The Air Distribution Box (ADB) serves as a vital component in an RV’s air conditioning system, effectively distributing conditioned air throughout the living space. Mounting to the ceiling directly under the roof top air conditioner providing a divider for the interiors intake and discharge. The ADB connects to the air conditioner with four bolts, sealing the A/C to the roof. Equipped with a return air filter ensuring that you enjoy a comfortable, clean, and well-ventilated environment while on the road.
Ceiling Controls for Non-Ducted Applications
This ADB offers controls directly on the unit allow you to control the air conditioner without routing a communication wire to a wall mounted thermostat. The manual dials allow you to set the temperature and fan speed. It is designed for non-ducted applications delivering air directly from the unit itself, without the use of ducts. The air is diffused into the room through a central vent with an open/close slider and four smaller vents on each side to direct airflow.
