Overview

The Sumec Firman RD3910 is a 3kVA petrol portable generator built for steady, everyday backup power. It uses a 4-stroke, single-cylinder OHV air-cooled engine paired with a brush-type alternator and AVR for voltage regulation.

With a 15 L fuel tank and long run times at partial loads, this unit is aimed at homes, small shops and light office use where grid interruptions are frequent. Recoil start and robust protection make it practical for site or household standby.
