Pramac’s GGW Gas Fuelled generators with cutting-edge Generac engines for faultless performance and low maintenance costs. The best solution for standby applications. The GGW85G produces 85kVA / 68kW 3-phase power from a natural gas engine. Due to the turbocharger on this is machine, it can only be used as a standby generator and should not be used for long run (prime) applications.
All Pramac Natural Gas and Liquid Petroleum Gas generators are built to order and take 10-12 weeks to deliver
