Damper Maintenance
Dampers do not typically require maintenance as long as they are kept dry and clean. If cleaning is necessary, use mild
detergents or solvents. If lubrication is desired for components such as axle bearings, jackshaft bearings and jamb
seals, do not use oil-based lubricants or any other lubricants that attract contaminants such as dust.
Dampers and their actuator(s) must be maintained, cycled, and tested a minimum in accordance with:
• The latest editions of NFPA 80, 90A, 92A, 92B, 101, 105, UL864, AMCA 503-03 and local codes.
• Actuator manufacturer recommendations.
