The Omni 120-E model is the most-economical 250 V.A. single lamp blueprint machine available, yet contains many features of the Omnitrac models. These features include user friendly solid state dual range speed control that can be switched from normal high speed to a low speed range for printing precision specialty intermediates, a forward/reverse switch, and a simple on/off operation without waiting for warm-up. The Omni 120-E does not include the TRAC System. However, the exclusive DiAZiT Ammonia Arrestor System is optional if required. The Omni 120-E can be used as a tabletop model incorporating a Feedboard or it can also be mounted on the Omni 120-E Stand as pictured above with a Feedboard or Roll Box.
