Blue M Friction Aire® ovens provide a controlled heat source without heating elements, which eliminates atmospheric explosions and ignitions when working with hazardous Class 1, Group D materials. Class 1 atmospheres contain flammable vapors, and Group D materials include many solvents commonly used in finishing applications, such as lacquers and paints. 

Underwriter's Laboratories (UL) lists three models of the Friction-Aire family. 

Three models have been listed by Underwriter’s Laboratories for operation in Class 1, Group D hazardous locations. They are ideally suited for the testing and processing of hazardous materials, paints, solvents and lacquers. There are no heating elements in the chamber and no inherent hot spots to create potential danger. Tests show that load temperature follows closely behind chamber temperature. If the application calls for the processing of hazardous materials over extended periods, the load temperature and chamber temperature will be practically equal all of the time. When chamber and load reach complete equilibrium they will remain so indefinitely until the temperature is deliberately changed. Even if spillage of flammables inside the chamber occurs, danger is minimized because any surface the liquid encounters is only as hot as the interior environment. 

This industrial safety oven is UL listed for Class I Group D operation and is the first and only industrial safety oven to have this listing.
