Nextac Model V
Nextac Model V is designed to fit standard VTAC closets and louvers, serving as an ideal replacement for existing VTAC units and a premier choice for new construction projects. While it maintains a foundational structure similar to traditional VTAC units, Model V distinguishes itself through its unique design and technological advancements.
Featuring exceptionally flexible ducting Model V allows for room supply from the top or sides, room return air from the sides or front, and condenser intake/exhaust from the rear, left, and right sides. In contrast to noisy VTAC operation, Model V operates with whisper-quiet efficiency. Its energy efficiency is powered by a twin rotory BLDC inverter compressor and integrated ERV, surpassing traditional VTACS, especially during electric heating and outdoor air utilization.
Unlike traditional VTACS that necessitate placement on an external wall, Model V offers the flexibility to be installed anywhere in the room and ducted to the outside. Moreover, it provides the capability to duct into two rooms, each with its own supply and return.
