Overview

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.

404D-22TAG ELECTROPAK

2.2 litre

37-40 kVA

The 404D-22TAG ElectropaK is a powerful but quiet 2.2 litre turbocharged aftercooled 4 cylinder compact package. It's designed to meet EU Stage IIIA/U.S. EPA Tier 4 interim emissions standards.

A life-time of low cost

Reliability, superb fuel economy, ease of installation and trusted components all combine to keep your cost of ownership to a minimum. Cost-saving aftertreatment options are also available.

Powerful, quiet and refined

The 404 range of engines give 20-40 kVA generator output, along with the extra refinement and noise reduction that 4 cylinder engines provide. Its power density, durability, fuel efficiency and quiet operation set it apart from similar sized competitors' engines. The 404 range's quiet operation makes it an excellent option where noise is a concern, particularly if you're operating in urban areas.
