Choosing a kitchen extractor blower comes down to three things: enough airflow to clear grease and steam quickly, enough static pressure to push through grease filters and ductwork, and a motor that stays quiet and efficient. SUNXFAN’s dual-inlet centrifugal blowers are engineered specifically for this job.
Why dual-inlet centrifugal blowers for range hoods
- ~40% more airflow at the same impeller diameter and speed than single-inlet fans — you get more extraction without a bigger hood.
- High static pressure to overcome grease filters, elbows and fire dampers in long duct runs.
- 8–12 dB(A) lower noise than traditional single-inlet fans — critical for open kitchens.
- EC motors hold >85% efficiency at partial load, for up to 70% energy savings vs AC.
How to choose the right model
- Airflow (m³/h) — match the hood width and cooking intensity. Residential hoods typically need 600–900 m³/h; commercial and island hoods 1000–1700 m³/h.
- Voltage — pick by market: 24V/48V/310V DC for battery or central-DC designs, 115V AC for North America, 230V AC for Europe/global.
- Speed control — 0-10V/PWM or 0-5V/0-6.5V for sensor-driven “on-demand ventilation”; 3/4-speed for simple push-button control.
- Noise & efficiency — EC models are quieter and more efficient than AC at the same airflow.

|---|---|---|---|---|---|
| 24V battery / portable hood | SF146A-D092A6-02 | 24 V DC | 720 m³/h | 80 W | 52±2 dB(A) |
| 48V built-in hood | SF146D-D092A8-01 | 48 V DC | 1020 m³/h | 165 W | 60 dB(A) |
| 310V central-DC system | SF146A-D092A0-02 | 310 V DC | 1080 m³/h | 180 W | 64±1 dB(A) |
| North America 115V | SF146A-E092A1-01 | 115 V AC | 860 m³/h | 120 W | 60±1 dB(A) |
| North America 115V (higher CFM) | SF146D-E092A1-02 | 115 V AC | 1050 m³/h | 165 W | 62±1 dB(A) |
| Europe 230V standard | SF146A-E092A3-02 | 230 V AC | 1080 m³/h | 180 W | 64±1 dB(A) |

| High-CFM / island hood | SF160D-E092B3-42 | 230 V AC | 1690 m³/h | 240 W | 60±2 dB(A) |
| Universal voltage (110–230V) | SF235A-E092B3-F2 | 110-230 V AC | 1650 m³/h | 240 W | 62 dB(A) |
Bottom Line
For most residential range hoods, the SF146A-E092A3-02 (230 V AC, 1080 m³/h) hits the airflow/price/noise sweet spot for European and global markets, while SF146A-E092A1-01 (115 V AC, 860 m³/h) covers North America. For high-CFM island hoods and commercial extraction, step up to the SF160D-E092B3-42 (1690 m³/h) or the universal-voltage SF235A-E092B3-F2.
