The performance, options and foundation size of B4-72 centrifugal fan are the same as those of 4-72 type, which can be selected according to its sample. The fan mechanism is basically the same as the 4-72 type. NO.2.8--6A uses a B35 motor with a flange and a ground foot. NO.6--12C and D motors use the YB series corresponding to the Y series in the table. , The installation form is B3.
F4-72 anti-corrosion centrifugal fan is made of stainless steel, glass fiber reinforced plastic or other corrosion-resistant materials. It is suitable for installation and use in chemical plants, laboratories, basements, baths and other occasions. It is used to transport corrosive gases, acid and alkaline gases and high humidity gases .
The inner surface and built-in parts of the clean-type purification air-conditioning unit shall be selected from corrosion-resistant materials or surface layers, and the material surface shall be smooth and clean. The internal structure should be easy to clean and the cleaning wastewater can be smoothly eliminated, and it is not easy to accumulate dust and breed bacteria.
It is mainly used in intermediate filtration of central air-conditioning ventilation system, pharmaceutical, hospital, electronics, food, and other industrial purification. It can also be used as high-efficiency front-end filtration to reduce the load of high efficiency and extend its service life. Due to the large windward side, Therefore, the amount of air dust is large and the wind speed is low, which is considered to be a better medium-efficiency filter structure at present.
WX type micro-perforated plate muffler features: the micro-plate muffler is a dual cavity type, composed of two layers of micro-perforated plates with different perforations, and the air column at the neck of the small hole on the plate and the air in the cavity form a plywood sound absorption mechanism When the frequency of the external noise and the natural frequency of the elastic system are the same, it causes the air at small apertures to strongly resonate, which causes severe friction and consumes sound energy. The micro-plate muffler is particularly suitable for attenuation of low-frequency noise.
