Laminar flow hood and FFU structure and features

1. Structural differences
FFU: FFU has no diffuser, air circulation is more direct, and it is suitable for local purification. Its motor is built-in, which makes its structure more compact, but also limits the size, usually not exceeding 1175*1175mm.
Laminar flow hood: The laminar flow hood has diffusers, which can evenly distribute clean air to the entire working area to achieve comprehensive air purification. Its motor is external, the size is relatively large, and larger sizes can be customized according to needs, such as 2600*2600mm.
2. Size and flexibility
FFU: The built-in motor limits the size of FFU, but also brings the advantages of high mobility and flexibility. It can be arranged and adjusted as needed and is widely used in dust-free workshops in industries such as medicine, electronics, and food factories. It is suitable for scenes that require a local high-cleanliness environment, such as specific process areas on production lines.
Laminar flow hood: The external motor makes the laminar flow hood relatively large in size and less flexible, and is usually used in fixed positions. It is often used in laboratories, pharmaceutical factories, and other places where the air quality in the working area is extremely high. It is particularly suitable for environments that require comprehensive air purification and are relatively closed.
