Founded in Germany in 1900, Bole is a century-old brand, a well-known European supplier of ventilation equipment, and one of the world's largest manufacturers of household ventilation products. So far, it has been supported by more than 700 patented technologies, and its products are sold to 92 countries. Bole entered China in 2014 and established a subsidiary: Bole Environmental Systems (Suzhou) Co., Ltd., which is mainly engaged in central heat recovery series ventilation products. Due to the late entry into the market and the main duct fan products, there are not many ventilation fan series for consumers to choose, and most of them belong to the window type.
 
Bole's ventilator fans are sold at a higher price and are aimed at the high-end market. Its strengths lie in its lightweight design, safety performance, and versatility. Bole's products are mostly window-type, with specifications ranging from 4 inches to 6 inches, and the weight is generally controlled at about 1kg, which is exquisite and compact, easy to load and unload, and is incomparable to the products of other brands. At the same time, the motor adopts ball bearings and is mounted on the shock absorber, which is low-noise and durable. In terms of functional structure, Bole's products have functions such as wall and ceiling dual-purpose, detachable mask, two-speed and two-gear, humidity sensing, automatic blinds, etc., which are highly diverse and can meet the application scenarios of different needs. And the most prominent point is that once the fan blade is stuck by a foreign object, the ventilation fan will automatically stop, which is safe and reliable.
 
The four series of Aero Still, Quatro, Auto and Sileo are the main window ventilators of Bole. The Aero Still series belongs to the conventional series of households, inheriting the traditional fan technology of Bole, with a noise of only 25-33dB, and a check valve design to prevent air backflow in the standby state, and also has two installation methods: it can be installed on the wall or on the ceiling, which is flexible and suitable for families with renovation plans, and the price is between 565-785 yuan.
 
In addition to the flexible installation features, the Quatro series can also remove the mask for easy cleaning, but the operating noise is slightly higher than that of the Aero Still, and the price is comparable to it. The third is the Auto series, this ventilation fan is just like its name, with automatic opening and closing of the blinds, suitable for use in the environment with large oil pollution and high humidity, it is recommended that the use of the scene has the necessary consumer purchase, the price is 660-880 yuan. The Sileo series belongs to Bole's high-end products, of which 100T, 100H, and 150 have functions such as delayed shutdown, humidity sensing, and two-speed respectively, which are developed by designers for different scenarios, and the price is between 700-2000 yuan.
 
Compared with Panasonic, the price of Bole's ventilation fans will be 200-300 yuan higher, and even 2-3 times higher than that of Chinese brands. But Bole's low noise and versatility can win the favor of high-quality life seekers for the brand. That's why families with a new home and a budget might want to consider Bole.
