Radial Roof Fans

Product catalog summary

Overview
The document provides comprehensive technical specifications and features of Rosenberg roof fans, designed for ventilation in various environments such as department stores, supermarkets, and factories. These fans are adaptable for installation on different roof types and are available in both horizontal and vertical discharge models.

Types and Features

Type DH: Horizontal discharge suitable for less polluted air.
Type DV: Vertical discharge designed for heavily contaminated air, available in a swing-out version.

Casing and Impellers

DH covers up to size 500 are made from seawater-resistant aluminum, while sizes from 560 are made from galvanized sheet steel.
DV casings are constructed from seawater-resistant aluminum.
Impellers are backward curved, made from plastic up to size 450, and from aluminum for larger sizes, dynamically balanced according to DIN1940 standards.

Motors and Electrical Connection

Motors are voltage controllable, with humidity protection and thermal contacts embedded in the windings.
Protection class ranges from IP44 to IP54 depending on the size.
Motors include a built-on terminal box for straightforward electrical connection.

Performance and Noise Levels

Performance curves show pressure increase as a function of airflow.
Noise levels are specified with A-weighted sound power levels for both inlet and outlet sides.

EC Roof Fans
EC roof fans feature integrated control systems, pressure sensors, and backward curved impellers, offering energy savings of up to 35% compared to AC types and allowing for simple system adjustments.

Technical Data and Accessories
The document includes detailed technical data, wiring diagrams, and sound level measurements for various fan sizes, along with a list of available accessories.

Specifications
Each fan model is detailed with voltage, power consumption, current, speed, protection class, insulation class, and weight. For example, the DV/DH 310L-6 D operates at 400V with a power of 0.09 kW and a speed of 1000 min-1, while the DV/DH 400-4 E operates at 230V with a power of 0.52 kW and a speed of 1385 min-1.

Sound Levels
The document provides A-weighted sound levels at various frequencies for both the inlet and outlet sides of the fans.

Dimensions
All dimensions are provided in millimeters, with diagrams and tables illustrating the physical dimensions of the fans.

Wiring Diagrams
Detailed wiring diagrams are included for each fan model, indicating the color coding for wires and connections for high-speed operation.

Accessories and Additional Information
The document references additional pages for accessories and further technical details, such as attenuation values and pressure losses for fans with integrated sound-absorbing covers.

Key Features

Vertical and horizontal discharge options.
Motor protection through thermal contacts.
Speed variability using auto transformers.
Designed for both vertical and horizontal installations.

Performance Data
Performance data is provided in terms of airflow (m3/h and C.F.M.) and pressure (Pa and in.WG) for different fan models, illustrating their efficiency and operational capabilities.

Recommendations
The document suggests best practices for installation and operation, emphasizing the importance of adhering to the specified electrical and mechanical parameters to ensure optimal performance and longevity of the fans.
