This backward-curved centrifugal fan is designed for HVAC air handling and industrial ventilation applications where stable airflow, higher static pressure capability, and low power consumption are required. The backward-curved impeller design delivers efficient performance across a wide operating range and is suitable for ducted systems, filtration setups, and equipment cooling.
Key Features
- Backward-curved impeller for high efficiency and stable performance
- Low power consumption with excellent airflow and pressure capability
- Robust construction for continuous-duty operation
- Flexible motor options (AC / EC) and speed configurations
- Customizable airflow, pressure, wheel size, and mounting pattern
Typical Applications
- Air handling units (AHU) and HVAC systems
- Environmental control units (ECU)
- Industrial ventilation and filtration systems
- Equipment cooling and air circulation
Customization & Quotation
We support custom design and manufacturing based on your operating requirements and installation constraints. To quote accurately, please provide target airflow (CFM / m³/h), static pressure (Pa / in-H2O), operating speed (rpm), motor requirements, and the mounting dimensions.
FAQ
1) What is the difference between backward-curved and forward-curved centrifugal fans?
Backward-curved centrifugal fans generally offer higher efficiency and more stable performance across a wide operating range, and they typically require less power at higher flow rates compared with forward-curved designs.
2) Can you customize the fan to meet our airflow and pressure requirements?
Yes. We can customize wheel diameter/width, impeller design, motor selection, and operating speed to match your target airflow and static pressure requirements.
3) What motor options are available?
AC motors and EC motors are both available. Please advise voltage, frequency, required speed, and any control requirements (e.g., VFD, PWM, or EC control).
4) Can the fan run at 4-pole (1,750 rpm) or 6-pole (1,100 rpm) induction motor speeds?
Yes, the fan can be designed to match typical induction motor speeds. Please provide the target airflow and pressure at the intended speed so we can confirm feasibility and optimize efficiency.
5) What materials and surface finishes are available?
Common impeller materials include galvanized steel and aluminum. Stainless steel and special coatings can be provided upon request depending on corrosion and environmental requirements.
6) Do you provide performance testing or test reports?
Testing and performance verification can be provided upon request. Please share your testing standard or acceptance criteria so we can confirm the scope.
7) What information is needed for quotation?
Target airflow and static pressure, operating speed, motor type/power/voltage, installation and mounting dimensions, application details (duct length, filters, temperature), quantity, and destination for shipping.
8) What are the MOQ and lead time?
MOQ and lead time depend on the fan size and customization level. Please share the required quantity and target schedule, and we will confirm accordingly.
