Fiberglass Composite Filter Paper
This is a filter paper made of micro fiberglass mat single - or double-sided composite with polyester non-woven fabric protective layer. The structure can avoid secondary pollution caused by the falling off of the filter layer. Used to filter air and liquid, the product has high filtration efficiency, low resistance, high strength and large dust capacity. Filter impurities in the particle size of 1 ~ 70um, 1m wide of the finished product, delivery by roll.
Liquid filtration accuracy:1um, 2um, 3um, 5um, 10um, 20um, 25um, 30um, 40um, 50um, 70um;tensile strength:(KG/15MIN/):≥2.5
Air filtration accuracy:1um,5um,10um,25um;tensile strength:(KN/M):≥2.5;The filtration efficiency:65%, 90%, 99%, 99.9995%
Fiberglass air filter paper is made of glass fibers as main raw material by wet process. Characterized by stable property, uniform fiber distribution, high dust holding capacity, high efficiency, low air resistance and high strength, it is an ideal material for air filtration. Depending on the filtering efficiency, the products are divided into three series (ASHRAE, HEPA and ULPA).
| Class | Grade | Efficiency | Resistance | Tensile Strength | Thickness | Basic Weight | Stiffness |
| HEPA 0.3mm @5.3cm/s | H14 | ≥99.995% | ≤420Pa | 1.0-1.25KN/m | 0.33±0.02mm | 74±4g/m2 | mg≥1000 |
| H13 | ≥99.97% | ≤330Pa | 0.9-1.20KN/m | 0.33±0.02mm | 74±4g/m2 | mg≥1000 | |
| H12 | ≥99.8% | ≤260Pa | 0.9-1.20KN/m | 0.33±0.02mm | 74±4g/m2 | mg≥1000 | |
| H11 | ≥98% | ≤180Pa | 0.9-1.20KN/m | 0.33±0.02mm | 74±4g/m2 | mg≥1000 | |
| H10 | ≥94% | ≤120Pa | 0.9-1.20KN/m | 0.33±0.02mm | 74±4g/m2 | mg≥1000 | |
| ASHRAE 0.4mm @5.3cm/s | F9 | ≥95% | ≤80Pa | 0.9-1.15KN/m | 0.33±0.02mm | 70±4g/m2 | mg≥900 |
| F8 | ≥90% | ≤60Pa | 0.9-1.15KN/m | 0.33±0.02mm | 70±4g/m2 | mg≥900 | |
| F7 | ≥80% | ≤40Pa | 0.9-1.15KN/m | 0.33±0.02mm | 70±4g/m2 | mg≥900 | |
| F6 | ≥60% | ≤25Pa | 0.9-1.15KN/m | 0.33±0.02mm | 70±4g/m2 | mg≥900 |
