Brand: Okryain Electric Fan Design: Ventilation Fan Power Source: Power Cord Style: Classic Product Dimensions: 9D x 16.5W x 17H cm Material: ABS 【High-Density Insect Screen & Protective Netting】 The ventilation fan uses ABS plastic material, which is not easily deformed and has excellent wear resistance, corrosion resistance, and durability. The fan is equipped with an ABS protective net and a high-density insect screen in front to prevent insects and other foreign objects from entering during the high-speed operation of the blades, as well as preventing injuries from contact. 【Overheat Protection & Easy Operation】 The ventilation fan is equipped with overheat protection, allowing for safe use. A switch is attached to the power cord for convenient operation. "Energy Saving & Low Noise" The ventilation fan uses a sealed pure copper bearing motor, which generates less heat and reduces the friction coefficient compared to ordinary motors, saving power and ventilating more efficiently. It only costs 3 yen for electricity even after 8 hours of continuous operation! The fan blades are designed according to the principles of fluid dynamics, making the airflow smoother and reducing operating noise. 【Wide Range of Applications & Easy Installation】 Suitable for places that require ventilation, such as bathrooms, living rooms, kitchens, and warehouses. It is ideal as a ventilation fan for campers, warehouses, underfloor ventilation, bathroom ventilation, dog houses, and cat litter box rooms. Installation is easy and DIY is possible. ★Note: For scenes such as attics, BBQs, and DIY painting, we recommend industrial ventilation fans/duct fans with stronger airflow and suction. 【30-Day Free Returns for Peace of Mind】 We want our customers to try OOPPEN products with peace of mind, so we offer returns and refunds within 30 days of purchase.
