There is no fixed standard for the service life of a clean booth. It mainly depends on three factors: the quality of core components, the usage environment, and the maintenance frequency. Under normal circumstances, the service life range is as follows:

Ordinary configuration clean booth: Mainly composed of domestic economical fan filter units (FFU) and color steel plate frames, under general clean environment (such as food packaging, ordinary electronic assembly) and proper maintenance conditions, its service life is approximately 5 to 8 years.
High-end configuration clean booth: It adopts imported FFU, high-quality aluminum alloy frame and efficient sealing materials, and is applied in high-cleanliness requirement scenarios (such as semiconductors and biomedicine). It strictly follows maintenance regulations and has a service life of up to 10 to 15 years.
Key factors affecting service life
The core component loss FFU is the core of the clean booth, and the aging speed of its fan motor directly determines the overall lifespan. Poor-quality motors may experience increased noise and reduced air volume after continuous operation for 2 to 3 years. High-quality variable-frequency motors can operate stably for 8 to 10 years at reasonable start-stop frequencies. In addition, high-efficiency filters (HEPA/ULPA) are consumables and need to be replaced regularly (with a regular service life of 6 to 12 months). If they are not replaced for a long time, it will cause excessive load on the fan and accelerate the damage of the motor.
If the clean booth is located in an environment with high dust concentration and high humidity (such as a workshop without pretreatment), it will accelerate the rusting of the frame and the aging of the sealing rubber strips, shortening the service life by 2 to 3 years. Conversely, when used in a clean workshop with constant temperature, humidity and low dust, the rate of component wear and tear will be significantly reduced.
Regular cleaning of FFU filters, checking the sealing of the frame, calibrating the air volume of the fan, and timely replacement of aged rubber strips and filters can effectively extend the service life of the clean booth. If maintenance is neglected for a long time, problems such as air leakage and substandard cleanliness may occur, leading to the premature scrapping of the clean booth.
