TROX smoke extraction damper EK-JS

• For use in dissipation environments of elevated temperatures up to 600 °C on tested smoke extraction pipes and sheet steel pipes
• Meets pressure level 3 at any airflow direction and automatic triggering (AA)
• Nominal sizes 100 × 100 – 1250 × 2560 mm
• Volume flow of 360 m³/h or 100 l/s – 115110 m³/h or 31975 l/s at 10 m/s
• Version in sheet steel (also powder-coated according to RAL-CLASSIC card) or stainless steel sheet in A4 quality
• According to EN 1751: Leakage air flow with closed flap at least class 2 and housing leakage air flow class B, from nominal diameters 840 × 480 Leakage air flow with closed flap 3 and housing leakage air flow class C
• Integration into the building management system with TROXNETCOM or with interface modules such as SLC® technology
• Cmod for smoke extraction with ventilation function and control characteristics in combined systems (combination flap) and thus pneumatic balancing possible by moving to intermediate positions

Application

• Smoke extraction damper with CE marking and declaration of performance for the dissipation of smoke and heat in smoke extraction systems with mechanical smoke extraction devices
• Can be used in pressure ventilation systems (DBA) with ventilation function, but also for outside air supply (inflow)
• Integration into the building management system with TROXNETCOM or into other standard bus systems possible
