Active smoke-extraction system

CLASS OF FIRE PROTECTION Meets the recommendations of Approved Document B and BS 55885:2004 for ventilation of firefighting shafts

SAFETY FEATURES Provides equivalent performance to a BRE shaft. The Colt Shaft design has been proven by extensive CFD analysis and by empirical tests

CHARACTERISTICS A mechanical smoke shaft system suitable for use in any fire-fighting core. It requires only 20 per cent of the floor space required by the traditional BRE shaft. Pressure sensors to each lobby prevent ventilation systems causing negative pressure and making doors difficult to open

SPECIAL PROPERTIES The Colt Shaft opens up the space on each floor, which allows architects to be more creative in their design, and increases the saleable or lettable space in commercial buildings for the client
