Positive pressure ventilation (PPV), are ventilation systems that stop the spread of smoke through buildings to increase the likelihood of safe evacuations in the event of a fire.
The Smoke Control Association (SCA) regulations dictate that lobby ventilation is required either by natural ventilation or mechanical smoke control systems and how to meet these standards.
How It Works
The system works by driving air into a lobby or stairwell, moving high-pressure air into low-pressure areas, forcing smoke out of the communal areas meaning people can evacuate safely.
The unit is operated by a smoke detector and will continue to run until it is reset.
This reduces the risks during a fire as people will be able to vacate the building safely.

What a Unit Contains
The PPV unit contains duty and standby fans, duty and standby fire dampers, a smoke detector interface, single phase automatic electrical change over switch, controls, status LED and a volt free contact for 3rd party monitoring.
The primary benefit of the PPV unit is evacuating smoke in the event of a fire meeting safety regulations and ensuring compliance. However, other benefits include: the unit takes up minimal space, are relatively cheap to buy and install causing little disruption to your building and the units can be used for buildings or car parks.
