RTC All-Aluminum Roof Fans – Keruite Product Introduction

About this video

Keruite Air Conditioning Group presents our RTC series all-aluminum roof fans, engineered for reliable rooftop ventilation in industrial and commercial applications. These centrifugal roof exhaust fans feature a fully aluminum construction that combines lightweight durability with superior corrosion resistance, making them ideal for a wide range of ventilation scenarios. What Are RTC Roof Fans? RTC roof fans are centrifugal rooftop exhaust units developed using advanced European and American technology. The all-aluminum construction offers significant advantages over traditional glass fiber reinforced plastic roof fans – stronger, lighter, and more durable, reducing structural load on roofs while maintaining excellent weather resistance. The motor and drive components are isolated from the exhaust airstream, protecting them from smoke, oil mist, moisture, and corrosive contaminants, substantially extending service life. Key Product Features: All-Aluminum Construction: Lightweight yet robust, with excellent corrosion resistance and weatherproof performance. Ideal for steel structure buildings where weight reduction is critical. Isolated Drive Compartment: Motor, bearings, and drive components are completely isolated from exhaust airflow, protecting against smoke, grease, moisture, dust, and corrosive gases. This design ensures reliable operation even when handling contaminated air. Backward-Inclined Centrifugal Impeller: Features a backward-curved aluminum impeller with high balance grade, delivering high static pressure with stable, quiet operation. The non-overloading performance characteristic prevents motor overload. Streamlined Aerodynamic Design: Double-curve venturi inlet and smooth-flow volute housing minimize turbulence and reduce noise. The aesthetically designed hood complements modern architectural requirements for exposed rooftop equipment. Anti-Corrosion & Durable: Aluminum construction ensures long-term corrosion resistance without painting, maintaining appearance and performance in harsh environments. Forced Cooling Technology: Utilizes negative pressure from impeller rotation to actively cool the motor compartment, extending bearing, motor, and belt life.
