The difference between impeller fit Optimal flow&Optimal size

We are pleased to inform you about our modifications to the backward curved centrifugal fans, designed specifically to meet the needs of customers with different installation conditions and size restrictions. Taking into account your unique requirements, we offer two variations: "Optimal Size" and "Optimal Flow".

The Optimal Size variant is a compact fan that will impress you with its performance. We have placed the motor inside the centrifugal fan blades to create an efficient and powerful ventilation device. Despite its reduced size compared to standard models, the "Optimal Size" delivers good performance. Its compact size makes it an ideal choice for limited installation situations where space is at a premium.

On the other hand, the "Optimal Flow" variant delivers extremely high performance. We have achieved this by mounting the fan blades so that they are located at the end of our centrifugal fan motor. The result is a powerful airflow without compromise. During our tests, we have observed that the "Optimal Flow" is capable of achieving even 20% more performance in some cases.

We invite you to visit our website where you can browse our catalog and learn more about these exciting new products. Don't miss the opportunity to take your ventilation needs to the next level!
