Industry-Leading 350 CFM Airflow

The Blizzard NXT stands out with its 350 CFM airflow system:

• High-output fan and motor combination
• Efficient air distribution across the evaporator coils
• Faster cooling down times
• Better temperature consistency even in extreme heat
• Improved energy performance

Multi-Zone Control Ready

Includes a pre-installed electronic board that supports Multi-Zone control — pairs with compatible Dometic multi-zone thermostats (like the CCC2 architecture or the modern Micro-Air EasyTouch 350) to manage this AC as part of a multi-zone climate system.

Aerodynamic Design

• Sleek modern styling that reduces wind resistance
• Improved fuel efficiency at highway speeds
• High-impact UV-stable injection-molded shroud — withstands extreme sun exposure
• Composite base pan engineered for durability
• Long-term durability under environmental extremes

Quiet Operation

Built-in vibration isolation minimizes compressor noise — meaningfully quieter than legacy rooftop AC designs.

Environmentally-Friendly R410A Refrigerant

Uses R410A refrigerant — releases heat more efficiently than older refrigerants and is environmentally friendly.

Black Finish

Sleek black finish complements modern RV exterior styling.

⚠️ Cosmetic Note
