In each system, the 7.5kW exhaust fan is powered by a Variable Speed Drive (VSD) in our local control panel. This VSD ties in with the 

Staircase Pressurization System The STAIRCASE PRESSURIZATION SYSTEM is made of a axial fan box, frequency converter and air sensor pressure. SMOKE AND HEAT CONTROL SYSTEMS: Specification for pressure differential systems NORM: BS EN 12101-6:2005 This norm specifies the pressure differential systems designed to hold back smoke at a leaky physical barrier in a building, such as a door or other

SAMPLE OF CALCULUS FOR SMOKE AND HEAT CONTROL IN AN OFFICE BUILDING The first step is to define the class system. In this case, it is an office then the class system is C. Stair to pressure Stair to pressure Section Section A-A A-A Section B-B Section B-B Once that the system is defined, we will apply the airflow and pressure difference criterion.

STAIR PRESSURISATION CONTROL SYSTEM Stair well pressurization seems simple enough, just throw in a fan, a pressure transducer and away you go. This may be OK for small stair wells but when you have a tall building with many levels it can be a lot trickier than it looks.
