The new generation of the aquarium filter bag is made of high-quality filter materials. When the liquid flows through the filter bag, the solid prticles and colloids are isolated and blocked by the filter bag on the inner surface and deep layer of the filter bag, so the filtering effect is better Conventional pore density can be divided into the following two types: 150 mesh = 0.015mm aperture (density) 200 mesh = 0.020 mm aperture (sparse) The diameter of the plastic ring of the 4-inch filter bag is 10.5cm, and the total length of the filter bag is 38cm (commonly used) The diameter of the plastic ring of the 7-inch filter bag is 18 cm, and the total length of the filter bag is 43 cm The filter bag is sealed by hot-melt method to avoid the possibility of dirt spilling from the seam gap, and there is no jumper broken. The surface of the filter bag is specially treated, and the fiber of the filter bag will not fall off after long-term use. It has high strength and can be reused for many times after cleaning. 1 Why choose Vablue Filter Bag? 1) the Acicular 100%pure fiber has the multi dimensional structure 2) Special glaze put an end to the surface of fiber to avoid secondarily pollution 3) Fully FDA compliant materials 4) Silicone Free Needled Felt 5) 11 sets of different moulds to replace nearly most kinds of the filter bagsâ?? collars (EATON/FSI/CUNO/GAF) 2 Product Technical Parameter and Detail Items Metric Unit PE PO NMO PTFE Weight per unit area g/m2 350 350 150 700 Thickness mm 2.5 3.0 0.3 1.1 Air Permeability l/dm2/min 300 300 -- 150 Tensile Strength N/5 cm MD 800 800 -- 700 CD 800 800 -- 700 Bursting Strength N/cm2 413 420 190 Heat Shrinkage % MD
