 Colt Smoke Control: Pressurisation

Pressurisation systems for smoke and fire ventilation < back to all smoke control systems

A pressurisation system consists of three main components: Supply Air (where air is injected into the area that is to be protected), Pressure Relief (to avoid overpressure when doors are closed) and Air Release (air and smoke is released from the adjoining fire area). Combining these elements creates a positive pressure difference that prevents lobbies and staircases from filling up with smoke.

A pressurisation 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".

Contact Colt for more detailed information on pressurisation systems and what the requirements are for your project.
