high quality natural roof ventilator in spherical shape and straight vanes shape for residential commercial and industrial buildings.
lt is driven by natural wind and temperature difference between indoor and outdoor so do not need any power. lt's energy saving and environmental protection, and so it can save electricity bill
it is anti-corrosive, rain-proof. It is efficient exhausting and low noise.
it can keep fresh air flowing to reduce temperature in buildings and to provide a better working environment,
can be powder coated with different colors as per clients requirements.
spherical shape vent:
we provide two kinds of fluorocarbon coated aluminum alloy and SS304 , fluorocarbon coated aluminum alloy one is hot sale, it is lighter than stainless steel, and the light fan helps to increase the rotate speed, and exhaust more volume. It is 3005# aluminum alloy as base material, its surface being treated with anti- oxidative film, on which sprays 20um fluorocarbon coating. so it is more ant-corrosive than stainless steel and Mill Finished ALU alloy. we are leading factory in improving service life. Our fluorocarbon coating aluminum alloy ventilators solve the problems of corrosion, it now can be used in high corrosive environments. We use NSK stainless steel bearings.
The spherical shape increases the area of contact between the blade and the wind. So,Even breeze,the ventilator can also have a large rotation capacity, at the same time, it can be waterproof, snow proof. spherical shape also can improve the pressure capacity.
We have 150mm,200mm,250, 300mm, 500mm, 600mm
Straight Vanes Ventilator:
it is vertical vanes, which can increase larger exhaust volum than spherical shape vent., Less ventilators are needed for your buildings so that cost can be reduced. We use anodized aluminum alloy material which is corrosion resistant so service life is longer.it is rain proof and dust proof, it's specially designed for commercial and industrial buildings.
We have 600mm, 700mm and 900mm
in order to meet requirements of clients in cold areas, TOPRISE specially research 900mm ventilator with damper. Clients may close it in winter if needed.

Japanese NSK totally enclosed and freelubricated bearing. C45 Steel shaft withstrong abrasive resistance. The shaft isenclosed by fire rated nylon material.
Several stiffeners are made to makethe ventilator stronger.
TOPRISE Roof Ventilator adopts fire rated nylonsupport. lt is light in weight, has metal strength,plastic tenacity and better recovering performance
TOPRISE use unique varipitch which can be installedto any roofs between the oblique angle of 0°-22.5or 0°-30°. lt is so easy and fast to install so as toreduce installation cost.
Wave-shaped blades are designed on the principleof fluid dynamics, which increases the contact areabetween blades and wind. Even under breeze.ventilator can have greater revolving ability so asto keep the wind from all directions blowing backwardinto the air channel . Meanwhile, revolving speed ofturbine head can be increased by wind in all directions.playing an important role in water proofing, snowproofing and air venting. Due to the wave-shapeddesign, the mechanical strength of ventilator can beincreased,and capacity to bear pressure reachesthe best of all the similar products.
TOPRISE unique light weight aluminum alloyinner fan design increases exhaust capacityof ventilator effectively. (lnner fan could beadded depending on your demand.)
There are grooves in the middle of supportlegs increasing its strength. We use tightenpiece to fix the support securely instead ofwelding to avoid rusting in welding places
Stainless steel bearing holders are used for fixingbearing.
