Rental High-Performance Tier 4F Generators For Ultra-Low Emissions
Minimize emissions while maximizing performance
Our Tier 4 Final generators meet the highest emission standards, helping you reach your sustainability commitments
Designed to cut down on harmful pollutants, our Tier 4 Final generators comply with the most stringent requirements of the United States Environmental Protection Agency (EPA) for diesel engines.
With similar operation to the cleanest car engines, these cleaner power generators lower regulated emissions like NOx, particulate matter (PM), and CO. And CO2 emissions are reduced by minimizing fuel consumption using environmentally-friendly biofuels.
Compared to the basic engines in older generators, a Tier 4F generator can deliver a 98% reduction in particulate volume and produce 96% less NOx gas. All are available individually or as part of our Energy Transition Solutions to lower your emissions.
So you can guarantee compliance with Tier 4 Final emissions standards - without compromising on performance.

Aggreko is setting the standard for environmentally-friendly, low-emissions generators in the rental industry
At Aggreko, we’re proud to offer the largest fleet of Tier 4 Final generators in North America. With models ranging from 25kW to 1,200kW in capacity, we can provide a cleaner power generator for any application.
As you’d expect from Aggreko, you get more than compliant power to meet Tier 4F emissions standards. Our entire fleet is robust, fuel efficient, and low on noise. All supported by remote monitoring - so you can understand emissions across your project and optimize, control, and manage performance with ease.
How to reduce emissions with Aggreko low-emission generators
Installed and monitored by our experts, our Tier 4 Final generators deliver low-emission power generation through improved technology.
Across the range, you’ll find features including:
- Diesel particulate filter to reduce particulate matter
- Selective catalytic reduction system to reduce NOx emissions
- Diesel oxidation catalyst to reduce CO emissions through oxidization
- Low noise with variable-speed fans to reduce sound at lower loads - ideal for urban areas
- Arc flash detection and physical safety barriers to protect operators
- Internal Diesel Exhaust Fluid (DEF)/AdBlue tank matches to internal fuel capacity - so the DEF only needs to be filled when the tank does
- External DEF/AdBlue tank options to extend on-site refill intervals, supply multiple generators, and reduce site installation footprint
The whole fleet across an entire project must be monitored. Our remote monitoring lets you optimize, control and manage your on-hire fleet with ease.

Frequently asked questions about Aggreko cleaner power generators
Tier 4 Final is the final phase regulating emissions from new and in-use non-road compression-ignition diesel engines. It exists to reduce emitted harmful substances like NOx, building on previous emissions standards.
In place across 2011 and 2012, Tier 4I was the first step toward the new standards set in Tier 4F. Tier 4I (or Tier 4 Interim) focused on reducing CO and particulate matter, while Tier 4 Final embeds stronger requirements around NOx.
Driving down emissions on a global basis takes a connected, cohesive approach. Stage 5 (or Stage V) is a set of European emission standards for off-road engines – a counterpart to the US Tier 4 Final emissions standards.
In the US, EPA emissions regulations govern the use of temporary power generators. Some of the key regulations include:
- A five-stage schedule for emissions reduction on all engines, driving the development of more complex low-emission engines
- Nitrous oxide (NOx) reduction – these emissions remain in the air for longer than CO2, causing acid rain
- Particulate matter (PM) reduction – these small carbon particles are created by the incomplete combustion of fossil fuels and cause poor air quality and health
