NANOTEK BLF230B — 5 Nm Fire Damper Actuator

Description

The NANOTEK BLF230B (5 Nm) is a spring-return electric actuator designed to control the position of fire dampers, smoke exhaust dampers and ventilation dampers in fire protection and smoke extraction systems.

The actuator is primarily intended for fire-retarding and normally open fire dampers. Depending on the system design, it can also be used for smoke exhaust dampers, smoke control dampers and normally closed fire dampers.

The actuator provides a minimum torque of 5 Nm, operates on a 230 V AC power supply and features an IP54 enclosure protection rating. With a service life of up to 60,000 cycles, it is suitable for professional ventilation and fire safety automation systems.
