Ventilateur COMPACT HCFT 4 1000/HA axial mural 42020075

Application and Operating Characteristics

The COMPACT HCFT 4 1000/HA axial wall-mounted fan is designed for high-volume air movement in large industrial and commercial spaces. Its primary function is general ventilation where large air exchange rates are required while maintaining a compact design. This unit is ideal for warehouses, storage facilities, production halls, and workshops where rapid removal of excess heat or humidity is necessary. It is also widely used in parking garages, retail premises, and greenhouses. Thanks to its specific construction, this model is frequently employed as a component in larger air conditioning systems.

It is important to note the operating temperature range. For this specific model (1000 mm diameter), the permissible range is from -20°C to +40°C. This differs significantly from smaller units in the same series, which can operate in a wider range (down to -40°C). Consequently, installation in unheated halls with very low winter temperatures requires caution or additional protection against freezing of mechanical components.

Construction and Durability Elements

The fan is built on a robust housing extruded from steel sheet. The metal surface is protected against corrosion through cathodic electrocoating with a primer and a polyester coating, ensuring long-term resistance to environmental conditions. A key component is the impeller made of glass-fiber-reinforced thermoplastic (designation HCFT). This material exhibits high resistance to UV radiation, which is invaluable for installations exposed to direct sunlight or high-intensity artificial lighting.

The electric motor is a three-phase asynchronous unit adapted for 400 V (range 380-415 V) at 50 Hz. Insulation class F guarantees resistance to elevated winding temperatures during continuous operation. Protection class IP 55 shields the motor from dust and water jets, allowing installation in areas with increased humidity or dust. However, it should be noted that for this specific model: two-pole motors and units with diameters of 800 mm and larger (including our 1000 mm model) do not feature standard thermal overload protection for the windings nor are they adapted for voltage-based speed control in their standard configuration. If speed regulation or operation with a frequency converter is required, a special version or additional accessories must be ordered.

Performance and Key Operational Parameters

The unit delivers impressive performance of 47380 m³/h, enabling effective ventilation of large volumes even in the presence of ductwork resistance or pre-filters. The thrust generated by the fan reaches 520 Pa of static pressure, while the impeller rotational speed is approximately 1460 rpm. These high parameters result from the use of a motor with a power of 5500 W (5.5 kW), which draws a current of approximately 7.2 A at a network voltage of 3x400 V. The total weight of the unit is 95 kg, reflecting its solid mechanical construction and requiring appropriate preparation of the mounting point – the wall must be load-bearing, or additional mounting brackets must be used to transfer the fan's weight to the building structure. Installation is possible in any position thanks to the compact housing design and a dynamically balanced impeller conforming to ISO 1940, minimizing vibrations during continuous operation.
