Inner rotor centrifugal fan (FFU fan) Manufacturers

The Inner Rotor Centrifugal Fan is a spindle or a motor combined with an iron core and a coil. After power on, the inner rotor fan uses the starting copper block in the motor to generate a magnetic field to work. The core feature of the inner rotor centrifugal fan is that the pressure rises quickly, which mainly depends on the width of the impeller, the air performance, and the appropriate large flow rate.
FFU Fan is a ceiling-mounted unit equipped with a fan for use in turbulent and laminar flow clean rooms. The overall design of the unit is flexible. According to the design specifications, it can easily match any ceiling frame. In order to meet the requirements of cleanliness level 1000 to level 1.
In addition, AC Fan and Air Purification Fan are also very popular products, with simple principles and wide applications.

Industry knowledge

An inner rotor centrifugal fan is a type of centrifugal fan where the rotor, or the rotating component of the fan, is located inside the impeller housing. In this design, the motor is located inside the impeller housing, which helps to make the fan more compact and energy-efficient.
The inner rotor centrifugal fan typically consists of a set of curved blades or impellers that are attached to the rotor, which is mounted on the motor shaft. As the rotor spins, the air is drawn into the impeller housing through the inlet and is accelerated by the impellers, creating a centrifugal force that drives the air outward and increases the air pressure. The high-pressure air is then discharged through the outlet of the impeller housing.
Inner rotor centrifugal fans are widely used in a variety of applications, including HVAC systems, industrial processes, and air conditioning units. The design of these fans allows for a higher pressure increase across the fan compared to an axial fan, which makes them more suitable for applications where high pressure and low volume flow rates are required.
Because the motor is located inside the impeller housing, inner rotor centrifugal fans are typically more compact and energy-efficient than external rotor centrifugal fans, which have the motor mounted outside the impeller housing. Additionally, the inner rotor design provides for greater control over airflow and pressure, making these fans suitable for a wider range of applications.
Overall, inner rotor centrifugal fans are a highly efficient and effective means of moving air, and their compact design and high-performance capabilities make them an essential component of many air-moving systems.
