Key Specs
The Perkins 404 range of electric power (EP) engines is the largest, most refined member of the 400 Series. The 4 cylinder, 2.2 litre 404 offers improvements such as reduced noise, vibration and harshness (NVH). Offering the same customer benefits as the wider 400 family – such as reliability, cold-start capability, low operating costs, excellent fuel economy and compact, clever design – the 404 makes a smart choice for customers in the generator set market across unregulated and EU Stage IIIA/U.S. EPA Tier4 interim territories.
