Selecting better media for your pleated bag and cartridge filters
For pleated bag and pleated cartridge filters, it's easy to get confused by the multiple choices in filter media. But the right choice can often bring big improvements in filtering efficiency, service life, and dust release. This article describes how to recognize opportunities for improving dust collection in your plant by upgrading the pleated filter media in your existing baghouse or cartridge dust collector. A comprehensive table compares performance characteristics and other factors for filter media in three main categories -- wet-laid, needled-felt, and spunbonded.
There's wet-laid filter media -- cellulose or synthetic, fire-retardant or not. There's polyester media -- needled-felt or spunbonded, metallized or carbon-impregnated. There's acrylic needled felt, Nomex needled felt, Ryton needled felt, and P-84 needled felt.
