Vent Filter

Vent Filters (short for Ventilation System Air Filters) constitute a significant product line for 3F. Our vent filters primarily include the following key variants:

PF (Pre-Filter)
MEF (Medium Efficiency Filter)
HEPA (High Efficiency Particulate Air Filter)
ULPA (Ultra Low Penetration Air Filter)
ACF (Activated Carbon Filter)
These filters are engineered to meet diverse air purification requirements and are widely applied in critical sites such as:

HVAC systems (Heating, Ventilation, and Air Conditioning)
Cleanrooms
Healthcare facilities (e.g., hospitals and laboratories)
Electronics manufacturing facilities
Industrial production zones
The selection of a proper vent filter type is determined by its filtering efficiency, which aligns with specific operational standards and particulate control demands.
