Business Combinations [Abstract]
Acquisitions	Acquisitions On October 18, 2018, the Company acquired 88% of the shares of BOFA International LTD (BOFA), headquartered in the United Kingdom, for cash consideration of $98.2 million less cash acquired of $2.2 million. BOFA designs, develops and manufactures fume extraction systems across a wide range of industrial air filtration applications. The acquisition will allow Donaldson to accelerate its global growth in the fume collection business and add additional filtration technology to the Company's existing product lines. The fair values assigned to the acquired assets and liabilities assumed of BOFA were approximately $12.2 million of net tangible assets, $45.7 million of identifiable intangible assets, $73.6 million of goodwill, $8.1 million of deferred tax liabilities and $14.3 million of assumed debt. The assumed debt was repaid in October 2018. The identifiable intangible assets were related to customer relationships, patents, trademarks and technology and have estimated useful lives ranging from 5 to 15 years. The acquired intangible assets including goodwill are not deductible for tax purposes. The purchase price allocation is preliminary pending the outcome of the final valuation of the net assets acquired. The Company is reporting BOFA’s results of operations within the Industrial Products segment. Transaction costs were expensed as incurred and were not significant for the three and nine months ended April 30, 2019. The acquisition also provides call and put options that, if exercised by either the Company or the minority interest holders after three years, would obligate the Company to purchase the remaining 12% of the shares of BOFA at a price indexed to the performance of the acquired entity. Due to the redemption features, the minority interest holders’ value is classified as a redeemable non-controlling interest in the Company’s Condensed Consolidated Balance Sheets. The redeemable non-controlling interest was recorded at fair value at the date of acquisition and there were no significant changes to the carrying value during the three months ended April 30, 2019. Pro forma financial information for this acquisition has not been presented because it is not material to the Company's consolidated results of operations.
