Dukane Model 4000 (28A4000)
Overhead Transparency Projector
Includes ViewFrame Spectra C LCD Projection Panel

The Dukane Model 4000 is a classic industrial overhead projector designed for educational and professional presentations. This specific unit is paired with a ViewFrame Spectra C LCD projection panel, a notable piece of technology from the early digital transition era. By placing the LCD panel on the projector stage, users could project digital computer signals before integrated data projectors became standard. This combination represents a significant step in audio-visual history, bridging the gap between analog transparencies and digital media.

• Large fresnel lens stage suitable for standard transparency sheets and the included LCD panel
• Integrated ViewFrame Spectra C LCD Projection Panel for digital source connectivity
• Portable fold-down design with a built-in carrying handle for ease of transport
• Dual-lamp changer mechanism and high-output cooling fan for extended use

Condition: The projector housing shows moderate surface wear, scuffs, and dust consistent with its age and professional use. The fresnel lens and mirror appear intact but require cleaning. The ViewFrame LCD panel shows light surface scratches on the protective glass. No power cord or connection cables are present. Functionality has not been confirmed as the unit was not tested. Sold as-is for parts, repair, or collector use.
