This spinning motion cuts through existing advertising clutter
and gets your product noticed while the soft round corners and high
gloss injection-moulded components promote your brand due to it's
upmarket and attractive appearance.
This spinning sign is designed to start spinning as the wind blows
and through it's movement is able to attract attention even in high
traffic areas like pavements, walkways and forecourts. This sign
is the perfect choice for any business, event or company wanting
to promote itself.
Launched in 1994 our internationally patented rotating
sign has been developed and consistently improved
to provide high quality, longevity and value. With over 50 000 units
sold into Europe, Africa, Australia, USA and Asia
our spinning sign is recognized as a global leader in outdoor advertising.

The design of the spinning sign..
This spinning sign is aerodynamically designed to start rotating at exceptionally
low wind speeds, and maintain low revolutions even at high wind speeds.
More importantly to ensure pedestrian, property
and motor vehicle safety, all corners
have large radiuses and the rotating section is of a low mass.
The Windvane is manufactured to European standards, and is an
attractive high quality, aesthetically pleasing spinning sign.
spinning section is of composite construction with injection molded ABS
trim. This provides an exceptionally strong, light product, which has
an extended lifespan and is rust free. The base is moulded in indestructible
UV inhibited roto cast plastic and is colour coded to the colour of your
choice. For extra stability the base is filled with water or sand once
on site. This design philosophy reduces the overall mass of the unit and
saves on transportation and handling. The design also allows for the base
to be separated from the spinning section during shipping, thus reducing
costs. A colour coded base adds to the overall visibility
and impact of the sign and assists in creating attention and maintaining
a presence for your company.

spinning section can easily be removed from the base if so required.

The bearings are factory lubricated and do not require any maintenance.
All replacement parts are available ex stock.
The spinning sign was designed in a wind tunnel to achieve
low start up speeds, with accompanying low maximum speeds. Wind tunnel
tested in excess of 6oKph. Click here to view our
wind tunnel test video clip.
Designed to endure environmental conditions in both Northern and Southern
hemispheres, the spinning sign can withstand temperature ranges of -25
to +40 degrees Celcius. All colour coded components and printable substrates
are UV inhibited and all steel ware is electroplated to ensure an extended
Why is the design of a spinning sign so important?
Our spinning signs have been designed with a complex aerodynamic shape
which was perfected utilizing CAD and extensive wind tunnel testing. The
spinning sign is activated by wind movement and uses the exact aerodynamic
principle that keeps an aeroplane in the air. An aeroplanes wing is an
aerofoil which is designed to produce lift when air passes over it. Air
passing over the upper surface of a foil produces two thirds of a
lift by creating a lower pressure. One third of a foils lift is produced
by the higher pressure of air on the foils under surface. Our spinning
sign uses the same principle, but instead of providing lift to keep airborne
the lift of the wind is turned into rotation through the use of a low
friction bearing assembly and shaft.

The principle of lift was discovered by Daniel Bernoulli, a Swiss scientist
of the 18th century, who studied the relationship of fluid speed and pressure.
When a fluid flows through a narrow constriction, its speed increases.
This is easily noticed by the increased speed of steam when it flows through
a narrow section. The fluid must speed up in the constricted area if the
flow is to be continuous. Bernoulli wondered how the fluid got the energy
for this extra speed. He reasoned that the energy is acquired at the expense
of a lower internal pressure. His discovery, now called Bernoullis Principle,
states: The pressure in a fluid decreases as the speed of the fluid increases.
This is true whether the fluid is a gas or a liquid.
An aerofoil provides lift by taking advantage of Bernoulies principle,
this same principle is utilised in our spinning signs.
This cross-section of our spinning sign shows how rotation is initiated
through the use of an aerofoil section. The lift provided causes
the spinning sign to start rotating.
The shape of the Warp Five Windvane was developed through extensive wind
tunnel testing to ensure the best possible start up speed and the slowest
high wind velocity speed. This ensures that the rotating sign has movement
in the lightest of wind conditions, but it also has a built in aerodynamic
“brake”. This ensures that your advertising message gets the
very best chance of being seen and read in a broad range of wind conditions.
Five spinning signs have been designed to have the most favourable aerodynamic
properties required in a rotating advertising device i.e. to start rotating
in very gentle wind conditions, but through the use of aerodynamic “braking”
not to rotate too quickly in heavy wind conditions. Furthermore as the
primary function of a spinning sign is to advertise products or services
it must be aesthetically pleasing, and be pedestrian and vehicle friendly.
In order to minimize any potential damage to pedestrians or property the
rotating section of our spinning sign has a very low mass and smooth rounded
shape with large diameter corners.
What makes the Warp Five spinning
sign the world leader in wind powered rotating signs?
- Aerodynamics: a scientific, tested
and proven approach to provide our spinning sign with the very best
start up speed and lowest maximum speed.
- Design: Soft rounded corners and
high gloss injection moulded components make for an exceptionally finished
and up market spinning sign.
- Colour choice: The base and trim
of our spinning signs can be colour coded to your exact specification,
ensuring that your corporate colours get maximum exposure for increased
- Safety: By reducing the maximum rotation
speed aerodynamically our spinning sign is less inclined to “walk”
during very high wind speeds. The rotating section of the spinning sign
has a composite construction and is therefore incredibly strong but
also very light. This reduces the potential for damage to pedestrians
and property in adverse conditions, it also enables the rotating section
to be removed if required. The corners have been designed to have large
radiuses that are pedestrian friendly in the unlikely event of a collision.

Distribution: The Warp Five rotating
sign is supplied with a base that can be filled with either water or
sand at the point of use which reduces its mass during transportation.
The spinning section is of composite construction and is also very light.
The spinning section is supplied separate to the base, which allows
for very compact and economic packaging. This reduces the overall cost
of transportation, storage and distribution of the spinning signs.
- Longevity: Launched in 1994
our spinning sign has been continually developed and improved to provide exceptional
longevity. All of the materials used in the construction of the rotating
sign are UV inhibited and rust proofed to provide years of service.
- Cost: Economically priced for both
the corporate buyer and individual sign maker.

Vinyl Application Guide to the spinning sign:
Blank Windvane's are supplied disassembled with colour coded side
strips and top and bottom capping strips.
Apply your vinyl to the blank windvane. It is a good idea to use
a larger piece of vinyl than the size of the windvane which will
allow you to position the vinyl easier and then trim off the excess.
Attach the side strips and capping strips by placing them in place
and fixing with the screws provided.
You have sucessfully applied artwork to your new Windvane!
