The Dometic Ibis 4 sets a new standard for air conditioning in the mobile living market thanks to several refinements made from the acclaimed Ibis 3. The Dometic Ibis 4 features a powerful dual-cylinder horizontal compressor, a first for the RV industry, which creates a more balanced roof top unit and reduces the level of vibration. In addition to this, the quiet environment that the Ibis 3 achieved has been replicated. The internal ADB has been redesigned, optimizing airflow inside the vehicle. For the first time in an Ibis air conditioner, a turbo-mode fan speed has been included, which allows for rapid cooling inside the RV.
