Petrol-powered back-pack ULV cold fog aerosol generator
In the 1970s, the fontan® ULV-R was the first portable cold fog machine that was exclusively designed for use in the ULV spraying method. The device has been continuously developed, and our actual fontan® Portastar S device is based on this concept. Our fontan® Portastar S is probably the most popular and best-selling ULV back-pack device worldwide.
The device is powered by a robust 2-stroke motor and started by a recoil starter.
