TOPRISE takes 3005# aluminum alloy as base material, with its surface being treated with anti- oxygenizedfilm, on which sprays 20um fluorocarbon coating. At present, fluorocarbon coating aluminum alloy ventilatoris certainly the lightest in weight. Thus, the pressure on the bearings is smaller and revolving ability is naturallybetter than that made of other materials. Fluorocarbon coating aluminum alloy ventilators provide superioiweather resistance, wearability, longer service life, light weight and higher sensitivity than other materialsFluorocarbon coating aluminum alloy ventilator is the ideal choice for your buildings.
There are different quality levels of stainless steel. Under normalusage environments, the performance of corrosion resistance of304 or 316 stainless steel is good enough compared with otherstainless steel.
However, confronted with some badly corrosive and terrible airatmosphere, such as coastal workshops, pickling workshops andso on, stainless steel ventilators are unable to meet the requirements.lf we use higher quality of stainless steel, the cost will be increasedgreatly. And mill finish aluminum alloy is easy to be oxidized andcorroded.
TOPRISE has been leading in improving the performance andservice life of ventilators. TOPRISE fluorocarbon coating aluminumalloy ventilators solve the problems of corrosion, making it possibleto be used in high corrosive environments.
NYLON SUPPORT
TOPRISE Roof Ventilator adopts fire rated nylonsupport. It is light in weight, has metal strength,pastic tenacity and better recovering performance.
NSK BEARING
Japanese NSK totally enclosed and freelubricated bearing.C45 Steel shaft withstrong abrasive resistance. The shaft isenclosed by fire rated nylon material.
VARIPITCH-ADJUSTABLE NECK
TOPRISE use unique varipitch which can be installedto any roofs between the oblique angle of 0-22.5“or 0°-30” It is so easy and fast to install so as toreduce instalation cost.
RAIN- PROOF DOUBLECURVED BLADE DESIGN
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.
O UNIQUE INNER FAN
TOPRISE unique light weight aluminum alloyinner fan design increases exhaust capacityof ventilator effectively. (Inner fan could beadded depending on your demand. )
O METAL SUPPORT
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 CONNECTING PIECESALUMINUM RIVETS，FASTENING SCREWS
Stainless steel bearing holders are used for fixingbearing.
