Roof Ventilator

Fluorine Carbon Polyester Coating Aluminum Alloy RoofTurbo Ventilator Model: 300/ 500/ 600 Materials: Adopting 3005# aluminum alloy as base material, outer layer coating fluorine carbon polyester greater than 20 µm; Japanese NSK bearing; fireproofing reinforced nylon support or metal support; rivet to connect. Benefits: Light weight, high revolving speed, strong corrosion resistance, high air exhausting efficiency, clean and smooth, uniform color, and easy maintenance. Working Condition: Temperature difference between indoor and outdoor is 0.45, It begins to revolve at the wind speed of 0.12m/ s. Roofing Angle: Applied in different roofing in the scope of 0-22.5°oblique angle. Warranty: 15 years Applicable scope: Industrial workshop, commercial and civil housing. Major Fittings of Ventilators: Axis and BearingTianrui ventilator adopts Japanese NSK airtight axle bearing, self-lubricating and anti-wearable. Number C45 steel as major axis has strong anti-corrosion. Outside of major axis is packed by fireproofing nylon plastic. Support Tianrui turbine ventilator adopts fireproofing reinforced nylon plastic as support (or metal support) with light weight. It not only has strength of metal but also tenacity of plastic as well as fine recovering performance. Compared with metal support, ventilator made from this kind of support won't be out of shape. Blade Wave blade is designed according to accurate Fluid Mechanics Principle, increasing the contact area and angle of blade and wind. Even under breeze, ventilator can have greater revolving power so as to keep the wind in all direction from blowing backward into wind course. Meanwhile, revolving speed of turbine heads can be increased by wind in all direction, playing an important role of waterproofing, snow proofing and air exhausting. Adopting wave blade, the mechanic strength can be greatly increased, capacity to bear pressure is t best of all similar products.
