Piano Humidity Control | Piano Keys

Broken, sluggish, and sticky piano keys are the result of changes in relative humidity. Piano key tops, piano key bed, metal, felt, cloth and piano key wood all swell and contract at different rates. Keys, keytops, and flanges can break. Action parts, hammer butt plates, flanges, hammer heads can become loose. It is common to see the flange pin and butt plate come loose allowing side to side hammer play that can contact the adjacent hammers. Additionally, felt can deteriorate, damper and wippen flange screws can come loose causing clicking sounds when a key is struck. These problems go away with the installation of a Dampp-Chaser Piano Life Saver System.

Control piano humidity to prevent damage to piano keys, soundboard, tuning pins, pinblock, loose action screws, delaminate pinblock and bridge.

Testimonials

  • Petrof company recommends the Dampp-Chaser System with Petrof Pianos to enhance tuning and regulation stability, especially those pianos placed in areas that are subject to great air humidity changes or to extreme high or extreme low humidity levels. Without such a system, it is very difficult to control the air humidity in the immediate vicinity of the piano. -- Zuzana Ceralov√° Petrofav√°
