Differences Between Forward-Curved and Backward-Curved High-Temperature Medium-Pressure Fans

Differences Between Forward-Curved and Backward-Curved High-Temperature Medium-Pressure Fans

There are many types of high-temperature medium-pressure fans, including forward-curved and backward-curved models. These two types of fans differ not only in name but also in their actual performance. To help you understand these differences, I will provide a detailed introduction to both types. 1. Forward-Curved High-Temperature Medium-Pressure Fans: 1.1. Construction: Made by bending two sections of high-quality steel plate. Advantages: Low cost, low speed, thin shaft, small bearings, and a wide operating range. 1.2. Disadvantages: The shape of the performance curve may run parallel to the resistance curve of the ductwork, and a decrease in system static pressure may lead to motor overload. Additionally, the blade structure has low strength and operates at high speeds.
