The acrylic dust collector filter bag is sewn using an acrylic filter felt, which is made of acrylic, (polyacrylonitrile), and is manufactured with the needle punching technique, followed by water repellence treatment. The needle punching felt, based on acrylic fabrics, features a great chemical corrosion resistance, hydrolysis resistance and enhanced shear strength. The acrylic dust collector filter bag is widely applicable for dust collection in waste incineration plants, bitumen mixing machines, spray dryers, coal mills and power plants.
Features
The acrylic filter media is resistant to acid, alkali, chemicals and hydrolysis.
Application
1. Dust collection in foundries
2. Dust collection in road building machinery works
3. Dust collection under low temperature and high humidity working conditions
