The Cummins RS40 Keeps Your Business Running No Matter What
When the power goes out, your business can't afford to stop. The Cummins RS40 commercial generator delivers reliable 40kW backup power that kicks in automatically, so you never miss a beat. Whether you're running a small manufacturing facility, medical office, or retail operation, this generator has the muscle to keep your essential systems online.
Built to Handle Anything Mother Nature Throws at It
This isn't your typical backup generator. The RS40 is engineered for the real world, including cold weather starts as low as -40°F when equipped with necessary accessories. Its rugged aluminum enclosure with powder-coated finish resists corrosion and weathering year after year and sustains hurricane force 180 mph wind loads. Plus, it's one of the quietest generators in its class, so you won't disturb your neighbors or employees when it's running.
Smart Exercise Mode Saves You Money
Nobody wants their generator running more than necessary. The RS40's flexible exercise mode lets you set when and how often it tests itself – as little as 2 minutes every 6 months. This smart feature cuts down on fuel costs, reduces emissions, and keeps noise to a minimum while ensuring your generator stays ready for action.
Service Made Simple
When you need maintenance, the RS40 makes it easy. Removable panels and strategically placed service doors give technicians quick access to all the important components. The PowerCommand electronic control system continuously monitors performance and alerts you to any issues before they become problems, helping prevent costly downtime.
