Re:	Colfax Corporation
	Registration Statement on Form S-3

Ladies and Gentlemen:

We have acted as counsel to Colfax Corporation, a Delaware corporation (the “Company”), in connection with (i) the preparation and filing with the Securities and Exchange Commission (the “Commission”) of a Registration Statement on Form S-3 (the “Registration Statement”), under the Securities Act of 1933, as amended (the “Securities Act”); (ii) the prospectus included therein; (iii) the prospectus supplement, dated February 18, 2021, filed with the Commission on February 18, 2021 pursuant to Rule 424(b) of the Securities Act (the “Prospectus Supplement”); and (iv) the offer and resale from time to time by the selling stockholders identified in the Prospectus Supplement (the “Selling Stockholders”) of up to 3,297,209 shares of the Company’s common stock, par value $0.001 per share (collectively, the “Shares”). The Company previously issued and sold the Shares to the Selling Stockholders pursuant to securities purchase agreements entered into with each of the Selling Stockholders on January 24, 2012, in reliance on an exemption from the registration requirements of the Securities Act, and registered the Shares pursuant to the terms of registration rights agreements the Company entered into with each of the Selling Stockholders on January 24, 2012.

We have examined the originals, or photostatic or certified copies, of the Registration Statement, the Prospectus Supplement, such records of the Company and certificates of officers of the Company and of public officials and such other documents as we have deemed necessary or advisable to enable us to render the opinions set forth below. In our examination, we have assumed without independent investigation the genuineness of all signatures, the legal capacity and competency of all natural persons, the authenticity of all documents submitted to us as originals and the conformity to original documents of all documents submitted to us as copies.

Based upon the foregoing examination and in reliance thereon, and subject to the assumptions stated and in reliance on statements of fact contained in the documents that we have examined, we are of the opinion that the Shares have been validly issued and are fully paid and non-assessable.
