Smoke Ventilation System
Smoke Ventilation Systems are naturally ventilated systems using smoke ventilators or power exhaust systems using fans, dampers and ductwork.
The Merlin Ventilator
The Merlin ventilator is designed for smoke ventilation that can either be wall or roof mounted. The Merlin is an operable Louvered Ventilation System.
The “Merlin” ventilator has excellent day lighting characteristics obtained using durable, tough and UV light resistant triple wall polycarbonate material. Polycarbonate also retains its physical properties of strength and impact resistance down to extremely low and up to high temperatures. The body and blades of the ventilator can be manufactured with integrated aluminium foil-faced rigid foam to give a U value of 0.6W/m2C. The “Merlin” ventilation units are designed and tested to meet the requirements laid down in current codes of practice. Fire tests have been carried out at a leading UK Fire Research Centre in accordance with BS 7346: Part 1 1990. Climatic performance testing, in accordance with CP3: chapter V: Part 2. The smoke ventilation units’ meet the snow load requirements as laid down in BS 6399: Part 3. 1990. Rain and wind penetration tests have been carried out using Zefyr’s own laboratory facilities which include an outside weathering rig, vacuum rig and aerodynamic test chamber designed by Loughborough University department of technology. All testing has been carried out in accordance with BS 7346: Part 1 1990.As an optional extra the ventilator can have actuator systems (manual, pneumatic or electrical operation), bird guards, burglar guards, fusible link shields, closure flashings and windshields.
Swift Flap Ventilator
The Swift smoke vent is an operable flap ventilation system that can be mounted to the roof or the wall. The roof unit is supplied as a two-part assembly; a base and a builder's stand-up.
The Swift ventilation units are designed and tested to meet the requirements laid down in current codes of practice. Fire tests have been carried out at a leading UK Fire Research Centre in accordance with BS 7346: Part 1 1990. Climatic performance testing, in accordance with CP3: chapter V: Part 2.
