Panel Pre-Filter Mesh is mainly used to filter dust particles above 10 microns in the air, and is suitable for primary air filtration in central air conditioning systems and clean air conditioning systems.
1. The outer frame of the flat-type primary filter adopts a solid plate-type aluminum alloy frame, 10mm, 15mm, 17mm, 21mm and other thicknesses to choose from. A diamond-shaped protective net is added to the air outlet surface to ensure that the filter will not be deformed or damaged in a poor working environment; lightweight plate structure.
2. The windward area of the primary filter is increased. Dust particles in the incoming air are effectively blocked from pleat to pleat by the filter material. Clean air flows out evenly from the other side, so the airflow through the filter is smooth and even. The particle size of filtration efficiency is from 0.5pm to 5um. Flat-type primary filter can be customized.
23. The filter material is made of high-quality polyester synthetic fiber, which can be cleaned and reused many times, with long service life, economical and practical, and the fluffy and gradually dense fiber structure ensures a high dust collection rate and a large dust holding capacity, effectively prolonging the The service life of the back-end medium-efficiency filter.
4. Different thicknesses of 1 inch (21mm, 25mm) are available, and filter grades can be selected: G2, G3, G4 (EN779)
5. The maximum temperature for use is 80C, and the maximum humidity for use is 100%.
6. Filtration efficiency of flat-type primary filter: G1: 40%@5.0μm, G2: 65%@5.0um, G3: 85%@5.0um, G4: 90%@5.Oum.
