Circular Shut-off Dampers | Type AKK

Shut-off dampers Type AKK

Circular shut-off dampers in PPs plastic for air conditioning systems, available in 6 nominal sizes. Suitable for shutting off or restricting extract air flows containing aggressive substances since all components coming into contact with the airflow are made of plastic (no interior metal parts). 

Application

• Suitable for duct pressures up to 1500 Pa.
• Plastic circular shut-off dampers Type AKK for shutting off or restricting the airflow in ventilation ducts of air conditioning systems
• Suitable for contaminated air
• Ready-to-install unit consists of the casing with a damper blade.
• Spigot, suitable for ducts according to DIN 8077.

Key Features

• Maintenance-free damper blade mechanism
• Closed blade air leakage to EN 1751, class 3
• Casing air leakage to EN 1751, class B

Optional equipment and accessories

• Electric actuator
• Spring return actuator
• Pneumatic actuator
• Auxiliary switch with adjustable switching points for capturing the end positions

Special features

• Damper blade can be actuated manually, electrically or pneumatically
• Low-leakage shut-off
• Safety function provided by optional spring return actuator
• Nominal sizes:125, 160, 200, 250, 315, 400

Variants
