Paul Lechler founded Lechler GmbH in 1879 as a specialty industrial supplier in Stuttgart, Germany. By the 1890's Lechler had acquired specialized nozzle technology and became a manufacturer.

In the 1970's, Lechler formed a relationship with Spraco, a long established nozzle manufacturer in the United States. In 1987, Spraco became Lechler, Inc., which serves North America and is the second largest sales and manufacturing company in the Lechler Group. Today, Lechler is still owned by the Lechler family and has manufacturing facilities and sales offices worldwide.

Lechler, Inc. is part of the Lechler Group of international companies. As a whole, the Lechler Group is one of the largest manufacturers of spray nozzles, systems, and accessories in the world. Our products are used for applications in manufacturing, environmental engineering, and agriculture. Specific markets for which we routinely engineer systems include steel, pulp and paper processing, environmental control at energy power plants and cement manufacturers, and wastewater treatment facilities. In addition, Lechler products are widely used in chemical plants, at pharmaceutical facilities, for electronic circuit board manufacturing, during beverage processing, by food makers and processors, and in general by any manufacturing facility that has a need to spray fluid or air.
