The 7.5kw air blower
uses a wide-voltage dual-frequency motor, which can be immediately adapted to various voltages without alternating placement; 50Hz-60Hz AC is very convenient for export customers and gives full play to its performance. Small size but large air volume, low noise but high pressure, no manual duty, no maintenance, product operation is quiet and stable, strong and durable.
In addition, the 7.5kw air blower is divided into single impeller and double impeller, and the double impeller is divided into series and parallel, which leads to the same power, but the flow rate and pressure are different. It can be selected as required, and specific performance needs to refer to specific operating curve.
The specific blower model and performance parameters are shown in the following table:

We are making grain skewers and have ordered with many manufacturers. The quality and price are uneven. Each one is good and what is the matter. After the delivery of this fan, it is worth the money. The price is also possible. It is already very satisfactory to have such a material. It was also selected after several comparisons. The price of this one is also very favorable. I received my baby for a few days. The workmanship is very satisfactory, the wind is very strong, I like the color, the feel is good, there is no noise, the effect is very satisfactory, in short, very good!
Re: There are many customers in the Northeast, and there are many in this industry. The amount is also acceptable. The quality and price requirements are relatively high, and it is not easy to weigh. The quality of our fans is generally high-end and not easy to damage. However, pay attention to clean up the filtering equipment frequently, do not accumulate too much, affect the effect of grain suction and affect the operation of the fan. Like your industry, there are many problems that occur because some details have not been noticed.
