HEPA FFU Filter Fan Unit Clean Room EFU

HEPA FFU Filter Fan Unit  Clean Room EFU

Features:

FFU filter fan unit EFU structure is ultra-thin, light weight, easy to install and maintain. Combined with the fan unit, it effectively controls the unclean air pollution inside the equipment. Low noise, low energy consumption.

3D impeller design

The company has always been a leader in the industry in terms of impeller design.

The 3D impeller is developed from a simple curved impeller with appropriate tilt and airflow analysis. The guide strips on the blades feature patented technology. The angle of tilt and the design of the guide strips are derived from extensive calculations and experiments.

Thanks to the 3D impeller, the fan achieves the required air volume at a lower speed, thereby effectively reducing noise.

Communication architecture comparison

The two systems adjust the gateway architecture by replacing the original main and sub gateways with super gateways, and adjusting the number of gateways.

The super gateway is directly connected between the switch and the FFUs, eliminating the need for a sub gateway stage. The RS485 signal is directly converted to a high-speed TCP/IP signal.

Each FFU communication port on the super gateway scans independently, improving scanning speed compared to the sequential scanning of the original sub gateways.      

The scanning speed of the original system's main gateway is directly related to the number of managed sub gateways. The more gateways, the longer the scanning period. The new structure's super gateway manages only 248 FFUs, thus maintaining a scanning period of 8 seconds regardless of the total number of FFUs in the system.
