Product catalog summary

General Principles of Fan Design

Parameters: Key parameters for fan design include capacity (volume of fluid moved per unit time), pressure (sum of static and dynamic pressures), efficiency (ratio of energy output to input), and speed of rotation. These parameters are crucial for determining fan performance.
Efficiency: Calculated using the formula η = (V * pt) / (1.02 * P), efficiency measures the effectiveness of the fan in converting energy input into useful work.
Speed of Rotation: Affects capacity, total pressure, and absorbed power, with specific formulas provided for calculating changes due to speed variations.

Sizing: Fan characteristics are standardized based on operation with air at +15°C and 760 mm Hg barometric pressure. Adjustments are necessary for variations in specific gravity.

Technical Features

SPM Series: Features steel casing and aluminum or resin blades, suitable for environments like foundries and cement plants. Capacity ranges from 240 to 33,600 m3/h with total pressure up to 115 daPa.
SPMD/SPMDR Series: Equipped with adjustable blades for polluted air extraction, with capacity ranging from 2,100 to 150,000 m3/h and total pressure up to 165 daPa.
SI/SIR Series: Designed for ducted applications, featuring a long casing and inspection door. Capacity ranges from 240 to 150,000 m3/h with total pressure up to 165 daPa.

General Notes: Motors comply with IEC standards, and standard painting is blue RAL 5007. Special executions are available upon request.

Performance Parameters:
Key parameters such as flow rate, pressure, efficiency, and rotational speed are outlined, explaining their interrelation and impact on fan performance.

Environmental Considerations:
A table shows the specific weight of air at various temperatures and altitudes, crucial for calculating performance under different environmental conditions.

Design and Application:
Fans are designed for easy integration into systems like exhaust plants and ventilation systems for tunnels and subways, suitable for applications requiring large flow rates and low pressure values.

Overall Dimensions and Weights
Dimensions and weights of various motor types are provided, including a non-binding table with fan weights in kilograms, including the motor. The standard painting color is RAL 5007, and the temperature range for conveyed fluids is -10°C to +60°C.

Specifications
Various motor types are listed with their respective RPM, noise levels in dB(A), and installed power in kW. A detailed table of static and total pressure values (Pst and Pt) for different motor types and configurations is included.

Materials
Blades are made from either resin (glass-charged polypropylene) or aluminum, emphasizing the material options for the blades.

Tolerances
Tolerances for capacity (±5%) and noise (+3 dB(A)) are specified.

Additional Notes
Some configurations are available only upon request. Multiple tables with detailed technical data for various motor series, including SPM 3000 rpm, SPM 450/C, and others, are included.
