Winco - Model PSS21F4/3 - Gaseous Standby Generator- Brochure

Our PSS21F4 standby generator is a perfect for many different power needs. This unit can run on LP or natural gas. This unit is unique in that it has a very over-sized engine (same engine as our PSS30) and an over-sized  generator end. Therefore, when you pull full load on this generator, it will hardly break a sweat. It is not unreasonable to expect 20-30+ year s  of service from a well-maintained unit like this.
