Smoke Control Damper

layer

EK-JZ


Rectangular smoke control dampers with ventilation function, low installation depth and large cross section for heat and smoke exhaust with mechanical smoke extract systems, for the provision of additional supply air and for use in pressure differential systems

  • Nominal sizes 200 × 230 – 1200 × 2030 mm, for smoke gas flow rates up to 29230 m³/h or 105235 m³/h at 12 m/s, upstream velocities up to 20 m/s possible 
  • Simple and quick installation in and on components
  • Casing, damper blades and actuator encasing made of calcium silicate
  • Pressure level 2 (operating pressure -1000 to 500 Pa)
  • Automatic release (AA), option of manual override (MA)
  • For smoke extract ducts from 35 mm wall thickness
  • Closed blade air leakage to EN 1751, class 3
  • Casing air leakage to EN 1751, class C


Optional equipment and accessories

  • Cover grille (various constructions)
  • Connecting subframe for calcium silicate and sheet steel smoke extract ducts
  • Integration into the central BMS with TROXNETCOM
  • Coating for use in exterior walls
  • Cmod = for smoke extract and ventilation in combined systems, which allows for pneumatic volume flow rate balancing as the damper blade can take intermediate positions
  • Installation accessories

EK-JS

Rectangular sheet steel smoke control damper including ventilation function for the removal of smoke and heat in smoke extract systems, as well as for the controlled flow of the necessary supply air. Suitable as a support for keeping safety rooms and their anterooms smoke-free in pressurised ventilation systems (DBA), e.g., in fire brigade lift shafts or for smoke removal in escape tunnels.


  • Can be used in discharge environments with elevated temperatures of up to 600 °C at tested smoke extract ducts and sheet steel ducts
  • Meets pressure level 3 with any airflow direction and automatic release (AA)
  • Nominal sizes 100 × 100 – 1250 × 2560 mm
  • Volume flow rate of 360 m³/h or 100 l/s – 115110 m³/h or 31975 l/s at 10 m/s
  • Design in sheet steel (also powder-coated according to RAL-CLASSIC chart) or stainless steel sheet in A4 quality
  • According to EN 1751: Leakage air flow with closed damper at least class 2 and casing leakage air flow class B, from nominal sizes 840 × 480 leakage air flow with closed damper 3 and casing leakage air flow class C
  • Integration into the central BMS with TROXNETCOM or with interface modules such as those in SLC® technology
  • Cmod for smoke extraction with ventilation function and control characteristics in combined systems (combination damper) and therefore pneumatic balancing possible via travel to intermediate positions

EK-JZ SMOKE CONTROL DAMPER: UNIVERSAL. MODULAR. SAFE. 

Smoke control dampers with the largest possible openings are required to keep escape and rescue routes smoke-free.

This is the only way to achieve large volume flow rates at low airflow velocities – a prerequisite for the effective functioning of pressure differential systems (DBA).
