Overview
The Sumec Firman RD4910 is a portable 3.1kVA petrol generator designed to keep essentials running during grid failures. It delivers single-phase AC power suitable for appliances like fridges, lights, TVs, fans, small pumps and shop equipment.
It uses a 4-stroke, single-cylinder OHV air-cooled engine with combined recoil and electric starting for flexible operation. The generator includes AVR voltage regulation and an IP23 protection rating for outdoor use with basic weather protection.
With a 15 L fuel tank and efficient engine, it can run many hours at partial load — making it practical for homes and small businesses that need extended backup without constant refuelling.
Key features
- Rated power 3.1kVA for single-phase household and small commercial use
- 15 L fuel tank for long run times between refuels
- Recoil and electric start for reliable starting options
- AVR voltage regulation to protect appliances
- IP23 protection for outdoor operation
