Unpowered ventilators are also called roof ventilators, natural ventilators, power-free ventilators, and turbine ventilators. They are ventilation equipment installed on both sides of the roof ridge at the top of an industrial factory. They can replenish enough fresh outdoor air 24 hours a day without power to promote the factory building. Air circulation and convection improve the working environment and ensure the health of employees. Improved work quality and work efficiency, creating more production benefits for the enterprise!
Roof fan Working principle of unpowered ventilator:
- It uses the principle of natural air convection to accelerate and transform air flow in any parallel direction into vertical air flow from bottom to top.
- It is a device that uses the chimney effect produced by the combination of buildings and equipment to achieve indoor and outdoor ventilation.
The scope of application is ventilation in large factories, warehouses, venues, livestock farms, commercial places, high-rise buildings, residential buildings, etc.
The characteristics of the fan are zero-cost operation for 24 hours without human operation, light weight, green and environmentally friendly, long life without noise, easy and quick installation, wide applicability, unique round appearance (the Tai Chi principle resolves the force of horizontal push) and support structure. Ensure that the turbine can withstand typhoon attacks. Using a unique variable angle pipe diameter, it can be directly installed on all kinds of industrial plant light steel structure profiled plate roofs and concrete roofs as long as the inclination angle is 0~22.5, and other slopes and accessories can also be installed.
The advantages of the Roof fan are:
- Strong and corrosion-resistant, with a 10-year quality guarantee. The high-quality body can withstand wind and rain for a long time, and can resist the erosion of indoor corrosive gases. The excellent fully sealed low-resistance bearings are durable and permanently lubricated. No maintenance required. The casing is made of aluminum alloy and is filled with thermal insulation material to achieve better heat and sound insulation effects.
- The ventilator adopts fully enclosed bearings and requires no lubrication. C45 steel is used as the main shaft and has strong corrosion resistance. The structure design is reasonable, there are no power components, and all spare parts have no possibility of rust.
- The wavy blades are designed based on precise fluid mechanics principles, which increases the contact and angle between the fan blades and the wind. It can also obtain greater rotational force in the breeze and avoid wind from all directions pouring into the air duct. phenomenon, and uses the wind from all directions to accelerate the rotation speed of the turbine head, fully playing the role of rainproof, snowproof and wind exhaust. Due to the corrugated shape, the mechanical strength is greatly enhanced, and it has the best pressure-bearing capacity among similar products!
- Insect-proof and dust-proof: There are insect-proof and dust-proof nets on the ventilation channels.
Many industrial plants, especially those built with colored steel plates, have poor heat dissipation conditions and are extremely hot in summer, resulting in low work efficiency and reduced product quality. The addition of unpowered roof fans can effectively improve indoor air quality, provide a comfortable working environment, and increase work efficiency. In many industries, due to the special nature of production, air pollution in the factory is caused. Not only is the environmental quality low, but in the long run, the health of employees will definitely be harmed. However, the installation of unpowered roof fans improves indoor ventilation and can effectively protect employee health. In many fire accidents, people are often choked by thick smoke. If a non-powered roof fan is installed, it can quickly discharge a large amount of thick smoke and give people more room to escape, so it is also a safety device.
