Staircase pressurization fan catalogue. Specification for pressure differential systems norm. Smoke and heat control systems. This is the a staircase in the building. Staircase pressurization as per nbc 2016 designed stairwell pressurization systems in building safety and construction a smokeproof enclosure is a type of exit stairwell that has been designed to keep out smoke and other combustion products in the event of a fire so that building occupants may more safely exit the building.

3 diagram 211 1 example 1 25th storey of a staircase that extends from the 1st storey to the 30th storey of a 30 storey building. Stairwell pressurization fan calculation excel sheets 1062018 102300 pm if there is a fire it causes smoke to spread everywhere so we must keep the smoke away from the escape route. Stair pressurization due to the relative cost of the associated mechanical systems and architectural space issues related to providing exterior balconies and stair vestibules the stair pressurization system is the most widely selected design option. At the top of a stairwell.

Example 2 27th storey of a stairway that extends from the 1 st storey to the 30 th storey of a 30 storey building. The stairway terminates at the roof. Motor class f up to 750 w protection ip 65 more than 750 w ip 55. Bs en 12101 62005 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 similarly restricted openings.

The staircase pressurization system is made of a axial fan box frequency converter and air sensor pressu re. The staircase does not provide access to the roof. In case of fire in a high rise building a stair pressurization fan spf uses clean outside air to pressurize the air in stairwells. When a smoke detector detects a fire in the building the dome opens and the fan is activated.

The pressurized air helps people escape the fire and firefighters battle the fire. Positioned as one of the best and most recognised fan manufac turer in europe. The staircase pressurization system is made of a axial fan box frequency converter and air sensor pressure. Stairways are fire escape routes nowadays stairwells have better fire ratings than the rest of the building.

This catalogue contains just a few of all the options we offer. Box made from galvanised metal sheet with insulation class m1.
