Compact HCFB 4 630/HA axial wall-mounted fan 41520300

Robust ventilation for harsh environmental conditions

The COMPACT HCFB 4 630/HA axial wall-mounted fan is an appliance designed for locations where standard solutions would fail due to dust, moisture, or extreme temperatures. Its primary function is to ensure effective air exchange in industrial facilities, warehouses, production halls, and specific agricultural premises such as pigsties and poultry houses. Thanks to its corrosion-resistant and mechanically durable construction, this fan performs reliably in environments requiring continuous operation under harsh atmospheric conditions.

A key structural element is the housing made of steel sheet, which undergoes a catalytic powder coating process (polyester paint). This treatment not only enhances the appliance's aesthetics but, above all, provides long-term protection against rust and chemicals present in the air. The impeller, made of glass-fiber-reinforced thermoplastic, is resistant to UV radiation, which is crucial for installations exposed to direct sunlight. This material is also lighter than aluminum and less susceptible to chemical corrosion, resulting in reduced motor load and extended service life of the entire impeller assembly.

Applications and operating conditions

The device is adapted for operation within a wide temperature range – from -40°C to +70°C, making it a universal solution for both cold external warehouses and hot production halls or greenhouses. Relative air humidity can reach up to 95%, and the high protection rating of IP65 guarantees dust tightness and resistance to water jets. This means the fan can be installed in locations requiring frequent washing or exposed to heavy rainfall (e.g., near open warehouse doors).

In practice, this enables application in:

• Industrial facilities: production halls, repair workshops, production lines.
• Warehouses and distribution centers: both general-purpose storage and those storing goods requiring constant air circulation.
• Livestock buildings: pigsties, poultry houses, cowsheds – areas with high ammonia and moisture emissions.
• Parking lots and commercial premises: as part of general or exhaust ventilation systems.
• Air conditioning units: as an element supporting airflow in large HVAC systems.

Benefits derived from technical parameters

The single-phase motor with a supply voltage of 230V (1x230V/50Hz) allows for easy installation without the need to run a 400V three-phase line to each ventilation point. It is a four-pole unit with a rotational speed of 1380 rpm, generating a nominal airflow capacity of approximately 17 230 m³/h. Such air throughput enables rapid air exchange even in large halls without the need for complex, large-diameter ducting systems.

It is worth noting the protections integrated into the motor:

• Insulation class F ensures resistance to high operating temperatures of the windings.
• Thermal overload protection automatically cuts off power in case of critical temperature rise, protecting the device from damage and minimizing fire risk.
• IP65 protection rating safeguards the motor interior against ingress of dust and water under pressure.

Despite its high performance, the noise level generated by the device is approximately 74 dB(A), which is acceptable for most industrial environments. The external dimensions of the housing are 800x800 mm, facilitating planning of the mounting opening in a wall or partition. This fan requires no specialized tools for installation – its compact design allows for quick wall mounting in any spatial orientation.

By combining mechanical durability with high airflow parameters, the HCFB 4 630/HA model represents a solution for installers seeking reliable equipment for harsh operating conditions, as well as for end-users requiring effective ventilation without the need for frequent maintenance or repairs related to the wear of construction materials. The device features an impeller diameter of 630 mm, making it ideal for medium and large ventilation openings while maintaining a wide operating temperature range from -40°C to +70°C and resistance to
