Marine Multi-Blade Fire Damper
Marine Multi-Blade Fire Damper is a regulator that consists of multiple blades that can be adjusted for flow by adjusting the blade pitch. Marine multi-blade fire damper is suitable for fire protection isolation of large air conditioning and ventilation systems, gas and liquid fluid transportation pipelines. The blade structure is the biggest difference between single-blade fire damper and multi-blade fire damper, which is also the most critical part of the fire damper.
Overview
Marine Multi-Blade Fire Damper have the advantage of a large number of blades and high precision, so they are often used in applications with higher air flow requirements, such as CLEAN ROOM and other environments. Marine multi-blade fire dampers have multiple sets of blades that can be combined as needed for more sophisticated air flow distribution control.
Performance Differences:
Multi-blade fire damper has larger caliber than single-leaf fire damper.
Due to the different number of blades, multi-blade fire damper is better than single-blade fire damper in sealing performance.
Single-blade fire dampers are mainly triggered manually or electrically, while multi-blade fire dampers can be automatically activated by signals.
