It s important for you to learn about both of these types of blades before purchasing a centrifugal fan. The backward inclined fan backward inclined blower is highly efficient because it has simple flat backward inclined blades that minimize interference with the airflow as the air moves through the fan. The backward inclined fan has flat backward inclined blades to minimize airflow interference for high efficiency with lower sound levels and energy costs than other fan types.

The name centrifugal fan is derived from the direction of flow and how the air exits the fan impeller radially from the outer circumference of the fan. Backward inclined fans nyb offers a line of centrifugal air moving products with backward inclined wheels designed to accommodate clean air applications. Two of the most common types of blades are forward curved also known as backward inclined and backward curved. Radial blade the flat blades of this type are arranged in a radial pattern.

Backward inclined fans can be found in forced draft as well as induced draft service for a variety of different industries including chemical and power plants cement pulp and paper foundries and refineries. Backward inclined these fans have simple flat blades backwardly inclined to match the velocity pattern of the air passing through the fan wheel for high efficiency operation. Grainger carries a full line of backward inclined blowers in a variety of sizes and horsepower capacities both with and without drive packages. These rugged fans offer high pressure capability with average efficiency.

Find them at grainger today. Find out more about them below. These fans are typically used in high volume relatively low pressure clean air applications. These high efficiency centrifugal fans feature rugged construction for long life and are useful in industrial ventilation and restaurant and laboratory exhaust systems.

Bae aerofoil fans offer a slightly higher efficiency and less noise than bc fans at a price premium of about 2. There are myriad types of blades that can be used in centrifugal fans and it ll be up to you to pick the one that fits your needs best. It also offers lower sound levels and energy costs than many other fan types and includes a non overloading horsepower design for low pressure applications. Clean air centrifugal fans have the ability to handle a variety of air flows relative to static pressure with some tolerance for dust and moisture.

They are often fitted with erosion resistant liners to. In the example shown below the fan rotates in a clockwise direction. Biw30001100 130 hd s blade9 gussets cw call 212 226 0575 for pricing or. Finally this fan is suited for clean air and or high temperature applications.

The nonoverloading character of backward inclined blowers makes them efficient and cost effective. A backward curved centrifugal fan is characterised by its cylindrical shape several large curved blades and a conical inlet nozzle.
