Description
The Panel Filter is engineered as a primary filtration solution for commercial, industrial, and institutional ventilation systems.
Constructed with high-quality synthetic fiber media using progressive-density technology, the filter efficiently captures larger airborne particles while maintaining excellent airflow performance. The media complies with European DIN standards and international air filtration requirements.
Its sealed-edge construction prevents air bypass and ensures maximum utilization of the filter media, helping protect secondary and high-efficiency filters while reducing overall maintenance costs.
The filter is widely used in office buildings, hospitals, shopping centers, factories, schools, and air handling units where reliable pre-filtration is required.
