High-pressure fans are a type of centrifugal fan that is designed to move air or gas at high pressures. They are commonly used in industrial applications, such as in ventilation systems, pneumatic conveying systems, and combustion air systems.

1. Robust construction: High-pressure fans are built with robust materials, such as heavy-duty steel, to withstand the high pressures they are designed to handle.

2. High pressure capacity: These fans can handle pressures up to several inches of water column (in.wc) or pounds per square inch (psi), making them suitable for applications that require high-pressure air or gas flow.

3. Efficiency: High-pressure fans are designed for high efficiency, which means they can move a large volume of air or gas while consuming relatively low power.
