Multi Systems

An alternative to whole home ducted systems, the new Fujitsu General 3 and 4 Rooms Multi Systems are designed for homes where traditional ducted systems are impractical. It can connect up to four indoor units to a single outdoor unit. The system uses R32 refrigerant technology, which has a 67 per cent lower global warming potential (GWP) factor than commonly used R410A, without compromising performance.[1]
