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.
