The DWT-IV Non-Powered Roof Ventilator is a natural ventilation solution designed to improve indoor air circulation without consuming electricity. Utilizing wind energy and thermal convection principles, the ventilator continuously extracts hot air, smoke, moisture, and stale air from buildings while promoting fresh air intake.
Unlike powered roof fans, the DWT-IV operates entirely without motors or electrical components, making it an energy-saving and maintenance-free ventilation solution. The turbine rotates naturally under wind pressure, creating negative pressure inside the building and enhancing air exchange efficiency.
Manufactured from high-quality aluminum alloy, galvanized steel, or stainless steel, the DWT-IV roof ventilator offers excellent corrosion resistance, durability, and weather protection. It is widely used in factories, warehouses, workshops, logistics centers, agricultural buildings, and commercial facilities where continuous natural ventilation is required.
