Christianson is a leading manufacturer of ship unloaders and pneumatic conveying systems for a wide range of bulk materials including feed and cereal grains, plastics and chemicals. The company's equipment operates in agriculture, commercial bulk handling, and marine port industries world-wide.

Christianson's product line spans from small bulk seed conveyors to large ship unloaders for discharging ocean-going vessels at rates of 300 metric tons per hour.

Our roots are in agriculture and farming. In the early 1970’s we diversified into equipment distribution through our association with Dunbar Kapple/Vac-U-Vator (formerly of Batavia, Illinois). In 1979 we started manufacturing a line of pneumatic conveyors under the Handlair brand, marketing them throughout the USA and Canada. In 1989, we purchased Dunbar Kapple/Vac-U-Vator and consolidated manufacturing and international marketing operations in Blomkest, Minnesota.

Our products are marketed directly from Blomkest and through a network of independent agents and resellers. Recent international projects include installations in Australia, Vietnam, Venezuela and the Philippines.
