Donaldson engine filter receives ARB approval

Donaldson Co Inc has received Level 1 Verification from the California Environmental Protection Agency's Air Resources Board (ARB) for its Diesel Oxidation Catalyst (DOC) muffler and Spiracle crankcase ventilation (CCV) filter. The DOC muffler and Spiracle CCV filter combination reduces diesel engine emissions from tailpipes and engine crankcase vents of medium- and heavy-duty trucks and school buses.

ARB approval lets Donaldson sell the combination on a retrofit basis to help meet pollution control requirements.
