For requirements where the mechanical resistance of the filter medium is very important. Polyester fibres permit gravity filtration where solid-liquid separation occurs at high temperatures and weights.
This NONWOVEN is extremely effective in multi-layer filtration systems and in systems requiring resistance to significant amounts of pressure. Essential to activities like coolant filtration in the aluminium cutting and transformation industries.
FEATURES
Highly resistant to the pressure of continuous operation.
Very resistant to abrasion, stretching and twisting.
Resistant to a large quantity of acids and oxidants.
3D stable.
