We take care of engineering fundamentals
RHF engineer all impellers to be capable of withstanding imposed stresses and to be sufficiently stiff to ensure they run in perfect balance, by using finite element analysis to predict stresses and deflection on blades, shrouds, back plates, hubs, and welds.
Precisely engineer impellers, giving mass, centre of gravity and inertia to enable accurate shaft, bearing and drive design.
Check bearings for combined load, life calculations and lubrication intervals. Including motor bearing and shaft, not simply fan bearing and shaft.
We will deliver all of the above with absolute consistency through the application of bespoke software, providing an optimum engineering solution for each and every fan.
2 Style Options
We offer our fan designs in 2 styles, a universal style and a fixed style.

Frequently asked questions about Centrifugal Fans
How are Centrifugal Fans used?
Centrifugal fans are widely used in various industrial, commercial, and residential applications for ventilation, air conditioning, and cooling purposes. They are known for their ability to generate high airflow rates and deliver significant pressure increases, making them ideal for applications that require efficient air movement over long distances or against resistance, such as in HVAC systems, industrial processes, and building ventilation.
What is the difference between axial fan and Centrifugal Fan?
Centrifugal fans are widely used in various industrial, commercial, and residential applications for ventilation, air conditioning, and cooling purposes. They are known for their ability to generate high airflow rates and deliver significant pressure increases, making them ideal for applications that require efficient air movement over long distances or against resistance, such as in HVAC systems, industrial processes, and building ventilation.
Are Centrifugal Fans noisy?
Centrifugal fans’ noise levels can vary depending on factors like design and speed. Generally, they tend to be quieter than axial fans due to redirected airflow. However, noise can still be influenced by factors like motor, impeller design, and obstructions. Manufacturers provide noise specifications, and measures like insulation and proper installation can further minimise noise.
What is the advantage of Centrifugal Fan?
Centrifugal fans have advantages such as higher pressure generation, efficient airflow delivery, compact design, and reduced noise levels. These qualities make them ideal for various applications, including HVAC systems and industrial processes.
What are the benefits of using a Centrifugal Fan?
Centrifugal Fans offer a variety of advantages that make them a popular choice for many applications, especially those requiring higher pressure and more controlled airflow. Some benefits include:
• Higher pressure generation
• Flexible airflow control
• Compact design
• Noise reduction
• Efficient performance at high pressures
• Suitable for ducted systems
• Better air quality
• Energy efficiency
Test, test and test again
A commitment to proving the effect of our design thinking and production quality means that RHF test all solutions.
Our testing process involves changing inlet and impeller profiles, blade numbers, cut-off geometries and clearance. This approach has delivered significant improvements in operating efficiency for all our fans. Additionally, whilst measuring flow performance, in duct sound is also established. RHF now supply full noise spectrum figures over each products entire operating range.
