Briggs and Stratton 40422 Details and Specifications

Briggs & Stratton 19kW Standby Air Cooled 3 Phase 240V Natrual Gas/Propane Generator Model 40422

Briggs & Stratton has developed a 3-phase solution without the 3-phase price tag; don't pay for power you don't need.  If you have smaller commercial 3-phase power needs you are no longer forced to invest in a larger, liquid cooled generator saving you money and space with our innovative 3-phase air cooled standby generators.

The compact footprint, front exhaust and lower weight compared to liquid cooled options in the market will provide you flexible placement options and concrete pad NOT required (code dependant).  We have also invested in this design to make sure service can be conducted easily with our hinged top and removable side panels while still maintaining a sleek aesthetic.  Installation cost could also be minimized by eliminating the need to place the generator with a crane that larger, commercial units might require. 

Backed by one of the best warranties in the industry that covers both parts and labor for 4 years this generator will give you the assurance that you will keep the lights on when you need it most.

More Features and Benefits:

Reliable Engine Power - Our standby generators are powered by commercial-grade Vanguard engines that are design-engineered to dependably take on the most demanding jobs.

Simple Maintenance - More service access to the engine and alternator plus a user-friendly control panel make repairs easier and less costly for home and business owners.

4-Year Limited Parts and Labor Warranty - At Briggs & Stratton, we stand behind our warranty and make it easy for our customers to work with us.

Durable Enclosure - Rust-resistant, galvanneal steel enclosures are made from the same materials used in the autmotive industry and feature an advanced powder coat paint process, resulting in years of protection against chips and abrasions.

Quick Response - Automatically powers your home or business in seconds after sensing a power outage.
