bigbird Roof Turbine Ventilators

Commercial & Industrial - 500mm

Our Big Bird is manufactured from imported Fluorocarbon Polyester Coating Aluminum Alloy and is super light. The lightweight construction allows for unhindered spinning for effective and efficient ventilation.

We use a Unique soaker sheet, to prevent leaks to most roof types. A specially machine-form pressed Trimmer for the underside of the Turbine protects your roof insulation

Fluorocarbon Polyester Aluminium Turbine Ventilators

Our turbine ventilators use 3005# aluminium alloy as a base material, with its surface being treated with anti-oxygenized film, on which sprays 20Ám fluorine carbon polyester coating.

At present, of all materials, fluorine carbon polyester coating aluminium alloy is no doubt the lightest in weight. The turbine heads made from fluorine carbon polyester coating thus the pressure on the bearing of the ventilator is smaller and revolving sensitivity of axial bearing is naturally higher than that of galvanized ventilators.

Superior anti-corrosion, weather resistance, wearability, long service life, light weight and high sensitivity, venting efficiency is superior to similar ventilators made of other materials. This is our new product: fluorine carbon polyester coating aluminium alloy turbine ventilator.
