3.铝制文丘里进风口，旋压一体成型， 有效保证弧形曲线，气流更顺畅，效率更高；
4.电机腔盖采用凸圆式设计理念，有效的增加强度，并减少雨雪或者灰尘的积累；
5.风帽采用弧线型设计，气流更顺畅，降低气流引起的噪音；
6.电机和驱动部件位于气流之外，不与污染物接触，有效降低气流中的污染物影响电机和驱动部件使用寿命；
7.全铝制结构，选择材质高于标准设计5倍的强度要求，有效减少屋顶承重，适合钢结构厂房；
8.材质可选防腐喷涂，耐中性盐雾腐蚀，广泛应用于沿海地区；
9.叶轮平衡等级达到G2.5,整机振动小，有效避免风机振动对屋顶的影响；
10.标配不锈钢螺栓及不锈钢防鸟网。
Model:RTF （Aluminum Roof Centrifugal Exhaust Fan ）
Volume:500~50,000 m³/h
Static pressure:100~900Pa
Weight:35~200kg
Applications:General exhaust, Explosion-proof exhaust and Fire exhaust
Characteristics:
1. With new design of concept, aluminum centrifugal impeller is simulated by the CFD flow field to offer more stable performance;
2. The die stamping process is adopted and the mold tooling is positioned to ensure the accuracy of blade size and angle;
3. Aluminum venturi effectively guarantee the arc curve, providing higher efficiency;
4. The motor chamber cover with convex type design, to effectively increase the strength,avoiding accumulation of dust or rain and snow;
5. Arc type hood increases the intensity, providing higher efficiency and lower noise;
6. The motor and driving parts are out of the air flow without air pollution, providing longer service life;
7. The whole aluminum structure，the material is 5 times higher than the standard in strength, can effectively reduce the load bearing of the roof. It is suitable for the steel structure workshop;
8. Anticorrosion coating is optional, resistant to neutral salt fog corrosion.It is widely used in coastal areas;
9. Wheel balance level up to G2.5 provides less vibration,effectively avoiding the effect of fan vibration on the roof;
10.Stainless steel bolts and stainless bird screen are standard.
