圓形管道風機系列是結合國內外先進技術而設計的新型風機 , 進風口和出風口外形尺寸相同 , 風機直接與風管連接, 能夠極大地節省管道設計及安裝費用；新型設計的機殼以及依照空氣動力學設計的葉輪，能夠減少振動和噪音。適用於酒店、賓館、高級會場、超市、貯藏室、洗手間等地方的送風、排風、回風、補風和過濾。

Circular duct fans series are combined with domestic and foreign advanced technology on design. The sizes of inlet duct and outlet duct are the same. Connected the fan and piping directly could save design and install cost on the piping and please Fig.1.Special housing could reduce noise and vibration, best design on the impeller base on aerodynamics. Design for blow, exhaust, circle, renew and filtration could be used in hotel, marketplace, gymnasium, supermarket, store room and most of public place.

單個圓形管道風機的重量均不超過 9 公斤，隻需一個人就能輕易地移動圓形管道風機，方便安裝。

No appliance of this range weighs more than 9 kg, so that one person alone can conveniently move and install them.

2.產品結構Structure

圓形管道風機系列主要由外殼、葉輪、電機、支架和接線盒組成。

Consist of housing, impeller, motor, bracket and connection box.

* 外殼：采用優質熱鍍鋅鋼板制成，具有優良的耐大氣腐蝕性能 ；采用ABS材料獨傢外觀設計（已受國傢外觀專利保護），具有高韌度高延展性，輕便美觀等優點。進風口設計成符合空氣動力學的形狀，便於氣流進入葉輪。進風口和出風口外形尺寸相同，以便於安裝。進風蓋和出風蓋采用螺釘連接，便於維修與清潔。

1) Housing: Galvanize steel sheet material could be able to bear corrosive. And ABS housing with good flexibility, light to use and the characteristics of beautiful. The best design for inlet is based on aerodynamics so that the airflow can easily enter into impeller. Same size for the inlet and outlet can install conveniently. Bolt connection for inlet cover and outlet cover ensure easy maintenances and cleanness.

*  葉輪：  均設計成後向式葉輪，在正常運轉的情況下，均能與外殼良好配合，風量大 , 效率高 , 噪音低。葉輪與外轉子電機構成整體 , 成為葉輪輪轂的驅動電機被氣流高效地冷卻，可以延長風機壽命。

2 ) Impeller: All of Impeller are designed backward curve with big flow, high efficiency, lower noise. The impeller is integrated into the external rotor motor so that the motor is equal to a wheel hub. So the motor can be cooled by the airflow efficiently to prolong life.

* 電機：采用外轉子單相異步電動機，通過 CE 認證、 CCC 認證、 UL 認證。該電機的特點是葉輪直接壓裝在電機外殼上，由電機外殼旋轉直接驅動，機電一體，結構合理，體積小，節省安裝空間；重量輕，運行平穩，效率高，壽命長。

3 ) Motor: External rotor single-phase asynchronous motor received CE ， CCC ， UL certification. The characteristics of the motor are: The impeller is installed on the external casing of the motor directly and is drived by motor directly. The impeller and the motor are combined to a whole with small volume and litter install space;  Mini size, reliable performance, high efficiency and long life.

* 接線盒：采用加有阻燃成分的 ABS 材料制成，防火性能較好。安裝在整機外表麵，接線、拆裝非常方便。

4 ) Connection Box: Made of ABS contained material which can prevent burning. It is installed outward apperance and connecting wire and packing is very convenient.
