Double Protection To The Ball
Bearing
BigBird ventilators are designed
with nylon dust cap (resistant to 170°) and bearing housing to protect
the ball bearings against dust, which if in excess, will deter the movement
of ball bearings. |
|
All Aluminium, Anticorrosive
Construction
(Grade 5005 H34)
Be it rain or shine, BigBird aluminium
construction will remain rust-free and it requires no maintenance. |

Silent Operation
Using free wind energy, Wesflo operates
quietly, making you unaware of its presence. Designed in Australia for
Australian conditions. |

Turns With the Slightest Breeze
All it takes to turn your BigBird
is a slight breeze. Yet, it can withstand wind velocity of 193km/h. Six
shaft arms for added strength. |

Steel Ball Bearings Work Indefinitely
BigBird rotates on two precision
steel ball bearings which are individually sealed and
lubricated to work for a longer
life. |
|
Eave Vent
The eave vent will help to remove
hot and trapped air from ceiling to roof, thus facilitate the operation
of BigBird. |
