Why is the price of high-pressure roots blower more expensive than that of ordinary roots blower?

Why is the price of high-pressure roots blower more expensive than that of ordinary roots blower? There are many types of Roots blowers, no matter their models or structural forms. Many characteristics of high-pressure Roots blowers have always attracted attention in the market. What is a high-pressure Roots blower? At present, the roots blower with a boost value greater than 49KPa is generally regarded as a high-pressure roots blower in the industry, and the high-pressure roots blower is one of the roots blowers. The high-pressure Roots blower is generally more expensive than the low-pressure Roots blower, and many people have no idea why. Today, we summarize the following four points:

1. Pressure

The higher the pressure, the higher the performance requirements of Roots blower. Therefore, in the face of higher pressure, higher quality fans are needed to ensure the performance of the blower. Therefore, the price is higher.

2. Structure

For example, the ordinary three leaf roots blower can meet the low pressure, but when the pressure rises, the blower will generate more heat. In order to eliminate these heat, the roots blower needs to be improved to ensure that all parts of the roots blower can operate normally. Therefore, the improved part also needs a certain cost.

3. Performance

In order to ensure the normal operation of high-pressure Roots blower under high-pressure conditions, it needs more excellent performance. For this reason, the more matching processes, the higher the overall cost, because more material costs and time costs are added.

4. Motor

The machine head is of the same model and diameter. Under different pressures, higher power motors are required. The higher the requirements for motors, the higher the price.
