President and Owner, Wally Haag has worked in the Industrial Vacuum Field since 1974. He first started out in the manufacturing area, working his way into Field Service Management, and New Product Development. In 1980, Mr. Haag purchased half ownership of M&W Shops, Inc. (a custom metal fabrication shop) where he continued to use his experience to manufacture New Weldments and Special Vacuum Equipment. In 1990, Mr. Haag took full ownership of M&W Shops. At that time, the decision was made to use his engineering experience of Heavy Vacuum Equipment and Metal Fabricating to design a new maintenance friendly product line of Vacuum Cleaners, Loaders and Conveyors which is now Multi-Vac. Since that time, Multi-Vac has become a well known and respected name in steel mills, foundries, cement and brick plants as well as in the mining, plastic, rubber and chemical industries. Successful installations are in use from the East Coast to the West Coast, South America, Canada and Mexico.
