Filter damage caused by abrasive sand is not necessary

Save on clean-up costs by using PureFlow®. Sand is
abrasive and damages/contaminates filter housings, filter nozzles, pipes,
sliders, valves and pumps. 

Unlike sand, PureFlow® high-tech fibers are non-abrasive and do not cause any damage to the entire filter system. This saves cost-intensive refurbishment of filter systems.

Comparison PureFlow® vs. sand

Liquid must be passed through a filter with high selectivity and low resistance. PureFlow® fulfills these requirements 100%.

Solids contamination filtered out and made visible with PureFlow® after normal sand filtration.
