Design Options

These centrifugal fans come in both right-hand and left-hand designs. When viewed from the transmission shaft, right-hand fans rotate clockwise, while left-hand fans rotate counterclockwise. The outlet angles for these fans are available in 0°, 90°, 180°, and 270°, and custom angles can be provided if needed. The G6-41 and Y6-41 series fans can be configured with A or D transmission modes for boiler fans and C or D modes for induced draft fans.

Structural Features

1. Impeller – The impeller is made with backward-inclined blades and is welded between a conical cover and a flat wheel disc, ensuring stability. The impeller is dynamically balanced to achieve smooth operation, low noise, and high efficiency.
2. Casing – The volute-shaped casing is constructed from high-grade steel plates, ensuring both durability and stable performance. It can be assembled separately or welded directly to the support.
3. Air Inlet – Designed as a converging streamlined structure, the air inlet is bolted to the side of the fan, ensuring minimal airflow loss and efficient gas flow.
4. Transmission System – The transmission system includes a main shaft, bearing box, and either a pulley or coupling. The system is lubricated with L-AN32 oil, which ensures good sealing and a long operational life.

Performance and Selection

1. Performance Specifications – The G6-41 and Y6-41 boiler fans should be selected based on the required airflow and pressure. Refer to the technical parameters provided for typical operating conditions, and adjust based on specific industrial needs if necessary.
2. Dimensional Performance Conversion – For specific applications, use the dimensionless performance curve for the G6-41 and Y6-41 series fans as a reference. The following formula helps convert these curves into dimensional parameters:
Where:
- $p$ = total pressure (Pa)
- $\psi$ = total pressure coefficient
- $\rho$ = gas density (kg/m³)
- $u_2$ = circumferential speed (m/s)
- $q_v$ = flow rate (m³/s)
- $\phi$ = flow coefficient
- $D_2$ = impeller outer diameter (m)
- $P$ = effective power (kW)
- $\lambda$ = power coefficient
