located below the heat air conditioner.
