The sludge-resistant pre-filter mat type \u00d6ko-Tex is a cost-effective addition to activated carbon filter mats or filter debris.<\/p>\n

It is durable, robust and easily replaceable. Due to the voluminous 3D structure with node stiffening and the built-in step filter – the pores are large on the side facing the flow and then become smaller and smaller – a great deal of sludge can be absorbed before the prefilter fleece becomes more impermeable to water.<\/p>\n<\/div><\/section><\/div>

The pre-filter mat made of PES is at least 13 mm thick, progressively needled with step filter and additional node stiffening. Weight per unit area approx. 350 g\/m\u00b2.<\/p>\n

The prefilter mat is available in prefabricated sizes for e.g. soakaways or drainage channels. Whole rolls are approx. 5 m wide and approx. 48 m long.<\/p>\n

Areas of application: soakaway shafts, stormwater treatment, technical filters, retention, substrate channel, drainage channel, filter basins, infiltration troughs, infiltration basins.<\/p>\n<\/div><\/section><\/div>\n<\/div><\/div><\/div><\/div><\/div>
