Down-detachable FFU with Geal Seal HEPA filter is a new type of FFU specially developed by our company according to the strict requirements of the GMP clean workshop of some pharmaceutical factories. Its FFU fan and high-efficiency filter are detachable.
FFU fan filter unit is to purify the air sent into the clean area to meet the requirements of clean environment. It is installed on the ceiling keel (T-Grid) of the clean area or work area or on the equipment machine, and has a wide range of uses. FFU fan filter unit is mainly used in semiconductors, liquid crystal displays, optoelectronics, precision instruments, chemistry, biomedicine, hospitals, food, research institutes, universities, aerospace, automobiles, coating, printing and other fields.
1.The bottom of the filter-separated FFU adopts a special design of fixings, which allows single-person operation when installing, disassembling and replacing filters, which is convenient and quick.
2. The high-efficiency AC centrifugal fan is used, and the average wind speed is increased by 25%. The overheat protection capability is good, which effectively reduces the loss.
3 The wind speed is stable and the service life is long. It is suitable for clean rooms with cleanliness Class 1-1000.
4. It is particularly suitable for assembly into ultra-clean production lines. It can be arranged as a single unit according to process requirements, or multiple units can be connected in series to form a 100-level assembly line.
5. The unique liquid tank sealing method, with its own PAO dust outlet and concentration sampling port, fully meets the requirements of the new version of GMP-E specifications. Lightweight and thin body, more convenient for application in small areas.
Lightweight modular structure design, suitable for installation of ceiling keel (T-Grid) system of various manufacturers;
High-performance motor with double overload protection, high static pressure, low noise, low energy consumption, saving operating costs; Low noise, the source is the scientific motor and air guide structure design, so that the noise level of the product is lower than that of similar products;
Even air discharge, uniform wind pressure diffusion and meet the requirements of international standard IES-RP-CC002 +/- 20%;
Low micro-vibration, the total vibration rate is less than 1mm/s, and the amplitude does not exceed 3um;
Flexible control mode, can be used for single-speed, three-speed, five-speed or stepless speed regulation to adjust the air volume and attached with operation/abnormal indicator light/abnormal dry contact for easy monitoring; Various special specifications and sizes can be customized;
Pre-filter (G3-G4) and Chemical molecular filter Can be equipped with abnormal indoor fault LED lights;
Can be equipped with differential pressure gauges, wind speed sensors, etc.;
Can be equipped with a small 99-unit monitoring system or a large remote central monitoring system

The monitoring system is easy to operate, can monitor FFU on the computer, has strong anti-interference and low construction cost
The system adopts MODBUS communication protocol, is designed based on RS485 bus, and is controlled in four levels.
The system can control more than 8,000 units at most. .
Working power supply: AC 220V single phase 50HZ
Control function: can realize single or group control FFU on the controller
a. Start b. Stop c. Three-stage speed regulation
Monitoring function: can monitor single or group control FFU on the controller
a. Running status b. Fault status
The working principle is the same as that of ordinary FFU. The fan sucks air from the top and evenly distributes clean air after filtering through the high-efficiency filter, providing clean air and particle filtration control for the clean environment.
The bottom-detachable FFU is widely used in semiconductor, electronics, flat panel display, disk drive manufacturers and optical, biological industries, etc., clean production lines, clean workbenches, clean rooms, assembly clean rooms and laminar flow hoods.
