Industrial Centrifugal Fan Manufacturers

Centrifugal Fan Manufacturer and Product Range

Hangzhou Beron Motor Co., Ltd. is a Centrifugal Fan manufacturer and one-stop factory for AC, EC and DC centrifugal fans. We develop the motor, impeller and control approach together, so an OEM/ODM customer receives a matched air-moving package instead of separate components that may not behave as a system.

The product family is designed for continuous operation in HVAC, air purification and FFU systems, precision ventilation, heat pumps, refrigerated equipment, power electronics, IT communication and new energy storage. With production and R&D centers in Hangzhou and Huzhou, we support projects from airflow calculation to serial delivery and after-sales documentation.

Centrifugal Fan Range: AC, EC and DC

Application Fit and Impeller Design

Centrifugal fans generate airflow by throwing air outward from the impeller, which makes them effective against duct resistance, filters and compact discharge paths. Our centrifugal fan series uses high-strength aluminum alloy or galvanized steel impellers with backward or forward curvature, providing stable operation under high static pressure.

• Backward curved impellers offer efficient operation at medium to high static pressure with lower noise, making them a strong fit for FFU, air purification and precision ventilation units.
• Forward curved impellers deliver high airflow in a compact impeller, which suits roof fans, HVAC blowers and equipment with tight installation space.
• External rotor motor construction positions the motor inside the impeller hub, reducing axial length and simplifying integration into packaged equipment.

We select the impeller shape based on the system resistance curve, installation orientation and available envelope, not just the free-air airflow value. That approach avoids the common mismatch between a fan that moves air well on a bench and one that cannot hold static pressure inside a filter-loaded machine.

Critical Specifications and Series Selection

Every centrifugal fan requirement starts with the operating point. The table below shows how we position the three drive families and what we configure for each application type.

For every series we confirm the voltage, duty cycle, operating temperature and speed control interface before production. This is particularly important for EC and DC fans, where the control board and motor must be matched to the host system’s command signal.

Engineering Value, Controls and Automation Integration

Our EC centrifugal fans combine AC power input with high-efficiency controllable DC motor technology, enabling more than 70% energy savings compared with traditional AC models in many operating profiles. Optional Modbus RTU adds centralized system management and fault diagnosis, which is valuable for HVAC networks, data centers and cleanroom installations that require remote monitoring.

Our DC centrifugal fans are built for precision-sensitive applications such as telecommunications and medical technology. They support PWM speed regulation and FG signal output, giving the host controller a real-time feedback path and allowing the fan to maintain the required airflow as filters load or ambient temperature changes.

When your machine uses analog or bus control, we confirm the interface during the selection stage: voltage and frequency for AC fans, 0-10V or PWM for EC and DC fans, and the communication protocol needed for centralized supervision. This engineering coordination is part of our standard project support, not an after-sales problem.

Quality Assurance, Testing and Compliance Evidence

We operate an ISO9001:2015 quality management system, and our products carry CCC and CE certification while passing RoHS and UL tests. Certification records are available for review as part of the project file, and relevant compliance documents can be included with the quotation.

• Wind tunnel and noise laboratories validate airflow, static pressure and sound levels before product release.
• Motor performance and aging laboratories verify electrical, thermal and endurance characteristics under continuous duty.
• Impellers undergo strict dynamic balancing calibration to reduce vibration and extend service life.
• Factory acceptance testing and third-party inspection support can be arranged before shipment.

Our quality approach covers raw material control, motor assembly, impeller balancing, final function testing and packaging verification. This matters for distributors and equipment builders who need consistent serial production rather than a fan that works only in a prototype.

Project Coordination, Installation and Delivery Scope

After order confirmation, we take responsibility for supply chain coordination, schedule control and pre-shipment verification. This keeps a clear execution channel between customers, our factory and any specialized manufacturing partners we use for non-standard variants.

• Technical documentation, drawings and operating instructions accompany the delivery.
• Online installation guidance and videos are provided; for large orders, engineer visits can be arranged under separate terms.
• Packaging is prepared for international transport, and logistics under DAP or DDP terms can be coordinated to the destination.
• After commissioning, we support spare parts, technical inquiries and root-cause analysis for operating issues.
• All products carry a 12-month warranty for quality issues caused by raw materials or manufacturing processes.

Information We Use to Configure Your Solution

To prepare a clear configuration and quotation, we need the operating condition and the project target. The following list is the practical basis for our proposal:

• Airflow requirement in m³/h or CFM, plus static pressure or system resistance at the design point.
• Supply voltage, phase, frequency and any speed control signal: fixed speed, 0-10V, PWM or Modbus RTU.
• Ambient conditions: temperature, altitude, humidity, dust load and corrosive exposure.
• Mounting geometry: frame size, orientation, inlet and discharge configuration, and available envelope.
• Target certifications, noise limit, efficiency objective, operating hours and project schedule.
• Expected annual volume, packaging requirements, destination and trade term if you need delivery scope.

With this information, we can match the impeller, motor and control option to the actual machine, avoid oversizing, and confirm the technical file needed for your approval and for factory acceptance testing.

Frequently Asked Questions

What is the difference between your AC, EC and DC centrifugal fan series?

AC centrifugal fans are fixed-speed units with outer rotor motors and ball-bearing construction. EC fans use AC mains input with an integrated EC drive, giving variable speed and communication options such as Modbus RTU. DC fans operate on 24V or 48V supply, support PWM speed control and deliver compact high-static-pressure flow for low-voltage systems.

Can an EC centrifugal fan replace an existing AC fan in our equipment?

Our EC backward-curved fans are designed as retrofit options with standard installation dimensions. We compare the existing AC unit’s airflow, static pressure, mounting layout and connector configuration before confirming suitability, so the replacement is a plug-and-play project rather than a mechanical rework.

What customization do you support for centrifugal fans?

We support OEM and ODM projects with non-standard specifications, voltage, power ratings and special-duty customization. Send your drawing, sample or target performance data, and our engineering team will evaluate the configuration and provide a professional solution with quotation.

What compliance documents do you provide with shipments?

We operate an ISO9001:2015 quality management system. Products carry CCC and CE certification and pass RoHS and UL tests; relevant certificates are available for project review, and pre-shipment inspection reports can be included.

What is the typical MOQ and lead time for a centrifugal fan order?

For standard products, the MOQ is typically 100 pieces. Lead time for regular orders is usually 25 to 30 days, subject to order quantity and customization, and we confirm the exact delivery date before order entry.

What delivery and after-sales support do you provide?

We can arrange international logistics and customs clearance under DAP or DDP terms. After delivery, we provide technical documentation, installation guidance and online support, plus a 12-month warranty covering material and manufacturing defects.
