Donaldson Co. Inc. said it has implemented targeted price increases for its Industrial Air Filtration product lines, effective April 4. It also has given notice of targeted price increases for certain Engine OE filtration and OE exhaust system product lines that will become effective at various times in the second half of 2011 based on the applicable notice period or commodity indexing term.

The specific price increases will vary and are dependent on the specific types and quantities of raw material content in each product line. These price increases are a direct result of the significant increase in costs of steel and all petro-chemical based purchased materials.

"We are working with our key suppliers as well as utilizing our internal continuous improvement initiatives to mitigate as much as possible the impact of all purchased material cost increases. Unfortunately, the magnitude of some of these cost increases is also requiring selective price increases. We remain committed to providing the best value, service, quality and technology to our Customers," said Bill Cook, chairman, president and CEO.
