W4-72 Series 550°C High-Temperature Centrifugal Fan with Backward-Curved Airfoil Blades and Water-Cooled Drive System

The W4-72-11 series is a professional industrial-grade high-temperature centrifugal fan engineered for conveying non-corrosive high-temperature gases in demanding thermal environments. It operates continuously at gas temperatures up to 550°C and handles gas streams containing dust and hard particles up to 150 mg/m³, making it ideal for industrial heat exhaust, furnace ventilation, and high-temperature process air systems.

This fan features a single-sided air intake cantilevered structure with C-type belt transmission, providing reliable performance and easy maintenance. Available in both right-rotating and left-rotating configurations with multiple outlet angle options for maximum flexibility to match existing ductwork and installation requirements.

• Extreme High-Temperature Resistance: Impeller constructed from premium heat-resistant stainless steel for long-term durability at 550°C. Special high-temperature resistant coatings and seals prevent thermal degradation. Designed to withstand repeated thermal cycling without structural deformation.
• High-Efficiency Aerodynamic Design: 10 backward-curved airfoil-shaped blades optimized for high airflow and pressure performance. Curved front disc and flat rear disc configuration minimizes turbulence and energy loss. Integral molded air inlet with streamlined cross-section ensures smooth gas entry.
• Reliable Water-Cooled Drive System: Heavy-duty water-cooled bearing housing effectively dissipates heat during continuous high-temperature operation. Precision-machined main shaft and pulleys ensure stable power transmission. Sealed bearing design prevents dust and debris ingress, extending service life.
• Flexible Configuration Options: Two rotation directions: Right-rotating (clockwise) and Left-rotating (counterclockwise). Multiple outlet angles (0°, 45°, 90°, 135°, 180°, 225°) to accommodate various duct layouts. C-type belt transmission allows easy speed adjustment for different performance requirements.
• Robust Industrial Construction: Heavy-gauge steel casing with reinforced welding for structural integrity. Cantilevered impeller design simplifies maintenance and component replacement. Anti-vibration mounting base reduces operational noise and vibration.

Note: All performance parameters can be customized according to specific application requirements. Please contact our engineering team for tailored solutions.
