ROTARY VENTILATOR :
DUO- FAN
Unique Duo-Fan construction where the supports for the lower bearing also act as fan blades
which enhance the flow of ir through the intake of the ventilator improving overall performance.

BALL BEARING
Micro steel conceal bearing 608 - 2RS is design to spin at high speed and
the ball bearing will float creating friction free.

CORROSION RESISTANT
The ozvent ventilator is manufactured from high grade aluminium (Grade AA1100)
including the rivets and shaft, therefore highly resistant to atmospheric corrosion.
Where steel parts are necessary they are either zinc, nickel or cadium plated
to ensure they match the corrosion resistance of the aluminium.

STRENGTH
The Ozvent ventilator is double riveted to provide extra strength ans is designed with
internal bracing to withstand winds in excess of 205 km/hr (see over).
The corrugated die pressed vane shape provides more strength, stability and uniformity.

WEATHER RESISTANT
The design of the aerofoil vanes ensures rainwater drains away from the ventilator.
The vane shape combined with the rotation of the ventilator creates
continuous outward movement of air preventing any rainwater
from entering the Ozvent ventilator.

FIT ANY ROOF
Vari - pitch base fits any roof from 0 - 45 degrees and can be easily adjusted.
(300mm ozvent only)

CAPACITY
A huge capacity increase compared to all previous ventilators.
This gives the industrial architect a greater flexibility in designing industrial buildings.

WEIGHT
The home BS ventilators are extremely lightweight
(the BS400 is only 4.8kg, BS 460 is only 5.5kg and the BS 600 only 9kg)
to provide strong ventilators that will operate at very light wind speeds.
At these weights the BS 460, BS 600 are less then 50% of the weight of the equivalent size steel ventilator.
This not only means better performance in light winds but also means that the roof structure
may not require reinforcement to mount the Horne BS ventilators.

VANE DESIGN
The vanes are profiled and rolled to provide a strong blade with good aerodynamic performance.

ALUMINUM CONSTRUCTION
All aluminium construction including the waterproof rivets provide a lightweight,
easily rotated ventilator suitable for most industrial environments.

STAINLESS STEEL SHAFT
The Shaft is strong but lightweight 304 Stainless Steel to provide
a corrosion free backbone for the ventilator.
