Product catalog summary

Roof Extract Fans DV

Product Review: The DV series fans are designed for both vertical and horizontal discharge of slightly polluted air. They feature integral drive motors with thermal protection and are constructed from galvanized sheet steel with aluminum impellers.
Specifications: These fans operate within a temperature range of -20°C to +40°C and come with isolator switches. They are available in various sizes, with performance ranging from 445 to 34,550 m³/h.
Safety and Standards: Compliance with DIN EN 294 safety standards is ensured, with additional inlet guards required if accidental contact with the impeller is possible. Performance data is measured according to DIN 24 163-2, and noise levels are evaluated per DIN 45 635 - 38.
Sound Data: Sound power levels are provided for both intake and discharge, with recommendations for duct configurations to minimize noise and pressure losses.

Ventilation Hoods DLH

Product Review: Details on dimensions and pressure drops for intake and exhaust are provided, along with accessory dimensions.

Smoke Extract Fans ER

Product Review: Similar to the DV series, these fans are designed for smoke extraction with specific performance and dimension data provided for various models.
Specifications: Includes isolator switches and accessory dimensions, with sample specifications available for reference.

Overview: The document provides detailed technical specifications and data for roof ventilation hoods and smoke extract fans, focusing on their design, performance, and compliance with safety standards.

Roof Ventilation Hoods DLH:

Constructed from galvanized sheet steel, these hoods serve as weatherproof ventilation openings or as terminal elements in ventilation systems.
Key dimensions and pressure loss data are provided for various models (DLH 40, 56, 71, 90, 125).
Accessories and additional components are detailed, including dimensions and specifications for different configurations.

Smoke Extract Fans ER:

Designed for heat and smoke extraction during fires, these fans help maintain smoke-free escape routes and facilitate firefighting.
Models RDM 56 and RDM 57 are certified to meet EN 12101-3 standards, with temperature resistance up to +600°C for 120 minutes.
Technical data includes flow rates, pressure, voltage, speed, motor specifications, and sound power levels.
Safety features include compliance with DIN EN 294 for safety guards and DIN 24 166 for technical specifications.

Performance and Safety:

Performance curves and sound data are provided, with emphasis on noise levels and attenuation across different frequencies.
Installation and maintenance guidelines stress the importance of adhering to safety standards and using heat-protected cables.

Overview: The document provides detailed technical specifications and operational guidelines for various models of smoke extract fans, specifically the RDM 56/57 series. It includes information on flow rates, pressure, voltage, motor speed, and sound levels, as well as dimensions and installation instructions.

Specifications: Each fan model is described with its flow rate in cubic meters per hour (m³/h), available pressure in Pascals (Pa), voltage rating, motor speed in revolutions per minute (1/min), power consumption in kilowatts (kW), current in amperes (A), and weight in kilograms (kg). The document also specifies the isolator switch model for each fan.

Sound Levels: The A-weighted sound power level (LWA) is provided for each fan model, measured according to DIN 45635-38 standards. The document includes sound attenuation data for silencers at various frequencies, indicating the reduction in decibels (dB).

Installation and Dimensions: Detailed dimensions for each fan model are provided, including information on flat roof upstands, flexible connections, mating flanges, and silencers. The document specifies the pressure loss through silencers at different flow rates.

Operational Guidelines: The document outlines the function of isolator switches, which are used to safely disconnect the fan from the mains for maintenance. It also describes the optical smoke detector EBS 02, which detects smoke using the Tyndall effect and includes a temperature sensor for additional safety.

Standards and Certifications: The smoke extract fans are tested and certified according to EN 12101-3 and DIBt standards, ensuring they are suitable for high-temperature operations up to 600°C for 120 minutes.

Specifications:
The document describes a centrifugal impeller with backward curved blades made of steel, which are welded and coated. All mechanically stressed parts are made of galvanized sheet steel. The motor is separated from the air stream and cooled by outside air, with additional thermal isolation in the motor cabinet.

3 Roof Extract Fans DV Technical Description Motors Well tried and tested integral drive motors are used. Noise-tested, maintenance-free deep-groove ball bearings give the motor long life. To avoid overheating, every motor is equipped with thermal contacts. This thermal protection has to be effective in operation in order to enable the user to claim for warranty in the case of break down. Please follow the instructions of the wiring diagram for connecting the thermal contacts correctly. Fan range DV 40-125 The fans of the range DV 40 - 125, for vertical discharge, are suitable for discharging...

5 All roof extract fans are supplied with a discharge-side mesh safety guard in accordance with DIN EN 294. The inlet side is not fitted with a standard guard, because it is normal practice to attach other system parts to the side. However, if the unit is installed in such a way that accidental contact with the impeller is possible, an additional inlet guard has to be fitted acc. to DIN EN 294! The fans may only be put into operation if all necessary protection devices are fitted and made effective (see maintenance instructions)! The safety guards are to be executed acc. to DIN EN 292 – 1, chapter...
