How to Navigate the Construction Page

The Construction Page of the Halifax Fan Selector provides a comprehensive view of all the design and construction elements for centrifugal fans. This section allows users to configure various fan components according to specific requirements, including fan material, motor design, casing details, and more.

Key Construction Fields

Here is an overview of important construction-related fields and how to configure them:

• Fan Discharge

  • Defines the discharge rotation and direction of centrifugal fans according to the ISO standard (BS EN ISO 13349).

• Motor Mounting Design

  • Select the design for motor mounting based on the fan arrangement and mounting options.

• Casing Construction Material

  • Choose the material used for constructing the fan casing. Common materials include Carbon Steel, Stainless Steel (304, 316, 2205), and Titanium.

• Casing Welding Specification

  • Specify the type of welding used for the casing.

• Casing Design for Impeller Withdrawal

  • Configure the design for impeller withdrawal, which determines how easily the impeller can be removed for maintenance.

• Casing Design Pressure

  • Specify the fan casing design pressure, which is crucial for ensuring the casing can withstand operational conditions.

• Pedestal

  • Select the material used for the pedestal, which supports the fan’s shaft and impeller.

• Impeller Construction Material

  • Choose the material for the impeller, which could range from Carbon Steel to more specialized materials like Wear-Resistant Steel or Hastelloy.

• Impeller Balance Grade

  • Define the balance grade of the impeller to ensure smooth operation and reduce vibrations.

• Shaft Seal

  • Select the type of shaft seal to be used in the fan assembly, ensuring minimal leakage and optimal performance.

• Mechanical Run Test

  • Perform a mechanical run test (vibration analysis) following BS848-7:2003 or BS ISO 14694:2003 standards

Finalising Your Configuration

Once you've configured all the necessary design and construction parameters, ensure that all fields are filled out correctly before proceeding to the next stage. You can always modify or update any configuration before finalising your fan selection.
