The NAC 9400 DC room air cooler is a specialized, high-capacity evaporative cooling system engineered exclusively for native 12V DC power environments. Built to deliver massive airflow volume while bypassing the energy conversion losses of traditional power inverters, this model connects directly to 12V deep-cycle batteries, solar PV panels, or dedicated DC solar home setups. Operating on an incredibly low power draw of just 35W–45W, it serves as an ultimate cooling solution for off-grid configurations, rural areas, or households looking to run continuous daytime cooling entirely off solar energy with zero impact on the electricity bill.
At its technical core, the cooler features a high-torque 1450 RPM motor wound with 100% pure copper, ensuring exceptional thermal endurance and a long mechanical lifespan under continuous peak summer operation. This low-voltage setup drives a custom 3-wing plastic fan blade that yields a powerful 1350 to 1500 CFM air throw, distributing a chilled breeze across large rooms or lounges. A power-optimized, 12V low-voltage submersible pump ensures uniform and steady saturation across the wide 3-sided prime honeycomb pad network, drawing from an expansive 60 to 65-liter reservoir. For an extra boost of cold air during intense midday heatwaves, users can load the integrated top ice compartment with the included reusable cooling gel bottles.
