Exhaust air box during the installation of central air conditioning in today's high temperature centrifugal wind chassis, has been widely used. There are fire smoke wind chassis type and ventilated types. Fire smoke type with high temperature structural panels, motors and drive components are positioned in the wind outside the chassis side, can be discharged flue gas temperatures above 280 ℃ more than 100 minutes of continuous operation. The so-called exhaust air box, in fact, HTF exhaust fan fire, but the fire exhaust fan installed on the basis of a hungry tin trunk. Different wind pressure difference between the two is on the periphery of the tin trunk, after the addition is surrounded by exhaust fan HTF produced. Both are connected to the duct, were sent to the exhaust. Compact appearance HTFC (DT) series low noise fire ventilation (dual) tank centrifugal fan features 1. Structure. Box with frame, box board assembly design. Framework uses advanced metal forming cold-formed unit time stretching, box board duplex board structure, inner silencer material DBF centrifugal wind chassis, further reducing noise. 2. Provide a different import and export orientation centrifugal wind chassis to meet different user needs to install. Using mold production, high dimensional accuracy, can be assembled after the break. 3. The main components of the fan impeller centrifugal digest two-speed exhaust air box, absorbing foundation of the US industrial company's products on LAU, all with mold production. For the wing front curved blade impeller with high efficiency, low noise, large air volume, stable, stable quality, durability and other characteristics. Spiral of high quality galvanized sheet steel or carbon steel plate, mechanized production.
