Cleanroom HVAC System FFU Fan Filtration Device for Laboratory

Core structure and functions

● Fans provide power and drive airflow. Common types include:

AC Motors: Low cost, but high energy consumption, suitable for small-scale applications.

EC Motors: Energy-efficient (30%-50% more energy-efficient than AC motors), low noise, suitable for large-scale cleanrooms.

●Filters

HEPA Filters: Filtration efficiency up to 99.97% (for 0.3μm particles), suitable for ISO Class 5 (Class 100) and above clean environments.

ULPA Filters: Filtration efficiency up to 99.9995% (for 0.12μm particles), used in ISO Class 1-3 ultra-clean environments.

Pre-Filters: Intercept large dust particles and extend the life of HEPA filters.

●Housing and Deflectors:

Housing: Supports the fan and filter. Common materials include galvanized steel, stainless steel, and aluminum alloy, providing strong sealing.

Deflectors: Optimize airflow distribution, ensuring uniform airflow and reducing turbulence.

●The control module supports functions such as speed adjustment, timing, and fault alarm. Some models can be connected to intelligent systems for remote monitoring.
