AIRCRAFT AIR CONDITIONING UNIT The 804 Series is a line of self contained, fully portable air conditioning units suitable for single connection aircraft throughout the world. The ACU-804 has sufficient capacity to achieve and maintain comfortable cabin temperatures on any narrow or medium bodied aircraft in any climate. The simple but rugged design consists of a diesel engine directly driving for refrigeration compressor and blower. Additionally, a hydraulically driven condenser fan exhausts waste heat directly upward making it immune to performance fluctuations due to varying wind conditions and minimizing heat and noise radiated to the immediate ramp area.Weight: 9,000 lbs
