The air flow (free air) of the 3258JH3P fan is 270 m³/h, making it the most powerful model in the new fan series. The 3258JHHP generates an air flow (free air) of 235 m³/h.
In contrast to the 3200J (S-Force), the fan operates optimally in a slightly higher air flow range and is suitable for lower back pressure. This opens up new areas of application that demand a lower noise level.

Features
In order to improve aerodynamic performance, we have got rid of the balance pockets used previously. Instead, milling in the magnet enables the rotor to be balanced.
Other technological developments include:
- Robust housing made of glass-fiber reinforced plastic
- New high-performance motor
- Impeller noise reduction thanks to
- new aeroacoustic design
- Turbulator
- Improved environmental performance
- Lower power consumption
- Efficiency increase compared to 3200J
Efficiency
For example, at certain operating points, the 3258JH3P (S-Panther)’s is up to 3% more efficient than its comparable predecessor, 3218JH4P (S-Force) thanks to a number of optimizations.
Noise
One of the strengths of the 3250J (S-Panther) is its improved noise characteristics. This is primarily due to the new aeroacoustic design of the impeller and the turbulator. This significantly reduces the speed with almost the same air flow. Therefore, the 3250J (S-Panther) is up to 4 dB(A) quieter.
