F7 bag filters are medium-efficiency air filters typically used in HVAC (Heating, Ventilation, and Air Conditioning) systems to capture airborne particles. These filters are categorized under the European standard EN779, which classifies them based on their filtration efficiency. An F7 filter specifically falls within the MERV (Minimum Efficiency Reporting Value) 13-16 range under the ASHRAE standard.
F7 bag filters are designed with a series of synthetic or fiberglass media pockets, resembling bags, that increase the surface area for particle capture. This allows for efficient filtering of dust, pollen, mold spores, and other fine particles, making them suitable for environments where high air quality is required, such as offices, hospitals, or industrial settings.
The key features of F7 bag filters include:
Filtration Efficiency: They typically capture 80-90% of particles sized between 0.4 and 1.0 micrometers.
Low Pressure Drop: Designed to maintain optimal airflow with minimal resistance.
Durability: Their sturdy construction allows for extended use before replacement is needed.
Applications: Commonly used in pre-filtration for clean rooms, air handling units, and industrial ventilation systems.
