Lawson Blazer: Modular and Versatile Screen Printing and DTG Conveyor Dryer

The Lawson Blazer screen printing and DTG conveyor dryer is designed for maximum flexibility and versatility. Its fully modular design can be easily customized and expanded to meet changing needs, making it an ideal investment for screen printing operations.

The Blazer is engineered for curing plastisol and water-based inks. The base model is only 8 feet long and includes one 3-foot heat chamber or curing module of your choice. Additional heat chambers or curing modules can be added at any time, even years later.

With true edge-to-edge heating elements, the Blazer ensures consistent heat without increasing utility costs, unlike dryers with angled heating elements. The Arrow Belt™ conveyor system automatically tracks the dryer belt for reliable operation.

Select a standard belt width and length, or customize to fit your specific needs. The in-feed or out-feed of the Blazer can be extended at any time, offering total modularity.
