roof ventilatior Aipukeji880

1 Non-power natural ventilation fans are favored by many businesses for their energy-saving and environmental protection, the 880-type fan with its large-caliber breathing ability is especially favored by chemical plastic and other special Industries.
2 Its high-quality body can withstand long-time wind and rain; resist the erosion of corrosive gases indoors. It can be durable eternal lubricant and no maintenance for its excellent low resistance sealed bearings.
3 Wave-shaped leaves is designed based on the accurate hydrodynamics principle, increased the interface and angle between the fan and wind. It also can get a greater rotational force in the breeze, avoiding the wind of all direction into the air duct, accelerating the rotation speed of the turbines with all direction wind which takes an effect of waterproof, anti-snow and ventilation. Because of its wave shape, the mechanical strength greatly increased, the capacity to withstand pressure is best of the similar products.
