Product catalog summary
Specifications:
The document outlines the specifications for high-pressure centrifugal fans, detailing flow rates from 300 to 45000 m3/h and pressures from 75 to 2500 mmH2O. Constructed from Fe360 steel, the fans have impellers balanced both statically and dynamically. They operate with standard fluid temperatures between -10°C and +60°C.
Field of Operation:
These fans are suitable for medium-low flow rates and high-pressure applications such as pneumatic transport, dust extraction, drying, and pressurization in industrial settings like foundries, pasta factories, and chemical plants.
Blade Type:
The fans feature curved, backward (negative) blades.
Construction Configurations:
Standard configurations include Arr.1, Arr.4, Arr.5, Arr.8, Arr.9, and Arr.12, with details on pages 21-22.
Operating Specifications:
The fans operate with inlet air conditions at 20°C, 0 m above sea level, and a density of 1.205 kg/m3. Noise levels are expressed as sound power LwA [dB(A)], measured in free field conditions with ducted fans.
Orientations:
The fans are available in 8 RD (clockwise) and 8 LG orientations. Sizes 450-630 are bolted and orientable, while sizes 710 and above are not orientable with transmission drive but are always orientable for directly coupled fans without front support.
Special Applications:
Custom configurations are available upon request.
Fan Start-up:
During start-up, the fan flow rate must be limited to match the fan's maximum electrical input.
Impeller Classes:
A table for standard operating conditions is provided, advising consultation with customer service for heavy-duty conditions to determine the most suitable impeller type.
Performance Data:
Detailed tables of performance data specify maximum RPM for various fan sizes and classes, with values valid up to 60°C. Noise and load tolerances are also provided.
Additional Specifications:
The document also provides detailed specifications for centrifugal fans, including dimensions, weight, and performance curves. Specific models like DVG1400N and DVG1600N are mentioned with their respective dimensions and weights.
Performance Data:
Performance data is presented in tables showing airflow (Q) in cubic meters per second and hour, pressure (Ht) in Pascals and mmH2O, and velocity (v) in meters per second. Noise levels in dB(A) and rotational speeds in RPM are included.
Construction Forms:
Various construction forms for centrifugal fans are described, including direct drive and belt drive configurations. Temperature limits are specified for each form, with maximum air temperatures ranging from 60°C to above 150°C, depending on the presence of cooling fans and thermal insulation.
Recommendations:
The document recommends specific configurations for different operational needs, emphasizing the importance of selecting the appropriate construction form based on temperature requirements and installation constraints.
