Lobby Smoke Damper LSD
The LSD lobby smoke damper has been designed to satisfy smoke vent applications and is particularly suited for fire rated mechanical smoke extraction shafts in multi-storey buildings.
The damper has been fire tested to the latest European Fire Damper Test Standard (EN1366-2) and achieved a 2 hour fire resistance performance to ES120.
| Frame | 1.5mm galvanised steel frame with fully seam welded corners along the entire depth to produce a rigid and air tight construction. |
| Damper blades | Vertical “opposed motion” to enhance air entrainment being ‘pulled’ into in smoke shaft.
0.7mm galvanised double skin airfoil 100mm pitch with interlocking engagement when damper is closed. |
| Gasket | 0.40mm type 301st/stl peripheral gasketing around entire perimeter. |
| Drive and linkage | ‘Out of airstream’ mechanism. |
| Ambient leakage | Conforms to class ES of EN1366-2 / ISO10294-2 (200m3/hr/m2 – 55 l/s/m2). |
| Fixing | Pre-punched damper sleeve fixing holes. |
| Sizes | From 400mm x 400mm up to 1200 x 1500 mm. Available in 100mm increments. |
