Compact HCFT 4 710/HA axial wall-mounted fan 41520335

Application and Mounting Versatility

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

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

Construction and Resistance to External Conditions

The key to the long service life of this fan is the carefully selected material quality. The impeller is made of glass-fiber-reinforced thermoplastic (HCFT series), characterized by high resistance to UV radiation. As a result, even when operating in sun-exposed areas or under direct sunlight, the impeller does not lose its mechanical properties nor 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 primer and a polyester coating. This solution ensures resistance to moisture and corrosion, which is crucial in industrial halls or warehouses with variable temperatures. Fastening elements are made of stainless steel, further enhancing the aesthetics and durability of mechanical connections.

The device is designed for operation 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 narrowed to -20°C to +40°C. The motor features thermal protection of the winding 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 air flow rates while maintaining compact housing dimensions. The device 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 spacing (F) is 218.5 mm, ensuring stable fixation of the heavy unit. Additional construction dimensions include value J equal to 134 mm and the axial motor mounting parameter K at 91.5 mm.

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