About these itemsHigh - Performance Airflow: These exhaust fans, available in 6 - inch, 8 - inch, and 10 - inch sizes, deliver strong airflow. The 6 - inch fan provides 308 CFM, the 8 - inch fan offers 576 CFM, and the 10 - inch fan gives 988 CFM, ensuring fast smoke and air circulation in kitchens, workshops, and other areas.Energy - Efficient Operation: All fans operate with relatively low power consumption. The 6 - inch fan uses 27W, the 8 - inch fan uses 55W, and the 10 - inch fan uses 64W, providing effective ventilation while being energy - conscious.User - Friendly Operation: Each kitchen exhaust fan features a convenient on/off switch. This allows for easy control, enabling quick ventilation without the need to unplug the device, making daily use straightforward.Durable Construction: Constructed with a high - quality steel body, these wall - mount vent fans are built to last. They can withstand the rigors of daily use in high - frequency areas like kitchens, garages, and attics.Backdraft Protection: Equipped with a backdraft damper, the fans automatically close when turned off. This helps prevent the backflow of outside air, particles, and cold drafts, maintaining a more comfortable indoor environment.Key DifferencesSize and Airflow: The most obvious difference is the size of the fans. The 6 - inch fan (HDB - 150C) has the smallest dimensions (7.48 x 7.48 x 5.51 in) and the lowest airflow (308 CFM). The 8 - inch fan (HDB - 200C) is larger (9.84 x 9.84 x 5.91 in) with a higher airflow of 576 CFM. The 10 - inch fan (HDB - 250C) is the largest (11.81 x 11.81 x 6.30 in) and offers the highest airflow of 988 CFM.Power Consumption and RPM: The power consumption increases with the size of the fan. The 6 - inch fan uses 27W and has an RPM of 3065. The 8 - inch fan uses 55W with an RPM of 2814, and the 10 - inch fan uses 64W with an RPM of 2377. As the fan size increases, the RPM generally decreases while the power and airflow increase.Noise Level and Weight: The noise level also varies with size. The 6 - inch fan has a noise level of â¤50dB and weighs 2.89 lbs. The 8 - inch fan has a noise level of â¤60dB and weighs 4.01 lbs. The 10 - inch fan has a noise level of â¤64dB and weighs 4.85 lbs. Larger fans tend to produce slightly more noise and are heavier.SpecificationsHDB - 150C (6 - inch fan)Item Model Number: HDB - 150CPower: 27WRated Voltage: 120V, 60HzRPM: 3065 RPMAir Speed: 4.1 m/sAirflow: 308 CFMNoise Level: â¤50dBNet Weight: 2.89 lbs / 1.31 kgProduct Size: 7.48 x 7.48 x 5.51 in / 190 x 190 x 140 mmHDB - 200C (8 - inch fan)Item Model Number: HDB - 200CPower: 55WRated Voltage: 120V, 60HzRPM: 2814 RPMAir Speed: 5.9 m/sAirflow: 576 CFMNoise Level: â¤60dBNet Weight: 4.01 lbs / 1.82 kgProduct Size: 9.84 x 9.84 x 5.91 in / 250 x 250 x 150 mmHDB - 250C (10 - inch fan)Item Model Number: HDB - 250CPower: 64WRated Voltage: 120V, 60HzRPM: 2377 RPMAir Speed: 5.8 m/sAirflow: 988 CFMNoise Level: â¤64dBNet Weight: 4.85 lbs / 2.2 kgProduct Size: 11.81 x 11.81 x 6.30 in / 300 x 300 x 160 mmPackage ContentFor all models (HDB - 150C, HDB - 200C, HDB - 250C)1 x Wall Mount Vent Fan4 x Screws4 x Plastic Expansion Screws1 x User Manual
