1, nylon monofilament net bag

Nylon monofilament mesh bag made of high quality nylon monofilament mesh sewing, each silk thread is welded and fused to increase its strength,

To keep the thread from bending under pressure. The joint edge of the sewage filter bag is stretched and the steel ring at the mouth of the bag is strengthened. Based on the principle of surface filtration, nylon monofilament filter bag separates particles larger than its own net from filtrate. It can be used with the appropriate filtration device to effectively obtain the desired filtration effect.
