DC Axial Fan Manufacturers

Hangzhou Beron Motor Co., Ltd. is a DC Axial Fan manufacturer serving OEM equipment builders, distributors and project teams worldwide. Our DC axial fans use brushless motors for improved speed control and significantly reduced power consumption, and the BERON-MOTOR DC series is the preferred solution for telecommunications, medical equipment and automotive cooling.

The range is part of our broader Axial Fan family, which also includes AC Axial Fan and EC Axial Fan models. DC versions fit naturally when a DC supply already exists in the equipment, because they avoid a separate line-power conversion stage while providing the speed control that fixed-speed AC fans cannot deliver. We manufacture the range from our production and R&D centers in Hangzhou and Huzhou, with a 6,000 m² factory area and more than 16 years of fan and micro-motor experience since the company was founded in 2010.

Our DC Axial Fan Range

We currently offer two platform positions in this category. Both use brushless DC motors, and both are available through standard ordering or OEM/ODM development.

Where DC sits in the Axial Fan family

• AC Axial Fan — fixed-speed operation direct from mains voltage; the simplest choice for continuous duty where speed control is not required.
• EC Axial Fan — AC input combined with an integrated controller and brushless DC motor; used when line-powered equipment needs controllable speed plus networked communication such as Modbus.
• DC Axial Fan (this range) — direct connection to a system DC bus; the best fit for electronics, telecom, vehicle and battery-powered equipment where efficiency and speed control are priorities.

Application Fit and System Integration

Our DC axial fans are used across machinery, refrigeration, HVAC, household appliances, power electronics, IT communication and new energy storage. The table below shows how we map applications to the range and what we need to confirm the working point.

Construction and Engineering Value

The DC series is designed around three priorities: predictable airflow, long service life and quiet operation.

• Brushless motor drive — electronic commutation replaces brushes, cutting power consumption and removing a major wear component.
• High-quality ball bearings — selected for more than 50,000 hours of continuous operation in normal conditions.
• Optimized impeller design — fan blades and housing geometry are tuned to deliver maximum airflow with minimal noise.
• Simple mechanical construction — fewer moving parts and stable assembly reduce failure points, which is why the 24V platform emphasizes reliable run-time.

Our engineering team holds dozens of patents in fan structure, fluid dynamics, motor design and control circuits. That technical base supports product qualification, application adjustments and root-cause analysis when a customer encounters a system-level airflow issue.

Critical Specifications and Performance

Specification work starts from the system working point, not from a generic model. The main parameters we define with you are the required airflow at a given static pressure, the available voltage and the acceptable noise level.

• Voltage versions: 24V DC and 48V DC standard platforms.
• Speed control: the 48V model provides convenient speed adjustment for variable cooling demand; the 24V model emphasizes stable fixed operation with low noise.
• Starting voltage and rated voltage: we confirm the start-up voltage behaviour against the real supply in the equipment so that the fan starts reliably under load.
• Duty cycle: designed for continuous operation in free-air and restricted enclosure applications.

If the duty point falls outside the standard models, we treat it as an OEM/ODM request and evaluate voltage, power rating, frame size and blade geometry against the project requirements.

Configuration, Controls and Automation Integration

DC axial fans integrate easily with electronic systems because speed control is part of the motor platform. For line integration we clarify the control method, connection scheme and feedback signal before finalizing the configuration.

• Speed adjustment via the fan interface or system controller, matched to the required airflow profile.
• Feedback options so the system can detect fan status and alarm conditions.
• Custom wire length, connector type, terminal arrangement and mounting holes for drop-in assembly.
• Non-standard voltage and power ratings for special-duty applications.

Our engineering and selection service covers operating-condition analysis, fan selection and technical consulting before the order, followed by technical coordination during production and commissioning support after delivery.

Quality Assurance, Testing and Compliance

We validate DC axial fan performance in our own laboratories rather than relying only on calculation. The Hangzhou and Huzhou centers include a wind tunnel laboratory, noise laboratory, comprehensive motor performance laboratory and aging laboratory covering the main acceptance criteria for airflow, acoustic behavior, motor characteristics and long-run reliability.

• ISO9001:2015 quality management system certification.
• Products carry CE certification and CCC certification, and have passed RoHS and UL testing.
• IP55 rating tests are applied where the fan is exposed to dust or water spray.
• Pre-shipment inspection, factory acceptance testing and third-party inspection support are available.

Installation, Maintenance and Project Support

Every fan is delivered with the technical documentation needed for mechanical installation, electrical connection and commissioning. We specify airflow direction, mounting torque and the recommended clearance around the fan so that the working point is reached in the final enclosure.

Maintenance is limited mainly to periodic cleaning of the impeller and inlet guard; the sealed bearing system is designed for continuous long service. Our after-sales support includes operation guidance, root-cause analysis support and a 12-month warranty covering material and manufacturing defects. For series orders we coordinate professional packaging, international logistics and certification compliance.

DC Axial Fan FAQ

What voltage options are available for DC axial fans?

Our standard platforms are 24V DC and 48V DC. The 24V model is aimed at HVAC ventilation and compact enclosure cooling, while the 48V model suits telecom, industrial and energy-storage applications. For series projects we evaluate custom voltages and power ratings under our OEM/ODM service.

What operating life can we expect from the DC series?

The fans use high-quality ball bearings designed for more than 50,000 hours of continuous operation. Actual life depends on ambient temperature, duty cycle and mounting conditions; our aging laboratory test data helps confirm suitability for your application before series production.

Can BERON customize DC axial fans for an OEM project?

Yes. OEM and ODM are core services. Provide detailed specifications, drawings or samples, and our engineering team will evaluate them and return a professional solution and quotation covering mechanical, electrical and control requirements.

What is the MOQ?

For standard products, the MOQ is typically 100 pieces. For customized products, the MOQ depends on the process and requirements, and we confirm it in the quotation.

Do you provide samples before series production?

Yes. Samples are available against a sample fee and express delivery charge; the sample fee is deducted once a formal order is placed. Standard samples ship within 3-5 days, and regular production is normally 25-30 days.

How do we select between AC, EC and DC axial fans?

Choose DC axial fans when the equipment already has a DC bus, such as telecom base stations, vehicle systems, battery-powered devices and power electronics. Choose AC axial fans for simple fixed-speed mains operation. Choose EC axial fans when line-powered equipment needs integrated speed control and networked communication. We confirm the right family from your working point, supply voltage and control requirements.
