Polyester needle punched filter felt

Polyester needle felt is the most versatile, most cost effective and most widely used

filter medium for dust collection. It is strong, abrasion resistant, can work up to 150°C

and has good resistance to common acids, solvents and oxidising agents.

Disadvantages

Polyester's only real weakness is a tendency to hydrolyse at elevated temperature

which means that moisture can break down the fibres and cause them to revert to

their basic constituents. This results in powdering of the fibres and a serious loss

of strength.

Application

Because of its favourable price/quality ratio, polyester is the most common fibre used

in filter media.

• Mining • Cement Industry • Iron and Steel Industry • Aluminum and Non Ferrous Industry • Ceramic Industry • Quarrying • Plastics • Milk Powder • Flour Mills (Applications under dry conditions up to temperatures of 150°C)
