FILTERSOK® ....Product Information

FILTRATION - FILTERSOK® is a unique three dimensional, high flow filter with over twenty years proven performance.

INERT - FILTERSOK® is made of knitted tough polyester fibres, being more inert and resistant to degradation than nylon and organic materials.

STRONG - FILTERSOK® knitted polyester is a continuous sleeve running the entire length of the tubing, which does not require bindings, glue or ultrasonic sealing, thus resists tearing and damage during handling, shipping and installation. *

SAFE - No sharp fibres to cause damage in manual handling.

CLEAN - No dust particles during factory fitting of filter to pipe to cause problems to worker or drainage machinery. *

LIGHT - FILTERSOK® rolls can be lifted and carried manually even when wet.

LIFESPAN - FILTERSOK® exhibits equal lifespan to that of plastic drainage pipes, once installed in the ground.

INSTALLATION - FILTERSOK® is shipped in convenient roll sizes and can be fitted onto the perforated drainage pipes in one integrated operation, either at the pipe manufacturers or in the field where the system is being installed.
