Why HVAC OEMs Choose EC Centrifugal Fans and External Rotor Solutions

HVAC and cooling OEMs need fan systems that hit airflow/pressure targets, meet noise and efficiency limits, and ship on time. EC centrifugal fans with external rotor motors deliver high efficiency, controllability (0–10V/PWM/Modbus), and compact design—ideal for AHU fans, fresh air systems, filtration, and cabinet cooling. AFL Motor manufactures EC & AC fans with repeatable quality so your project plan stays intact.

Energy-Saving EC Centrifugal Fans (Backward Curved)

Backward curved EC centrifugal fans reduce power consumption while sustaining static pressure for coils and filters. Variable-speed control enables precise duty-point matching, minimizing noise and energy.

Low-Noise EC Axial Fans for Cabinet and Data Center Cooling

Where straight-through airflow and high volume are required, EC axial fans deliver high flow with low acoustic signatures—critical for IT racks, power electronics, and telecom cabinets.

Fast Lead Time for HVAC OEM Projects — 7-Day Samples, 15–20-Day Production

Lead time often controls the entire HVAC integration schedule. AFL Motor structures production around OEM timetables:

• Engineering samples in 7 days to accelerate validation

• Mass production in 15–20 days with transparent scheduling

• Capacity: 1.5 million units/year across Hangzhou & Haining bases (≈45,000 m²)

Production & Quality Enablers for Fast Lead Time

• ≈80% automated lines reduce variation and raise throughput

• ISO9000 quality system and in-process checkpoints protect repeatability

• Precise dynamic balancing stabilizes vibration and noise at scale

Custom EC/AC External Rotor Fan Engineering for AHU and Ventilation

AFL Motor provides custom EC/AC external rotor fans configured to your mechanical envelope and system curve.

Mechanical Interfaces & Mounting (Single/Dual Inlet Blowers)

• Flanges, brackets, and orientation to fit AHU modules and cabinets

• Single inlet for narrow ducts; dual inlet blowers for higher flow in compact spaces

Airflow, Static Pressure & Acoustic Targets

• Fan curves tuned to filter resistance, coil pressure drop, and duct layout

• Noise caps validated via dynamic balancing and acoustic sampling

EC/AC Control, Protection & Integration

• EC control: 0–10V, PWM, Modbus (on request)

• Protection: thermal, over-current, soft start options

• Ingress protection and coatings for dust/corrosion environments

Product Families for HVAC, Industrial Ventilation, and Data Centers

EC Centrifugal Fans (Backward Curved) — Energy-Saving HVAC Fans

High efficiency, variable speed, compact footprint for AHU, fresh air, and filtration systems.

AC Centrifugal Fans — Robust Industrial Ventilation Fans

Proven reliability for factories and process ventilation where AC mains and rugged construction are preferred.

EC & AC Axial Fans — High-Flow Cooling Fans

Straight-through airflow for cabinet cooling, telecom, and data centers with low acoustic impact.

Single & Dual Inlet Blowers — High Static Pressure Fans
