Abstract : The system comprises a high pressure moisture remover, a conduit interconnecting the moisture remover with the compressor of the turbine engine of the aircraft which provides a source of pressurized air, a high pressure diffuser connected to the outlet of the moisture remover to diffuse the dried pressurized air stream to lower pressure, and an electrostatic precipitator downstream of the diffuser for removing particulate contaminants from the air stream. Alternatively, a low pressure moisture remover may be included downstream of the diffuser. A reactor and absorber may be included in the system to supplement the processes in the removal of chemical contaminants. Vent lines and discharge ports may be connected to the system where convenient, such as to the moisture remover, precipitator and absorber, in order to discharge overboard of the aircraft the liquid effluent and particles removed from the air stream.
