EC Duct Fan Manufacturers

The EC Duct Fan manufacturer range from Hangzhou Beron Motor Co., Ltd. combines AC line input with electronically commutated motor technology, giving plant engineers, machine builders and HVAC contractors a duct-mounted fan with variable speed, low noise and lower running cost than a fixed-speed AC impeller unit.

We design, test and assemble at two production and R&D centers in Hangzhou and Huzhou, China, with wind tunnel laboratories, noise laboratories, motor performance laboratories and aging laboratories supporting development and verification. The EC duct fan is part of the wider Duct Fan family, supplied alongside AC Duct Fan models when a project requires a simpler fixed-speed or stepped-speed alternative.

What the EC duct fan delivers

The EC duct fan represents the next generation of inline ventilation technology. Instead of running a single-speed AC motor and then throttling the airflow, the integrated electronic controller drives the motor at exactly the speed the system needs. In typical operating ranges this approach reduces power consumption by up to 70% compared with standard AC models, while the same fan envelope can deliver higher pressure and airflow when the duty demands it.

Stepless speed regulation is standard. Built-in or external controllers support PWM or 0-10V signals, so the fan can be tuned to the exact airflow required rather than cycling between fixed speeds. Optimized motor technology also reduces acoustic vibration, making the EC duct fan suitable for noise-sensitive environments such as offices, laboratories and planting rooms. For distributors, one EC model can cover the performance range of several AC models, reducing inventory pressure while still meeting varied project requirements.

Application fit across our customer base

Beron Motor supplies EC duct fans for OEM production runs and project-based procurement across HVAC, refrigeration, power electronics, IT communication and new energy storage. The fans install directly into round or rectangular duct runs, providing extract ventilation, fresh-air supply, pressure assist or temperature-controlled airflow without reworking the duct layout.

• Air conditioning and ventilation: variable-air-volume systems, heat recovery units and balanced ventilation where airflow must follow demand.
• Refrigerated and cold chain: evaporator units, cold rooms and display cabinets where motor heat and running cost are critical.
• Offices, laboratories and planting rooms: continuous low-speed operation with low sound levels instead of on/off cycling.
• Power electronics, IT and energy storage: ducted cooling paths with controlled airflow and remote fault signaling.
• Machinery and equipment: compact ducted cooling with adapted mounting orientation, terminal position and electrical interface.

Control and automation integration

A duct fan only delivers its efficiency advantage when the control system can vary the speed. Our EC duct fans accept PWM or 0-10V analog signals directly, so they can be wired to a thermostat, humidity sensor, CO2 transducer, PLC analog output or a manual potentiometer. Stepless regulation lets the fan follow the demand curve and hold the required airflow as filters load or duct resistance changes.

For building management systems and industrial networks, we offer EC duct fans with Modbus RTU communication for intelligent networked control and fault diagnosis. The fan reports running status and fault information to the controller, allowing maintenance teams to act before a minor issue becomes an outage. When the application needs a compact wheel format rather than an inline duct unit, our EC Centrifugal Fan range is the corresponding option.

Configuration options and project engineering

We configure each EC duct fan around the installation and the electrical interface, not just the airflow value. Our engineers review duct size and connection, mounting orientation, access to the terminal box, ambient temperature around the motor and the supply characteristics available on site. Non-standard voltages, power ratings and special-duty customization are handled in the same process, supported by OEM/ODM services for branded products and customer-specific packaging.

• Controller arrangement: built-in, external or interface-only variants to match the system architecture.
• Speed input selection: PWM or 0-10V, with Modbus RTU when the fan must join a control network.
• Terminal position, cable entry and connector details for tight plant spaces.
• Supply voltage and frequency matched to the destination market and site conditions.
• Custom nameplates, branding, documentation and packaging for OEM programs.

Installation, commissioning and service

Delivery includes the technical documentation and operating instructions needed for installation and commissioning. For standard products, samples normally ship within 3-5 days and regular production runs take 25-30 days depending on quantity and configuration; we confirm the delivery date at order review. Packaging is arranged for export transport, and our team can coordinate international logistics and destination-country customs clearance under the agreed trade terms.

All products carry a 12-month warranty covering defects in materials and manufacturing, with online installation guidance and optional engineer visits for large orders. Because the EC motor has no brushes to replace, scheduled maintenance is limited to cleaning the impeller and checking controller connections, which keeps lifecycle cost low.

Quality, testing and compliance

As an EC Duct Fan supplier for OEMs and distributors, we keep development and quality control in-house. The Hangzhou and Huzhou centers include wind tunnel laboratories, noise laboratories, comprehensive motor performance laboratories and aging laboratories, and our patents span fan structure, fluid, motor and control circuits. Production runs under an ISO9001:2015 quality management system, and our EC duct fans carry CCC and CE certification and have passed RoHS and UL tests.

Before shipment we verify appearance, nameplate data, assembly integrity, accessories and packaging, and coordinate performance verification or factory acceptance tests where the project requires them. Certification documents are provided as part of the order documentation.

Information we use to configure your solution

To prepare a configuration and a complete quotation, our engineers need the operating point and the control context rather than a model number alone. The table below summarizes the project information that defines the correct EC duct fan variant.

Send us the operating conditions, available space and control architecture. Our proposal will confirm the model, controller option, compliance documentation and inspection scope so the order can move directly to production.

Frequently asked questions about EC duct fans

What energy saving can we expect from an EC duct fan compared with an AC model?

Depending on the operating point and duty profile, the EC duct fan can reduce power consumption by up to 70% compared with standard AC models. The saving is largest in partial-load operation, because the EC motor maintains efficiency at reduced speed while an AC fan running at fixed speed wastes energy when airflow is throttled.

Can your EC duct fan be integrated into our BMS or PLC system?

Yes. The fans accept PWM or 0-10V speed signals, and we offer Modbus RTU as an option for networked control and fault diagnosis. We match the controller type to the interface on your project and confirm the wiring scheme in the proposal.

Do you support OEM/ODM configurations for branded duct fans?

OEM and ODM are core services. Provide the performance point, duct interface, control requirement, drawing or sample, and our engineering team will evaluate feasibility and return a solution with quotation. Non-standard voltages, power ratings and special-duty customization follow the same process.

What quality and compliance evidence is available for your EC duct fans?

Our production facilities operate under ISO9001:2015, and the EC duct fan range carries CCC and CE certification and has passed RoHS and UL tests. We can include performance verification, factory acceptance testing and third-party inspection in the order scope.

What are the standard lead time and warranty?

For standard products, samples normally ship within 3-5 days and regular orders within 25-30 days depending on quantity and configuration. All products carry a 12-month warranty against defects in materials and manufacturing, with online installation guidance and optional on-site support for large orders.
