W9-19 Series 700°C Heat Resistant High-Pressure Centrifugal Fan with Forward-Curved Impeller and Water-Cooled Bearing System

The W9-19 series is a professional industrial-grade high-pressure high-temperature centrifugal fan designed for conveying non-corrosive, non-flammable high-temperature gases up to 700°C with dust and hard particle content not exceeding 150 mg/m³. Its forward-curved impeller design delivers superior pressure performance compared to standard high-temperature fans, making it ideal for high-resistance duct systems and demanding thermal processes.

This series offers 8 standard model sizes (4.5, 5, 7.1, 8, 9, 11.2, 12.5, 17, 18) with multiple transmission options (B-type, C-type, D-type, F-type), left/right rotation directions, and 6 standard air outlet angles. The integral water-cooled bearing system ensures reliable continuous operation even at extreme temperatures, providing a durable solution for the most challenging industrial heat exhaust applications.

• 700°C Extreme High-Temperature Resistance - Robust construction engineered for continuous operation at temperatures up to 700°C. High-quality galvanized steel spiral housing provides excellent thermal stability and corrosion resistance. Designed to withstand severe thermal cycling without structural deformation.
• High-Pressure Forward-Curved Impeller Design - 12 precision-welded forward-curved blades for maximum pressure generation. Optimized impeller geometry delivers high pressure at moderate airflow rates. Perfect for high-resistance ductwork and long-distance gas conveying systems.
• Advanced Water-Cooled Transmission System - Integral water-cooled bearing housing effectively dissipates heat from high-temperature operation. Main shaft manufactured from premium alloy steel for exceptional strength and durability. Multiple transmission options: B-type, C-type belt drive and D-type, F-type direct drive. Sealed bearing design prevents dust ingress and extends service life.
• Aerodynamically Optimized Airflow System - Streamlined converging air inlet minimizes internal flow losses. Smooth spiral housing design reduces turbulence and improves overall efficiency. Precision-balanced rotating components ensure low vibration operation.
• Comprehensive Configuration Flexibility - 8 standard model sizes covering a wide performance range. Two rotation directions: Right-rotating (clockwise) and Left-rotating (counterclockwise) (viewed from motor end). Six standard air outlet angles: 0°, 45°, 90°, 135°, 180°, 225°. Customizable performance parameters to meet specific application requirements.
