What is B4-72 centrifugal fan? What is 4-1/B4-72 5A centrifugal fan? This type of 4-72 includes 4-72A, 4-72B, 4-72C, and 4-72D. What does ABCD mean for these four types? Are there four rotation modes on this ABCD? Next, let's take a look at the customer service introduction of the centrifugal fan manufacturer.

Type A is mainly driven by direct motor connection, while Type B is driven by a belt pulley between two support points, while Type C is driven by the motor through a bearing box belt, and Type D is driven by the motor through a bearing box coupling. The centrifugal fan of type 4-72 cannot have this viscous substance in the airflow, and the dust and particulate matter it contains are regulated per cubic meter, as well as the airflow temperature. In this start-up operation, the operation is balanced, the vibration is small, and the usage time is relatively long, which is used for indoor ventilation and exhaust in many buildings. General use: pipeline dust removal, spray paint room exhaust, painting equipment, shot blasting equipment, cement machinery.

This affects the selection of centrifugal fans of class 4-72, regardless of the model chosen, including the speed, motor, flow rate, and total pressure. The 4-72 centrifugal fan is used for indoor ventilation and air exchange in general factories and large buildings, and can be used as both input gas and output gas. Air and other gases that are non flammable, harmless to human health, and non corrosive to steel materials. The outlet position of the fan is represented by the angle of the air outlet of the casing. The user shall install it in the required position according to the requirements, and it is not necessary to specify it when ordering. What is B4-72 centrifugal fan? The B4-72 fan can be used for ventilation and exchange of flammable and volatile gases. There must be no viscous substances in the gas, and the content of dust and hard particles should not exceed 150mg/m. The gas temperature shall not exceed 80C. The performance, selected components, and foundation dimensions of B4-72 fan shall be consistent with those of 4-72 fan, and can be selected according to its sample. In addition, the F4-72 centrifugal fan is mainly used to transport corrosive gases, but the gas transported must not contain viscous substances, dust and hard particles not exceeding 150mg/m3, and the gas temperature must not exceed 80 ° C. The F4-72 centrifugal fan is made of stainless steel, fiberglass or other corrosion-resistant materials, and its performance and foundation size are the same as the 4-72 centrifugal fan.

Kind reminder: What is B4-72 centrifugal fan? There are many models of centrifugal fans, and the range of use for different models of centrifugal fans also varies to some extent. For centrifugal fans, the 4-72 centrifugal fan is a relatively common model. Regarding the fan, it is necessary to search for the brand, model, material, fan pressure, airflow direction, voltage, type, performance, purpose, weight, scope of application, matching motor power, air volume, speed, etc. The B4-72 centrifugal fan described in the article is mainly composed of impellers, casings, air inlets, and motors. It can ventilate and exchange flammable and volatile gases. It is made of stainless steel, fiberglass, or other corrosion-resistant materials to form impellers, casings, air inlets, and motors.
