What is the service life of an industrial FFU fan?
The service life of an industrial FFU fan is affected by many factors. Based on industry standards and actual applications, the main conclusions are as follows:
Design Life Standard
The design service life of an FFU fan-filter unit is typically at least 50,000 hours (approximately 5.7 years of continuous operation). Some high-quality models can reach 100,000 hours (approximately 11.4 years) with proper maintenance. This standard is based on the technical parameters of imported high-efficiency centrifugal fans, such as EBM AC fans.
Key Influencing Factors
Fan Type: DC systems consume 30%-50% less power than AC systems and have a longer service life.
Load Conditions: Long-term operation exceeding rated loads can significantly shorten service life.
Maintenance Frequency: Regular cleaning and lubrication can extend service life by 20%-30%.
Environmental Factors: Corrosive gases or high temperatures can accelerate component aging. Maintenance Recommendations
Daily Inspection: Clean the primary filter monthly and check the HEPA filter differential pressure every six months.
Professional Maintenance: Perform a comprehensive electrical system inspection at least annually. Lubricate the fan bearings every 200 hours for the first replacement and every six months thereafter.
Replacement Standard: Replace the HEPA filter when its resistance reaches 1.5-2 times its initial value or when the air outlet surface becomes black (usually every 1-2 years).

Industry Differences: Due to the continuous operation requirements of FFUs in the electronics industry, their actual lifespan may be shortened to 3-5 years. In the pharmaceutical industry, with rigorous maintenance, they can reach over 8 years. Testing standards such as JG/T388-2012 clearly define cycle testing requirements for durability.
