When choosing a ventilation system for a new industrial-grade workshop, most people understand that centrifugal fans are the best. It is because centrifugal fans, popularly known as blowers, are best suited for high-pressure applications, such as sandblasting workshops. However, centrifugal fans come in various blade configurations, each suited for specific industrial applications. Therefore, you must match blade configuration with a workshop's ventilation needs. Here are the blade configurations you should expect to find in industrial fans.

Backward Inclined Fan

This type of centrifugal fan features three unique blade types: flat single thickness, curved single thickness, and curved airfoil. The blades are characteristically big and heavy and rotate in the opposite direction of a fan's wheel. Most importantly, it allows a fan to generate medium to high airflow pressure, making the blade configuration ideal for low-pressure, high-volume industrial applications. Additionally, backward inclined centrifugal fans move at very high speeds compared to other industrial fans. It is an advantage because high operating speeds achieve better centrifugal efficiency.   

Radial Blade Fans

Another type of blade configuration found in centrifugal fans is the radial blade. This type of blade configuration features equally spaced paddle-like blades originating from the central impeller and extending perpendicularly to a fan's wheel direction. Radial blade fans are high-pressure systems powerful enough to efficiently move large amounts of combustion air, gases and dust. Notably, their rugged construction makes them the best choice for harsh industrial environments. Another advantage of radial blade centrifugal fans is their ease of maintenance, thanks to the self-cleaning characteristic of the blade design. Thus, it is a welcome attribute for industrial facilities concerned about high operational costs. The best part is that radial blade centrifugal fans are affordable compared to other fans, making them a budget-friendly option for cost-cautious facilities.

Aerofoil Blade Fans

It is one of the quietest industrial centrifugal fans in the market, thanks to its classic airfoil design. The low noise property of the fan configuration also comes from the hollow blades that reduce stress on the impeller by a significant degree. In addition, the blades have a characteristic twist, which also plays a crucial role in reducing noise levels. The twisted shape eliminates vortex shedding, which is often the cause of noise in industrial fans. In addition, the twisted shape of aerofoil blade fans helps with low power consumption. During operation, air attacks the blade's leading edge, splits and is deflected as it travels along the fin's convex curvature. As a result, it puts minimal pressure on the rotational action of the blades, ensuring low power consumption.
