Squirrel cage fans, also known as centrifugal fans, are vital components in a wide range of ventilation, heating, and cooling systems. Their unique design allows them to generate high pressure and airflow efficiently, making them indispensable in industrial, commercial, and residential applications. Spain, with its robust manufacturing sector and technological expertise, is home to several leading squirrel cage fan manufacturers.
Squirrel cage fans consist of a cylindrical rotor with numerous blades arranged radially around a central hub, resembling a hamster wheel or "squirrel cage." Air enters axially through the center of the fan and is expelled radially by centrifugal force. This design is particularly effective for applications requiring steady, high-pressure airflow through ductwork or ventilation systems. Their compact size, reliability, and quiet operation make them a preferred choice for HVAC systems, industrial exhaust, smoke extraction, and other air handling needs.

The manufacturing of squirrel cage fans involves several critical steps to ensure performance, durability, and efficiency:
- Impeller Fabrication: The impeller is the heart of the fan, typically produced using advanced CNC machining to achieve aerodynamic precision and balance, minimizing vibration and noise.
- Casing and Housing: Manufactured through metal forming processes such as stamping, bending, and welding, the casing must withstand high pressures and provide structural integrity.
- Motor Integration: Motors, often squirrel cage induction types, are integrated with the impeller assembly. High-quality motors with IP55 protection and efficient cooling systems are standard.
- Sealing and Insulation: Proper sealing prevents air leaks, and insulation minimizes thermal losses, enhancing overall efficiency.
- Testing and Quality Control: Advanced testing rooms and computational tools like CFD (Computational Fluid Dynamics) and FEM (Finite Element Method) simulations are employed to optimize aerodynamic performance and structural reliability.
Spanish manufacturers like LLORVESA and TECNIFAN utilize these advanced manufacturing techniques and technologies to deliver fans that meet stringent industrial standards[1][2][6][4].
