In 1972, N. R. Murphy Ltd. entered a partnership with Rodgers Machinery to form Murphy-Rodgers Inc. to manufacture dust collectors in Los Angeles, California for the United States market. Both companies grew over the years and developed dust collection equipment for all types of industries.

With the passing of Otto Seeman, President of Murphy-Rodgers Inc. in October of 2010 a decision was made to close Murphy-Rodgers Inc. and move all the sales and production functions to N.R.Murphy Ltd. in Cambridge, Ontario.
