About Ward Clean Air Products

Our mission is to provide our customers with customized and cost-effective emission control systems for their diesel retrofit mandates.

Globally, we offer a full range of diesel retrofit products for OEM, Aftermarket, and Retrofit markets, to reduce diesel emissions from on-road, off-road, and stationary diesel, gasoline, and alternative fuel engines, including propane and natural gas.

Manufactured in ISO 9001 facilities, Ward Clean Air Products offers products from Engine Control Systems (ECS), Huss, DCL-International, Webasto, Racor-Parker, Firwin, and more. These products have been designed for ease of installation, peak performance, and long life, with a proven service history.

These diesel retrofit solutions have been proven in the most severe conditions, including underground and open-pit mining, tunneling, industrial/stationary power generation applications, urban transit, school bus, and on- or off-road fleets. Our products help ensure air quality, productivity, and employees' health and safety on the job.

To ensure your equipment's uptime, we use only premium grades of stainless steel and welding materials to prevent corrosion or premature failure. And if you require any field support, we will be there to support your operation and keep you on the go.

Our products have confirmed performance through the use of third party testing facilities, verifying with regulatory agencies and, most importantly, with our customers.

We offer a high level of service and expertise, to small companies with a few applications, as well as to large fleet operators or OEM.
