Ampelair Turbo Superflow Ceiling Cavity Vents

 Ampelair turbo vents exhaust the very hot air that becomes trapped in the space between the ceiling and the roof. This prevents heat radiation into rooms.

A well ventilated home is protected from problems associated with moisture condensation and temperatures that can soar to a b
listering 60°C. In hot humiud localities, mould, mildew, dry rot and damp insulation (which becomes inefficient), is frequently found where proper ventilation is not provided.

Normal insulation is not enough to prevent heat radiation into your home. With effective roof space ventilation less heat is radiated into your rooms and air conditioners and fans can cope more easily. Power costs are also reduced.

Removes Damp Air -
Saves On Heating..

Moisture laden air from inside the home, and outside air, can condense and cause dampness. Good ventilation prevents damage to ceilings and roof timbers, formation of mildew etc. Shaded areas of your home particularly benefit.

Ceiling insulation loses its effectiveness when it becomes wet, and as a result, increases the need for heating to compensate for heat loss. Damp conditions can aslo cause ceilings to become mildewed. Proper ventilation of the roof space overcomes these problems and helps lower heating costs. Bathroom and kitchen vetilation is also improved.

We recommend installation of 2 under eave vents per AA300 ventilator to ensure correct operation.

One Ampelair AA300 turbo ventilator effectively ventilates the roof space of an average size home. For larger homes a second ventilator is required.

The Ampelair Superflow ventilator is the first major advance in wind driven turbo ventilator design since their introduction over 50 years ago.  Tests made against standard design ventilators of the same throat size (300 mm), show an increase in performance of around 40% under commonly found operating conditions.



Conventional rotary roof vents work by continually creating a vacuum in the head of the vent.  This causes air to be extracted from the space below.  Using atmospheric pressure in this manner is similar in principle to that of a family motor car engine.   The Superflow fan acts like a high performance car turbo charger forcing extra air through the vent head  to increase the exhaust capacity.

COLORBOND® steel offers a modern range of 20 designer colours for Roofing, Walling, Guttering, Downpipes and Fascia as part of the standard range.

If placed in the underside of your eave will allow more air flow and ventilation to the ceiling cavity (recommended).
Normally rotary ventilators are utilised to extract heated air from the ceiling cavity, however they can also be used to replace electric powered ceiling fans to allow natural and direct ventilation of laundries, toilets, kitchens and bathrooms to the outside air rather than a ceiling space (Kit includes 1x ceiling register with damper, 1x transition connection from register to duct, 1x3metre flexible duct, note it does not include superflow rotary ventilator).

Required in all bushfire prone areas, clips under the superflow rotary ventilator to prevent ember access to the ceiling cavity.
Forms part of the "room ventilation kit" and can be purchased seperatly.
