The Maico axial duct fan type DZR20/2B is an industrial ventilation device for installation in ducts with a nominal diameter of DN200. It is operated with three-phase current and serves continuous air movement in ventilation systems, for example in production halls, warehouses or technical rooms. The device is designed for use in ducts, where the axial flow direction moves the air parallel to the rotation axis of the fan.

Axial duct fan is the technical term for a ventilation device that is mounted in a duct cross-section and moves air in an axial direction. The type DZR20/2B is specifically designed for use in ducts with a nominal diameter of DN200, which represents a standard size in ventilation technology. The designation DZR stands for three-phase duct fan, where the digits 20 refer to the nominal diameter (200 mm) and the 2 refers to the construction group or performance level.

Three-phase current as the operating mode means that the fan is connected to a three-phase alternating current network, which is typical for industrial or commercial applications. Three-phase motors offer high operational reliability, consistent rotational speed, and efficient energy conversion, which is important for continuous operating times. The power supply is provided via the network, with no additional power supply units required.

Duct systems are the typical application areas for this fan. It is used in ventilation and air conditioning systems to transport air through ducts. Applications include production facilities where continuous ventilation is required, or buildings with central ventilation technology. The axial flow enables efficient air transport over long duct lengths.

Technology explained simply: The fan operates with an axial impeller that moves air parallel to the rotation axis. The impeller is integrated into a housing that directs the airflow into the duct. The rotational speed is determined by the three-phase motor, which is connected to the network via an electrical connection. The construction is designed for long-term use in industrial environments.

Compatibility and accessories: The fan is designed for ducts with DN200 and can be integrated into existing ventilation systems.

Installation and mounting: Installation is carried out in the duct with DN200. Mounting is typically done using flange connections or similar standardized duct connections for DN200 pipes.

Operational advantages: The fan provides reliable air transport in ducts with DN200. The three-phase technology ensures stable rotational speed and high operational reliability. The axial flow enables efficient air movement, allowing the ventilation system to operate continuously and quietly. The construction is designed for use in industrial environments, with no additional protective measures or filters provided.
