Inline Square Centrifugal Fan – YFISQ/ISQ

Industrial Ventilation INFINAIR

Inline Square Centrifugal Fan – YFISQ/ISQ

The YFISQ/ISQ is an inline square design centrifugal fan, ideal for demanding industrial and commercial applications. It offers a high-efficiency, low-noise solution with great installation flexibility, standing out for its robustness, ease of maintenance, and compliance with the highest international quality standards.

Equipment Overview

This equipment represents the 4th generation of INFINAIR centrifugal fans, designed to overcome the limitations of conventional axial or mixed-flow fans.

View full description ▼

Its square structure eliminates the need for round connectors, drastically reducing installation and ductwork costs. By dispensing with a scroll, the air is pressurized directly in the wheel, optimizing the flow pattern and allowing for a more compact design.

Thanks to its CFD (Computational Fluid Dynamics) simulation technology and FEA (Finite Element Analysis) analysis, this fan guarantees superior aerodynamic performance, significant noise reduction, and an extended service life. It is an ideal option for environments requiring controlled spaces, such as cleanrooms, food industries, and medical facilities.
