7 Blades: The 7 streamlined blades are more powerful compared to the 4 or 5 blades exhaust fan on the market. The 201 stainless steel material of these blades can also be rust-resistant, corrosion-resistant, and easy to clean. Waterproof: The good sealing of this exhaust fan can effectively block water vapor and water droplets. The all-iron housing also makes the exhaust fan more waterproof. The good waterproof effect can ensure that the exhaust fan is safer to use and has a longer service life. Low Noise: The built-in copper motor is lightweight and has low vibration. Therefore the exhaust fan runs more stably with a noise level of no more than 65dB. One-way Valve Design: The exhaust fan is a one-way valve design, which will only exclude the exhaust gas from the inside to the outside when running, so as not to reverse the suction. Four screws hold the mesh of the exhaust fan in place, which can prevent shock and shake. This makes the exhaust fan more stable. High Flow Rate: This exhaust fan can exhaust 2650m³ of air per hour. This flow rate is large enough to exhaust the produced waste air as quickly as possible. The copper motor makes this exhaust fan rotate up to 2800r/min. This makes the exhaust fan operate faster and its work efficiency will be improved.
