2 x ROOF AIR VENTILATORs – Rotary whirly/turbine type vents, white PVC plastic –for Van, Canopy, Caravan, Horse Float, Livestock,
Bus, Truck, Motorhome
This is a highly economical type of
wind-driven rotary roof ventilator – suitable for vans, trailers, trucks and
all types of enclosed compartments. It is very low profile, waterproof and
silent operating. It is made of durable PVC white plastic to not rust and to
reflect heat. The main shaft and screws are long lasting stainless steel. The
bearings are pre-packed with grease and are sealed both sides for long spinning
life and to keep dust and water out which usually shortens the life of most
rotary air vents.
This air vent has a twin-vaned air scoop
design on top of it that starts spinning when an air-stream from natural wind
or motion of the vehicle, activates it.
This spinning then creates air suction against 8 smaller air-vanes
facing the opposite direction that are located at the base of this air
ventilator (similar to how a turbocharger works). Often these air vents will spin freely just
from the forces of natural wind even when the vehicle it is parked and be
ventilating without you driving.
Remember, with this type of ventilator, the
faster you drive the faster the air will be drawn out of the vehicle. So don’t
be fooled into thinking you need an air vent with more external wind-vanes or
one with a larger opening than this 100mm diameter opening air vent – unless
the seller can tell you the exact air flow that occurs at any particular RPM.
It is
the design of the rotary vent and the speed that it is able to spin at while
driving that determines the air flow. This air vent has one of the largest
diameter external wind turbines to catch air (245mm diameter compared to 200mm
of others) to spin faster. And it has a unique ‘air-flow-through’ wind-vane
design that propels the wind-vane even faster upon exiting the rotary vent too ( see 2nd picture with arrows)
Installation is simple by first cutting a
100mm diameter hole in your roof (if requiring maximum ventillation). If you
want less ventilation, then only drill a few 10mm to 25mm holes (within the
100mm diameter area) in your roof first instead. You can always drill bigger or
more holes later for more ventilation.
To mount to your roof you will need to remove
the centre bolt locknut with a 1/2” socket so that you can separate the
stationary base plate from spinning air-vane. Then you will be able to drill 4
x 4.5mm holes to mount the circular base plate to your roof. Use pop rivets
with washers behind them if riveting into thin metal or plastic. Or use shallow
head bolts that do not stick up too far and stop the air vent spinning freely.
Note: this air vent is designed to deflect
water or rain from entering through the air vent but you should seal the base of
the air vent with silicone or sika-flex before installing on the vehicle (make sure you look at all 12 pictures
supplied here first)…
Installation instructions…
1. Pull off cap on top of
main centre bolt
2. Remove the centre bolt
locknut with a 1/2” socket
3. Separate the circular
base plate from the upper spinning air-vane
4. Cut a 100mm diameter
hole in your roof (or several smaller holes within 100mm circle)
5. Position the circular
base plate over the 100mm hole and drill the 4 mounting holes
6. Seal the base with
silicone or sika-flex and pop-rivet or bolt it on top (use large diameter
washers behind the rivets or bolts if your roof is very thin for added
strength)
7. Re-install the spinning
air-vane, locknut and cap
Overall Dimensions:
Diameter: 245mm
Height: 100mm (+ 20mm if
including the small nut housing)
Roof hole diameter: 100mm
Base plate diameter: 140mm
Benefits of this type of air vent
Very easy to Install
Draws heat out from inside of vehicle
Removes stale air, leaky gases and toxic odours from
vehicles
Cool in summer and less draught in winter than other
types
Spins silently unlike electric motor ventilators
Note: if you want to shut off the air flow of these type of air ventilator then install 2 x inner vents that you can purchase from my e-store as well. Just see my other items for sale.
