Okryain Ventilation Fan 200mm, Household Industrial Ventilation Fan, Air Volume 980m³/h, Mid-Mount Duct Fan, Commercial Ventilation Fan, Large Air Volume, Powerful, Duct Fan, Recessed Type, for Warehouse/Toilet/Kitchen Ventilation and Exhaust (200mm - White) 【Household Industrial Ventilation Fan】Fan Diameter: 8inch/200mm, Color: White, Air Volume: 980m³/h, Air Pressure: 105Pa, Power Consumption: 53.5W, Rotation Speed: 2650r/min, Noise Level: 50dB, Voltage: 100v-120v, Frequency: 50Hz/60Hz, Outlet: 3-pin. ★Note 1: Air Pressure: Parameter for the distance the fan can blow air. For painting work or large space ventilation, we recommend the GF-150P or low-noise duct fans with stronger air pressure. ★Note 2: Not applicable in places where the voltage is less than 100v, the motor may burn out, and the fan may not rotate properly. 【Large Air Volume & Injury Prevention Edge Guard】The industrial ventilation fan uses sturdy iron material and the latest spraying technology, making it wear-resistant, high-temperature oxidation-resistant, and durable. Equipped with a powerful induction motor and double ball bearings, the air volume reaches 980m³/h, providing stable and powerful airflow. In addition, the ventilation fan is equipped with a transparent edge guard, which is smooth and prevents injuries, making it safe to carry. 【High-Density Protective Net & Backflow Prevention Damper】A high-density metal protective net is used in front of the ventilation fan, which not only prevents foreign objects from being caught during the high-speed operation of the blades but also prevents injuries from physical contact. The iron protective net has rust-prevention treatment with rust-proof coating. However, do not place it in a humid place like a bathroom for a long time. If you do not perform regular maintenance, it may rust. A backflow prevention damper is attached to the back, which strongly prevents the entry of dust, insects, cotton, rainwater, etc., and prevents outdoor air from flowing back. 【Powerful Motor & Easy Maintenance】The ventilation fan uses a powerful induction motor. Compared to ordinary motors, the upgraded motor reduces the friction coefficient, effectively saves power, and ventilates more efficiently. In addition, by loosening the screws at the four corners of the ventilation fan, it is easy to disassemble the protective net, internal blades, motor, etc. Dust and oil stains can be cleaned regularly. This is helpful for extending the ventilation effect and the product's service life.
