KPU-2N(1) Universal Fire Protection Ventilation Damper

Description

The KPU-2N(1) is a universal fire protection damper designed to automatically close ventilation ducts or openings in building structures to prevent the spread of fire, smoke and gases. It is suitable for general ventilation, air conditioning, supply and exhaust smoke control systems, as well as systems designed to remove gas and smoke after fire suppression using gas, aerosol or powder extinguishing agents.

The damper provides an EI 120 fire resistance rating and can be equipped with a solenoid actuator, spring-return electric actuator or reversible electric actuator depending on the application.
