Didde Web Press Roller 795-751

The Didde Web Press Roller 795-751 is a precision-recovered Dahlgren Water Pan Roller for Didde web offset printing presses equipped with the Dahlgren dampening system. Part number 795-751, this roller also matches Lith-O-Roll part number DG-175-63-D. As the water pan roller in the Dahlgren dampening circuit, the 795-751 sits in the fountain solution tray and picks up moisture for transfer through the dampening train — its surface condition and dimensional accuracy directly govern how consistently and how much fountain solution enters the Dahlgren system on your Didde press.

A worn or contaminated Dahlgren water pan roller undermines the entire dampening system by introducing variability into fountain solution pickup from the very first stage of the dampening circuit. The result is erratic ink-water balance, leading to scumming, toning, emulsification, and print quality inconsistencies that are difficult to correct without addressing the root cause at the pan roller. Replacing the worn 795-751 with a precision-recovered unit restores consistent, controlled moisture pickup and puts the Dahlgren dampening system back in proper balance.

Please verify the part number prior to ordering — many Didde models share rollers that may be interchangeable across configurations, and confirming the correct part number ensures you receive the right dampening roller for your specific press.
