Poles 2, 4, 6 & 8
Smoke Extraction Motors at 250° / 300° / 400° for 2 hours
Key Features -----
Protects exposure to smoke during fire: Support firefighting by creating a smoke-free zone
The Smoke-Extraction Motors operate as “Dual-Function Motors” : Single motor can operate at both S1 & S2 Duty Cycle
Endures upto 400 °C for 2 Hours : Operation range - 250 °C / 2 Hour to 400 °C / 2 Hour
Comes with Separate Terminal Box assembly
The Smoke-Extraction Motors operate as so-called “Dual-Function Motors”: Normal operation (no instance of fire): Incoming/Outgoing air flow Fault operation (in case of fire):- - - - - Removal of smoke from escape & access routes Supporting firefighting by creating a smoke-free zone Protecting devices & equipment Reducing the heat stress of components during a fire Reducing secondary damage due to thermal bi-products & hot gases The declared nameplate performance unchanged at elevated temperatures. This helps to design the smoke extraction systems in compact size. Radial-Flow & Axial-Flow fan drive are possible. Self-ventilated motors with a metal fan impeller can be used as radial-flow fan drives. Forced Air Cooled Motors can be used as axial-flow fan drives taking into account the required volumetric flow of motor cooling. In this case the driven fan performs the ventilation.
