Forward & Backward Curved Centrifugal Fans 90-3500mm Diameter 3000-25425 Pa Pressure Range for Industrial Applications
Our centrifugal blower range includes both forward curved and backward curved configurations, distinguished primarily by impeller blade geometry and performance characteristics.
Forward Curved Fans (Blowers): Feature impeller outlet angles greater than 90°, optimized for high-pressure applications with parallel blade-to-impeller edge alignment.
Backward Curved Fans (Induced Draft): Utilize impeller outlet angles less than 90°, designed for medium-pressure applications with non-parallel blade configuration.
- Power Efficiency: Backward curved fans demonstrate superior efficiency (80%-90%) due to expanded channel design and reduced hydraulic losses
- Energy Consumption: Forward curved models typically consume more power due to lower operational efficiency
- Noise Levels: Backward curved fans operate with significantly reduced noise compared to forward curved alternatives
