Compressed air filters, often called in-line filters, are used to remove contaminants from compressed air after compression has occurred.When a filter is combined with a regulator and oiler, it is called an air unit. [1]The air leaving a standard screw or piston compressor is often high in water and

Recent emphasis on extremely high-efficiency removal of very fine particles during filtration has led to the demand for very fine porous surface layers, and this demand has been met by the lamination of a membrane on to a suitably robust substrate.

Composite non-woven fabric is a kind of fabric without spinning and weaving. It is only made by directional or random support of textile short fibers or filaments to form a fiber web structure, and then reinforced by mechanical, thermal bonding or chemical methods. In short, it is not interlaced and

It is reported that the material composition of the non-woven fabric industry is roughly: 63% polypropylene, 23% polyester, 8% viscose, 2% acrylic fiber, 1.5% polyamide, and the rest are other fibers.Because the reuse rate of composite non-woven bag is much higher than that of plastic bag, it is ver
