GXF Type Inclined Flow Fan

The GXF Type Inclined Flow Fan represents a significant advancement in ventilation technology. Developed as a derivative of the SWF fan series, this fan stands out for its innovative application of the meridional acceleration design method. But what does that actually mean in practice? Let us break it down.

Traditional axial fans move large volumes of air but struggle when faced with duct resistance—they simply cannot generate enough pressure to push air through long runs of ductwork. Centrifugal fans, on the other hand, excel at generating high pressure but are bulky, noisy, and often less efficient for moving large air volumes. The GXF Inclined Flow Fan solves this dilemma by combining the best of both worlds.

The secret lies in the fan's unique geometry. GXF Fan features a drum-shaped or straight casing, a tapered hub, and twisted wing-shaped blades. The tapered hub design reduces the relative diameter at the inlet, which accelerates airflow in the meridional plane. This acceleration reduces the static pressure gradient within the flow path, effectively preventing airflow separation. The result? Higher pressure coefficients without the efficiency losses that typically plague conventional fan designs.

What this means for you is straightforward: the GXF Inclined Flow Fan delivers higher airflow than centrifugal fans of the same size, while generating greater static pressure than axial fans. It essentially gives you the ventilation performance you need in a more compact package. The fan's flow channel design increases axial velocity, which reduces the static pressure gradient and avoids flow detachment—giving you a higher pressure coefficient and better overall efficiency.

GXF Fan is built for real-world conditions. It operates reliably in temperatures ranging from -20°C to +80°C and can handle air with dust content up to 100mg/m³. The fan is available in sixteen different diameters from 300mm to 1400mm, with airflow capacities ranging from 1,500 to 110,000 m³/h and static pressures from 95 to 2,500 Pa. Whether you need a compact unit for a small equipment room or a high-capacity system for a large industrial facility, there is a GXF configuration that fits your needs.

The GXF Series can be divided into six types according to their configurations: A, B, C, D, E, and F, with a wide range of parameters and convenient selection to meet the requirements of different working conditions.

High Airflow and Pressure

 – The GXF Inclined Flow Fan combines the advantages of both axial and centrifugal fan technologies. It delivers efficient airflow while maintaining higher static pressure than conventional axial fans, making it ideal for ducted systems where resistance is a concern. In the same fan size, GXF Fan delivers greater flow than centrifugal fans and higher pressure than axial fans.

Energy Efficiency

 – The optimized airflow channel design improves ventilation performance while reducing energy consumption. The fan's efficient aerodynamic profile means you move more air with less power—a direct benefit to your operating budget. The broad high-efficiency operating range ensures you are not paying for wasted energy during off-peak conditions.

Low-Noise Operation

 – Advanced impeller design minimizes vibration and operating noise. Noise levels are kept below 75dB(A), making GXF Fan suitable for noise-sensitive environments like hotels, hospitals, and office buildings where occupant comfort matters. Optional silencers and sound-insulated enclosures are available for applications with strict noise requirements.

Robust Construction

 – Heavy-duty steel housing provides excellent durability and corrosion resistance. Every impeller undergoes dynamic and static balancing to ensure smooth operation, minimal vibration, and extended bearing life. The motor is IP54-rated with Class F insulation for reliable performance in demanding conditions.

Easy Installation

 – The compact structure allows convenient installation in tight spaces. The fan supports horizontal, vertical, and ceiling-mounted configurations, giving you flexibility in system design.

Customization Available

 – Custom airflow, pressure, dimensions, motors, and speed control options are available. The fan can be equipped with single-speed, dual-speed, or variable frequency drive (VFD) motors for precise speed control. VFD operation is recommended within the 25Hz to 50Hz range for optimal performance and motor protection. Optional accessories include silencers, control boxes, and vibration dampers.

Special Configurations

 – GXF Fan can be manufactured in corrosion-resistant versions for handling aggressive gases, explosion-proof configurations (ExdIIBT4) for flammable or explosive environments, roof-mounted units for outdoor installation, and silenced versions with external silencer boxes.

Commercial Buildings

GXF Fan is widely used in office buildings, shopping malls, hotels, and commercial complexes. Its low-noise operation makes it particularly suitable for guest rooms, conference areas, and retail spaces where a quiet environment is essential. The fan handles both supply air and exhaust duties in HVAC systems, ensuring comfortable indoor air quality for occupants.

Industrial Facilities

In factories, warehouses, workshops, and logistics centers, GXF Fan provides robust ventilation for heat removal, fume extraction, and general air circulation. The fan's high static pressure capability makes it ideal for ducted systems with significant resistance, while its durable construction withstands demanding industrial conditions.

Underground Facilities

Parking garages, equipment rooms, and civil defense projects benefit from GXF Fan's compact design and reliable performance. The fan moves large volumes of air efficiently in confined spaces where traditional centrifugal fans would be too bulky.

Public Buildings

Hospitals, schools, airports, stadiums, and exhibition centers rely on GXF Fan for consistent, quiet, and energy-efficient ventilation. The fan's broad high-efficiency range ensures optimal performance across varying occupancy and load conditions.

Pipeline Pressurization

GXF Fan is particularly well-suited for pipeline pressurization, supply air, and exhaust in high-rise buildings and general building ventilation. Its compact size makes it ideal for installations where space is limited. 

The GXF Type Inclined Flow Fan is designed for supply air, exhaust air, and air circulation in HVAC and industrial ventilation systems. It improves airflow efficiency, enhances indoor air quality, and provides stable ventilation performance under various operating conditions.

The fan's primary functions include:

• Supply Air – Delivering fresh, conditioned air into occupied spaces

• Exhaust Air – Removing stale air, contaminants, heat, and moisture from enclosed areas

• Air Circulation – Maintaining consistent air movement throughout a facility

• Pipeline Pressurization – Boosting air pressure in ducted systems to overcome resistance

By combining high airflow with superior static pressure, GXF Fan ensures effective ventilation even in complex ducted systems where resistance is a concern. Its energy-efficient design means you get the ventilation performance you need without excessive energy consumption.
