The NAC 2550 BLDC room air cooler represents the cutting edge of energy-efficient climate control, integrating an advanced Brushless DC (BLDC) motor into a sleek tower design. By replacing standard induction mechanics with a brushless core, this unit cuts operational power consumption down to an incredibly low 35W–65W range, translating to up to 80% utility savings. Equipped with smart hybrid dual-input circuitry, it transitions smoothly between standard AC 220V grid power and a direct DC 12V supply, making it exceptionally friendly for direct solar panel setups, deep-cycle batteries, or household UPS units. The friction-free motor design ensures whisper-quiet performance and a significantly longer operating lifespan.
In place of traditional, noisy fan blades, this premium tower unit utilizes a high-pressure twin centrifugal blower system. This setup generates high static pressure to project a focused, high-velocity 1700 CFM air throw deep into master bedrooms, long offices, or narrow living room layouts. An energy-optimized 1000 Liters/Hour low-voltage pump draws from the space-saving 45 to 50-liter reservoir, continuously soaking the 3-sided prime honeycomb pads for rapid evaporative cooling. The durable, injection-molded polymer frame features simple analog dials on the front deck for quick setting adjustments and sturdy rolling casters for easy room-to-room mobility.
