Midwest’s 45 consecutive years of leadership in dust control technology and manufacturing can make your loading of dry bulks safer, faster and most importantly dust free. Designed for easy installation, Midwest’s pre-engineered modules allow plant or consulting engineers to build stand alone bulk load out stations or complete loading systems using interchangeable modules. The Midwest tooling program produces superior quality products including state of the art, precision machined, ductile and non-ferrous castings, aluminum extrusions, stampings and high-tech plastic alloy components. In-house engineering and manufacturing provide the mechanical, electrical, and instrumentation capabilities to assist engineering firms or users in their quest for fast, economical dust free loading. Through this combination of high technology and quality materials, Midwest provides the best equipment available for dust free loading. Air ecology is our business, our only business. When you select Midwest, you select the very best.


When Midwest developed the first MC22-EV bulk loading spout in the 1960’s, it was smart, compact, efficient, and effective. Its success lead to the development of a complete line of spouts, positioners and integral filter modules that pioneered an industry once plagued by uncontrollable dusty environments. Today, these fundamental spout designs are an industry standard and used across the globe. After 4 1/2 decades, Midwest continues to evolve these original designs with better construction, new technologies, and more sophisticated controls.


Midwest’s nucleus is the loading spout. When you buy from Midwest, you buy from a company that is dedicated to its industry. We build loading spouts because we love loading spouts. It is in our blood, it is what we do, and it is what we will always do.


Midwest is a second-generation 100% family owned company. Founded by Ron R. Pair in 1967 and continued by his son Walter M. Pair II today. When our name is on the product, be assured it is built with pride.


Midwest project archives are maintained as far back as the early 1970’s. Still today we supply spare parts for loading spouts that are over 30 years old. When you buy from Midwest, buy with confidence that we will continue to support your spout as long as it lasts.


Engineering support is available 24 hours a day, seven days a week, to be sure your mechanical and electrical installation goes smoothly.  Our service capabilities are worldwide with field technicians equipped for installation supervision, startup, commissioning, troubleshooting, and operator training.


Midwest has secured contracts with some of the largest companies in the business, including Allen Sherman Hoff, Bechtel, Fluor Daniel, FL Smidth, Metso Minerals, BP Amoco, Exxon Mobile, Shell Oil, Cemex, Holcim, Lafarge, Carmeuse, Alcoa, Rio Tinto, Archer Daniels Midland, Bunge, Cargill, Anheuser Busch, General Mills, Kraft Foods, Procter and Gamble, General Motors, Army Core of Engineers, Basell, BASF, Dow Chemical, Dupont, and many more.
