Ventilateur axial TCBT 4 800/GB pour conduit, rotor en aluminium 42020157

Application and Operating Characteristics

The TCBT 4 800/GB axial fan is a device dedicated to high-volume air flow in large duct installations. Its primary function is general ventilation in high-volume facilities such as production halls, large warehouses, underground parking lots, or logistics centers. Thanks to its design adapted for direct installation within ducts, the device effectively exchanges air in mechanical ventilation systems, handling loads typical of industry and large commercial areas.

The device is characterized by high performance – at a rotational speed of approximately 1475 obr./min, it achieves an airflow of 42 490 m³/h. This power enables rapid moisture evaporation, odor removal, or room cooling even with significant system resistance. The three-phase motor (400V) with a power of 7,5 kW ensures stable continuous operation, while the possibility of frequency regulation (via an inverter) provides installers with flexibility in adjusting performance to the facility's current needs, resulting in energy savings.

Construction and Resistance to Environmental Conditions

Robustness of construction is crucial for devices operating in harsh conditions. The fan housing is made of steel sheet, protected against corrosion through cataphoretic painting (primer) and a polyester layer. Such a solution guarantees long service life even in environments with elevated humidity or the presence of aggressive chemical factors.

A key structural element is the impeller made of aluminum sheet. It has been dynamically balanced according to the ISO 1940-1 standard, minimizing vibrations during operation and reducing the noise level generated by the device. Airflow occurs in the direction from the impeller to the motor (HB version), protecting the drive from direct contact with the conveyed medium.

The device meets rigorous safety requirements thanks to an protection rating of IP 55, which ensures effective protection against dust and water jets falling from any direction – this is essential when washing halls or operating in industrial conditions. The motor is equipped with class F insulation, allowing it to operate at higher temperatures without risk of winding damage. The temperature range of the conveyed medium is from -40°C to +40°C, making the fan a universal solution for both cold and temperate climates.

Installation and Technical Compatibility

The TCBT 4 800/GB fan has been designed to facilitate installation in existing ventilation systems. It features standard dimensions allowing connection to ducts with a diameter of 800 mm. The entire unit weighs approximately 89 kg, requiring appropriate preparation of the supporting structure or suspension during vertical or horizontal installation.

For installers, the electrical connection and control are also important: the device is powered by 3-phase 400V / 50Hz voltage. Rotational speed can be regulated using an inverter (external controller required), allowing precise adjustment of flow intensity to the requirements of the ventilation project without the need for additional mechanical dampers – this model does not have built-in voltage regulation available in smaller versions. The connection box is located directly on the housing, shortening wiring installation time.

Summarizing the key technical data of the device: the nominal diameter is 800 mm, and maximum performance reaches 42 490 m³/h. The drive consists of a three-phase motor with a power of 7,5 kW operating at 400 V. The fan features a protection rating of IP 55 and insulation class F, allowing operation with a medium at temperatures from -40°C to +40°C. The impeller rotational speed is approximately 1475 obr./min, and the construction material is dynamically balanced aluminum with airflow direction from impeller to motor (HB).
