CB Blower Co. is known for its high qualtity industrial fans of different types, such as: Airfoil Centrifugal Fans are used for a wide range of applications in many industries, hollow-bladed airfoil fans are designed, engineered and tested for use in airstreams where high efficiency and quiet operation are required. They are used extensively for continuous service at ambient and elevated temperatures in forced and induced draft applications in the metals, chemical, power generation, paper, rock products, glass, resource recovery, incineration and other industries throughout the world. Backward Curved Fans – Efficiencies nearly as high as the airfoil design. However, single-thickness metal blades prevent the possibility of dust particle buildup inside the blade. These fans can be built with long-lasting erosion-resistant liners. The robust design allows high tip-speed operation, and therefore this fan is often used in high-pressure applications. This design frequently offers the best compromise for long life and high efficiency. Backward Inclined Fans – Simple flat blades, but backwardly inclined to match the velocity pattern of the air passing through the fan wheel, which results in high-efficiency operation. These fans are typically used in high-volume, relatively low-pressure, clean air applications. Radial Blade Blowers – Flat blades oriented in a radial pattern. These rugged fans offer high pressure capability with average efficiency. They are often fitted with erosion-resistant liners to extend the rotor life. The housing design is compact to minimize the floor space requirement. Forward-Curved Radial Tip Fans – This rugged design is used in high-volume flow rate applications when the pressure requirement is rather high and erosion resistance is necessary. It offers medium range efficiencies. A common application is the dirty side of a baghouse or precipitator. The design is more compact than airfoil, backward curved or backward inclined fans. Paddle-Wheel Blowers – This is an open impeller design without shrouds. Although the efficiency is not high, this fan is well suited for applications with extremely high dust loading. It can even be offered with field-replaceable blade liners from ceramic tiles or tungsten-carbide. This fan may also be used in high-temperature applications. Forward-Curve Fans – This “squirrel cage” impeller generates the highest volume flow rate (for a given tip speed) of all the centrifugal fans. Therefore, it is often the smallest physical package available. It is commonly used in high-temperature furnaces. Industrial Exhausters – Relatively inexpensive, medium-duty, steeply inclined flat-bladed fan for exhausting gases, conveying chips, etc. Pre-engineered Fans – are series of fans of varying blade shapes that are usually available in only standard sizes. Because they are pre-engineered these fans may be available with relatively short delivery times. Often, pre-engineered rotors with various blade shapes may be installed into a common housing. These are often available in a wide range of volume and pressure requirements to meet the needs of many applications. Pressure Blowers – High-pressure, low-volume blowers used in combustion air applications in furnaces or to provide “blow-off” air for clearing and/or drying applications. Surgeless Blowers – High-pressure, low-volume blowers with a reduced tendency for “surging” even at severely reduced flowrates. This allows extreme turndown (low-flow) without significant pulsation.
