消防排煙風機首先應該滿足溫度和時間的特性，即國家規定280℃/0.5h；其次，在一般環境溫度下，可以保證有效的排煙控制量。此外還要求消防排煙風機能夠進行周期性的實驗，能夠發現其中的不足，并加以改進；可以適用各種通風要求的管道，便于安裝與使用。消防排煙風機的性能優良、耐高溫性能良好、效率高、占地比離心風機少、高溫性能優良。消防排煙風機能在300℃高溫條件下連續運行60分鐘以上，100℃溫度條件下連續20小時不損壞，值得信賴的排煙管道應用范圍廣，可根據高級民用建筑的不同要求，采用變速或多速的驅動型式，消防排煙風機廣泛應用于高級民用建筑、烤箱、地下車庫、隧道等場合。排煙管道價格安裝方(fang)便(bian)，可直接和墻壁安裝，安裝可采用(yong)垂(chui)直式(shi)、水平式(shi)或吊裝式(shi)，很大程度上(shang)節省了(le)占(zhan)地面積。
