Pre-Engineered Fans

Howden pre-engineered centrifugal fans are selected aerodynamically from a range of standard sizes and configured mechanically to meet the customer’s requirements. This allows us to quickly 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 our 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 ancillary 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.

Fans can be supplied in accordance with the major international design and quality standards.
