Centrifugal Fan

A: We produce forward - curved centrifugal fans, which are suitable for low - pressure, high - flow applications; backward - curved centrifugal fans for medium - to - high - pressure and relatively high - efficiency applications; and radial - tipped centrifugal fans often used in specific industrial processes with high - pressure requirements.

A: Our fans can handle airflow rates ranging from a few hundred cubic meters per hour for small - scale applications to tens of thousands of cubic meters per hour for large industrial ventilation or HVAC systems.

A: The pressure capabilities vary depending on the type and size of the fan. Generally, our backward - curved fans can generate static pressures up to several thousand Pascals, while forward - curved fans are more in the range of a few hundred Pascals for typical applications.

A: For the fan housing, we commonly use materials such as galvanized steel for general - purpose applications, stainless steel for corrosive environments, and in some cases, aluminum alloys for lightweight and non - corrosive requirements. The impeller can be made of various materials including steel, aluminum, or composite materials depending on the application.

A: We use precision - machining techniques during the manufacturing of the impeller. After machining, each impeller is subjected to dynamic balancing tests. We use advanced balancing machines to ensure that the unbalance is within very strict tolerances, which helps in reducing vibration and noise during operation.

A: The efficiency of our centrifugal fans can range from around 50% for some small, low - cost models to over 80% for our high - end, well - engineered backward - curved fans in their optimal operating range.

A: Yes, we can customize fans. We can adjust parameters such as the size, shape of the impeller, the number of blades, the motor power, and the inlet and outlet configurations to meet specific airflow, pressure, and installation requirements of different applications.

A: Under normal operating conditions and with proper maintenance, our centrifugal fans can last between 10 - 20 years. However, this can be affected by factors such as the operating environment (e.g., corrosive or dusty), the frequency of use, and the quality of maintenance.
