Industrial Medium Efficiency Bag Type Air Filter (F5-F8 Long Life & Low Resistance Type)
What is a bag type air filter (pocket filter)?
A: A bag type air filter, also a type of pocket filter, features a "bag-like" design with filter media folded into multiple vertical pockets and secured to a rigid frame. The Industrial Medium Efficiency Bag Type Air Filter (F5-F8 Long Life & Low Resistance Type) is a typical example, utilizing extremely fine chemical fibers or glass fibers as filter media, and is widely used in industrial HVAC systems.

Performance and Characteristics
Core Advantages
Classified as Medium Efficiency (F5-F8), it achieves average filtration efficiencies of 64% (F5), 70% (F6), 85% (F7), and 95% (F8) via the colorimetric method, effectively capturing airborne contaminants in industrial settings.
Designed with Low Resistance and large air volume capabilities, it ensures minimal airflow restriction, reducing energy consumption for industrial air handling systems.
Boasting a Long Life and reusable design, it can be utilized multiple times, lowering long-term operational costs and enhancing sustainability.
Function & Application
Tailored for Industrial scenarios, this filter is widely applied in pharmaceutical, electronic, and food industries for general air conditioning and ventilation. It also serves as effective intermediate filtration in air conditioning systems, removing impurities to uphold air quality and system reliability in industrial production environments.
