GAC

Product catalog summary

Overview

This technical catalogue details the GAC series of helical electric fans designed for industrial and commercial ventilation. It covers product specifications, applications, performance data, dimensions, terminology, and standards in five languages (Italian, English, French, German, Spanish).

1. Use and Applications

The GAC fans are engineered for extracting fumes, stale, dusty, and humid air in industrial environments such as foundries, cement plants, paper mills, and woodworking shops. They are also suitable for aeration of public spaces and drying processes involving materials like paper, wool, pasta, and bricks. Operating temperature range is specified from -20°C to +60°C. Additional technical details and motor specifications are referenced in separate catalogues.

2. Product Variants and Motor Position

The catalogue identifies four main fan executions distinguished by motor position relative to airflow and design features. Specific model codes correspond to different sizes and motor configurations, allowing selection based on installation requirements.

3. Performance Characteristics

Performance data tables provide parameters at 50 Hz and 60 Hz frequencies, including total pressure (Pt in kgf/m²), power consumption (kW), rotational speed (RPM), noise level (dBA), and airflow volume (m³/min). Key tolerances are ±5% for flow rate and +3 dBA for noise. Conversion formulas for airflow (m³/h = m³/min × 60) and pressure (Pa = kgf/m² × 9.807) are included for clarity.

4. Dimensions and Weights

Detailed dimensional data and weights are provided per fan model, referencing parameters such as diameters (Dp, Db), lengths (C, Cb), number and diameter of bolt holes (nfb, Øfb). Dimensions are based on the A14/A19 motor series, ensuring compatibility and proper installation.

5. Flange and Mounting Specifications

Specifications for suction counterflanges include flange diameters (Dp, Df, Db), hole counts (4 to 24), hole diameters (Øfb), and maximum screw diameters (Øvb) for locking. Metric ISO threads with triangular profile and coarse pitch are used. Screw sizes range from M8 to M10 depending on flange size.

6. Terminology and Symbols

The catalogue standardizes terminology and component identification across five languages. Key components include drum casing (V02), impeller (V11), and motor (V20). Symbols and units conform to international standards, covering airflow (V), total pressure (pt), power (kW), rotational speed (RPM), and noise level (dBA).

7. Standards and Testing Conditions

Fan construction and orientation comply with UNI ISO 13349:2002. Testing follows UNI 10531:1995. Performance data refer to air at +15°C, atmospheric pressure of 760 mmHg, and air density of 1.226 kg/m³. Noise measurements are conducted in free field at 2 meters distance under maximum efficiency conditions, connected to suction and discharge ducts, according to UNI EN ISO 3740, 3744, 3746, and 13347 standards. All dimensions are in millimeters. Data tables are indicative and not contractually binding.

8. Critical Information and Recommendations

Maintain operating temperatures within -20°C to +60°C for optimal performance and safety.
Consult the Technical Information booklet for detailed fan selection and usage guidance.
Use the Accessories booklet to identify optional components for customization.
Refer to the Electric Motors catalogue for motor specifications and compatibility.
Consider flow rate and noise tolerances when designing ventilation systems.
Verify dimensions and weights based on the motor series to ensure proper installation.

9. Multilingual Presentation

All technical data, terminology, and notes are presented in Italian, English, French, German, and Spanish to support international users.

This structured information assists engineers and technicians in selecting, installing, and maintaining GAC series fans for diverse industrial ventilation applications.
