Bifurcated Fan Technical Specifications
Core Construction Features
Bifurcated fans employ a split casing design that isolates the motor from hostile process air. The impeller connects to the motor through a sealed shaft assembly, ensuring reliable performance in extreme conditions.
Standard Materials
- Housing: Hot-dip galvanized steel for corrosion resistance
- Impeller: Die-cast aluminum with aerofoil blade design
- Shaft: High-grade stainless steel
- Bearings: Sealed, maintenance-free design
- Motor Housing: IP55-rated enclosure
Performance Parameters
Our bifurcated fans deliver airflow capacities up to 3,600,000 m³/h with static pressure reaching 3500 Pa. Temperature handling varies by model:
- Standard Units: Up to 90°C (194°F)
- High-Temperature Models: Up to 230°C (446°F)
- Speed Control: VFD compatible
Size Range
Select from standard metric diameters of 175mm to 1000mm or imperial sizes from 15″ to 48″. Custom sizes available for specific applications.
Motor Specifications
All units feature three-phase AC motors with IP55 protection and Class F insulation standard. Motors mount in B3 foot or B5 flange configurations, supporting frequency inverter operation for precise speed control.
Installation Flexibility
- Horizontal or vertical mounting
- Flanged connections standard
- Optional flexible connectors
- Multiple orientation options
- Suitable for indoor and outdoor installation
What makes bifurcated fans different from standard fans?
Bifurcated fans feature a split housing that isolates the motor from the airstream, enabling them to handle high temperatures up to 230°C, corrosive gases, and particulate-laden air while protecting the motor. This design ensures reliability in harsh conditions where standard fans fail.
Bifurcated Fan Manufactures
Common Applications
Bifurcated fans excel in environments where standard fans face rapid deterioration. Their split-design construction handles challenging conditions while maintaining consistent performance across diverse industrial settings.- Industrial Process Extraction
Removes high-temperature gases, fumes, and particles from manufacturing processes while protecting motor components from contamination. - Commercial Kitchen Ventilation
Extracts grease-laden air and steam at temperatures up to 90°C while preventing oil and food particles from reaching the motor assembly. - Chemical Processing
Handles corrosive vapors and aggressive chemical fumes by isolating the motor from the contaminated airstream. - Paint Booth Operations
Exhausts paint overspray and volatile organic compounds (VOCs) while maintaining consistent airflow rates required for proper coating application. - High-Temperature Manufacturing
Ventilates hot gases from furnaces, kilns, and heat treatment processes with temperatures reaching up to 230°C. - Textile Production
Removes fiber-laden air and process heat from textile manufacturing while preventing fiber accumulation on motor components.
