正壓送風口

正壓送風口，廣州貴庭機電

廣州市貴庭機電設備有限公司生產的正壓送風口，通常安裝在樓梯前室，防煙井的墻上，也有安裝在防煙系統管道側面或風道末端

當發生火災時，系統內部電動執行器自動打開風口，塔樓定正壓風機自動啟動，對送風豎井進行加壓送風，樓梯的前室通過正壓送風口源源不斷對前室進行送風，使前室保持正壓，保證煙氣不會再這個區域蔓延，從而給人提供逃生的空間，當溫度高于280°C時，人已無逃生可能，正壓送風口熔斷器熔斷，風口自動關閉，防止火災蔓延

國家高層建筑防火排煙設計規范規定，下列位置應設置獨立的機械防煙系統

1、封閉的避難層

2、不具備自然排煙條件的防煙樓梯、消防電梯前室或合用前室

3、采用自然排煙的方友樓梯，當不具備自然排煙的前室

廣州市貴庭機電設備有限公司專業生產消防風機，風閥，風口和消防靜壓箱等防排煙系列產品
