What's the difference between FFUs and air showers?

In the realm of cleanrooms, FFUs (Fan Filter Units) and air showers are two common pieces of equipment. While both are related to the supply and control of clean air, they have distinct functions, applications, and design principles.

1. Functional Differences

FFUs: These are air purification devices used within cleanrooms. They deliver clean air downward through built-in fans and high-efficiency filters, creating a localized dust-free environment. FFUs find wide application in industries with stringent cleanliness requirements, such as electronics, semiconductors, and biopharmaceuticals.

Air Showers: Designed as transition chambers, air showers are used before personnel or objects enter a cleanroom. By subjecting them to high-velocity air jets, they effectively remove surface contaminants to prevent external contamination from entering the clean zone.

2. Design Principles

FFUs: Typically installed on cleanroom ceilings, FFUs offer a modular design for flexible configurations to meet various cleanroom needs. They maintain positive pressure and cleanliness within the cleanroom through continuous airflow.

Air Showers: Employing high-pressure air jets, air showers provide 360-degree coverage to ensure maximum contaminant removal.

3. Application Scenarios

FFUs: Primarily used to supply clean air, FFUs are suitable for areas requiring high levels of cleanliness, such as semiconductor fabrication plants or laboratories.

Air Showers: As the "gatekeepers" to cleanrooms, air showers are usually positioned at cleanroom entrances or material transfer areas to safeguard the cleanroom environment from external contamination.
