CB Blower centrifugal ventilators and fans are found throughout the world operating in industrial processes where performance, reliability and maintainability are of paramount importance. Ranging in diameter from 12" to over 96", and with a variety of impeller designs, control systems and layout options, they form a comprehensive series of centrifugal fans to satisfy virtually all industrial applications.

The majority these centrifugal fans and blowers can be grouped into three broad categories; custom engineered, pre-engineered and OEM. All are supplied to the same exacting standards.

CB Blower pre-engineered centrifugal fans are selected aerodynamically from a range of standard sizes and configured mechanically to meet the customer’s requirements. This allows to provide a cost-effective solution to moving air or gas where the additional cost of a custom engineered fan is not justified either by higher efficiency or mechanical strength. Centrifugal fans store significant amounts of energy when running, and if the fan is not correctly matched with the operating conditions the consequences for the plant operator ...
... can include excessive power consumption, noise generation or mechanical failure, resulting in a significant loss of revenue.

Each of CB Blower designs has been exhaustively tested, aerodynamically and acoustically. The mechanical design is supported by modern analysis techniques, such as finite element analysis. Many options are available in terms of drive arrangement, output control, layout and auxilliary equipment, to give flexibility to the plant designer. All major impeller configurations are supplied including aerofoil, backward curved, backward inclined and radial tipped blade designs.

CB Blower custom engineered centrifugal fans are designed specifically for each contract which allows us to apply a combination of experience, advanced design techniques and a knowledge of the operating conditions to select the optimum fan in terms of capital cost, running cost, maintainability and reliability. Large centrifugal fan rotors store significant amounts of energy when running. If the fan is not designed and manufactured correctly, and matched with the operating conditions, the consequences for the plant operator can include excessive power consumption, noise generation, vibration and mechanical failure, resulting in a significant loss of revenue.

Each of centrifugal blower or fan designs has been exhaustively tested, aerodynamically and acoustically. Empirical design formulae that have been validated over many years are backed up with modern analysis techniques, including finite element analysis, dynamic response analysis and computational fluid dynamics.

It is this combination of knowledge and experience that has resulted in CB Blower becoming a global market leader in heavy-duty centrifugal blowers and fans.
