D690 Round DamperLOW-LEAKAGE, SINGLE-BLADE
APPLICATIONThe D690 Round Damper is used in conventional air handling systems to control airflow in a round duct. The damper is specifically designed to mount to the Honeywell actuators.
FEATURES• Neoprene and silicone seal for tight closing and low
leakage.
• Oilite bearings for long life.
• 90-degree damper travel for a variety of applications.
• Designed to mount to a variety of Honeywell actuators for an economical package.
