Installed near the cold water basin on the outside of the tower body, the air inlet louver draws air into the tower. The stainless steel air inlet louver features a special design tilted towards the inside to prevent the sprinkled water from side leakage. It can also prevent dust accumulation and direct sunlight. Additionally, the air inlet louver features low air resistance and is installed at both sides of the unit for easy installation, disassembly, and cleaning.
