The RB70m is a portable, low-cost silver roll film duplicator designed for high-quality duplication of both positive and negative 16mm and 35mm roll films. Its key feature is the improved film drive and transport mechanism, which ensures that the film emulsion never comes into contact with the drive rollers, reducing the risk of damage. The duplicator operates at a consistent speed of 10 meters per minute and produces silver duplicates that are processed through a microfilm processor with conventional chemistry. The unit is compact, user-friendly, and ideal for low to medium-volume operations. With a removable copy film cassette and new exposure and clutch mechanisms, the RB70m offers excellent resolution and reliability.
