Ventilateur COMPACT HCFT 4 710/HA axial-mural 41520335

Application and mounting versatility

The COMPACT HCFT 4 710/HA axial wall-mounted fan is designed for high-volume air movement in large spaces. Its primary function is general ventilation of commercial and industrial premises. Thanks to its high performance, this model is suitable for demanding environments such as production halls, warehouses, distribution centers, and parking garages. It is also widely used in commercial buildings, workshops, greenhouses, and animal housing facilities. Importantly, for HVAC system designers, this fan can serve as an integral component of air conditioning units, supporting their air circulation capabilities.

The compact design of the unit allows for wall mounting in any orientation, significantly facilitating installation in locations with limited space or specific wall geometries.

Construction and resistance to external conditions

The key to the long service life of this fan lies in the carefully selected material quality. The impeller is made of glass-fiber-reinforced thermoplastic (HCFT series), which exhibits high resistance to UV radiation. Consequently, even when operating in sun-exposed areas or under direct sunlight, the impeller retains its mechanical properties and does not change color. The entire assembly is dynamically balanced according to ISO 1940, resulting in quieter operation and reduced vibrations during use.

The housing is stamped from steel sheet and subjected to multi-stage anti-corrosion protection: cathodic painting with a primer coat followed by a polyester coating. This solution ensures resistance to moisture and corrosion, which is crucial in industrial halls or warehouses with fluctuating temperatures. Fastening elements are made of stainless steel, further enhancing the aesthetics and durability of mechanical connections.

The unit is designed to operate within a wide ambient temperature range: from -40°C to +70°C. However, it should be noted that for models with diameters from Ø800 mm to Ø1000 mm (including the discussed model 710), this range is slightly reduced to -20°C to +40°C. The motor features thermal protection of the windings against overload, safeguarding it against damage in case of sudden current surges or overheating.

Installation and operational parameters

The COMPACT HCFT 4 710/HA model is a unit with an impeller diameter of 710 mm, enabling high airflows while maintaining compact housing dimensions. The unit's dimensions are precisely adapted to standard mounting openings in industrial walls – the total construction length is 900 mm, and the housing width is 800 mm. The mounting depth (height C) reaches 636 mm, requiring appropriate preparation of a wall opening with a nominal diameter of 710 mm. The external impeller diameter is 733 mm, and the mounting pitch (F) is 218.5 mm, ensuring stable fixation of the heavy unit. Additional construction dimensions include value J equal to 134 mm and the motor mounting axial parameter K at 91.5 mm.

This fan is intended for installations requiring reliable airflow without the need for complex speed control systems – two-pole motors and larger models (above specified diameters) typically operate at constant speeds tailored to the specific ventilation task. As a result, installation is simpler, and system reliability is enhanced by eliminating unnecessary control components.
