Why does Ausroad™ use the venturi delivery system and not a rotary distribution system?
The venturi delivery system that Ausroad™ uses is the most efficient way to distribute aggregate into an air stream. Now powered by PTO it has no moving parts and requires no regular maintenance or additional power source. The Venturi increases the air velocity by 60% after it leaves the blower making the venturi system the most productive available. By reducing the speed of the blower the operator has exact control over how much aggregate is delivered via the venturi and delivery hose. Unlike a rotary distribution system it can handle a variety of aggregates from sand to 12mm, wet and dry. It is lighter, cheaper to maintain and more effective than any other system. With no moving parts the patented venturi system is the safest and most efficient system available.
