Self-actuating Backflow Protector - Insert
Designed to prevent the spread of smoke between different fire cells.
Product Information
The EKO-BSV self-actuating backflow protector is designed for use in ventilation systems in housing, hotels, and service apartments to prevent the spread of smoke via the intake air system in ventilation systems. The protection is specially adapted for FT and FTX systems with fans in operation, and the principle is to prevent backflow in the supply air ducts in the event of a fire. EKO-BSV closes quickly in the event of a fire that generates an overpressure in the fire cell. It is fully self-actuating and does not need to be connected to a monitoring system. This provides reliable and cost-effective fire protection.
