Absolute Consistency
We take care of engineering fundamentals.
RHF engineers 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, a 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.
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 an axial fan and a 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. Due to redirected airflow, they tend to be quieter than axial fans. However, noise can still be influenced by factors like motor, impeller design, and obstructions. Manufacturers provide noise specifications; 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?
