Model V

Nextac’s Model V fits standard VTAC closets and louvers, making it a direct VTAC replacement for existing units and a strong option for new construction. It keeps the footprint of a traditional VTAC while updating the design with modern technology. Flexible ducting enables supply and return from multiple directions, while condenser intake and exhaust can be placed at the rear, left, or right—reducing noise and giving you layout freedom.

Powered by a twin rotary BLDC inverter compressor and an integrated ERV, Model V delivers higher efficiency, especially in electric heating and outdoor air use. Unlike wall-mounted units, it installs anywhere and can serve two rooms with separate supply and return. That versatility makes it a modern upgrade and a reliable VTAC replacement for properties seeking better comfort and efficiency without costly redesigns.
