How do I clean and maintain the FFU tank?
How do I clean and maintain the FFU tank?Disassembled liquid tank FFU, also known as liquid tank sealed FFU, is a new type of FFU specially developed according to the strict requirements of GMP clean workshops in some pharmaceutical factories. The following will be introduced from its working principle, product characteristics, application fields, and other dimensions:Working principle: The fan inhales the air from the top and sends the clean air out evenly after it is filtered by the high-efficiency filter to provide clean air and particulate filtration control for a clean environment. Product characteristics Convenient disassembly: The bottom of the filter separation FFU adopts a special design of fixed parts, which makes it convenient and quick to install, disassemble, and replace the filter. High efficiency and energy saving: Using a high-efficiency AC centrifugal fan, the average wind speed increases by 25%, has good overheating protection ability, and effectively reduces loss. Stable performance: stable wind speed, long service life, suitable for cleanliness classclassclass1 -1000 clean room. Flexible arrangement: It is especially suitable for assembling into a super-clean production line, which can be arranged as a single set according to the process needs, or multiple sets can be connected in series to form a 100-level assembly line. Good sealing: Unique liquid tank sealing mode, with PAO dust outlet and concentration sampling port, fully meets the requirements of the new GMP-E specification. Thin design: lightweight, thin body, more convenient in small areas of application. Various materials: the shell material is usually stainless steel, aluminum-coated zinc plate, steel spray plastic, etc., to meet the needs of different environments. Applications: Widely used in semiconductors, electronics, flat panel displays, disk drive manufacturers, and optical, and biological industries, as well as clean production lines, clean workbenchs, clean rooms, assembled clean rooms and laminar flow hoods, and other places. Technical parameters: Liquid tank sealed FFU/disassembled FFU can be customized according to the actual needs of users, common HEPA sizes are 570X570X110, 1170X570X110, 1170X1170X110, and so on. Care and maintenance Periodic inspection: Periodically check the appearance of the FFU to see if any parts are loose, damaged, or corroded to ensure that the overall structure of the equipment is intact. At the same time, check the sealing condition of the liquid tank to prevent leakage problems from affecting the filtration effect. Clean the filter: Clean or replace the HEPA filter regularly according to the environment and frequency of use. When the resistance of the filter reaches a certain limit, it should be replaced in time to ensure the normal operation of FFU and filtration efficiency. Fan maintenance: Check the fan running status, including the fan speed, noise, and vibration. Add lubricating oil to the fan regularly to ensure that the bearing and other components of the fan run smoothly and extend the service life of the fan. Electrical system inspection: Check whether the electrical connection of FFU is firm, whether the wires are damaged, aging, and other phenomena. At the same time, check the insulation performance of the motor to ensure the safe operation of the electrical system. |
