Zhongshan, China – Zhongshan Lichi Motor Co., Ltd. has launched its latest high efficiency blower motor specifically engineered for kitchen range hoods and ventilation systems. The new AC blower motor delivers a verified working air volume of 11.49 m³/min at a maximum static pressure of 432 Pa, tested on the company’s professional Air Flux Testing System. With a total efficiency of 25.04% at the standard operating point, this ventilation motor addresses common user complaints of weak suction, high energy bills, and short service life in residential and commercial exhaust applications.
Verified Performance Data – 432 Pa Static Pressure, 11.49 m³/min Air Volume
Every AC blower motor from Lichi Motor undergoes 100% testing under 220 V / 50 Hz conditions. The model 120 × 72 × 32G achieves a rotation speed range of 730–980 rpm, providing stable airflow for range hoods, industrial fans, and purification systems. Unlike generic motors that lose performance under back pressure, this high efficiency blower motor maintains consistent air delivery thanks to optimized impeller geometry.
Maximum static pressure: 432 Pa – suitable for long duct runs and filter‑heavy hoods
Working air volume: 11.49 m³/min – verified by Air Flux Testing System
Total efficiency at standard point: 25.04% – reduces energy loss compared to conventional ventilation motor designs
For kitchen exhaust systems, a high efficiency blower motor with at least 400 Pa static pressure is recommended when duct length exceeds 3 meters. Lichi Motor’s unit exceeds this threshold by 8%, ensuring strong suction even with two 90° bends.
Low Noise Centrifugal Blower Design – Quiet Operation Below 55 dB(A)
Noise is a top complaint for range hood motors. The new low noise centrifugal blower incorporates dynamically balanced impellers and precision bearings to minimize vibration. Laboratory tests show that this exhaust blower motor operates at noise levels compatible with residential kitchens (estimated ≤55 dB(A) at 1m – contact Lichi for exact test reports).
The low noise centrifugal blower construction also extends lifespan. Advanced cooling channels inside the exhaust blower motor reduce winding temperature rise by approximately 12 °C compared to enclosed designs. Lower thermal stress means the AC blower motor can run continuously for 8–10 hours in commercial restaurant hoods without performance degradation.
Selection tip: For hotel kitchens or open‑plan apartments, choose a low noise centrifugal blower with vibration‑dampening mounts – standard on all Lichi Motor units.
25.04% Efficiency and Stable Operation – Reducing Energy Waste
A typical ventilation motor in the market operates at 18–21% total efficiency. Lichi Motor’s high efficiency blower motor achieves 25.04% at the rated point, translating to 15–20% less electricity consumption for the same air volume. When installed in a range hood running 6 hours daily, this AC blower motor can save approximately 80–100 kWh per year (actual savings depend on duty cycle).
The exhaust blower motor also maintains speed stability under fluctuating voltage (±10%). Each unit passes vibration, balance, and thermal resistance tests before shipping. For ventilation fan manufacturers, switching to this high efficiency blower motor means lower warranty claims due to overheating or airflow drop‑off.
Supply Capacity 30,000 Units per Month – 15‑Day Delivery
Lichi Motor’s factory in Zhongshan produces up to 30,000 pieces of AC blower motor per month. Standard delivery time is 15 days for batch orders. The ventilation motor line includes automatic winding machines and real‑time quality monitoring, ensuring consistent performance across large volumes.
Customization options for the high efficiency blower motor include:
Voltage: 110 V / 220 V (50/60 Hz)
Impeller diameter and housing materials
Airflow direction (clockwise / counter‑clockwise)
Mounting brackets, plug types, and OEM labeling
For distributors, the low noise centrifugal blower can be adapted to various exhaust systems – from wall‑mounted range hoods to in‑line ventilation fans.
Selection Guide – Which Blower Motor for Your Application?
| Application | Recommended Motor | Why |
|---|---|---|
| Residential range hood (duct ≤3m) | High efficiency blower motor (432 Pa) | Overcomes filter resistance, low noise |
| Commercial kitchen exhaust | Exhaust blower motor with reinforced bearings | Continuous operation, 25.04% efficiency |
| Bathroom or attic ventilation fan | Low noise centrifugal blower | Quiet operation, long life |
| HVAC make‑up air unit | AC blower motor (custom voltage) | Stable speed under variable loads |
When selecting a ventilation motor, always check three parameters: static pressure at desired air volume, efficiency percentage, and bearing type. Lichi Motor provides full test reports for each high efficiency blower motor batch, eliminating guesswork for OEM engineers.
