Ventilateur COMPACT HCFB 4 355/HA axial-mural 41520100

Application and Mounting Characteristics

The COMPACT HCFB 4 355/HA axial fan is designed for efficient air exchange in facilities where reliability and compact construction are priorities. Its design allows for wall mounting in any position, significantly facilitating installation in challenging spatial conditions. The unit is suitable for both utility rooms and industrial halls. With a performance reaching 3490 m³/h, it effectively handles ventilation of large spaces such as:

• warehouses and storage facilities,
• workshops and production halls,
• underground and surface parking lots,
• commercial premises and greenhouses,
• breeding facilities (poultry houses, pigsties).

It is worth noting that this model is also compatible with air conditioning systems, extending its range of applications beyond general ventilation.

Construction and Resistance to Environmental Conditions

A key element of this fan is its robust housing made of steel sheet. This material has undergone an extrusion process and is protected with black epoxy paint (in some sources referred to as polyester after cataphoretic treatment), ensuring high resistance to corrosion and mechanical damage. Such a solution guarantees a long service life of the unit even in aggressive industrial environments.

The impeller is made of glass-fiber-reinforced thermoplastic (HCFT/HCFB). This material is characterized by:

• resistance to UV radiation – crucial for outdoor installation or in sunny locations,
• low self-weight while maintaining high stiffness,
• dynamic balancing compliant with the ISO 1940 standard, resulting in quieter operation and reduced vibrations.

The unit is adapted for operation within a wide temperature range: from -40°C to +70°C. This allows installation in unheated areas or locations exposed to extreme weather conditions. Relative air humidity should not exceed 95%.

Motor and Control Capabilities

The heart of this fan is a single-phase asynchronous electric motor (230 V), meeting the rigorous standards of UNE-113 and IEC 34-1. The protection rating IP65 ensures the motor is sealed against dust and water jets, making it safe for use in humid rooms or under direct exposure to rain (with appropriate mounting). Insulation class F provides an additional thermal safety margin.

The motor features built-in thermal protection of the windings against overload – a critical element protecting the drive from overheating during prolonged operation under load. Importantly for installers and end-users: the unit is standardly adapted for voltage-based speed control. This allows smooth adjustment of performance using thyristor controllers (e.g., REB series) or 5-step transformer controllers (e.g., ARW 1,5/1), enabling adaptation of airflow intensity to current needs without replacing the entire unit.

In practice, this unit achieves a rotational speed of approximately 1225 rpm with a power consumption of 200 W and a rated current of 1 A. The generated noise level is approximately 58 dB(A), and the unit mass is about 8 kg, facilitating transport and installation without the need for heavy lifting equipment.

Thanks to the combination of a solid metal construction, modern impeller material, and an advanced motor with a high protection class, the COMPACT HCFB 4 355/HA represents a universal solution requiring minimal maintenance throughout its service life. Its compact dimensions facilitate integration with existing ventilation openings without the need to expand the building structure.
