Introduction to FFU/laminar flow hood
FFU stands for Fan Filter Units, which means "Fan Filter Units" in Chinese. More precisely, it is a modular end air supply device with built-in power and filtering function. The fan sucks in air from the top of the FFU and filters it through HEPA. The filtered clean air is evenly sent out at a wind speed of 0.45m/s ± 20% on the entire outlet surface.

FFU can be modularly connected and used, making it widely used in cleanrooms, cleanroom workstations, cleanroom production lines, modular cleanrooms, and local Class 100 applications.
characteristic:
1. There are multiple ways to control speed.
2. Extremely low operating power consumption, reducing costs. 3. Built in air duct guidance system reduces noise and pressure loss, and improves fan efficiency.
4. It can easily be paired with various brands of T-GRID, HEPA, and ULPA.
5. The German EBM original rear tilting centrifugal fan can provide high air volume and high static pressure conditions, with a working life of over 50000 hours.
6. Suitable for use in cleanrooms with a cleanliness level of Class 1-1000.
7. Specially suitable for assembling into ultra clean production lines, it can be arranged as a single unit for use according to process needs, or multiple units can be connected in series to form a 100 level assembly line
8. Before leaving the factory, the products are scanned and tested one by one using a dust particle counter in accordance with the US Federal Standard 209E to ensure quality.
