The Purimuffler exhaust system is the response by Ward Clean Air Products to the requirements set by the EPA for the reduction of harmful emissions of diesel powered vehicles.

Ever since the Clean Air Act was first passed back in 1963, the manufacturing world has had to address the problem of the quantity of pollutants their trucking fleets have produced.  In 1990, this federal act was amended to better address the problems of acid rain, ozone depletion, and toxic air pollution. From this point forward, many businesses have specialized in helping these fleets reduce their emissions.

Ward’s Purimuffler components that are attached to a diesel exhaust system are made from the highest quality stainless steel and welded products. This is to help ensure their long life and continuous performances of reducing emissions to the systems they are attached to. They were designed to be retrofitted into existing systems, to help reduce the cost of fleet owners complying with the ever stricter federal regulations on the amount of permissible emissions that are allowed to leave the tail pipe of a diesel powered vehicle.

The Purimuffler and Purifilters that are produced by Ward have been tested by third party testing facilities, to ensure they meet or exceed the federal regulations. These positive results on the reduction of pollutants that are contributed to the Ward Clean Air products have been verified by the federal regulatory agencies.

The list of these pollution reducing products are many but include the Purimuffler, the Purifilters with passive regenerating DPF, Diesel Oxidation Catalyst and the Combofilter with active regenerating DPF. The Purimuffler and Purifilter have verified results of 20% to 40% toxic emission reduction that is verified.

An added benefit of using the Purimuffler exhaust system beyond the reduction of pollutants is the increased fuel efficiency that many of the users are reporting. By complying with this federal regulation, it is a win-win situation for both the owner and the general public.

In these days of spiraling fuel costs, it is good to see that at least one response to this new government mandate also helps to increase fuel efficiency.
