Description

Pressurization system comprising: supply air; pressure relief and air release to create a positive pressure difference that prevents lobbies and staircases from filling up with smoke.


Three main components:

  1. Supply air - where air is injected into the area that is to be protected.
  2. Pressure relief - to avoid overpressure when doors are closed.
  3. Air release - air and smoke is released from the adjoining fire area. Combining these elements creates a positive pressure difference which prevents lobbies and staircases from filling up with smoke.


A pressurization system for smoke and fire ventilation should meet the recommendations of Approved Document B and BS EN 12101-6 "Specification for Pressure Differential Systems" or BS 5588-4 - "Code of practice for smoke control using pressure differentials".
