Polyester Nonwoven for Air Pollution Control Filtration

The need for clean air to protect the human health calls for an effective removal of emissions (airborne substances) from industrial processes before being released to the environment. High efficient filtration systems (dust collectors) guarantee the removal of particulate matter from diverse industries such as cement, wood, metal, and food. Industrial baghouse installations contain numerous filter elements. Recent systems operate with pleated filter cartridges made from high performance spunbond filter media. A periodic pulse-jet cleaning removes deposited particles from the filter media surface which is crucial for a reliable surface filtration process.

"Johns Manville's Evalith^® polyester nonwoven for air pollution control provides high mechanical durability, excellent filtration performance and good processability. An optional aluminized surface treatment can be applied for providing antistatic properties. Beside the usage as stand-alone filter material, JM Evalith^® polyester nonwoven is perfectly suited as a carrier for applying additional functional coatings like highly efficient membranes. "

What is a Polyester Nonwoven?

Polyester spunbond nonwoven consists of randomly orientated filaments, thermally bonded.
Polyester bicomponent nonwoven is made of filaments with a higher melting core polyester and a lower melting sheath polyester.
