Dayton Professional-

Duty Electric Generators

Description

Dayton professional-duty generators are rugged and compact to provide dependable,

trouble-free service. The alternators are brushless with revolving fields. Honda gasoline

engines provide long life under heavy use. Overhead valves (OHV) provide high perfor-

mance with lower fuel consumption. These engines are governed to maintain engine

speed of 3600 RPM under load. 3600 RPM engine speed provides 120/240V, 60 Hz

power. Additional features include circuit breaker protection, spark-arresting muffler

(except Model 3WY47), large fuel tank, and oil alert system. Models 3WY45, 3WY46,

and 3WY47 include electric starter.
